LONDON : NAPIER, PRINTER, SEYMOUR STREET, EUSTON SQUARE. MDCCCLXXXIV. Ea veales Livan Ce Four years ago (May, 1880), when concluding the preface to the original work (with its two Supplements and Appendix), these words were written :— ‘“T hope to continue the Supplement from time to time.” A “First Additional Supplement ” is now (June, 1884) brought before the notice of students of these insects. I am enabled to add nearly fifty species to those described in the original work and its Supplements ; some new forms are noticed to which it has been considered prudent to (at least provisiunally) assign the rank of varieties ; and there is much additional local information. This latter part of the subject might have been extended indefinitely ; therefore, a selection had to be made, and the local information here given refers (as a rule) only to countries or districts in which the particular species mentioned had not pre- viously been noticed. All the species in the original work have passed under review, and, in one or two instances, entire genera have been revised. Very few new genera are indicated. I think the time has scarcely arrived for a generic re-distribution, or, it would be better to say, a sub- division of some of the larger generic groups as now constituted. Of the additional species here indicated, all but about six are from within the limits of Europe proper, a significant fact, and proving that it would be unsafe even to hazard a conjecture as to the number of those forming part -of the “ European Fauna,” Most of my former correspondents continue to help me, and the valuable assistance of others has been secured. To all I tender my hearty thanks, and think I have acknowledged the aid thus accorded in all cases in the course of this Supplement. iv. PREFACE. But again, and more than ever, are my thanks specially due to my friend the Rey. A. E. Eaton, for it is owing to his various travels in Portugal, Italy, Madeira, the Canary Islands, &c., that more than three-fifths of the new species herein described became known to me. If a foreigner making short holiday tours through certain districts previously unexplored (so far as these insects are concerned) can produce such results, it is needless to call attention to what might be done by residents in the districts. The general plan adopted in the original work, both as regards text and plates, has been adhered to; it appears to have answered the purpose intended, even if there exist, in some cases, doubts as to the morphological correctness of the terms used. I have been fortunate in being able to again secure the services of Mr. Jarman, who engraved the plates in the original work, and who has done justice to my own poor artistic powers, so far as the style of engraving adopted would permit. Once more—I hope to continue the Supplement from time to time. But as the necessities for prompt publication of new discoveries become daily more unperative, it is possible that a “Second Additional Supplement”’ may consist, more than does this “ First,” of collected information previously pub- lished in a scattered form. R. McLACHLAN. Lewisham, London : 2nd June, 1884. FIRST ADDITIONAL SUPPLEMENT. Fam. PHRYGANEHIDA., Wallengren, in 1880, published a synopsis of the Scandinavian species of _ this Family under the title, “Om skandinaviens arter af familjen Phryganeide ” . (Entomologisk Tidskrift, i, pp. 64—75), in which he attempted more minute generic sub-division. The scheme is tolerably natural so far as it goes, but it is mainly based on certain minute neural characters very difficult to seize, and, ~~ if my ideas be correct, not with due regard to the homologies of neuration.* The characters drawn from occult neural differences at the extreme base of the ~ posterior-wings are of extreme obscurity, and I confess to not having been able to follow the author in his details. The presence or absence of a transverse -nervule between the costa and sub-costa is used by him for primary sub-division, as by me (cf. p. 14). A second important division is effected according to the ; point of origin of the sectors arising from the discoidal cell (my nomenclature), by means of which he separates Neuronia phalenoides and atrata from all the others (excepting Agrypnia). Then follow minor sub-divisions. The result is | that we get the following generic sequence :—1. Holostomis, Mannerh. (= . phalenoides and atrata); 2. Oligostomis, Kol. (= N. Stalit, reticulata, melan- % optera, n. sp., and clathrata) ; 3. Neuronia, Leach (= lapponica and striata » [rufierus]) ; 4, Phryganea, L. (= grandis and bipunctata [striata]) ; 5. Dasy- 3 stegia, Walleng. (= vartegata [varia] and obsoleta) ; 6. Trichostegia, Kol., oy Hag. (= minor); 7. Agrypnia, Curt. (= picta and Pagetana). ~w These divisions are natural enough so far as they go, and I had already tt called attention to them in the course of my remarks on the genera in the ’ “Revision and Synopsis,” but as the Family is only of very limited extent, as ~ compared with some others, it seemed best at that time (and seems so still) ~ to await a new generic revision of the whole before making a partial puis based on a local fauna. The latter having been done, I accept it toa certain extent, retaining my original sequence, using Wallengren’s subsidiary divisions as “sub-genera”’ or sections, and basing these divisions upon charac- ers more easy to seize than are those used by Wallengren. z oh lex ? ~w Se. ~ * It should he here remarked that the terminology of neuration used by Wallengren is based upon that of 3 Sundeval, which has met with little acceptance outside Sweden ; and it is very misleading to entomologists not acquainted with the peculiar nomenclature : for instance, the “‘ areola discoidalis” is not. the ° discoidal t\. cell” of other authors, but the area below it (or between it and the superior cubitus), the ‘‘ discoidal cell of my work representing the “‘ areola subradialis”” of Wallengren, Iam indebted to the author for a diagram indicating the terminology used. 24 First ADDITIONAL SUPPLEMENT.

AGRYPNIA.* On this principle the species of Phryganeide in the European Fauna may be arranged in groups as follows :— NEURONIA.

AGRYPNETES. erassicornis, McLach. NOTES. Neuronia (Wallengr.).—Wallengren separates this from its near allies on an obseure structure (uncertain to me) in the neuration of the extreme base of the posterior-wings. Much more obvious characters exist in the anal parts of the g, and in the fact that apical fork No. 3 in the posterior-wings of the @ extends to the anastomosis. The two species have very much in common, not- withstanding the great difference in coloration. * JT have not included the extraordinary Agrypnetes crassicornis (cf. Supplement, p. ii) in this table, its characters being altogether aberrant. I have uo further information respecting it, and the entomologists of Finland must decide whether the type is, or is not, an unnatural hybrid; a monstrosity it can scarcely be on account of the symmetry of all its structure. PHRYGANEID 2D. 3 Oligostomis (Wallengr.).—In Kolenati’s signification this included New- ronia and Oligostomis of Wallengren. The latter founds it on a corresponding, but varying, principle to that which determined his definition of Mewronia. The fact that apical fork No. 3 does not extend to the anastomosis in the posterior- wings of the ? separates it from Neuronia (Wallengr.), as do also the anal appen- dages of the ¢ ; but with regard to the latter character there are two distinct groups represented respectively by reticulata (with Staliz) and clathrata (with melanoptera), and on anal characters they could not remain in the same division, notwithstanding their extreme outward resemblance. Holostomis (Wallengr.).—With this Wallengren heads his Synopsis, and bases it on the origin of the apical sectors with respect to the discoidal cell. I fail to see the importance of this character (viewed with regard to general homology), but the two species are so decidedly different from all others, both in markings and in anal structure, that the division is a natural one. Phryganea (Wallengr.).—The author seeks his characters in the same obscure region of the posterior-wings. According to my views, it heads a series of groups distinct from the preceding series, and individually is very marked in consequence of the anal parts of the @, especially the elongate superior appendages. The group is natural so far as applied to European species. Dasystegia (Wallengr.).—Again we have to deal with obscure characters as defined by Wallengren. In minute subdivision it appears to me that it includes two groups of equal value, one represented by varia, the other by obsoleta and Sahlbergqt. Trichostegia (Wallengr.).—A term used by Kolenati for the entire genus Phryganea (as usually restricted by modern authors), and, as I think, injudi- ciously applied to the most aberrant species, so strongly characterized by the neuration being alike in both sexes, and by the anal parts. Agrypnia (Wallengr.).—In carrying out his scheme of minute subdivsion, the author might have subdivided this into two, according to the neuration, especially of the posterior-wings of the ? , and also according to the appendages of the g. With regard to neuration, the condition seen in the arctic form of Pagetana (= var. hyperborea, McLach.) should not be lost sight of (¢f Supple- ment, p. xv). Agrypnetes (cf. foot-note, ante p. 2). Neuronia melanoptera. Oligostomis melanoptera, Wallengren, Entom. Tidskr., i, 68 (1880). “Wings blackish-fuscous: anterior-wings sparingly reticulated with orange spots, which are more or less confluent, punctiform in the disc: posterior-wings unicolorous. Legs yellow ; femora black, yellow at the apex.” (Translated from Wallengren.) Expanse, 26 mm. 4 First ADDITIONAL SUPPLEMENT. Sweden (Trolle Ljungby, 1 ¢). Not seen by me. According to Wallengren probably only a melanie variety of NV. clathrata, to which it appears to bear the same relationship that WV. S¢alii does to reticulata. Phryganea striata, p. 23, and Supplement, pp. i and xiti.—In July, 1882, Baron E. de Selys-Longchamps captured a pair(¢ 2) at a little lake close to the Simplon Hospice, Switzerland, about 6000 ft., certainly a very unusual altitude for this species; but Meyer-Diir (Mitth. schw. ent. Gesells., vi, p. 303) observes that Dr. Schoch found it on the Melchalp in numbers at an elevation of 6000 feet. These alpine examples are almost without dark markings on the wings, and in this respect resemble a form that predominates in some localities im Finland. An entirely obverse condition to this form occurs abundantly in the mountains of the Vosges (France) ; there the wings are nearly black, the pale markings being almost obliterated in the dark ground. Phryganea varia, p. 24.—Wallengren, in the paper previously alluded to, has acted on my identification of this with Ph. variegata, Fourcroy (ef. p. 25), and has restored the latter name. I have already pointed out that there was a “ Ph. variegata”’ prior to that of Fourcroy (but belonging to a very different modern genus), and think it inadvisable to unsettle established nomenclature, even if the use of Fourcroy’s name be justifiable, which I doubt. Phryganea obsoleta, p. 26, and Supplement, pp. 11 and xiv.—Very abun- dant in July on the margins of ponds and small lakes in the Vosges (Géradmer, &e., McLachlan). Agrypnia Pagetana, var. hyperborea, Supplement, pp. ii and xv.—lI think it advisable to bestow a distinctive name upon the dwarf high-northern form described at Supplement, p. ii, and noticed also at p. xv, and at p. Ixxxi (foot-note). Although, to my mind, there can be no doubt as to its being a condition of 4. Pagetana, the examples have so curious an appearance that, at first sight, the idea of their forming a distinct species would be quite pardonable. I have seen this form from Enontekis, in Finnish Lapland (J. Sahlberg), and from North-Western Siberia (Hautaika, Jenissei, J. Sahlberg, and Valley of the Ob, Bergroth). Fam. LIMNOPHILIDH. Glyphotelius punctato-lineatus and var. frigidus, pp. 41—43, and Sup- plement, p. v.—Livonia (common at the Peipus-See from the middle of May to the end of June, Max von zur Mihlen) ; most of the examples I have seen from this locality pertain to the var. frigidus, but the typical condition is also repre- sented, LIMNOPHILID2. 5 Limnophilus rhombicus, p. 48, and Supplement, p. xvii.—On August 12th, 1880, I found a ? example at the Statzer-See, near St. Moritz, Upper Engadine, Switzerland, at the great elevation of nearly 6000 ft. (cf Ent. Mo. Mag., xvii, p. 219). | A very singular example was taken by De Selys-Longchamps at a little lake close to the Simplon Hospice (about 6000 ft.),in July. The dark portions of the anterior-wings are very greatly pronounced, the only pale portions being the anterior margin and the two ordinary spaces. The example is a ?, and has the appendages perfectly linear (without any basal dilatation), but such a con- dition is not very unusual. Limnophilus subcentralis, p. 64, and Supplement, p. xviiii—Add Scot- land (Aviemore and Kinardochie, J. J. King ; Loch Awe, Cameron). Limnophilus decipiens, p. 53.—Add Livonia (Max von zur Miihlen). Limnophilus marmoratus, p. 54.—2 ¢ and 2 2 from Central Italy (Massa di Faitello, Apennino Pistojese, about 4600 ft., lst August, Haton) have the colours, &c., as in the var. nobilis (p. 55), and the form of the anal append- ages in both sexes shows divergence from the type-form to a rather serious extent, yet I dare not consider this divergence of specific importance. The most important differences are these:—In the ¢ the superior appendages appear to be narrower, the inturned apical margin with stronger teeth, and there are two very strong teeth at the lower angle of this margin (usually one only, sometimes divided into two smaller, in the type-form). In the ? the appendages are longer, the apices more produced, longer than the tubular piece (usually shorter than it in the type-form). Limnophilus flavo-spinosus, p. 59.—Add Italy (Massa di Faitello, A pen- nino Pistojese, about 4600 ft., lst August, Haton, 2 g; Pescia, Desideri, several examples in the Florence Museum). Limnophilus correptus, Supplement, p. xvili.—I possess a ? of this from Japan (Hakodaté, 24th September, G. Lewis). The ¢ remains unknown. Limnophilus lunatus, p. 61, and Supplement, pp. vi and xviiii—5 @ and 1 ? from Central Italy (Massa di Faitello, Apennino Pistojese, about 4600 ft., 1st August, Eaton) are of the rich yellow form already noticed from Carinthia, Asia Minor, &c. In two of them the pale fenestrate spot, anastomosal space, and lunate apical space, are scarcely indicated, and thus are nearly similar to the type of L. flavidus, Ramb., from Barcelona, which I have already united with lunatus. A ¢ from the Island of Sardinia (Costa) resembles the pale form in colour, but from the structure of the superior and intermediate appendages, I think it possible that it pertains to a new species ; more materials are necessary. 6 First ADDITIONAL SUPPLEMENT. Limnophilus germanus, p. 63, and Supplement, p. vii—Add to the lo- calities :—Switzerland (Altstetten, near Ziirich, Paul, 7th October). I have seen3 ¢ and 1 ? from the above-named locality. The males are of the usual size; one of them is a strongly-marked variety, in which the ptero- stigma in the anterior-wings is large and deep black, and the posterior have a distinct dark pterostigmatic spot, and the apex clouded with grey: the female expands to 33 mm., and has the anterior-wings almost uniformly fulvescent, with faintly darker pterostigma and only faint indication of the pale apical lunate space. Limnophilus submaculatus, p. 67, and Supplement, p. xix.—Occurs in the mountains of the Vosges (Géradmer and Retournemer, Cuny and McLach- lan). Limnophilus fuscinervis, p. 74, and Supplement, pp. vi and xx.—Add Livonia (very common, Max von zur Mihlen). Limnophilus nigriceps, p. 77, and Supplement, p. xxi.—Add Livonia (Dorpat and Oberpahlen, Max von zur Miihlen). Limnophilus picturatus, p. 78, and Supplement, p. xxii—Add Livonia (Maz von zur Mihlen), thus indicating a more southern distribution than ap- peared probable. The example seen by me is a very characteristically-marked 2, of large size (expanse, 25 mm.). River Kouda, N.W. Siberia (V. Sundmann, Lay): Limnophilus centralis, p. 79, var. italicus (n. sp. ?).—From Central Italy (Lago Nero, Apennino Pistojese, 5530 ft., 2nd August, Haton) I have 2 g and 38 9 altogether resembling ZL. centralis in general characters ; but in the &$ the apex of the inferior appendages is nearly furcate if viewed laterally, and excavated if viewed in front, and the apices of the opposing appendages are not pressed together as is apparently invariably the case in dried specimens of centralis ; moreover, the tips of the intermediate appendages appear to be turned downward instead of upward. I am much inclined to think these represent a good and distinct species, but have adopted the more cautious course of considering them only a variety, pending examination of further examples from the same locality, or from other parts of Central and Southern Italy. PLATE I,—Fig. 1, apex of abdomen of ¢, above; 2, same from side; 3, apex of an inferior appendage from side (more enlarged) ; 4, same in front (ditto). Limnophilus despectus, p. 90, and Supplement, pp. vii and xxii.—Add Livonia (not rare, Max von zur Mihlen) ; also Switzerland (Statzer-See and Val Bevers, Upper Engadine, Augt., about 6000 ft., McLachlan, 2 2, cf. Ent. Mo. Mag., xvii, p. 219; this is an additional example of the affinity of the alpine and boreal faunz). LIMNOPHILID2®. Z Limnophilus diphyes, Supplement, p. xxiiii—Add Finland (Jaakkima, J. Sahlberg, rather common) ; therefore the species forms part of the Fauna of Europe proper ; the examples do not vary from those found in Siberia. Anabolia nervosa, var. excisa. A. excisa, Hag., Verh. zool.-bot. Gesell. Wien, 1864, 803 (not described) ; ef: McLach., Revision and Synopsis, Suppl., viii. Dr. Hagen previously informed me that he thought the specimen from “ France,’ on which this name was bestowed, might be only a g¢ nervosa with malformed appendages. He has since kindly forwarded the specimen. 1 think it is not distinct from nervosa, but the appendages do not appear to me to be malformed, and it perhaps represents a local form not otherwise known. The principal character lies in the superior appendages, which have a distinct ea- cised apical edge, immediately below which the lower edge is very deeply excised (see the figure). PLATE 1I.—Fig. 1, apex of abdomen of ¢ from side. N.B.—The superior appendages of A. nervosa have a black tooth proceeding from an internal ridge close to the upper edge near the middle; but it is not always visible unless viewed from beneath. Anabolia nervosa, var. Putoni (x. sp. 7). A. sp.n., McLach., Revue d’ Entomologie, ii, 1884 (not described). My friend Dr. Puton gave me a pair (¢ 93) of an Anabolia taken by him near Remiremont, Vosges, France. They are of medium size, and rather pale in colour. The superior appendages of the ¢ are very peculiar in form (see figure), having a long straight (or slightly excised) apical edge, below which the lower edge is deeply and regularly excised. (The penis-sheaths and penis are much exserted in this individual, but probably accidentally). All the parts are symmetrical, and do not appear to be malformed. Either a very strongly- marked form of A. nervosa is here represented, or a new species. The small examples from Saxony (ef Rev. and Synops., p. 105) perhaps show a slight ap- proach to a similar formation. PLATE 1.—Fig. 1, apex of abdomen of ¢ from side (the intermediate appendages, penis-sheaths, &c., pur- posely omitted), N.B.—Very great caution should be exercised with regard to the species of Anabolia. Iam convinced that variation in the anal parts of the ¢ exists to a considerable extent, from local causes. Anisogamus difformis, p. 109.—A very large ¢ (expanse, 29 mm.) from North Italy (Tonale Pass, 5240 ft., 30th July, Haton) appears to belong here, as likewise do two ¢ from the Italian foot of Monte Rosa (above Macuguaga, 5300 ft., 15th July, McLachlan) that are still larger (expanse, 8303 mm.). A slightly smaller ¢ occurred in the Val Bedretto, Canton Ticino, on July 22nd (McLachlan). 8 First ADDITIONAL SUPPLEMENT. Acrophylax zerberus, p. 111, and Supplement, p. xxv.—Dr. Schoch sub- mitted to me examples in the Ztrich Museum, from Fliiela, Switzerland, very remarkable for their greatly abbreviated wings. Were it not that the amount of abbreviation varies in different individuals, this form would certainly be worthy of being distinguished by a distinct varietal name, and it occurs in both sexes. In one example the anterior-wings are about 11 mm. long, and, therefore, almost normal; in others the length varies from 6 to 9 mm., and in these the wings must have been nearly useless as organs of flight, though no particular abnormal condition of the neuration is observable, other than shortening of the apical cellules. 4. zerberus is especially an insect of great altitudes, and these individuals exemplify a tendency frequently seen in inhabitants of high moun- tains, or the high north. I have now no doubt that the very large examples mentioned at p. 112 are only individuals of the same species varying in just the opposite direction. Asynarchus ccenosus, p. 117, and Supplement, pp. ix and xxxi.—As the variation in this insect is due to local conditions, to some extent, it may be advisable to accept three principal varietal forms ; but they distinctly merge into each other. 1. ccenosus (Curt., type-form). The smallest condition; the anterior-wings shining greyish, ordinarily without paler or darker markings, save that the pale spot at the termination of the 7th apical sector is more or less indicated. This is the British form, occurring on elevated moors in the north of England and in Scotland. It has latterly become better known in Britain, and some examples from Clydesdale (KX. J. Morton) show traces of darker variation on the wings. 3 2. var. arcticus (Kol.). Ordinarily considerably larger, the anterior-wings apparently more pubescent, darker grey, less shining, and more or less varied with whitish. The ordinary form on the mountains of continental Europe. The size varies considerably (chiefly according to locality), and some individuals from Finland are scarcely to be distinguished, either in size or colour, from the type- form. 3. var. paludum (Kol.). Size as in var. 2, but equally liable to vary. Very dark, the an- terior-wings being nearly black in life with the ordinary pale (white or yellow) spots very conspicuous, and sometimes with pale freckles. The form from the Altvater Mountains; it also occurs, apparently exclu- sively, on the mountains of the Vosges, in France (Géradmer, McLachlan). A very distinct looking insect from the type-form, but, just as some examples of the latter show a tendency to approach var. 2, so do some individuals of var. 2 approach var. 3. : I am quite of the opinion that it will ultimately be possible to thoroughly connect the forms, both in size and colour ; indeed, this is almost possible now, from the materials in my own collection.

