Patch For many years after Linnaeus gave “the” rose aphid the specific name of rosae, this term proved sufficiently elastic to embrace all the large green or pink aphids found upon the rose. Just how many of these there may prove to be when the sub- ject has been entirely covered it is still too soon to say. It is certain, however, that there are at least three species of the genus Macrosiphum common on the rose in Maine and that each of these has two distinct color varieties, one pink and one green. Of these ikf. rosae proper is not known to migrate and it does maintain a continuous residence upon the rose. This cir- cumstance would not preclude the possibility that it has a sec- ondary food plant which is used as a summer resort for it is not uncommon for a species with a definite spring and fall mi- gration to and from the summer food plant to continue also to colonize its primary food plant (that upon which the overwin- tering egg is placed) during the summer months. The second of the pink and green rose aphids, Macrosi- phurn solanifolii, also deposits its eggs upon the rose in the fall where it may be found in heavy colonies during the spring and early summer, when it migrates for the most part to a great variety of summer plants, though it may, besides, keep up its connection with the rose during the summer. In Maine, and in perhaps most other parts of the United States, this species works greater havoc in potato fields than on other vegetation. The heavy infestation of the potato may be encouraged by the well nigh universal abundance of these plants putting forth their most succulent growth at the time M. solanifolii migrates from the rose ; and its threat against this crop is evidently a ^Papers from the Maine Agricultural Experiment Station : Ento- mology No. 102. 1 206 Maine Agricultural Experiment Station. 1919. two-fold one, — the direct damage due to its feeding habits, and its indirect but possibly even more serious harm of serving as a carrier of potato disease.* As there are, at present, no items concerning M. rosae in Maine which are different from those available in publications from other sources; and as M. solanifolii has already appeared in several bulletins of this Station, the present account will con- cern chiefly the third pink and green aphid of the rose which is here described as a new species though it may prove to have an old world name when its geographical distribution and food plants are better known. MaCROSIPIIUM I’SEUDOROSAE N. SIL Alatc viviparous female: General color polished rose red or green. Beak short and stout. Antennae black, so heavily pigmented that it is difficult to prepare a mount which shows the distribution of the sensoria; III with 14 more or fewer sen- soria in a row extending usually about five-sixths its length; IV without sensoria; the relative lengths of segments III to VI may be indicated; 13, ii, 8, 2-I-13. Fore wing with veins slender and about uniform. Second joint of ist tarsus exclud- ing claw about three-fourths length of base of VI. Cornicle deep black, usually not much shorter than III or anal vein of fore wing, though considerable variation is possible, and reticu- lated for about one-fifth its length. Cauda yellowish. Apterous viviparous female: General color same as in the .-alate female, both color varieties being common. Antenna with single row of sensoria extending about half the length of III, sometimes farther. (See also remarks on reared individuals p. 208). Descriptions of both of the foregoing are from wild rose material collected July 19, 1918 by Mr. George Blodget.

Aphid Food Plant Catalogue. 207 My attention was first directed to this species by a collec- tion made by Mr. George L. Blodget from golden ragwort (Senecio aureus L.) July 3, 1918. This material was mixed with Macrosiphum solanifolii from which it was easily sepa- rated by its black antenna and cornicle. A second search in the same locality revealed the fact that both these species were also present on the numerous wild roses on the bank of the Penob- scot very near the ragwort. Of course the next step was obvious and preparations were made for transfer tests from wild rose to ragwort. The potted plants of ragwort were slow in getting a start and only the rosettes of basal leaves remained fresh for the duration of the test. By July 24, these plants seemed in safe condition to use and on that date two viviparous females of the pink color vari- ety were removed from wild rose and caged on the ragwort. One was apterous and the other alate, and both were somewhat restless during the first day, a condition accounted for, perhaps, by the fact that the new food plant was making less succulent growth than the rose they had been feeding upon. July 26, both aphids were feeding head down and both producing young. Ten nymphs present and all were feeding. August 2, both aphids were still feeding and producing young, 30 nymphs being present. Their manner was to colonize one leaf and then move to freshly growing uninfested leaf or to a separate plant. The apterous female was removed to avoid overstocking the caged ragwort. August 9, several apterous viviparous females matured and were removed. August 13, several more mature apterous viviparous fe- males were removed. September 12, the first alate viviparous female and several mature apterous ones were removed and, due to the condition of caged plant, the test was discontinued. The point at issue, however, has been established. Cap- tives of Macrosiphum pseudorosae were capable of living upon ragwort and their progeny matured upon the secondary host plant. There seems no reason to question the conclusion that the ragwort material first taken in July had had its origin in migrants from the rose as was the case with Macrosiphum solan- 208 Maine Agricultural Experiment Station. 1919. ifolii. And, as with Macrosiphwn solanifolii, the migration of MacrosipJmm pseiidorosae was not entirely complete for strag- glers remained upon the rose during the summer with both these species. All of the reared cage individuals were of the rose pink color variety as, it will be remembered, were the two females from which they were descended. Plans were made for continuing observations earlier in the season during 1919 and a report upon this interesting aphid was delayed with that in mind. But, although the same locality was well patrolled this spring and summer not a single specimen of Macrosiphum pseiidorosae was found. It seems better, therefore, to publish what has been ascertained with a view to throwing open the situation for comparison in other parts of the country. It would not be surprising if the name pseiidorosae should fall as a synonym to rosaeiformis Das, but material is not avail- able for comparison and it is too far a cry from Maine to India to risk on the slight acquaintance we have either with the rose — ragwort species here or the “Punjab Rose Aphid” described by Das. A full list of the food plants in India and America may give a clue leading both aphids to some older name. The same insect or one very closely allied is found in Maine upon Geum and Cinquefoil (Potentilla) of the rose family and upon certain other members of the Composite Family besides the golden rag- wort, but in no case was it definitely ascertained whether it actu- ally was Macrosiphum pscudorosae or a species closely resembl- ing it and a further acquaintance with this aphid is desirable. Macrosiphum pseiidorosae is a variable species with refer- ence to several characters which are usually available for specific determination, such as the relative length of the cornicle with reference to antennal segment III and the number of antennal sensoria. For instance the individuals reared on Senecio from two known females removed from rose showed the following variations. 1'he size was in all the caged individuals, smaller than their rose progenitors a circumstance which might easily be accounted for by tlie fact that the basal rosettes of ragwort ](;aves were not making succulent growth. In the apterous vivi- parous females the relative length of cornicle to 111 of antenna. Aphid Food Plant Catalogue. 209 about nine-tenths remained approximately constant in most cases though in one of the September individuals the cornicles were dwarfed to ten-seventeenths the length of III. In this same aphid there was but one sensorium on III as against 3 to 5 in most of the ragwort specimens and 6 to 8 in the summer host collections. The key given on pages 216-218 has proved useful in sepa- rating Macrosiphu'in psciidorosae from other New England members of the same genus, and is offered here on the chance that it may be of some slight service in Eastern United States, though the writer has not yet been able to construct a key to these species which would seem to be at all adequate in view of the wide range of individual variation of which these aphids are capable. Several New Species The publication of the key necessitates the description of several species which have been accumulating in the collection until it is difficult to handle them any longer under manuscript names. Not enough is known about most of them to warrant giving them much space but it will serve to put them on record with reference to their food plants and possibly to link into data from other collections. MACROSIPHUM CARPINICOLENS N. SP.