A 9? from the same place is in my collection. In the ? (dried) the 9th dorsal segment is very narrow (contracted under the 8th). Tubular piece formed superiorly of two nearly contiguous, slender, lanceolate, and acute testaceous valves, and a truncate obtuse hairy lower portion, which is one-half shorter. Side-pieces of 9th ventral segment obtusely conical. Vulvar-scale having a short, obtuse, thickened middle lobe ; side lobes distant, smaller, curved and sub-acute. No distinct ventral teeth. PLATE JI.—Fig. 1, apex of abdomen of 9, above; 2, same, from side; 3, vulvar-seale. Stenophylax crossotus (n. sp.). Body (including antenne, palpi, and legs) reddish-testaceous ; sides of mesonotum brownish or fuscescent ; hairs of head and pronotum reddish-testaceous ; spines of tibie and tarsi black. Anterior-wings long and narrow, very elongately parabolic at the apex, pale grey sprinkled with small whitish irrorations; the costal margin as far as the radius, and the sutural area, pale ; fenestrate spot and anastomosal space large and very distinct, whitish ; membrane slightly granu- lose, clothed with rather long adpressed greyish pubescence; costal margin in more than its basal half furnished with a dense fringe of rather long pale greyish (or whitish) silky hairs, each hair straight, but bent at its end and directed toward the apex: neuration pale, set with black hairs, which are long and strong on the post-costa and its branches; discoidal cell rather short, not so long as its footstalk, excised on its upper edge. Posterior-wings whitish, sub-opaque: neuration pale; discoidal cell long and narrow, the upper branch of the cubitus furcating almost on a level with its commencement (or very slightly beyond). In the ¢ the margin of the last dorsal segment is regular, very slightly inturned, the apex of the segment slightly scabrous and blackish, but having a median pale space. Superior ap- pendages concealed in the cavity of the segment, flattened, somewhat pyriform, with the inner edge excised. Intermediate appendages dilated at the base, but afterwards each forms a very strongly divergent, curved, piceous spine. Inferior appendages short, very broad, flattened, the apex truncate, thickened, and curved, so as to appear slightly excised. Penis-sheaths spini- form, testaceous. Penis short, slender, testaceous. A series of minute teeth on the 6th to 8th ventral segments, those on the 7th coarser and larger. 2 unknown. Length of body, 183—15 mm. Expanse, 41—45 mm. Corsica (2 ¢ from the Ziirich Museum, one of which was generously pre- sented to me). | Belongs to the typical group of S. corcentricus, but very distinct by the narrower anterior-wings (and their colour) in which the two ordinary pale 10 First ADDITIONAL SUPPLEMENT. spaces are very conspicuous ; and especially by the peculiar costal fringe of these wings, of which there are also indications in S. mucronatus; it is probably present only in the ¢. The anal parts are much concealed, but conform to the concentricus general type.

MESOPHYLAX. McLach., Journ. Linn. Soc., Zoology, xvi, 157 (1882), = Stenophylax, partim, olum. Very closely allied to Stenophylax typically ; differs especially in the spur of the anterior tibie of the ¢ being so much reduced as to have become micro- scopic, whereas, the corresponding spur in the ¢ is long; but the first joint of these tarsi in the ¢ is as long as in the 9. Palpi rather more slender. Prono- tum more developed. Median lobe of the vulvar-scale in 9 notched or bifid (so far as is known). These characters must be regarded as comparative only with the typical group of Stenophylaz. This genus was formed with the idea of easing the overweighted genus Stenophylax, influenced by the discovery of the virtually obsolete condition of the spur on the ¢ anterior tibiz in S. aspersus, and the further discovery that S. oblitus (in which I had already called attention to this peculiarity, vzde p. 116) is allied thereto, and will fall into the same genus. The species are as follows :— Mesophylax aspersus. Synonymy and bibliography at p. 182, add: JZ. aspersus, McLach., Journ. Linn. Soc., Zoology, xvi, 157. var. canariensis, McLach., loc. cit.

Canary Islands (hills beyond San Mateo, Grand Canary, 4550—4650 ft., 11th December, Eaton, 2 3). The size and locality render it possible that this may prove a distinct in- sular form ; but it is necessary to remark that I possess a typical ¢ from North Spain that expands to only 26 mm. | Notes on larve and cases that possibly belong to the Canarian form are to be found appended to those on the perfect insect at loc. cit. Mesophylax impunctatus (uz. sp.). Stenophylax aspersus, Meyer-Diir, Mitth. schw. ent. Gesell., vi, 8.9, nec Rbr. (noticed). Almost entirely agreeing with M. aspersus in form and size (the 9 sometimes very large ; 44 mm.), but much paler in colour. Body testaceous; the sides of the mesonotum usually fuscous or blackish. Antenne and legs yellowish. Anterior-wings pale greyish-testaceous, with scattered indistinct paler irrorations: neuration mostly reddish-testaceous (without dark spaces). Posterior-wings whitish: neuration pale. LIMNOPHILID®. tT} In the ¢ the anal parts are mostly as in aspersus, but with the following distinct differences. The inferior appendages are longer and much more slender (nearly straight, or scarcely genicu- late), and without any marked angular dilatation of the lower edge (which is always conspicuous in aspersus). Penis-sheaths with only one tooth before the prolonged apex. Switzerland (near Ziirich, apparently not uncommon, and in other locali- ties) ; Lago di Como; Bavaria. I have seen a ¢ from Scotland (Dumfriesshire, Service), and know not how to account for its presence there. ¢f King, Ent. Mo. Mag., xx, pp. 19, 20, in- dicated as JZ, aspersus, var. After a careful study, with more materials, I am convinced that this is specifically distinct from If. aspersus. The colour-differences are considerable, the insect being much paler, and without the alternate dark and light spaces on the neuration so conspicuous in aspersus (especially on the apical sectors). Moreover, there appear to be very sufficient structural differences in the anal parts of the ¢ (similar differences in the ? are not at present certain). It is probably not so decidedly a meridional insect as is JZ. aspersus. To it no doubt belongs the “ Stenophylax No. 7,” noticed by Hagen in Stett. Zeit., 1859, p. 133, from Bavaria (cf: Rev. and Synop., p. 183), and also the ? from Como referred to at Supplement, p. xxxiv. I have seen no example indicated. as having been found in a cave (a very common habitat with JZ. aspersus).

Mesophylax oblitus, To the bibliography given at p.115,add: WZ. oblitus, McLach., Journ. Linn. Soc., Zoology, xvi, 158. Micropterna Muehleni (2. sp.). Much resembling a small example of I. testacea, and of the same slender form. Body, antenne, palpi, and legs pale testaceous (the latter with black spines) ; side lobes of mesonotum blackish, and there is a blackish spot on each side of the metanotum. Basal joint of anterior tarsi of ¢ three-fourths the length of the second. Anterior-wings narrow, very pale greyish with a slight testaceous tinge, rather thickly sprinkled with indistinct small paler dots: neuration pale. Posterior-wings whitish, with pale neuration. In the g¢ the margin of the last dorsal segment is excised ; on each side of the middle is a patch of minute blackish sete, which are less numerous in the middle (somewhat as in HY. nyc- terobia) ; seen in front the margin is broadly inturned, with very sparse minute blackish sete. Superior appendages scarcely visible externally ; seen in front they are large, ear-shaped, concave and blackish (excepting in the centre). Intermediate appendages spiniform, stout, curved out- wards, dark reddish-testaceous. Inferior appendages not visible laterally; seen in front they occupy nearly the whole of the sides of the cavity of the segment, and each ends in a band- shaped obliquely truncate process, whereof the lower angle is slightly produced. Sheaths short, slender, spiniform, reddish-testaceous. Penis slightly shorter and more slender than the sheaths, straight and spiniform. No ventral teeth. 2 unknown. Length of body, 9 mm. Expanse, 28 mm, North Persia (1 ¢ in Max von zur Mihlen’s collection). ee First Appitr1onaL SUPPLEMENT. At first sight this is so like MZ. testacea that it might readily be confounded therewith ; but examination reveals different anal structure, and a remarkable diversity therefrom in the form of the first anterior tarsal joint in the ¢, which is even longer than in I. lateralis. If my abandoned genus “ Hemipterna” be ever resuscitated (cf. Supplement, p. xxxv, foot-note) this should find a place therein, rather than in Micropterna as represented by nycterobia and testacea. PLATE I.—Fig. 1, basal and second joints of anterior tarsi of ¢ ; 2, apex of abdomen of ¢, above; 3, same in front (in outline). Micropterna lateralis, p. 142, and Supplement, p. x.—I found the remains of a g in a spider’s web at the Lake of Géradmer, Vosges, France, agreeing more exactly with the usual British condition than does any individual I had previously seen from the Continent. Platyphylax Frauenfeldi, p. 143, and Supplement, p. xxxvi.—In the Ziirich Museum is a 9 from Naples that agrees sufficiently with the Austrian type in my collection ; it is larger (expanse, 48 mm.). I am still not in a posi- tion to form any decided opinion as to the distinctness of Frauenfeldi and pallescens, having seen no further materials of the latter. In the description of the posterior-wings of Frauenfeldi it would perhaps be more correct to say that the upper branch of the cubitus furcates on a level with (instead of “ slightly before’) the commencement of the discoidal cell. I have not yet seen the ¢ of Frauenfeldi, if pallescens be really distinct. At-present these insects appear to be of extreme rarity. Halesus radiatus, p. 148 (partim), and Supplement, p. xxxviiimExamples from Norway (Dovre, J. Sahlberg) appear to agree entirely (cf Suppl., p. Xxxvll) with others from Britain. Halesus digitatus, p. 150.—Certainly occurs in Switzerland. I founda g example in the Upper Engadine in August. Halesus ruficollis, p. 152, and Supplement, p. xxxyii—Common in the Upper Engadine, Switzerland, in August (MeLachlan) ; also France (Samoéns, Savoy, September, Haton). I have now.grave doubts as to the distinctness of H. mestus (p. 159), but do not refer it here as a synonym in the absence of males from the quarter in which the original type was found: possibly the var. melancholicus (p. 153) will prove to belong here. The examples from Savoy referred to mestus at Supplement, p. xxxix, are, I am now sure, identical with rujficollis. Halesus antennatus, p. 153, hilaris, p. 154, and uncatus, p. 155.—From Corsica (Damry) I have a pair (g ?) of an insect agreeing with antennatus and hilaris in colour, and more especially with antennatus (also in size), save in the colour of the antenne, which are not black. In the form of the second joint of the inferior appendages of the g it is nearer (without being altogether LIMNOPHILID #. 13 similar) to uncatus than to hilaris. This group of species evidently requires eareful study from abundant materials. I refrain from bestowing a name upon the Corsican insect. H. uncatus from Venetia (Belluno) is in the Florence Museum. Halesus ligonifer, p. 155.—From the Moselle at Remiremont, Vosges (Puton, end of October and beginning of November), I have before me 10 g and 3 2 of a species that I have no hesitation in identifying with H. ligonifer, MeLach., although the original ? type is no longer in my hands. The original description needs only slight modification. The anterior-wings are more or less clouded with greyish-brown (enclosing pale irrorations) in the apical and dorsal regions ; the two usual pale spaces large, much more strongly indicated in some individuals than in others. Tin the g the last dorsal segment is regular, its apical edge broadly testaceous. Appendages sunk in the cavity of the apex, excepting the inferior, and the penis and sheaths. Superior ap- pendages large, ear-shaped, concave internally, their outer edge regularly rounded and testaceous. Intermediate appendages concealed, apparently long and slender, arising from a basal piece, which has a large triangular tooth on either side, and a long and broad tongue-shaped plate in the middle below the appendages. Inferior appendages very prominent, upturned, testaceous, the apex obliquely truncate, so that the lower edge is shorter than the upper, fringed with long testaceous hairs; internally concave, and before the superior angle of the apex is a small lanceo- late tooth (the point of which is sometimes visible externally). Penis large and complicated ; the apex of the chitinous portion broad, each angle produced into a sharp piceous tooth; but extending along this broad apex, and apparently continued to the base above, is a more slender whitish membranous portion, notched at the apex; above, before the base, is a broad chitinous portion, separable from the other, but apparently articulated to it, each angle of which is pro- duced into a sharp piceous tooth. Penis-sheaths consisting of a stout cylindrical basal portion, at the apex of which are one or two small short spines, and three or four very long spines strongly curved at the tips. A few small teeth on the 6th and 7th ventral segments. In.the 2 the vulvar-scale perhaps consists of thick, broad, obtuse side-lobes, the middle lobe being apparently obsolete (not quite certain). Expanse, 34—38 mm. Although this species, by its coloration, seems allied to H. uncatus and hilaris, | think it is structurally nearer H. Melampus ; the inferior appendages want the second joint that is so characteristic of uncatus, &c., but the internal tooth possibly represents it in a rudimentary condition. It is evidently a late autumnal insect, like so many of its congeners.

Posterior-wings whitish-grey with dusky neuration ; pubescence blackish, almost microscopic: fringes darker grey and very short; discoidal cell as in the anterior; upper branch of cubitus furcating beyond the level of the commencement of the discoidal cell. In the 3g the last dorsal segment carries long golden hairs; its middle is scabrous and in- tensely black, this portion being dilated and somewhat produced anteriorly, and on either side of it is a marginal pale space. Superior appendages very small, testaceous, the outer edge broad and oblique, fringed with pale hairs. Intermediate appendages not separable if viewed from above ; black, straight, flattened and elongately triangular if viewed laterally. Inferior append- ages broad, incurved, very obtuse, inserted close together on the ventral margin, concave within, dusky testaceous, scabrous and black at the tips. Penis very slender, short, straight, yellowish, notched at the tip.

It should be noted that it is scarcely correct to say that Catadice has no “pouch” in the posterior-wings of the ¢ (cf Supplement, p. xl); there are in- dications of a very short pouch, but it has no pencil of hairs in it, and hence is scarcely evident.

These examples are of small size, and decidedly paler in colour when viewed in connection with a long series from the Alps, &e. Drusus trifidus, p. 171.—It would seem that occasionally (owing to mode of killing ?) the three projections of the margin of the last dorsal segment in the ¢ are liable to be turned under,.so that the margin appears to be truncate. This is distinctly noticeable in the majority of examples taken by me near Pontresina, Engadine, and to such an extent that it was some time before I could be convinced they did not represent a new species (especially as they are also of very small size) ; but in others, from the same locality, the usual trifid condition of the segment is indicated, but not strongly. I think this is only the mechanical result of drying, yet it is curious that all the examples from the locality do not show clearly the character whence the name of the species was derived. LIMNOPHILID®. 15 Monocentra improvisa (m. sp.). The & without “scales” on the wings, excepting in the “pouch”’ of the posterior pair. Black, with black hairs. Warts of pronotum (which are oval and very large) and wing- callosities reddish, with black hairs. Abdomen paler beneath. Antenne blackish-fuseous, the basal joint black. Palpi greyish-testaceous, fuscescent outwardly. Legs dingy testaceous ; coxe blackish ; femora fuscescent outwardly, excepting at the apex, which remains pale ; pos- terior tibie fuscescent outwardly in their apical half, excepting the extreme apex. Anterior- wings uniformly pale smoky-grey, slightly shining, and faintly olivaceous; membrane clothed with regular adpressed ordinary blackish pubescence: neuration greyish-testaceous, with strong black hairs at the extreme base, and on the lower cubitus and post-costa; discoidal cell about the length of its footstalk, rather broad: a short whitish line at thyridium and arculus. Pos- terior-wings pale fuliginous, occasionally with very faint pale irrorations in the costal portion ; pubescence of membrane slight, blackish ; a small whitish linear spot at the base of the 5th apical cell: neuration fuscescent ; discoidal cell longer than its footstalk, the upper branch of cubitus furcating on a level with its middle: these wings in the $ have a very deep pouch, ending considerably before the margin, in which are whitish waxy-looking scales, arranged in several series on either side, and directed outward. In the g the margin of the last dorsal segment has a large black roughened median space (with a pale space on either side), the apical margin of which is nearly truncate, slightly rolled inward. Superior appendages ovate, testaceous, varying in degree of exsertion. Intermediate appendages broad at the base and testaceous, afterwards narrowing, the tips turned upward, black and sub-truncate. Inferior appendages large and broad, nearly ovate, widely divergent, obtuse, concave above, up-turned if viewed laterally, testaceous with darker tips.

This interesting species has the size and facies of Drusus trifidus. It is a Monocentra to the extent that the pouch of the posterior-wings of the male is furnished with scales (of the same nature as in JL lepidoptera, but shorter, and the pouch does not extend so far towards the margin), but the membrane in both pairs of wings has only the ordinary pubescence. From the presence of “scales” on any portion of the wings I consider it a Monocentra; the anal parts are quite analogous to those of IL. lepidoptera and also to those of Drusus an- nulatus and Peltostomis sudetica and greca, the whole of which form a natural group on this character, although differing in spur-formule, and in the presence or absence of “scales.” PLATE I.—Fig. 1, pouch of posterior-wing of ¢, open, and very much enlarged; 2, “scales” in pouch, still more enlarged; 8, discoidal cell of anterior-wings; 4, last dorsal segment of ¢, above; 5, in- ferior appendage, and penis, above (in outline); 6, apex of abdomen of ¢, from side ; 7, same of 2, ubove; 8, same, from side. Chilostigma preteritum, Supplement, p. xlii.—I have seen numerous ex- amples of both sexes from Arctic Eastern Siberia, collected during the “ Vega”’ 16 First ADDITIONAL SUPPLEMENT. expedition in 1879 (Pitlekaj and vicinity, lat. 67° N., long. 173° W., July, Nordenskiold). These vary much in size (expanse, 19—25 mm.), irrespective of sex ; I subjoin further descriptive notes :— In both sexes the veinlet connecting the radius and sub-costa near the end of the latter in the anterior-wings is sometimes absent, or, at any rate, ill-defined. In the ? the anterior-wings are usually clouded with brown all over (with pale irrorations), but leaving a large, pale, irregu- larly quadrate, fenestrate spot, a smaller spot at the thyridium, and a more or less distinct and large anastomosal space. In the ¢ the part indicated as the “penis” (p. xliii) is really the lower penis-cover, which is whitish, and its apex forms two regular dilated lobes, separated by a small excision of the apical margin ; in this lie two shorter, slender, piceous, slightly curved sheaths, and the still shorter, slender penis, which is seldom visible. In the ? the 9th dorsal segment is small and narrow. Appendages in the form of two rather large, sub-contiguous, hairy, oval lobes, below which is a sub-quadrate horizontal plate. Vulvar-scale with broad thick side-lobes (no apparent middle lobe). No ventral teeth.

Sahlbergi, even in individuals from the same precise locality. In a very long series from the Vosges (Remiremont, Puton, beginning of November) the colour is darker than usual, in this respect approaching Ch. fusca.

Revue d’Entomologie, iii, p. 12). In the ? the 9th dorsal segment and the tubular piece are scarcely separable; the former apparently forming a broad triangle, the latter short, its outer edge oblique on either side, with a deep semicircular median excision leaving prominent lateral angles; beneath this is a cavity, and then succeeds a shining testaceous portion of the apical structure forming a nearly circular concave plate above, the edge of which is thickened and darker; below this again is an oblong piece of same texture and colour. Side-pieces of 9th ventral segment small, triangular at the apex. Vulvar-scale large, divided into two large, distant, thick, and obtuse side-lobes, and a very small and short triangular middle lobe. A few small teeth on the 6th and 7th ventral segments. Length of body, 9,11—113 mm. Expanse, 27—28 mm. Except in being slightly larger, with much longer abdomen, the ? does not differ in appearance from the ¢, and has the same elongate wings. The anal structure in the ? is somewhat aberrant.

SERICOSTOMATID.. 1 Enoicyla amcena, p. 208.—In the Ziirich Museum were three ¢ examples (one of which has been generously presented to me) of an Enoicyla from Switzerland (Biberbriicke, Canton Schwyz, 16th September, Paul) that appear to me to be undoubtedly HZ. amena. I subjoin a description :— Body black above ; pronotum, &c., scutellum of meso- and meta-nota, posterior margins of abdominal segments, and the terminal segment almost entirely, paler, reddish: hairs of head and pronotum black, sparse and rather long. Antenne blackish-fuscous, the basal joint dis- tinctly black. Palpi yellowish-testaceous; the apex of the terminal joint of maxillary pair scarcely darker; last joint of labial pair fuscescent. Legs yellowish-testaceous ; coxe black ; posterior tibis above, excepting at the base, fuscescent; tarsi (excepting the basal joint) fuscescent, the posterior distinctly black. Anterior-wings with broad rounded apices; very pale grey, membrane finely granulose under a lens, slightly clothed with yellowish pubescence : neuration rather fine, fuscescent, the apical sectors and anastomosis blacker, furnished with rather long black hairs; 5th apical cellule with a very short footstalk. Posterior-wings paler, with slight yellowish-grey pubescence and fringes: neuration fuscescent; all the apical cellules ex- tending to the anastomosis (in the examples before me). In the $ the margin of the last dorsal segment has a small rounded inturned flap in the middle, furnished with short black sete. Superior appendages scarcely visible, impressed and ear-shaped. Intermediate appendages in the form of long, lanceolate, acute, divergent, slightly curved testaceous blades. Inferior appendages forming broad flaps, the extremity of which is sometimes slightly produced (as in my figure) and slightly granulose, with dark hairs. Viewed in front the apical cavity is yellowish- or reddish-testaceous. 2 unknown. Length of body, ¢, 33—-4 mm. Expanse, 15—17 mm. » The above agrees in the main with Hagen’s brief description, which was no doubt taken from a rubbed individual. The only discrepancy is in the colour of the palpi, which is really not of much importance. I think that Hagen’s Enoicyla from Western Germany (pp. 208, 209) may be assumed to be identical with amena. In size, and general form and structure, amena is related to Coste, but the latter is paler, with more densely pubescent wings, and very different inferior appendages. | PLATE II.—Fig. 1, apex of abdomen of ¢, from side (the inferior appendages are not so much produced in the other examples, the apical portion being more inturned).

The indication of “Sections,” or divisions, by nwmerals, adopted in the ‘ Reyision and Synopsis,” is liable to inconvenience; I, therefore, propose to designate these according to the most typical genus in each, thus :— Section of SERICOSTOMA (= Section i, p. 222). i 3) SILO (=35 7% li, p. 239). - » BDRACHYCENTRUS (= ,, iii, p. 253). “ 3 WUEPIDOSTOMA,, “(== ,; iv, p. 270). 18 First ADDITIONAL SUPPLEMENT. | SERICOSTOMA, p. 223. Since the last Supplement was published (June, 1880), I have lost no opportunity of amassing materials for this genus during my excursions, and my friend the Rey. A. E. Eaton has aided me by doing the same in the course of his travels. On the other hand, some of the original materials are no longer available, having been returned to the various owners. I find it necessary to attempt a Revision of the entire genus. In one instance (personatum) two species were certainly confused by me, an idea foreshadowed at Supplement, p. xlvi. But I sink at least one form, as founded on conditions of no specific value, and others would probably go the same way had I sutlicient connecting materials before me. It appears to me that the species may be divided into two groups according to the amount of prominence of the maxillary palpi of the 8. This is an excel- lent character, and amongst the large mass of materials there are scarcely any individuals left in doubt as to their position from this point of view. The colour of the antenne is sometimes of secondary specific value, but it is a character that should be used with caution, for it is often vague, and may occasionally be due to local influences. Then, with regard to the anal parts. I have not succeeded in finding dif- ferences in the 9, but it is by no means improbable that such exist, a point to be solved from a comparison of living or alcoholic specimens. In the ¢ I have arrived at the conclusion that, as a rule, no characters exist of any importance, excepting in the penis-sheaths, and for their precise examination it is usually necessary to remove the inferior appendage on one side. Even in the penis- sheaths it is evident, when a large mass of materials is examined, that much variation exists in what may reasonably be considered one and the same species, sometimes irrespective of locality, at others apparently to some extent depending upon local influence. This is of great importance, because these sheaths are of a very hard chitinous nature, and little subject to alteration or distortion in drying. In giving a new arrangement of the species, according to my present views, it is necessary to state that all materials formerly examined by me, and returned, should undergo a re-examination by those to whom they belong.

Species bracketed together are closely allied, according to the penis- sheaths, and, in some cases, may not be distinct. N.B.—All the figures of the penis-sheaths are drawn to nearly the same scale. Sericostoma personatum, p. 226, and Supplement, p. xlvi (personatum, Spencii, Latreilliit, assimilis, and hyalina, of English authors; personatum, McLach., partim, olim; analis, Steph., 3, var; chrysocephala, Lett. ?). This is the only species that occurs in Britain; the northern examples are darker than the southern. Possibly it is the only species in Scandinavia and Finland. Of its precise southern limit I am uncertain, but it seems to me that I have never seen it further south than the Vosges (Géradmer, &c.), the other individuals formerly confused by me with it being forms of pedemontanum. It is extraordinarily variable in the form of the penis-sheaths as will be seen from the series figured, and I cannot decide that this is to any considerable extent dependent upon locality. As a rule, the upper branch is shorter than the lower, thicker, the upper apical edge oblique to the apex, and turned slightly downward (a notable exception is seen in fig. 8), sometimes with a distinct notch before the oblique apical edge (figs. 7, 8, and 9), rarely with the upper edge perfectly regular and gently curved (fig. 6).

In connection with personatum I give figures from isolated forms (single specimens) that I cannot satisfactorily place anywhere. They appear to have the palpi of Group A, but rather less prominently, and these parts are also more hairy. Fig. 11, Ronquiéres, Belgium ; 12, Nolay, France.

I omitted to notice the condition of the palpi when the typé was in my hands. Here should, perhaps, be referred a small series of examples from the Vosges (Géradmer, &ec., July, McLachlan), in which the antenne are annulate (but indistinctly), and in which the penis-sheaths agree tolerably well with my figure of that of the type.

Sericostoma Schneideri, p. 230.—No further materials have come to hand; doubtfully distinct from flavicorne. I now incline to refer here the example from “St. Aubin,” alluded to at Supplement, p. xlvii, under ¢imduwm, and think my lamented friend Prof. de Rougement was, perhaps, mistaken as to the locality, and that it probably was captured by him during his tour in Southern Italy. PLATE I1.—Fig. 1, Ragusa; 2, “St. Aubin?” Sericostoma Selysi, p. 231.—No further information. It evidently be- longs to Group A, according to E. Pictet’s figure of the head on pl. xi, fig. 3 (compare his figure of the head of S. beticum, pl. ix, fig. 3). Sericostoma faciale, p. 233.—I have seen no further examples. Meyer- Diir (Mitth. schw. ent. Gesell., vi, p. 316) refers another example here. One of the most distinct species, according to the extraordinary form of the penis-sheaths. It is quite possible that the condition of the palpi was owing to distortion, for I see indications of a similar condition in individuals of other species. PLATE II.-—Fig. 1, from type. Sericostoma siculum, p. 232.—Of this Sicilian species I have no further information, and do not possess it. It should be one of the most distinct. PLATE I.—Fig. 1, from type.

It should belong to Group A, from my words, “maxillary palpi of the ¢ very prominent.” Sericostoma pedemontanum, p. 229 ( personatum, McLach., olim, partim; personatum, Meyer-Diir, Rostock, ?, &ce ; collare, Pict., Brauer, Meyer-Dir, olim, &c. ; memorabile, McLach. ; multiguttatum, Pict., 2, var.). This commences Group B, and it may conveniently head that Group, because the maxillary palpi although less prominent than in Group A, are more so than in most of the other members of it, in some of which these palpi scarcely project beyond the face. SERICOSTOMATID 2. 4 | I have already stated that my former personatum was in part made up of materials that I now consider to belong here, and my fig. 12 (Pl. xxv) should be referred here. Regarding all the materials (200—300 examples) before me as pertaining to one species, this is one of the most common insects in all the more hilly dis- tricts from Northern Central Europe to Central Italy, but I have not seen it (with certainty) from the Pyrenees and the Iberian Peninsula. I adopt the name pedemontanum, there being no other available, excepting multiguttatum, Pict., which would be extremely misleading, being founded on a common condition of the ? only, a precisely parallel condition occurring in the ? of almost all the other species. The materials before me have had long and careful study, and I think that when the figures of the penis-sheaths are examined, most students of these insects will agree that no course other than that here adopted was open to me. In the typical example, from Turin, the upper branch of the sheaths is con- siderably longer than the lower, and quite simple (see fig. 2) ; other examples - from Central Italy (Apennino Pistojese, Haton) mostly agree therewith. But there appears to me to exist every conceivable modification between this form and the other extreme (see figs. 14, 15). Then again with respect to S. memorabile (see fig. 10), which, in the type, was apparently distinguishable by a projection on the lower edge of the upper branch before the apex, followed by an excision. Almost every possible gra- dation exists between the typical memorabile and the. condition in which the upper branch is absolutely simple. (A very singular condition exists in an example from the St. Gothard, taken with ordinary forms, in which there is an absolute tooth below the apex [see fig. 11]}). A long series of examples from the borders of North Italy and South Tirol (Val Camonica, Val Mazza, Tonale Pass, &c., Haton) differ so much from the ordinary range of variation, and seem so far constant in the different indivi- duals, that I doubt whether they ought not to be designated by at least a varietal term. In these the branches of the fork of the penis-sheaths are very short, simple, and the upper branch not infrequently shorter than the lower. In addition to this, the ventral triangle is ordinarily clear yellow, and its apex remarkably produced and acute. In former times I should have considered them distinct, but having in view the extreme variability now proved (I think) to exist in the “species” taken as a whole, I place them (at least provisionally) with pedemontanum (see figs. 20, 21, 22).

Ac- cording to its sharply annulate antenne, and the form of the penis-sheaths, it should be quite distinct. PLATE IJ.—Fig. 1, from type. Pi First ADDITIONAL SUPPLEMENT. Sericostoma clypeatum, p. 233.—This Corsican species is one of the most distinct. I have an additional example (Porto Vecchio, Reveliere, 19th April). 7 PLATE II.—Fig. 1, Corsica.

Maxillary palpi of ¢ slightly pro- minent, clothed with fuscous or golden-brown hairs. I would much have liked to compare alcoholic specimens of H. sperata with this insect, more especially as my figures of the inferior appendages given for that species may not represent their true form; but there appear to be other structural differences sufficient for specific separation. PLATE III.—Fig. 1, head of 3, above; 2, apex of abdomen of 6, above ; 3, same, from side; 4, same, beneath (all these outline figures are from examples in alcohol). Also from Portugal (neighbourhood of Cea, Beira Baixa, 5th and 11th June, Haton) I have 2 9 (dry) of Helicopsyche that I hesitate to unite with /7. lusitanica, on account of their much smaller size (the 9 is usually the larger in this genus); they are much rubbed, but appear to have been much paler originally than H. sperata. I do not detect any ventral tooth in these speci- mens. N.B.—In connection with the occurrence of this genus in Portugal, the eases in the British Museum from near Oporto (cf p. 268) should not be forgotten. Helicopsyche Revelieri (x. sp.). Case :—H. Shuttleworthii (for bibliography, ¢f. p. 267). Head of g, above, with two large tufts of sub-erect golden-yellow (mixed with blackish behind) hairs, placed on the posterior portion of each pyriform wart; a double tuft of pale yellow silky hairs on the face curved up between the antenne. Palpi clothed with golden-yellow. Antenne fuscous, rather indistinctly annulated with testaceous; basal joint with yellow hairs (in the g the clothing of the head is sparse, not arranged in tufts, and darker). Legs silky yellowish ; tibise and tarsi externally (especially of the posterior legs) fuscescent. Thorax and abdomen blackish ; anal parts yellow. Anterior-wings narrower than in H. sperata (especially narrower in the g), very densely clothed with golden-brown adpressed pubescence, in which a slight oblique line in the apical portion in the g, formed of more thickened blackish hairs, is often visible; fringes long, fuscous: neuration apparently not differing in arrangement from that of H. sperata. Posterior-wings blackish-brown, with concolorous fringes. In the g (dried) the anal parts are arranged after the same plan as in the other European species. The most noticeable difference from the preceding species is that the inferior appendages have no basal process (or branch), but the ventral angle in these appendages is somewhat pro- duced. Superior appendages very small (only just visible in dry examples). Minute details of the anal parts should be made from examples in alcohol. In the ? (dried) the anal parts are formed generally after the plan seen in H. sperata. Expanse, 8—9 mm.; the ? usually the larger.

All from dried specimens. My generous correspondent, M. Reyeliére, furnished me with most abundant materials for this species, both of imagos and also of cases, a portion of which were in alcohol. Inability on my part to attend to the alcoholic specimens at once, resulted in the spirit evaporating, so that I cannot now give such minute structural details and figures as otherwise might have been obtained. 30 First ADDITIONAL SUPPLEMENT. The small size of the creature, the pale yellow clothing of the head, the golden-brown pubescence of the anterior. wings, the anal structnre of the J, &c., all prove this to be abundantly distinct from H. sperata. The same reasons that have induced me to set aside the specific name agglu- tinans as applied to the case of H. sperata, cause me to set aside that of Shuttle- worthii as applied to the case of Reveliert, and, in adopting this latter term, I carry out the wishes of my late friend de Rougemont, who intended to thus designate the insect in a paper he had in preparation before his long illness and premature death. M. Reveliére had furnished Prof. de Rougemont with extremely detailed information concerning the insect, which he bred in great quantity. This information is now not available. But he also, in his letters, imparted a portion of it to me, and I think some extracts will be useful: He found the larve in very great abundance in a shallow stream near Porto Vecchio, and, according to his observations, the imago probably continues to appear nearly all the year round in that southern locality, but it seems to require a certain degree of warmth, and its emergence from the case is always effected in the day-time. The larve and pupe can exist with only a very slight amount of moisture; as a proof of this, a number of larve placed by him in a vessel with sand and water were neglected during a period of three weeks, owing to illness; at the end of that time the water had evaporated, leaving the sand uncovered, but moist, and the larve were still alive. I have 200—800 cases before me from Porto Vecchio. They vary much in size—24 to 45 mm. in diameter ; each case forms fully two and a half whorls. The building material is fine sand-grains, and in the two upper whorls, and fre- quently in part of the lower whorl, the colour is blackish, and the individual sand-grains appear to be cemented together, or covered, by some matter that renders difficult the discrimination of single grains. But the mouth-end of the lower whorl is invariably composed of pale sand-grains, even in the smallest (and presumably youngest) cases, proving apparently that the black colour of the older portion of each case is due to some sedimentary deposit. In addition to the above-mentioned cases, M. Reveliére forwarded about 40 found by him in 1860 under stones in torrents at Monte Renoso, above Bastelica. These vary in size as in those from Porto Vecchio, but the sand- grains of which they are composed remain pale in all portions of each case, due probably to the condition of the water the larve inhabited. For my part I consider it most probable that the cases from Porto Vecchio and Monte Renoso belong to the same insect. But the subject assumes a cer- tain amount of significance, because M. Reveliére suggested (an one of’ his letters) that as the original cases found by Blauner in Corsica were from the mountains, those from Monte Renoso are probably identical with Shuttleworthit, supposing the insects frequenting the two localities to be distinct. The case from the Lago di Como, mentioned in connection with H. Shuttle- worthii, more probably is to be referred to H. agglutinans, and therefore to H. sperata. SERICOSTOMATID®. Ba Lepidostoma hirtum, p. 274, and Supplement, p. Ixiii—The description of the structure of the inferior appendages of the ¢ at p. 275 is not sufficiently precise ; add the following: inserted in the concave inner-side of each append- age, a little below the apex, is a small obtuse process or supplementary Joint, visible both above and beneath; at the inner edge of the base (connected therewith ?) of each appendage, viewed ventrally, is a straight slender process. PLATE II.— Fig. 1, inferior appendage of ¢, from beneath, Lepidostoma fimbriatum, p. 276.—A ¢ from Portugal (slopes of Foia, near Monchique, Algarve, about 2800 ft., 21st May, Haton) agrees with the description of the type (which is not now before me) ; it expands to 155 mm. From it I make the following additional notes :— The fringe of long clavate hairs turned downward, at the base of the costa of anterior- wings, is less extended than in Z. hirtum, and yellowish instead of black ; the few “scales’’ on these wings are nearly confined to the nervures. On the posterior-wings the “scales” are more numerous, and sparsely scattered over the membrane as well as on the nervures. The anal parts are quite analogous to those of L. hirtum; probably the spiniform interme- diate appendages are more slender and sinuous ; all the hairs are yellow. A 2? from Portugal (streamlet near Villa Real, Traz-os-Montes, 1280 ft., 25th June, Haton) probably belongs here: it expands to 18 mm., and does not apparently differ in structure or colour from the same sex of L. hirtum. I think Z. fimbriatum may be regarded as specifically distinct, but the only very tangible differences from Aértwum, in the g, are the paler colour, and the very sparse clothing of “scales” on the anterior-wings. PLATE II,—Fig. 1, intermediate appendages of ¢, above. Dinarthrum pugnax, p. 279.—Additional materials from Ala Tau (3 2, 2 2, received from Staudinger), in better condition than the original types, enable me to give amended descriptions and figures of the anal parts. In the g the 9th dorsal segment forms a broad plate, the apical edge of which is almost rounded, whereas the sides slope outward, so that it forms a kind of broad triangle with very obtuse apex. From beneath either side of this plate proceeds a large triangular piece, slightly ciliated on the margins (these may be considered superior appendages). From beneath the apex of the plate, viewed from above, proceeds what looks like a double plate, the divisions of which are (usually) separated by a notch, and the sides of which are directed nearly vertically down- ward if viewed from the side; but seen from beneath it is tolerably evident that this apparently double plate represents the intermediate appendages, forming two broad, ciliated, slightly diver- gent apical pieces, proceeding from a broad concave basal part in the cavity of the apex. In- ferior appendages very long, directed strongly upward, lanceolate, and acute, with a strong fringe of hairs on the lower edge ; within the apex of each is attached a kind of sub-apical second joint, which is flattened and semi-transparent, and broadly truncate at its apex (this is the homologue of the process in Lepidostoma noticed above). ‘The penis and sheaths can be seen from beneath ; the penis is short and very slender, notched at the apex, turned somewhat to the right ; it is accompanied by a pair of longer sheaths, also turned to the right; whereof the left- hand one is slender and spiniform, and the right-hand one is broader, flattened, somewhat suddenly acuminate, and very acute at the apex. In the ? the 9th dorsal segment forms a plate with very obtuse apical edge, from beneath which projects a bifid (if viewed from above) plate, very concave beneath. Ventrally there appears to be a broad vulvar-scale, slightly acuminate at its apex.

Fam. LEPTOCERIDA. The transference of Berea and allies to this Family (cf Supplement, p. lviii), renders invalid the indication of “Sections” by numerals. I therefore propose the scheme noticed below, which is the more advisable because there may probabiy exist exotic species of the Family that will not fall within the limits of any of the “ European’ Sections; and the latter remark applies equally to other Families. Section of BeRmA (= Section iv of Rhyacophilide, p. 490). » 3, MOLANNA ( “not petiolate” in montanus, and at p. 383 1 said that it 1s “ rarely petiolate. I find, however, that in some localities, this fork is usually shortly petiolate : sometimes this condition is correlated with striking differences in coloration, sometimes not. In many specimens from France (Auvergne) the fork is pe- tiolate, and it is often so in others from the French Pyrenees. Finland (Jaakkima, J. Sahlberg) : in the only specimen I have seen, fork No. 4 is shortly petiolate ; it is typical otherwise. From Portugal (Villa Real, Haton) I have four examples that scarcely differ from the type-form, save that the dark ground of the anterior-wings is reddish-brown rather than fuscous: in one-of these the apical fork No. 4 reaches the anastomosis, in the others it has a more or less long footstalk. These appear to be quite distinct from the examples from the same locality described above as Ph. perversus. Philopotamus montanus, var. cesareus. Antenne sharply annulate, fuscous and yeliow. Legs pale yellow. Anterior-wings pale golden-yellow, reticulated and spotted with greyish-fuscous, a spot at the arculus being larger and more distinct: apical fork No. 4 reaching the anastomosis. Posterior-wings very pale grey, with conspicuous golden-yellow spots round the apical margin. Expanse, 18—20 mm. Island of Jersey (W. A. Luff, 3 8,2 9). This form was alluded to at Supplement, p. Ixxi. From its insular habitat and general appearance it appears worthy of a varietal name, for although some specimens from the mainland of Britain show an approach to it, I have not, with one exception, seen any that tolerably agree therewith. The one exception is a ¢ from Clydesdale (K. J. Morton); itis slightly larger and the neuration of the posterior-wings is darker. In bestowing a varietal name on this insect, a doubt may rightly be raised as to whether Ph. insularis from the neighbouring Island of Guernsey be en- titled to rank as more than a variety of montanus. Possibly it should not be so entitled ; nevertheless, the anterior-wings seem more decidedly long-oval in form (if this be not an illusion), and their colour is dull golden-yellow, with the dark markings much more obliterated. Philopotamus montanus, var. chrysopterus. Ph. montanus, var. chrysopterus, Morton, Ent. Mo. Mag., xx, 273 (1884). Very similar to the var. cesareus. Anterior-wings bright golden-yellow with grey reticula- tions and fuscous spots, the latter few in number and arranged almost as in Ph. insularis: apical fork No. 4 with a footstalk. Posterior-wings very pale grey, nearly their apical half clothed with goldenzyellow pubescence, in which are pale grey reticulations ; fringes golden-yellow: neu- ration blackish, each apical sector, &c., with a small black spot at its termination in the margin, which spots are continued into the fringes, and intersect them. Expanse, 18—19 mm. Scotland (on the side of a hill termed “ Tinto,’ nearly 2000 ft., near Car- luke in Clydesdale, K. J. Morton, 3 2). 48 First ADDITIONAL SUPPLEMENT. A very pretty and interesting form. The anterior-wings are marked almost precisely as in Ph. insularis, but they appear to be broader, and their ground colour is bright golden ; moreover, apical fork No. 4 extends to the anastomosis in iasularis. The golden pubescence on the apical portion of the posterior- wings is very remarkable, and in this it approaches the Corsican Ph. flavidus. It is singular that so bright a condition should come from so far north. Mr. Morton does not find the typical form*of montanus in the locality, and the individual alluded to above, under var. cesareus, was, he believes, taken at a low elevation. In taking leave of Ph. montanus for the present, it may be well to state that all the forms have been examined with regard to the inner anal parts of the ¢, without the discovery of appreciable differences. N.B.—I can add nothing further concerning Ph. siculus (p. 885), and it is necessary to see examples in good condition in order to establish its claim to specific right. Philopotamus amphilectus (n. sp.). Head and pronotum clothed with very bright golden-yellow hairs. Antenne uniformly dark brown. Palpi brown. Legs dingy brownish-testaceous (the posterior paler) ; anterior and intermediate femora fuscescent in certain lights; spurs dark brown. Anterior-wings rather broad; clothed with rich golden pubescence, in which are reticulations and large spots of blackish- fuscous, especially round the apical margin (but the amount of spotting and reticulation varies greatly) ; apical fork No. 4 with a footstalk varying in length: fringes golden, intersected with blackish-fuscous. Posterior-wings smoky-blackish, with darker neuration: a series of golden- yellow spots round the apical margin, sometimes confluent and reticulated with grey. In the ¢ the external anal parts proportioned almost precisely as in montanus (the superior appendages, perhaps, larger and broader): inner parts more as in variegatus, totally yellow ; upper penis-cover very obtuse and turned upward if viewed laterally ; penis (?) broad, pro- duced into a fine point, concave beneath ; sheaths very slender, flattened-spiniform, very acute and slightly up-turned at the tips. Expanse, 22—27 mm. Mountains of the Estrella, Portugal (near Cea, 1792 ft., 4th June, 5 2, and near Sabugueiro, 4100 ft., 5th June, 1 ¢, Beira Baixa; Haton). A large and very handsome species, agreeing with montanus in the form of the external anal parts, and practically with varzegatus in the inner anal parts, but seemingly quite distinct from both: agreeing also with variegatus in the unicolorous antenne, but these are brown instead of yellow. The amount of dark reticulation and spotting on the anterior-wings varies very much ; in some specimens it is nearly as much reduced as in znsularis and flavidus, in others it approaches the normal condition of montanus. PLATE YV.—Fig. 1, apex of abdomen of 6, from side; 2, upper penis-cover, &c., from side, more enlarged. Var. Antenne pale brown, indistinctly annulate with darker. Anterior-wings blackish- fuscous, thickly irrorated with small golden-yellow spots (almost as in normal montanus and. ludificatus): apical fork No. 4 scarcely petiolate. Posterior-wings having the apical marginal spots nearly obsolete, and almost confined to the fringes. External and inner anal parts as in the others.

Legs fuscous, with a slight testaceous tinge. In the g the margin of the last dorsal segment is regularly and shallowly excised. Superior appendages very long, dilated at the base, but gradually arcuate and acuminate if viewed laterally. Upper penis-cover lanceolate, extending to between the apices of the inferior appendages, its apex slightly upturned. Inferior appendages skort and broad, the second joint scarcely nar- rower than the first, only very slightly longer than broad, its apex very obtuse. In the @ the apex of the abdomen presents no special (other than generic) peculiarities. Size of D. pullus, or slightly smaller. Portugal (near Sio Romio, Cea, Beira Baixa, 1792 ft., 9th June, Katon, Teale) Allied to D. pullus by the dark coloration, which is intensified: differs in the anal parts of the @, especially in the form of the margin of the last dorsal segment, and in the very short and broad second joint of the inferior appendages. PLATE V.—Fig.1, apex of abdomen of 6, from side. Wormaldia triangulifera, p. 390, and Supplement, p. lxxii.—lI refer here examples from the following localities, all of which appear to present an amount of excision of the last dorsal segment in the ¢ sufficient to separate them from occipitalis : North Italy (Val Anzasca, in July, common, McLachlan and Haton) ; Cen- tral Italy (Apennino Pistojese, various localities, July, Haton). Wormaldia mediana, p. 391.—I refer here examples from the following localities : Central Italy (Apennino Pistojese, in July, Eaton). The examples are dark, but do not appear to haye the same form of wing as subnigra. 50 Frrst ADDITIONAL SUPPLEMENT. North Italy (Val Anzasea and its lateral valleys, very common in July, McLachlan and Eaton). The same remark as to colour and form applies to these. Portugal (Cea and Ponte de Morcellos, Beira Baixa, 11th and 14th June ; Villa Real, Traz-os-Montes, 22nd June; Haton, 8 examples). Some of these (especially those from Villa Real) are very dark, still they do not appear to me to be identical with subnigra ; the amount of excision of the last dorsal segment in the ¢ varies. N.B.—Also from Portugal (near Villa Real, and near Salamonde, 24th and 30th June, Eaton) I have 2 ¢ that remain very doubtful. They agree with occipitalis in size and colour, and in the unexcised margin of the last dorsal segment, but the inferior appendages seem to be formed as in mediana and sub- nigra. The specific characters in this genus are slight, and not always easy to selze. Plectrocnemia geniculata, p. 396, and Supplement, p. Ixxii.—Add: North Italy (Val Anzasca, 18th July, MeLachlan,1 3). Plectrocnemia inflata (2. sp.). Reddish-testaceous (or ferruginous). Head and pronotum above clothed with dense reddish- yellow hairs in the middle, which become black on the sides and on the wing callosities. An- tennee yellow, with the faintest indications of darker annulations. Palpi and legs yellow; spurs reddish. Anterior-wings densely irrorated with more or less confluent yellow spots (with a ferruginous tinge), in which the ordinary dark markings are blackish-fuscous (the membrane, without the pubescence, is pale grey); fringes reddish-yellow. Posterior-wings pale grey, with grey fringes, which are slightly yellow in the apical portion. In the g the upper penis-cover is short; above it appears as two triangular points pro- jecting from beneath, a shorter membranous plate. Superior appendages small and triangular, fringed with long hairs. Intermediate appendages (?) small, nearly conical with truncate apex. Beneath the upper cover are probably a pair of short penis-sheaths, which have the appearance * of being sinuate on their lower edge. Inferior appendages very large, hairy, inserted somewhat distantly on the ventral margin; the basal portion very broad, deeply concave within, which gives it an inflated appearance ; the apical portion slender, turned very strongly inward in an almost geniculate manner, very slightly dilated beyond the constriction. At the base of the upper edge of these appendages, viewed laterally, is a slender, slightly-curved supplementary appendage, gradually widened from apex to base. All the anal parts are yellow. 2 unknown. Length of body, 7 mm. LExpanse, 22 mm. Portugal (stream westward of Villa Real, Traz-os-Montes, 1280 ft., 24th June, Haton, 1 ¢). In the structure of the inferior appendages this is allied to P. geniculata, but even these differ in the basal portion being more inflated, the apical portion shorter, and the whole less suddenly geniculate ; the other anal parts differ con- siderably from those of geniculata, and the bright (almost ferruginous) general coloration of the wings and body is very distinct therefrom. (N.B.—It may be that the inferior appendages of geniculata are not truly bi-articulate ; in inflata I detect no suture at the constriction before the slender apical portion). PLATE V.—Fig. 1, apex of abdomen of ¢, above; 2, same, from side; 3, an inferior appendage, beneath (slightly less enlarged). HYDROPSYCHID®. 51 Plectrocnemia prestans (2. sp.). Black. ~Head and pronotum clothed with golden-yellow hairs, becoming blackish on the sides and on the face. Antenne yellow, faintly annulate. Palpi fuscescent, pale at the articula- tions. Legs yellow. Anterior-wings grey, densely irrorated with small rounded golden-grey spots, and almost without darker markings, excepting a few blackish-fuscous indications in the pterostigmatic region: neuration dark fuscous: fringes grey. Posterior-wings smoky-grey, with fuscescent neuration and grey fringes. é unknown. In the 9 the appendages of the 8th ventral segment are transverse, each produced into a point internally, the upper edge nearly straight, the outer edge very oblique. Length of body, 9,8} mm. Expanse, 29} mm. North Italy (near Bannio, Val Anzasca, 22nd July, Eaton, 1 3). Ordinarily it would be very imprudent to describe a Plectrocnemia from the ? only, but the form of the appendages of the Sth ventral segment is so utterly different from that of any other species of which this sex is known, that I do not hesitate to describe this individual. Moreover, the very large size renders improbable its connection with any species of which the ? is unknown. From its size, colour, and markings, it. might readily be mistaken for Rhyaco- phila proxima. PLATE V.—Fig. 1, apex of abdomen of ¢, beneath, Plectrocnemia conspersa, p. 394, and Supplement, p. lxxii—Add: Bel- gium (near Dinant, 14th July, McLachlan, 1 2 ; Switzerland (near St. Moritz, Engadine, 6000 ft., August, WeLachlan, 1 8). Plectrocnemia conspersa, var. breviuscula. _ Probably presenting no tangible differences from the type, excepting in the inferior appen- dages of the ¢, which are distinctly shorter, with their apices less produced, more regular in outline, and less attenuated. North Italy (Lago di Silissi, Val Mazza, Lombard Alps, 5500 ft., 29th July, Eaton, 5 8,4 9.; Macugnaga at the head of the Val Anzasca, over 5000 ft., 14th July, WMeLachlan, 1 6,2 2). I have long hesitated between describing these individuals as a new species and uniting them with conspersa. I adopt the middle course by considering them provisionally a variety of the latter. The distinctness is not notable ; yet, in regarding a long series, the shortness of the inferior appendages of the ¢ is evident, and apparently constant; and it is not the shortness only, for the tips of these appendages seem to differ in outline. PLATE V.—Fig. 1, inferior appendage, in outline, beneath ; 2, same, from side, more enlarged (Figs. 3 and 4, the same of conspersa-type, for comparison, drawn to the same scale). Plectrocnemia brevis, p. 396.—It appears to me probable that the ex- ample (¢) from Bergiin (¢f p. 397) is perhaps distinct from brevis, which would thus be limited to the types from Sedrun. A second ¢, from the Pyre- nees (without indication of the precise locality), is probably specifically identical with that from Bergiin. Possibly we have here the representatives of a new U. f ILL UR ~ 52 First ADDITIONAL SUPPLEMENT. species intermediate between brevis and scruposa, differing from the former in the much less prominent and shorter penis (or penis-cover?), and from the latter in the unexcised apices of the inferior appendages. I do not think it prudent to decide at present. Plectrocnemia letabilis, Supplement, p. Ixxii1.—Add: Portugal (near Villa Real, Traz-os-Montes, 22nd June, Eaton, 1 ¢). The markings of the anterior-wings are rather more pronounced than in the Pyreneean types, in con- sequence of the ground-colour being darker (blackish-fuscous instead of sreyish-fuscous). Plectrocnemia appennina (7. sp.). Fuscescent ; pronotum, metanotum, and base of abdomen above inclining to reddish ; under- side yellowish. Head and pronotum with reddish-golden hairs, becoming blackish on the sides. Antenne yellow, with very faint darker annulations. Palpi and legs yellow. Anterior-wings grey, densely irrorated with golden-yellow spots, and with darker blackish clouding, especially on the transverse nervules: neuration dark fuscous. Posterior-wings smoky-grey, with grey fringes and fuscescent neuration. In the ¢ the dorsal plate appears to be formed of two portions, the upper rather narrow in its basal portion; its apex divided into widely divergent branches, forming a { : the lower very broad, concave above, chitinous, deeply excised in the middle of its apical edge, each side produced into a broad plate, provided with coarse teeth on the outer edge, and produced down- ward into an acute point. Between the dorsal plate and the upper cover are two very strongly curved strong spines meeting in the excision of the upper cover, and then suddenly curved outward and very acute at the tips. Upper penis-cover only visible in front, directed downward between the inferior appendages, very concave, broad at its base, afterwards narrowed, the edges raised and thickened. Superior appendages long-oval, yellow, very strongly fringed. Inferior appendages rather short, broad, very obtuse, concave within, curved upward, yellow; at the base of the upper edge (connected therewith ?) is a rather small supplementary appendage, having its upper edge prolonged. In the ? the appendages of the 8th ventral segment are in the form of long-oval plates, convergent at the tips. Length of body, ¢,7mm.,?,8mm. Expanse, §, 22 mm., ?, 25 mm. Apennino Pistojese, Central Italy (between Villa OT and San Marcello, 27th July, Haton,1 8,1 9). Of ordinary general appearance,.but very remarkable on account of the extraordinary “dorsal plate’ in the ¢, which is of such a nature as to almost defy description, and which can be best understood by reference to the figures. In the inferior appendages the species approaches P. brevis. PLATE V.—Fig. 1, apex of abdomen of ¢, above; 2, “dorsal plate,” beneath ; 8, apex, from side; 4, an in- ferior appendage, beneath ; 5, apex of abdomen of 9, beneath. N.B.—I think it is both just and convenient to consider geniculata the type ot Plectrocnemia, Stephens (cf. p. 896). Therefore, I propose the following se- quence of species :—geniculata, inflata, prestans (position doubtful), conspersa, brevis, scruposa, letabilis, appennina; the last-named apparently shewing an approach towards Po’ycentropus in some points of its anal structure. HYDROPSYCHID®. 58 Polycentropus Kingi. P. Kingi, McLach., Ent. Mo. Mag., xvii, 254, figs. 1, 2, append. (1881). In size and general appearance much resembling P. flavo-maculatus and multiguttatus. The dark portions of the anterior-wings more pronounced, especially the spots on the costal margin ; apical fork No. 3 in these wings sessile, or with a more or less long footstalk. In the ¢ the dorsal plate is oblong, concave above, with the sides upturned, causing the apical margin to appear as if excised. Superior appendages rather short, yellow, the upper edge longer than the lower, so that the apical edge is very oblique. Intermediate appendages strongly divergent, flattened, rather broad, not very much curved, gradually attenuate to the acute apex. Inferior appendages not often visible in the dry insect, moderate, sub-oblong, convex externally, very hairy, the apical margin excised, and there is an appearance as of an inturned inner portion : from the base of the upper margin proceeds a lanceolate yellow, slightly curved, hairy supple- mentary appendage. Penis very long and stout, yellow, directed downward between the inferior appendages, very obtuse, and at its apex there is a kind of attached process curved over the back. Length of body, ¢,5—6 mm., ? ,53—63 mm. LExpanse, ¢, 145—18 mm., ? ,17—21 mm. Scotland (Strathglass, Inverness-shire, August, J. J. King, very abundant) ; England (near Ambleside, August, J. J. King) ; Portugal (slopes of Foia, and another locality near Monchique, Algarve, 19th and 2lst May; near Alferce, Algarve, 22nd May; near Cea, Beira Baixa, 11th June; Haton, 3 ¢,1 9). Certainly distinct from the previously described species on account of the anal structure of the g, the penis being very extraordinary. It is necessary that individuals in alcohol be examined for more correct discrimination, for amongst many dry individuals I could find only one that appeared to give a tolerably clear idea of the structure of the inferior appendages. The Portuguese examples are larger than the British, but they appear to agree therewith in points of structure. N.B.—It is possible that a still larger pair from Villa Real, Portugal (Haton, 22nd June) belong here. A small ¢ from the Island of Sardinia (Porto Torres, Costa) is referred here with doubt. PLATE V.—Fig. 1, apex of abdomen of ¢, above; 2, same, from side. Polycentropus corniger (x. sp.). . Generally resembling the last, and other allied species; apical fork No. 3 in the anterior- Wings apparently always provided with a short footstalk. In the ¢ the dorsal plate is whitish or pale yellowish, deflexed nearly vertically, slightly rounded at the base, then gradually dilated, the apical margin deeply excised, each angle pro- duced into a long horn-like divergent process. Superior appendages long, yellowish, hairy, also deflexed, somewhat broad at the base, but gradually narrowing to the apex, which is strongly incurved and acute if viewed from above; on the upper edge, near the base, is placed a very slender, much curved, yellowish spine. Intermediate appendages sub-cylindrical, yellowish-testa- ceous, very long and slender, and excessively curved almost in a semicircular manner. Inferior ap- pendages rather small, very hairy, consisting of an outer obtuse convex portion, much excised on its apical margin, and an inturned inner concave portion, the cavity of which appears blackish. Penis, &c., not visible in dry examples. Length of body, $,43—5 mm., 9,5—54 mm. Expanse, g,13—134 mm., 2, 17—18 mm. 5+ First ADDITIONAL SUPPLEMENT, Portugal (near Villa Real, Traz-os-Montes, 21st and 28rd June, Haton,5 2@, 38 9); French Pyrenees (near Quillan, Aude, 8th July, Haton,1 ¢). Identification of this species should be easy, in consequence of the very peculiar points in the anal structure of the ¢. (I omit allusion to this struc- ture in the 2 in this, and other species, because I do not yet appreciate suffi- ciently intelligible characters in that sex; at present, local association is the chief point relied upon). The example of P. corniger from the French Pyrenees remained unde- scribed when the “ Revision”? was completed, owing to insufficient materials. PLATE VI.—Fig. 1, apex of abdomen of ¢, above; 2, same, from side; 3, dorsal plate and intermediate appendages, in front (less enlarged); 4, an inferior appendage, beneath. Polycentropus telifer (n. sp.). Of the ordinary form, colours, and size. The golden-yellow irrorations on the anterior- wings are perhaps paler (almost whitish-yellow) than is usual; apical fork No. 3 in these wings apparently always with a footstalk. In the $ the dorsal plate is short and broad, almost transversely oblong, the apical margin excised, the sides slightly more dilated at the base than at the extremity, the apical angles slightly produced. Superior appendages yellow, hairy, somewhat transversely oblong, the apical margin slightly irregular and excised ; viewed laterally there appears to be a supplementary process proceeding from their lower edge. Intermediate appendages testaceous, comparatively short, slender, spiniform, xot much curved, and extending less than usual beyond the dorsal plate. Inferior appendages hairy, long, lanceolate, upceurved, acute at the tips, concave within; viewed ventrally they are inserted close together, and each is broad at its base, but gradually attenuate to the apex. Penis long, rather stout, much exserted, slightly curved and not deflexed, flattened and concave above, the median portion forming a kind of central keel, which is slightly produced in the middle of the otherwise excised apical margin, and on either side of it, at the apex, is inserted a minute, curved, brown, corneous tooth. Length of body, g,5 mm. Expanse, g, 16 mm. Portugal (stream near Agualva on the road to Cintra, Estremadura, 31st May, 3 6; river Corgo, near Villa Real, Traz-os-Montes, 23rd May, 1 @ ; Haton). No other known species of Polycentropus possesses inferior appendages after the nature of this, and the other anal structure is equally characteristic. PLATE VI.—Fig. 1, apex of abdomen of 6, above; 2, same, from side. N.B.—These additions to Polycentropus prove that the genus, as restricted, is one of the most natural; they prove the practical impossibility of sepa- rating the species by any intelligible characters of form, colour, or size; they prove also the very great value of careful examination of the anal parts of the dg, which present wonderfully good characters, although the same general structure is indicated throughout. Cyrnus cintranus (7. sp.). In general form, colours, and structure, resembling a large form of C. trimaculatus; dis- coidal cell about the same length as the apical fork No. 2; median cellule as in C. trimaculatus. In the ¢ the principal difference in the anal parts appears to be in the so-called “ branches of the dorsal plate ;’’ which are much stouter or broader, ordinarily closely applied one against the other. Length of body, 54—63 mm. Expanse, ¢, 15—153 mm., ?, 17—18 mm. HyDROPSYCHID. 55 Portugal (Cintra, Estremadura, 26th to 80th April, Haton, 3 g,2 9; it appears probable that a 9? from near Monchique, Algarve, 19th May, also belongs here). ! . Although undoubtedly very close to C. trimaculatus, it seems probable that these Portuguese examples are really distinct therefrom on account of the larger size, and the apparent difference in the anal parts noted above. PLATE V.—Fig. 1, apex of abdomen of 6, above; 2, same from side. Cyrnus flavidus, p. 407.—Specimens from the extreme north of the main- land of Scotland (Tongue, Sutherlandshire, J. J. King, very abundant) differ somewhat from the typical form. They are smaller on an average; the an- terior-wings clothed with very pale yellowish pubescence, without any trace of darker reticulations ; posterior-wings white; antenne brown above in the basal third, otherwise pale. In other respects they do not appear to differ from the type-form. Ecnomus tenellus, p. 410.—The discovery of a second species of this genus (ede infra) induced me to re-examine the materials for fenellus, es- pecially as they are from widely-separated localities. I find no differences. The description of the inferior appendages at p. 411, and the figures on pl. xlin, are scarcely sufficient. When these appendages are visible, they are seen to be elongate, flattened, the apex curved inward; on the inner margin, beyond the middle, is a projecting obtuse tooth that seems to arise from a kind of eavity on the inner face of the appendage. (This is faintly indicated in fig. 3 on pl. xlii; but to render it more understandable, I give here a separate figure). PLATE VI.---Fig. 1, an inferior appendage of ¢, beneath, somewhat internally. Ecnomus deceptor (z. sp.). Apparently presenting no tangible differences in size and general appearance from JZ. tenellus. In the ¢ the anal parts are distinctly different. Superior appendages short, nearly oblong ; at the apex there is a small inturned portion provided with blackish spines or teeth (internally, near the base, seldom visible, is a stout, curved, somewhat flattened spine). Inferior appendages projecting much beyond the superior (if extended), hairy, broad, lanceolate, acute, curved in- ward, articulated to a long and broad basal piece (or ventral segment). The appearance of the anal parts varies very greatly according to the degree in which they are extended, or closed upon each other; in the latter case the apex of the abdomen appears almost obtuse. ? unknown at present. Portugal (Ponte de Morcellos, Beira Baixa, 12th June, Haton,1 ¢); Bel- gium (Bouillon and Dinant, 9th and 12th July, McLachlan, 3 ¢). Undoubtedly very distinct from ftenellus by the anal parts of the 3, although otherwise apparently undistinguishable therefrom. In the Comptes-Rendus Soc. Ent. Belg., xxv, p. exxxii, I erroneously re- corded the Belgian examples as tenel/us, which error is rectified in the Comptes- 56 Frrst ADDITIONAL SUPPLEMENT. Rendus, xxvi, p. Ixxviil. As the species evidently has a wide distribution, Trichopterists should carefully examine their examples of fenellus with a view to discovering if deceptor may not be mixed therewith. PLATE VI.—Fig. 1, apex of abdomen of ¢ (with superior appendages only), above; 2, apex, from side; 3, a superior appendage, internally. Tinodes weneri, p. 413.—Add: Portugal (near Cintra, Estremadura, 27th and 30th April, 3ist May, and Ist June, 1 ¢,5 9; Almodovar, Alemtejo, 6th May, 2 6, 2 2; Haton) ; the examples fully equal or exceed the largest British specimens. M. Forel, of Morges, considers that the action of the larve of this insect is one cause of the curious sculpturings on limestone pebbles found on the shores of Swiss lakes. Cf Bull. Soc. Vaud., x1, Proc. verb., p. 29. Tinodes aureola, p. 415, and Supplement, p. Ixxiiii—Add: Island of Sar- dinia (Mt. di Desulo, A. Costa, 1 8); Central Italy (Apennino Pistojese, July, Eaton, not rare) ; North Italy (Val Anzasca, July, McLachlan and Eaton, very common; Val Cannobbio, July, McLachlan). Tinodes assimilis, p. 416, and Supplement, p. Ixxiv.—Add: Portugal (Cintra, Estremadura, 27th April; near Monchique, Algarve, 18th and 19th May ; near Cea, Beira Baixa, 11th June; near Oporto, 18th and 20th June; Eaton, many examples) ; Remiremont, Vosges (July, McLachlan). . Tinodes grisea, p. 414.—Add to the bibliography: MecLach., Journ. Linn. Soc., Zoology, xvi, p. 159 (with description of presumed ¢). Amongst a host of examples of Z. cinerea collected by Eaton in Madeira in November, I found two ¢ that probably belong here, and if so, the affinity with cinerea is much greater than anticipated. Clothing of head and anterior-wings entirely golden. In the ¢ the arrangement of the anal parts is quite after the same plan as in cinerea; the principal difference consists in the parts termed (perhaps erroneously) “intermediate append- ages.’ In cinerea these parts, viewed laterally, are sub-cylindrical, not dilated, and regularly curved downward ; in grisea (viewed in the same position) they are much dilated and somewhat flattened in the apical portion, with a conspicuous tooth (distinct from the spines) that seems to escape from between the two appendages. The processes of the inferior appendages stronger, especially the process of the lower edge, if viewed from beneath. Expanse, 3, 14—16 mm. Naturally there must exist some amount of doubt as to the right of these & to be coupled with the typical 9, but I think such a relationship is very possible. PLATE VI.—Fig 1, apex of abdomen of 6, from side; 2, ‘‘intermediate appendages,” &c., from side (the superior appendage, &c., removed) ; 3, process of lower edge of an inferior appendage, beneath. Tinodes cinerea, p. 414.—Add to the bibliography: McLach., Journ. Linn. Soc., Zoology, xvi, p. 159. Taken abundantly by Haton in Madeira in November; the examples vary creatly in size, irrespective of sex (expanse, 10;—-16 mm.). PLATE YI,—Fig. 1, ‘‘ Intermediate appendages,” &c., from side. HyDROPSYCHID. 57 Tinodes canariensis. T. canariensis, McLach., Journ. Linn. Soc., Zoology, xvi, 159 (1882). Very closely allied to 7. cinerea. In the g the superior appendages are not perceptibly dilated toward the base, almost fili- ‘form throughout. The intermediate appendages appear to have a process below the apex, slightly exceeding them in length. The process of the lower edge of the inferior appendages very slender, greatly curved, its apex obliquely pectinate (7. e., with four or five teeth gradually decreasing in length from the uppermost). Canary Islands (stream beyond San Mateo, Grand Canary, 4550—4650 ft., 11th December, Haton, 1 2). The differences noted (especially the undilated superior appendages), and the locality, render it possible that this is really distinct from 7. cinerea, although undoubtedly very closely allied thereto. PLATE VI.—Fig. 1, apex of abdomen of g, from side; 2, process of lower edge of an inferior appendage, beneath ; 3, same. from side (much enlarged). Tinodes maculicornis, p. 417, and Supplement, p. lxxiv—Add: Portugal (Cintra, Estremadura, 27th April, 38lst May, and lst June, Haton, many examples). Tinodes unicolor, p. 418, and Supplement, p. lxxiv.—Add: Belgium (near Dinant, in July, McLachlan, abundant) ; Switzerland (near Sierre, Valais, 8th July, McLachlan); Greece (Attica, C. W. Dale); Central Italy (Apennino Pistojese, July, Haton, common). Tinodes Zelleri, p. 420.—Add: Switzerland (Vispthal, Valais, 11th July, McLachlan, 2 2). Tinodes merula. T. merula, McUach., Journ. Linn. Soc., Zoology, xvi, 160 (1882). Almost totally deep black, including the clothing of the head, thorax, and wings. Antenne narrowly annulated with yellowish. Articulations of tarsi narrowly yellowish. Anterior-wings having the apex slightly elongate; apical fork No. 3 long and narrow, No. 4 very long and broad ; membrane iridescent. é unknown. In the 2 the ovipositor is testaceous, shorter in proportion than in most other species. Expanse, 12—13 mm. Madeira (streamlet between Cama dos Lobos and Cabo Girao, 1780 it., 20th November, 1 2; “levada”’ above Funchal, 3100 ft., 23rd November, 1 ¢ ; Eaton). Although, as I have previously stated (Joc. ezt.), it is very dangerous to describe species of Zinodes from the 2 only, there can be little doubt that this is distinct, the black species being so few. PLATE VI —Fig. 1, neuration of apex of an anterior-wing ; 2, apex of abdomen of 9, from side. Tinodes foedella (x. sp.). Blackish or fuscous; abdomen paler (somewhat ochreous) beneath; clothing of head and thorax blackish, with a reddish-brown tinge. Antenne stout for the size of the insect, blackish or fuscous, the sutures of the articulations paler, distinctly crenulate within. Palpi fuscescent. Legs dingy testaceous ; tibie and tarsi fuscescent externally, paler at the articulations ; spurs 58 First ADDITIONAL SUPPLEMENT. fuscescent. Anterior-wings broad, rounded at the apex; membrane grey, densely clothed with blackish-fuscous pubescence, having a reddish-brown tinge in certain lights; fringes concolorous with the pubescence, long. Posterior-wings dark grey, iridescent, with grey pubescence and fringes, the latter very long. In the g the dorsal plate forms a broad triangle. Superior appendages yellowish, very long and slender, slightly curved, and very slightly dilated toward the base, clothed with long blackish hairs. Intermediate appendages apparently separate, parallel, straight, each having two or three long spines near, and at, the base, and a terminal spine; below them are apparently several slender processes, one of which is very strong, curved in a sinuous manner, another is regularly and slightly curved downward between the inferior appendages (simulating the penis, but probably not that organ). Inferior appendages having a very large, somewhat oval, basal piece or joint, yellowish, and clothed with black hairs; its lower edge prolonged into a short straight process, somewhat angulate at the tip; the second joint long and slender, slightly curved, obtuse, and somewhat dilated at the tip (much longer than the lower process). Penis apparently stout and much curved, mostly concealed between the inferior appendages. ? with a very long and slender, testaceous, slightly-curved, ovipositor. Length of body, about 23—2? mm. Expanse, 7—8} mm. Portugal (stream from the Estrella, near Sio Romao, about 2450 ft.; near Cea, 1800 ft.; near Villa Real; and near Salamonde; in June; Eaton, 22 examples). By far the smallest Ziénodes known to me, and an addition to what may be termed the group of “ black” species. As the anal structure of the ¢ appears to be somewhat analogous to that of Z. Rostocki (although differing much in minute detail), its position should probably be near that species. PLATE VI.-— Fig. 1, neuration of wings; 2, dorsal plate, superior and intermediate appendages, &c , of ¢, above; 8, apex of abdomen of same, from side; 4, same of 9, from side. Tinodes dives, p. 421, and Supplement, p. Ixxiv.—Add: Central Italy (near Ponte del Lima, Apennino Pistojese, 5th August, Eaton, 1 ¢). Lype auripilis (n. sp.). Fuscous, paler beneath ; clothing of head, &c., blackish, slightly mixed with golden. Antenne fuscous, narrowly annulated with testaceous. Palpi fuscous. Legs dingy testaceous; tibia and tarsi fuscous, the latter faintly annulated with pale; spurs fuscescent. Anterior-wings densely clothed with blackish-fuscous pubescence which is strongly mixed with golden, and somewhat congested into spots of that colour, whereof one on the discoidal cell is the most conspicuous ; fringes concolorous, very slightly mixed with golden: neuration much as in L. pheopa, but apical fork No. 2 appears to extend further inwardly, and the transverse nervule below the dis- coidal cell is placed nearly at the base of this fork. Posterior-wings blackish-grey, with concolorous fringes. In the g the dorsal plate thick, boat-shaped if viewed laterally, not at all attenuate towards the apex. Upper penis-cover thick, occupying most of the inner portion of the apex of the abdomen, apparently divided if viewed from above, extending beyond the dorsal plate. The part termed the “penis” (in former descriptions) thick, semi-transparent, with a tooth (perhaps the true penis?) projecting from its upper edge. Superior appendages slender if viewed laterally (because only their edge is seen), broader and flattened if viewed from above, sub-obtuse, slightly narrowed at the base. Inferior appendages with a short dilated basal joint, aud a long, thinner, slightly-curved, second joint ; viewed ventrally the basal joints of these appendages are separated by a long deep excision, the seeond joints incurved, and dilated at the apex. All the anal parts are yellowish, the superior and inferior appendages clothed with black hairs, which are very long on the former. . 2 unknown. Length of body, about 3mm. Expanse, about 10; mm. HYDROPSYCHID#. 59 Portugal (stream south of Monchique, 1400—1500 ft. 19th May, and slopes of Foia, about 1600 ft., 21st May, Algarve, Eaton, 8 @). Allied to LZ. pheopa, but very distinct in consequence of the form of the “dorsal plate,’ and the partially golden pubescence of the anterior-wings ; in this latter character it forms a sort of parallel to the case of 7. dives in the genus Tinodes. In rubbed examples the golden hairs would no doubt disappear wholly or partially. PLATE VI.—Fig. 1, neuration of apical portion of an anterior-wing; 2, dorsal plate, superior appendages, &e., of ¢, above; 3, apex of abdomen of same, from side. Lype sinuata, p. 424.—As there appears to be a tendency to variation (probably to some extent local) in the form of the “dorsal plate”? in Z. pheopa (cf. Supplement, p. Ixxiv), it is just possible that sinmwata may be only an ex- treme form thereof. I have seen no further examples. Lype reducta, p. 424, and Supplement, p. Ixxv.—A ¢ from Portugal (Agualva, near Cintra, 3lst May, Haton) possibly belongs here. The “ dorsal plate’ is longer, more slender, and slightly curved downward ; in this character it agrees with the example from Saxony mentioned at p. Ixxv. Psychomyia pusilla, p. 426.—I do not feel certain as to the absolute identity of six specimens from Portugal (Oporto, Villa Real, Ruivaes, and Ponte de Morcellos, Haton) with this species. Although altogether resembling it in general characters, the inferior appendages of the ¢ appear to be formed more as in Ps. ctenophora (described below) ; but they want the essential char- acter from which the name of the latter is derived. N.B.—The discovery of Ps. ctenophora induced me to re-examine the whole of the specimens (from many and widely-separated localities) placed in my collection as Ps. pusilla. I think all form but one species, and, as bearing upon the application of the specific term pusilla, it may be mentioned that the examples from Turin (cf. p. 427) are included; these latter are somewhat larger than usual, but I have equally large individuals from Switzerland. Psychomyia ctenophora (w. sp.). Apparently not to be separated from Ps. pusilla by any characters of size, colour, or neuration ; but differs in anal structure, as follows :— In the ¢ the inner edge of the superior appendages (the part that is thickened and blackish in Ps. pusilla) is provided with a series of closely-placed, straight, black teeth, arranged in a comb-like manner, most visible from beneath. The inferior appendages each form two rather long slightly-curved branches, the outermost of which is the shorter, and is broad and irregularly toothed on its lower edge, if viewed laterally. ? apparently similar in structure to Ps. pusilla. Portugal (Ponte de Morcellos, Beira Baixa, 12th June, Eaton, 3 g,4 2). The character emphasized in the above description leaves no doubt as to the specific distinctness of these individuals; it is perfectly constant, and very visible in the 3 ¢ examined. PLATE VI.—Fig 1, apex of abdomen of ¢, from side; 2, same, beneath (shewing the comb-like teeth); 5, same of 9, from side, 60 First ADDITIONAL SUPPLEMENT. Fam. RHYACOPHILIDA. I now indicate the Sections of this Family, as under :— Section of CHIMARRHA (= Section i, p.430). os » RHYACOPHILA (= ,, ii, p. 432). % », AGAPETUS (== 5 Say p- 467). Section iv. is transferred to the Leptocerida, ef. ante, p. 32. Chimarrha marginata, p. 481.—Portugal (near Caldas de Monchique, Algarve, 18th May; Ponte de Morcellos, Beira Baixa, 12th June; near Villa Real, Traz-os-Montes, 23rd and 24th June; Haton), hence this insect has a wider southern range than I anticipated. Rhyacophila torrentium, p. 436.—Add: North Italy (the bridge over the Oglio at Ponte di Legno, 4240 ft., 29th July, Haton, common; Macugnaga, Val Anzasca, over 5000 ft., 15th July, McLachlan, not rare). Rhyacophila Albardana, p. 487, and Supplement, p. Ixxv.—Add to locali- ties in Switzerland: Thusis, 22nd August, McLachlan; also North Italy (Val Furva, about 5000 ft., end of July, Haton). Rhyacophila dorsalis, p. 489, and Supplement, p. lxxv.—Examples taken by myself on the Rhéne at Geneva are certainly dorsalis, and some of them have the penis-sheaths turned downward. It thus becomes advisable to trans- fer the synonym “ Rh. vulgaris, Pict., partim,’ from Rh. obtusidens (p. 440) to Rh. dorsalis. Rhyacophila persimilis, p. 440, and Supplement, p. Ixxv.—Two ¢ from the stream between the Statzer See and Lake St. Moritz, Upper Engadine (McLachlan), differ slightly in having the dorsal process considerably broader and shorter, but the penis is not notably different from that of persimilis, typical examples of which occurred within a short distance. A similar ex- ample was captured by me in July on the river San Bernardino at Pallanza, Lago Maggiore. These appear to show an approach toward Fh. acutidens. Rhyacophila relicta, p. 412.—Add:: Portugal, as a locality (River Corgo at Villa Real, 930 ft., 23rd June; near Ruivaes, 1453 ft., 29th June; near Salamonde, 403 and 2000 ft , 80th June; Haton,5 6,1 9). Rhyacophila rectispina (n. sp.). Constitutes a very distinct Group of Division A, which may (provisionally) precede that of Rh. obliterata. Anterior-wings of ¢ rather broad (slightly narrower and more acute in the 9), much as in Rh. septentrionis and allies (radius apparently furcate at its end in the anterior-wings ; doubt- RHYACOPHILID®. 61 fully so in the posterior) : clothed with bright golden-yellow pubescence, in which are pale grey reticulations and two more or less distinct oblique grey fasciz, one median, the other sub-apical ; grey spots round the apical margin; dorsal blotch distinct, somewhat rhomboidal, margined with grey internally. Posterior-wings pale grey, sometimes slightly irrorated with paler dots in the apical portion, and with small paler spots round the apical margin (occasionally the an- terior-wings are nearly wholly golden, and in these examples the posterior-wings have golden pubescence on the apical portion). In the ¢ the dorsal process is pale yellow, slightly upturned (with the appearance as of a false transverse suture at its base), elongately oblong, the sides parallel, the apical margin deeply excised, leaving the angles prominent. Lateral lobes very small, scarcely visible. Inferior appendages with a long and broad basal joint : second joint shorter, but still long, its upper edge oblique (slightly convex) from base to apex, but with a small notch immediately before the obtuse apex; lower edge straight. Penis-sheaths spiniform, stout, reddish-testaceous, the basal portion much curved in a nearly semi-circular manner, then suddenly geniculate and produced outwardly, at a right angle, into a straight, very acute, spine. Penis reddish-testaceous, elongate, divided at the apex, the upper portion obtuse, with a slight notch above immediately before the apex ; the lower portion produced suddenly downward, at a right angle, into an acute spine placed between the spine of the penis-sheaths (this lower portion appears to be continued as a curved carina to the base of the organ). No visible lower penis-cover. Tooth on 7th ventral segment strong ; that on the 6th stronger than is usual. In the @ the valves of the 8th segment are long and broad, the lower edge much longer than the upper, the apical edge, therefore, very oblique, slightly excised. Tooth on 6th ventral segment very strong. Length of body, ¢,7—10 mm.,?,10mm. Expanse, J, 23—30 mm., ? , 25—26 mm. North Italy (Val Anzasea and its tributary valleys, but rarely extending to the higher parts, July, McLachlan and Eaton, very common, nearly 50 ex- amples, of which only three are $; Val Cannobbio, July, M/cLachlan, not common). It is difficult to satisfactorily locate the Group of which this forms the type, but at present it may be placed between that of fasciata and obliterata. That a visit to a previously unexplored district of North Italy should have resulted in the finding in abundance of such a very distinct species, is a proof, if any were needed, of the apparently inexhaustible nature of this genus. PLATE VII.—Fig. 1, dorsal process, &c., of ¢, above; 2, apex of abdomen of ¢, from side; 3, penis and penis-sheath, from side (more enlarged) ; apex of abdomen of 9, from side, Rhyacophila aurata, p. 448.—The former indication “Switzerland ”’ was, I think, erroneous, through confusion with A. vulgaris. ‘The species, how- ever, does really inhabit Switzerland: I have seen a ¢ (and a doubtful ? ) from Lenz, in the Grisons (Ziirich Museum): it is darker than the Austrian ex- amples, the anterior-wings less golden, with distinct grey reticulation. Rhyacophila contracta, p. 449.—From Portugal (near Villa Real, Traz- os-Montes, 22nd June, Haton) I have 2 ¢ that should apparently be referred here. Although taken together at the same locality, they do not precisely agree in minute details of anal structure. In one, the dorsal process is nearly that of typical contracta ; the penis has its lower angles less produced. In the other the dorsal process is slightly longer, hence more as in proxima, and the lower 62 First ADDITIONAL SUPPLEMENT. angles of the penis are nearly as obsolete as in fraudulenta. Both are smaller (expanse, 243 mm.) than typical contracta, and darker; the anterior-wings with more decided golden pubescence, and more distinct markings. (Vide remarks to Rh. proxima, infra.) Rhyacophila proxima, Supplement, p. lxxvi.—At torrents near Pontresina in the Upper Engadine, about 6000 ft., in August, a species that I refer here was very abundant, and I took about 50 examples: some of them are very large, the 2? sometimes expanding to 37 mm. It occurred also on the summit of the Julier Pass, 7508 ft., and again at a much lower elevation near Thusis. Eaton found the same form at torrents in the Val Furva, not far from Bormio, North Italy, about 5000 ft., at the end of July. It also occurred at Macug- naga, Val Anzasca, over 5000 ft., in July, but was not common. All these examples perfectly agree with the typical proxima in general facies ; but the long series shows evident variation in minute structural details, quite independent of locality. The dorsal process is liable to variation in com- parative length and breadth Gn one example from Pontresina it is nearly ~ triangular ; this I regard as an aberration), and the lower angles of the penis vary from being almost as much produced as in intermedia and contracta, to being as obsolete as in fraudulenta, yet it may be said that there is a facies about all these species or forms that is distinct (in frauwdulenta especially marked). It may be that intermedia, contracta, fraudulenta, and proxima are structural varieties rather than distinct species, the last being in an especially plastic condition ; but further proof is necessary. One ¢ found by Eaton in the Apennino Pistojese, Central Italy, has the dorsal lobe rather shorter than usual in proxima, and the penis as in fraudulenta. Rhyacophila Pascoei, p. 451, and Supplement, p. lxxvii—Add as a local- ity in Switzerland: on the Rhone at Geneva, 5th July (AlceLachlan, 1 8). Rhyacophila vulgaris, p. 452, and Supplement, p. Ixxvii.—I mention this species in order to correct an erroneous idea that I adopted the name in direct opposition (“im directen Widerspruch’”’) to my own statement, at p. 453; cf: Hagen, Zoologischer Jahresbericht, i, p. 581. I thought it was made sufi- ciently clear why I do not adopt the name venusta. Pictet never published that name, and the fact that he sent out specimens bearing the name in MS. goes for nothing. My words, “I have not considered it wise to now recognise after- thoughts indicated in MS.”’ (p. 453), sufficiently explained the retention of the term “ vulgaris”’ for the present species, and it is very applicable, for it is cer- tainly one of the most common of the Swiss species of the genus, and, moreover, nearly all Pictet’s published details for “ vulgaris”? were taken from it, and not from dorsalis or its allies. Rhyacophila meridionalis, p. 454.—I have examined E. Pictet’s type, and find it specifically identical with the examples taken by Eaton. It is small, and expands to only 21 mm. RuYACOPHILID®. 63 Rhyacophila adjuncta (7. sp.). Apparently of the Group of Rh. vulgaris, and allied to meridionalis. Anterior-wings of the ¢ somewhat cinereous, varied and reticulated with brown ; a distinct broad, oblique, cinereous sub-apical fascia, bordered on either side with a brown line; dorsal blotch large and distinct, continued (but narrowed) to the base, cinereous, bordered above with brown or fuscous ; radius indistinctly furcate at its end. In the ? these wings are longer and narrower, and less distinctly fasciated. In the g the dorsal process is rather long, narrow, obtuse, not acuminate, the sides nearly parallel. Lateral lobes small, not dilated, rather shorter than the process. The second joint is less deeply excised than in vulgaris, both the branches stout, the upper somewhat acute at the apex, the lower rather longer and obtuse. Sheaths long, spiniform, curved either upward or downward in the dry insect. Penis very short, slender, straight (seldom visible). Lower penis- cover short. Tooth on the 7th ventral segment very small. In the ¢ the valves of the 8th segment are broad, the appendage prolonged into an obtuse apex, below which the apical margin is rather suddenly excised. Length of body, ¢, 7—8 mm. LExpanse, g, 22—25 mm., ?, 28 mm. Portugal (near Villa Real, Traz-os-Montes, 1000—1630 ft., 23rd to 25th June, Haton,7 g,1 9). In the markings of the anterior-wings this somewhat approaches Fh. munda, and some varieties of septentrionis. It may, 1 think, be conveniently placed in the Group of vulgaris, but it differs from the other species of that Group in the non-acuminate dorsal lobe, and in the short lower penis-cover. In some respects there appears to be affinity with the Group of Rh. dorsalis, notwithstanding the form of the second joint of the inferior appendages. PLATE VII.—Fig. 1, dorsal process, lateral lobes, &c., of $, above; 2, apex of abdomen of same, from side ; 3, penis and sheaths, from side (more enlarged): 4, apex of abdomen of 9, from side. Rhyacophila Rougemonti, Supp!ement, p. lIxxvu.—From Corsica (Dam- ry) I have received a ¢ that is extremely close to Rougemont, and in all probability identical therewith ; there are very slight structural discrepancies when compared with the single type of Rougemonti. The locality leaves some doubt in my mind as to the correctness of that given for the type of Rouge- monti, although the late Prof. de Rougemont assured me, more than once, that, to the best of his belief, the latter was from the neighbourhood of Neuchatel. A ¢ from Corsica, that accompanied the ¢, has the valves of the 8th seg- ment somewhat as in the Group of cntermedia. I dare not conclude that it is of the same species as the @. Rhyacophila lusitanica (n. sp.) - Constitutes a very distinct Group of Division A, and should follow that of Rh. munda, at the end of the Division. Darker than the other Groups of the Division (excepting that of torrentium), the body nearly black above. Antenne darker, fuscous annulated with yellowish. Palpi fuscescent. Legs yellowish ; anterior and intermediate tibiee fuscescent externally, with a pale median space ; all the tarsi fuscescent externally ; spurs fuscescent.. Anterior-wings narrow, fuscescent, clothed with golden-brown pubescence, but thickly irrorated or reticulated with cinereous, forming in- distinct transverse oblique fascise ; the inner edge of the dorsal blotch indicated by a blackish- 64 Frrst ADDITIONAL SUPPLEMENT. fuscous mark; pterostigma blackish-fuscous varied with cinereous; a series of blackish-fuscous spots round the apical margin, interrupted with cinereous dots, which invade the fringes; a very distinct whitish spot at the thyridium; neuration dark fuscous. Posterior-wings fuliginous, iridescent, with dark fuscous pterostigma and neuration. In the g the anal parts are mostly fuscescent. The dorsal process is in the form of a long, laterally compressed, acuminate spine, slightly curved and somewhat directed downward ; it is considerably widened at the base, and is continued as a kind of blunt keel along the surface of the last dorsal segment. The lateral lobes are very small, widely separated, and sub-cylindrical, scarcely extending beyond the margin of the segment. Inferior appendages with a long, straight, basal joint ; the second joint has its wpper edge very short, slightly produced into an angle if viewed from above, the lower long, the apical edge very oblique and straight, so that the apex of the joint is very obliquely truncate. Much internally there appears to be a very short, notched upper penis cover. Penis doubtful (not visible in dry examples). Lower penis-cover yellowish- testaceous, much produced ; viewed laterally it is somewhat widened at the base, then narrowed, and finally extremely dilated ; viewed above it is concave, with the edges slightly inturned, but not symmetrically, the right-hand side of the apex being more dilated than the left. Sheaths in the form of long testaceous piceous spines, the two differing much in form and direction. In the the valves of the 8th segment are long and broad, the upper edge much produced and subacute at the apex, immediately below which the apical margin is deeply excised. Length of body, 9, 6i—8} mm. Expanse, g, 20—23 mm., 9, 24 mm. Portugal (near Sao Romao, Beira Baixa, 1792 ft., 9th June; near Villa Real, Traz-os-Montes, 1730 ft., 22nd June; Eaton, 4 9,1 ?). This curious species is without a parallel or near ally amongst European forms. It certainly belongs to Division A, according to all its characters, much as it differs from other forms in that Division. The dorsal lobe is truly such, and continuous with the segment, notwithstanding its singular form. The second joint of the inferior appendages is somewhat as is seen in the Group of fasezata. The lower penis-cover (for I cannot think this represents a true penis) and sheaths are very extraordinary, not only on account of their form, but also for their asymmetric condition, which can be no illusion caused by alteration in drying, because all the four males essentially agree in this respect. 2h. lusi- tanica is altogether a peculiarly interesting species. PLATE VII.—Fig. 1, dorsal process, &c., of ¢, above; 2, apex of abdomen of same, from side ; 3, dorsal pro- cess, &c., from side (more enlarged); 4, lower penis-cover and sheath, right-hand side (ditto) ; 5, the same, left-hand side ; 6, apex of abdomen of 9, from side. Rhyacophila tristis, p. 456, and Supplement, p. lxxvil.—Portugal (stream- let near Cea, 1792 {t., 4th and 11th June; stream from the Estrella, near Sao Romio, 2442 ft., and near Sabugueiro, 4092 ft., 5th June; near Villa Real, 1730 ft., 22nd and 24th June; near Salamonde, 403 ft., 80th June; aton, many examples). Belgium (stream at the Chemin de Penant near Dinant, 14th July, MeLachlan, common). Rhyacophila aquitanica, p. 457.—Three ¢ from the Vosges (Remiremont and Géradmer; July, McLachlan) agree with the typical individuals from Auvergne. Rhyacophila pubescens, p. 458, and Supplement, p. Ixxviiii—Add: Bel- gium (Route de Froidevaux, near Dinant, 138th July, McLachlan, not uncommon). RHYACOPHILID®. 65 Rhyacophila glareosa, p. 459, and Supplement, p. Ixxviii—Common near Pontresina, Upper Engadine, over 6000 ft., in August, McLachlan. Rhyacophila Meyeri, p. 461.—Several examples from Switzerland (Lo- carno, Ticino) are in the Ziirich Museum. North Italy (Val Anzasca, at dribbling rock-springs in the lower portion, July, MeLachlan and Eaton, not common ; Val Cannobbio, Lago Maggiore, July, McLachlan, more common), As Rh, Meyeri was originally described from only one @ in bad condition, the discovery of additional material enables me to supplement and amend the original description. The anterior-wings are clothed, but not densely, with very pale yellowish pubescence, in which, occasionally, especially on the transverse nervules, are indications of pale grey markings. In the g the two dorsal spines are usually more or less divergent, seldom so parallel as is indicated in my former description, and in the figure on Plate xlix. In the ? the 8th segment is furnished ventrally with a long, narrow, sub-obtuse valve. Expanse, §, 15—20 mm., ? (I have seen only one) 14 mm. PLATE VII.—Fig. 1, dorsal spines of last segment of 6, much enlarged; 2, apex of abdomen of 9, from side. (The figures on Plate XLIX are correct, but the other extreme is here given with respect to the dorsal spines). Rhyacophila stigmatica, p. 461.— Add: Switzerland (common near Pont- resina, Upper Engadine, over 6000 ft., August, McLachlan). North Italy (Val Mazza, 5650 ft., 29th July, Haton, 1g; Val Anzasca, 17th July, WeLachlan, 24,1 ?). | Rhyacophila philopotamoides, p. 463.—From the Vosges (near Gérad- mer, July, McLachlan) I have one g excessively close to this species, if it be not absolutely identical therewith. Glossosoma privatum (n. sp.). The anterior-wings of the $ without a basal callosity, hence the species is allied to G. spoliatum. In colours it generally resembles the other species of the genus. The pubescence of the anterior-wings is more golden (mixed with blackish) than is usual; the second apical cellule truncate at its base (in the examples before me) ; in the posterior-wings this cellule is acute or sub-acute. Intermediate tibiee with a blackish mark at the apex, and another at the median pair of spurs. In the g the spoon-shaped lamina of the 6th ventral segment, and the tooth of the 7th, as ~ usual, the latter very prominent, triangular and acute. Superior appendages with a broad tooth at the upper angle, succeeded by a more slender, somewhat curved tooth; the lower angle pro- duced into a very long, slender, curved process (the opposing processes somewhat forcipate). Intermediate appendages long, sub-cylindrical, very slightly curved, hairy. Terminal ventral process asymmetric (as usual), broad, flattened, scarcely concave above; its apex somewhat suddenly acuminate, acute, with a slight, short, longitudinal apical carina beneath. ? unknown. Length of body,5;—6 mm. LExpanse, 14—153 mm. Portugal (near Villa Real, about 1600 ft., Traz-os-Montes, Haton, 3 ¢). Although agreeing with G. spoliatum in the absence of a callosity at the 66 Frrst ADDITIONAL SUPPLEMENT. base of the anterior-wings, it is otherwise very different by the anal parts. The superior appendages of privatum most resemble those of G. Boltoni, whereas in spoliatum they most resemble those of G. vernale. The presence or absence of the basal callosity scarcely seems to be of generic importance, the species otherwise agreeing so generally in all] points of structure. PLATE VII.—Fig. 1, neuration of base of inner margin of anterior-wing of ¢ (showing the absence of the callosity)* ; 2, apex of abdomen of ¢, from side; 3, superior appendage, above (in outline); 4, terminal ventral process, beneath (ditto). Glossosoma Nylanderi, p. 474.—In the colleetion of Max von zur Mihlen of Dorpat is a @ of this interesting species from Finland, in good condi- tion; it is smaller (expanse, 12? mm.) than the original type. There is no basal callosity in the anterior-wings, but the dividing nervule of the post-costal basal cellules is considerably thickened and inflated (see figure). My former figure (pl. 1) of the anal parts is sufficient for identification, but I do not see the tuft of hairs there represented at the tips of the process on either side of the terminal ventral process, and it is possible these may not always be equal in length (thus probably asymmetric). It may now be considered practically certain that the ? (from the same Dorpat collection) mentioned at the bottom of p. 474 pertains to the same species. PLATE VII.—Fig. 1, Post-costal basal cellules of left anterior-wing of ¢ (very much enlarged). Agapetus incertulus (x. sp.). Closely allied to A. fuscipes and nimbulus, especially to the latter. In the single type, apical fork No. 4 in the anterior-wings extends further inwardly than No. 3. In the ¢ the sides of the upper penis-cover are shorter than the inferior appendages, very broad laterally, testaceous and nearly diaphanous. Sheaths not spiniform, in the form of two laterally flattened fuscous plates, the ends of which extend beyond the inferior appendages, and are nearly truneate and somewhat dilated at the lower apical edge. Inferior appendages, late- rally, as in nimbulus; ventrally there appears to be a slight basal dilatation of the inner edge, forming a tooth or angle, following this is an inner ridge, about the middle of which are two sharp triangular teeth rather closely placed (apical teeth absent or not evident in type). Ventral process shorter and thicker than in nimbulus, its apex more dilated, and more flattened ventrally. Expanse, about 73 mm. Portugal (near Agualva on the road to Cintra, near Lisbon, 31st May, Haton,1 @). Of the distinctness of this individual from fuscipes there can be no doubt. Its relationship with zimbulus is closer, but I think the characters pointed out are sufficient to separate it therefrom ; but it should be remarked that in ném- bulus the penis-sheaths are also not spiniform, but apparently broad and flattened laterally, but not exserted as in incertulus. The neural’ character mentioned is important if found to be constant. PLATE VII.—Fig. 1, apex of abdomen of ¢, from side. * Upon comparing this figure with that given for spoliatum (Pl L, fig. 1), a slightly different arrangement of the basal cellules is apparent. My 6 type of spoliatum is not now in a condition that will enable me te confirm the accuracy of the figure given for that species. RHYACOPHILID. 67 Nore.—One ¢ and two 9? of an Agapetus from near Monchique, Algarve, 19th and 21st May, Haton, are near fuscipes, but distinct therefrom according to slight structural differences present in the ¢ (which was in alcohol) ; it is scarcely safe to name and describe it without having examined more materials. Agapetus laniger, p. 480, and pactus, p. 481.—It now appears to me that the course I took with regard to these two insects was, if not “ rash,” certainly “ill-advised” (cf p. 481). In the beginning of July, 1882, I took at Geneva 2 g and 1 2 of my pactus, and am therefore constrained to believe that Pictet’s laniger was this insect, and not the Pyreneean form to which I applied the name. The difficulty arose in the main from the absence of the minute fork at the termination of the radius in the posterior-wings in the ? types of laniger, Pict., examined by me, a character too unstable to warrant serious consideration. The two species should, therefore, stand as follows (my former laniger being renamed) :— Agapetus delicatulus. A. laniger, McLach., Rey. and Synops., 480 (¢ only), pl. 1, figs. 1—3, nec Pict. A much smaller and more delicate insect as a rule than the true laniger. The radius in the posterior-wings is sometimes fureate at the end. The anal parts of the ? do not show sufficient characters in dry specimens to merit special mention. At present known only from the Pyrenees. Agapetus laniger. Rhyacophila lanigera, Pict., Recherch., 195, pl. xvi, fig. 19 (1884). A. laniger, Hag., Stett. Zeit., 1859, 162; McLach., Rev. and Synops., 480 (? only), pl. 1, fig. 4. A. pactus, id., op. cit., 481, pl. 1, figs. 1—8 (1879). The condition of the branches of the upper penis-cover is subject to much and deceptive variation in dry individuals. In two ¢ taken together at Geneva the branches are much longer than the inferior appendages, and much exserted (as in my figs. 1 & 2 for “A. pactus”’) in one, much shorter than those appen- dages, and not exserted, in the other. In two ¢ from Portugal (near Ponte de Morcellos, Beira Baixa, 12th and 14th June, Eaton), the branches are shorter than the appendages in both, and apparently somewhat thicker than in other examples. I have also taken this species on the Rhine, near Basle, in August. The radius is very rarely not furcate at the end in the posterior-wings. Pseudagapetus diversus (7. sp.). Closely allied to Ps. insons; differs as follows :—Pubescence of head and thorax golden or golden-brown. Pubescence of anterior-wings golden or golden-brown, denser, the membrane less iridescent (as it is also in the posterior). Legs paler: the intermediate tibie and tarsi dis- tinctly (though only slightly) dilated in the ¢. 68 Frrst ADDITIONAL SUPPLEMENT. In the ¢ the superior appendages narrower, longer, and less triangular. The apex of the inferior appendages apparently more obtuse. The process on the 6th ventral segment broader, its apex nearly semi-circular if viewed ventrally : tuft of hairs on the 7th ventral segment less indicated. Size about as in Ps. insons, or slightly less. Portugal (near Cea, 1792 ft., Beira Baixa, 4th June, 1 ¢ ; near Villa Real, Traz-os-Montes, 22nd June, 1 ¢, 2 9 ; Eaton). There can be no doubt that these individuals are specifically distinct from Ps. insons, although quite of the same general structure. PLATE VII.—Fig. 1, apex of abdomen of ¢, from side. N.B.—It should be noted that my words “slender in the ¢”’ relating to the intermediate tibie and tarsi of the 9 (of Ps. znsons), in the generic descrip- tion at p. 485, are hardly strictly correct. There is just the slightest approach to dilatation: this is much more marked in Ps. diversus, though the dilatation is still much less than in dgapetus and Synagapetus. CATAGAPETUS (uw. g.). Allied to Synagapetus and Pseudagapetus. Anterior-wings of the ¢ clothed with thickened erect hairs, excepting the apical portion; those of the ? with ordinary adpressed pubescence. Neuration of anterior-wings nearly as is usual in Agapetus and allies: in the posterior-wings the sub-costa becomes confluent with the radius,* there is a small closed discoidal cell, and apical fork No. 2 extends to the anastomosis. Intermediate tibie and tarsi dilatedin the 9. Anal parts somewhat as in Pseudagapetus, but the process or lobe on the 6th ventral segment in the @ is short and very broad, not extending beyond the margin of the segment. A very distinct genus, allied to Agapetus, &c., but differing especially in the closed discoidal cell of the posterior-wings, and the confluent sub-costa and radius in these wings. The clothing of thickened erect hairs on the anterior- wings of the g is analogous to that seen in (both sexes of) Ptilocolepus, but is less extended and finer, and the neuration, &c., differ considerably. Catagapetus nigrans (n. sp.). Black ; head and pronotum clothed with black (somewhat brownish on the warts) pubes- cence. Head (denuded) with five yellowish warts, viz.: one, small and rounded, between the antennee ; two, small and transverse, pointed at either end, near the middle of the disc; and two larger, long-oval, and transverse, posteriorly. Pronotum with two distant, short-oval, yellowish warts. Humeral callosities yellowish and conspicuous. Antenne strong, blackish. Palpi blackish. Legs fuscescent, somewhat testaceous at the articulations (the anterior pair nearly wholly with a testaceous tinge) ; posterior tibiee with long greyish hairs, which are longer in the g than in the 9. Abdomen (dry) with reddish lateral lines; clothed with sparse silvery hairs, especially beneath. Anterior-wings (when in good condition) clothed with intensely “9 * It should be remarked that there is here an anomaly in what are apparently the sub-costa and radius. Ordinarily the radius is thickened and the sub-costa slender, but here the nervure that from its position should represent the sub-costa is thickened up to its confluence with what appears to be the radius, which latter remains slender for all its length. RHAYACOPHILID. 69 black pubescence (differing in its nature in the sexes as noticed in the generic description) ; membrane (denuded) dark smoky-grey, densely and finely punctate: neuration strong, black ; in the anterior-pair apical fork No. 1 is acute at its base; No. 3, long: fringes long, black. Posterior-wings scarcely paler than the anterior, with very long fringes. In the g the anal parts are not easy to discriminate in the dry insect. The superior appendages appear to be represented by minute lateral setiferous tubercles. Last ventral seg- ment continuous, dilated laterally, dark, and shining. From within this segment proceed what I consider to be the inferior appendages in the form of somewhat oblong flattened dusky plates, the apex of which is obliquely truncate. More ventrally are two other plates, rounded on the margin, from which proceeds the penis-cover (penis ?), which is somewhat long, pale yellow, and directed upward. Lobe of 6th ventral segment very short and broad, not projecting beyond the margin, its rounded edge scarcely free. On the 7th ventral segment is a tuft of straight yellow bristles. | In the ? the supplementary suture on the 6th and 7th ventral segments is continuous, but its ventral edge is scarcely free, though somewhat thickened. A tuft of stiff, straight, yellow bristles on the 8th ventral segment. Ninth segment somewhat divided into a small and narrow dorsal, and a large sub-quadrate ventral, portion. Ovipositor stout, yellow, with very long and slender straight cylindrical appendages. Expanse, 8}—11 mm. Apennino Pistojese, Central Italy (between Villa Margherita and San Mar- cello, 2160 ft., 27th July ; Font Vacaja Lima, 4410 ft., 2nd August; near Ponte del Lima, 4130 ft., 5th August; Haton,7 ¢,16 ¢). PLATE VII.—Fig. 1, neuration of wings; 2, apex of abdomen of ¢, from side ; 3, same of}. N.B.—From Portugal (slopes of Foia, near Monchique, Algarve, 1650 ft., 21st May, Eaton) I have 1 ¢ that certainly pertains to this genus, but probably represents a distinct species. It is larger than C. nigrans (expanse about 14. mm.), the warts of head and thorax clothed with golden (or golden-brown) pubescence, the pubescence of the anterior-wings golden-grey ; and I think there are structural differences, but it is not prudent to describe it in the absence of the ¢. PTILOCOLEPUS, p. 488 Further materials, and more minute examination, have convinced me that my former description of the anal parts of the ¢ was not quite correct, and further that there are at least two species of the genus. The elongate hairy process which I termed “inferior appendages” may be truly such, but I am not sure that it is separated into two parts, and if not it might be regarded as a lower penis-cover rather than as appendages. Inside this (and with difficulty separable from it) is a pair of much larger testaceous blades (“the yellow furcate process ”’ of my former description), which I think certainly represent penis-sheaths: but it is only occasionally that these are sufficiently exserted for perfect discrimination. Very frequently nothing is visible but the tips of these blades. Ptilocolepus granulatus, p. 490, and Supplement, p. Ixxix.—Add to locali- ties: Belgium (near Bouillon, 10th July, McLachlan) ; North ltaly (Val Anzasca, &., common, McLachlan and Eaton); Central Italy (Apennino Pistojese, Haton). 70 First ADDITIONAL SUPPLEMENT. The anal parts of the g seldom much exserted. The inferior appendages (?) gradually becoming rather broad. Penis-sheaths furcate laterally, the upper branch long, and more or less slender, curved downward ; the lower branch short. PLATE VILI.--Fig. 1, lateral view of anal parts of ¢ in an example in alcohol from the Pyrenees, flattened out between glass ; 2, the same as seen in a dry example from Belgium, in which the parts are more than usually exserted. N.B.—In a g example from Saxony the sheaths are fureate, but the upper branch seems to be more obtuse. If this should prove constant, it may be that turbidus, Kol., is distinct from granulatus, Pict. Ptilocolepus extensus (w. sp.). Of the same size and general appearance as in granulatus. The whitish-hyaline spots at the thyridium and arculus (especially the former) appear to be large and more distinct than is usual for that species. In the dry ¢ the anal parts are greatly exserted in all the individuals examined. The in- ferior appendages (?) much narrower. Penis-sheaths very long, narrow, but gradually dilated on the lower edge, not furcate if viewed laterally. apparently as in granulatus. Portugal (between Sao Antonio and Coimbra, Beira Baixa, 3rd June, 1 3; near Cea, about 1800 ft., Beira Baixa, llth June, 2 ¢,1 9; a ? from near Monchique, about 2800 ft., Algarve, 21st May, probably belongs here ; Haton). These appear to be quite distinct from granulatus, according to the anal characters. PLATE VII.—Fig 1, lateral view of anal parts of ¢, as seen in dry examples. Fam. HYDROPTILIDA. Agraylea pallidula, p. 507.—A ¢ from South Tyrol (Riva, on Lago di Garda, lst August, Haton) agrees structurally with the type-form, but the ground-colour of the anterior-wings is very pale grey, in which are numerous, more or less confluent, paler spots. It seems natural that an Agraylea should be spotted, and this condition may probably prove to be more general in 4. pallidula than the small material as yet to hand seems to suggest. Moreover, A. multipunctata has an unicolorous pale form, and an unicolorous black form. A, pallidula has, at present, mostly been found only singly and in very widely- separated localities. | Allotrichia pallicornis, p. 509.—Add: Portugal (Cintra, Estremadura, 1st June, 1 g,3 9; Villa’ Real, Traz-os-Montes, 24th June, 1 9; Haton); Apen- nino Pistojese, Central Italy (Haton, 3 8,2 ?). The ovipositor of the 2 may be retracted altogether, or may be much more extended than is indicated in my figure. Hydroptila sparsa, p. 511.—I refer here, with slight doubt, examples from Portugal (Cintra, 26th and 27th April, Eaton). | HYypDRopriLip®. 71 Hydroptila longispina (n. sp.). Antenne about 30-jointed in the g, and about 25 in the 9, fuscous throughout (in the examples before me). Head, &c., clothed with cinereous pubescence, becoming blackish on the face. Legs dingy-testaceous, the femora fuscous or fuscescent ; fringes silky-whitish. Anterior- wings blackish, the raised hairs mostly deep black; the markings whitish, consisting of a vague basal streak on the inner margin; a maculose ante-median fascia, more marked as spots extending into the fringes on the costal and inner margins, two opposite post-median spots, one on the costal, the other on the inner, margin, and the apex also has whitish hairs extending into the fringes. Posterior-wings grey, with concolorous fringes. In the ¢ there is a somewhat boat-shaped dorsal process or plate, concave beneath, acute, if viewed laterally. From beneath this proceed two extraordinarily long slender processes, which appear to be united at the base ; one of these is only slightly curved, flattened and dilated before the fine apical portion ; the other is much more slender, not dilated, much curved, and often spirally twisted round the stouter process (but the position is varied in dry examples). Beneath the thickened common base of these processes there appears to be a small hook, directed downward if viewed laterally. Lobe of ante-penultimate ventral segment very long, very slightly curved, and somewhat dilated at the apex. The 2 presents no special anal characters. Expanse, about 53—6 mm. England (Ambleside, common, J. J. King). It appears to me, from several points of view, that the nearest ally of this insect is H. femoralis, but specific identity therewith is very improbable. The anal structure is somewhat similar, so far as regards the dorsal process, but in no specimen of femoralis have I seen any approach to the presence of the two extraordinary spine-like processes that are so conspicuous in longispina, and which were present in all the examples examined, but varying slightly in amount of exsertion, and considerably in relative position (owing to desiccation). I cannot consider either of these spines as representing the penis, and regard them rather as “sheaths’’ unequal in development (if either of them is really the penis, it must be the stouter and less curved one). PLATE VII.—Fig. 1, neuration of anterior-wing ; 2, apex of abdomen of ¢, from side ; 3, same, beneath, Orthotrichia atra, p. 520.—This is a true Stactobia, and thus becomes :— Stactobia atra. Add to previously-given bibliography :—/S. atra, McLach., Journ. Linn. Soe., Zoology, xvi, 161. Eaton found it commonly in Madeira in November, between Cama dos Lobos and Cabo Girao, and below Sant’ Anna; also one example in Grand Canary, near Teror, 1600 ft., 9th December. The following is an amended description :— Black ; clothing of head and thorax deep brownish-black. Antenne blackish-brown, 18- or 19-jointed. Head (denuded) transverse; the disc elevated in the fresh insect, finely punctate ; posteriorly are two very large, pyriform, punctate warts; (in the dry insect, along the middle, longitudinally, is a raised keel, dilated anteriorly and posteriorly ; on each side of this is a deep cavity, caused by the collapsing of the sides of the disc, in which, close to the eyes, the minute lateral ocelli are seated). Legs blackish-brown, with a slight silky testaceous tinge, hinder pair 72 First ApprITrionaL SUPPLEMENT. with very long concolorous fringes. Abdomen blackish, clothing greyish-brown. Anterior- wings densely clothed with black pubescence (becoming brownish by age) ; along the radius are a few, distant, erect (or out-turned) yellow hairs, and there are similar distant down-turned yellow hairs along the inner margin (these hairs are only visible in specimens in good condition) ; the very long fringes concolorous with the pubescence. Posterior-wings grey, iridescent, with dark grey fringes. In the g the only distinctly visible anal part is a testuceous, semi-transparent, laterally flattened, obtuse process (which can be more or less exserted), and on either side of it there appears to be a closely-applied piece produced into a spine at its apex (a down-turned lobe on either side at the base of this process, is a little uncertain). Inferior appendages almost spini- form, with incurved tips. Lobe of ante-penultimate ventral segment very long, less clavate at its apex than is the case in the other described species of the genus. In the 2 the apex of the abdomen ends in a testaceous ovipositor, with two slender apical processes (this ovipositor:can be nearly wholly retracted and also greatly extended). Expanse, 53—7 mm. This being so much larger than the other described species of the genus, I was enabled to secure a better figure of the neuration, which proves that in Stactobia there are at least two transverse nervules in a line above the ‘arculus in the anterior-wings (possibly there is also a third, closing the cellula thyridii, but I could not detect it). The few yellow erect hairs on the anterior-wings are analogues of those that produce the spots in the other species. Stactobia fuscicornis, p. 517.—Add: Portugal (between Cea and Sabu- gueiro, Beira Baixa, 3490 ft., 7th June ; between Oporto and Santa Anna, 50— 200 tt., 18th June; near Villa Real, Traz-os-Montes, 1630 ft., 24th June; Eaton) ; North Italy (Val Anzasca, abundant at dribbling rock-springs in the warmer parts, in July, McLachlan and Haton; Val Cannobbio, McLachlan) ; Central Italy (between Villa Margherita and San Marcello, Apennino Pistojese, 2510 ft., 27th July, Haton). T am of opinion that it was this species I saw at sunny rock-springs in the Val Levantina, Ticino, Switzerland, but failed to preserve examples. Orthotrichia angustella, p. 519.—Add: Portugal (near Cintra, Estrema- dura, 3lst May and Ist June; Ponte de Morcellos, Beira Baixa, 12th June, Eaton). Oxyethira spinosella (n. sp.). O. Apparently scarcely to be distinguished from O. costalis in general appearance, slightly smaller ; perhaps the fringes of the legs are darker, and the anterior-wings have more decided blackish longitudinal streaks in the basal half, and the costal fringes more mixed with glackish, so that the wings are generally darker, the pale (whitish) markings as usual. In the g the penis is whitish and semi-transparent, zts apical portion dilated (asymmetri- cally) on one side only (perhaps accompanied by a single sheath). Inferior appendages with three sharp blackish apical spines, whereof the median is the longest, the inner finer and placed a. sp., MeLach., Journ. Linn. Soc., Zoology, xvi, p. 162 (noticed). somewhat distant from the two others. Madeira (Ribiera Fria near Faial, 25th November ; “levada”’ on cliff below Sant’ Anna, 26th November; Haton,3 ¢,1 92). HyDROPTILIDS. 73 Certainly distinct, in consequence of the spines at the apex of the inferior appendages ; the asymmetric dilatation of the apical portion of the penis ap- pears to be constant. More materials, and fresh, or in alcohol, are necessary for more exact details of the anal parts. Oxyethira unidentata (. sp.). Similar to O. costalis in general appearance. In the g the anal parts are arranged after the same plan. The penis long, rather slender, with a sharp tooth on the left-hand side (viewed from beneath) just below the apex: there ap- pears to be a single longer sheath placed on the right-hand side (from beneath). Inferior appendages (of which only the tips are visible in dry examples) apparently stouter than in costalis, the tips sub-obtuse and turned outward. Portugal (streamlet west of Silves, Algarve, 17th May, Haton, 7 @). This must be distinct from costalis (according to the anal parts of the @). It is difficult to make a satisfactory figure from dry examples only, in consequence of the hairs; never more than the tips of the inferior appendages are visible, and the form of the penis and its sheath differs (through desiccation) somewhat in each individual, but the unilateral tooth is always present. N.B.—It was not found possible to reproduce the figures I had made for Stactobia atra and Oxyethira spinosella and unidentata, which must be reserved for another occasion. Also it was not found possible to notice at least three undescribed species ot Hydroptilide in my collection without the chance of delaying the publication of this “ First Additional Supplement.” These are likewise reserved for another occasion.
