Since writing the report on the Acridiidae1 a few additional speci mens collected after the main expedition had started home have been received. These are of sufficient interest to merit an additional report. Family LOCUSTID.E (OEDIPODIN^). TREMEROTROPIS OCHRACEIPENNIS ? Blanchard. A single female specimen doubtfully referred to this species from Coropuna, taken in October. The altitude given is 14,500 feet. TRIMEROTROPIS SIGNATIPENNIS Blanchard. One pair bearing same data as the preceding species. FamUy CYRTACANTHACRID^ (ACRIDIIDJE). SCHISTOCERC A MACTJLATA, new species. Of medium size, and with the tegmina regularly and coarsely maculate with fuscous, and the pronotum longitudinally fined with the same color. Head rather narrow but fairly high, not prominent, the eyes also narrow, being fully twice as long as wide and plainly longer than the anterior margin of the cheeks below them, separated on the vertex by a space equal to the widest portion of the frontal costa; fastigium nearly twice as wide as long, very shallowly sulcate and with cqarse antero-lateral carinse; lateral ocelli large, pallid, touching the com pound eyes; frontal costa moderately prominent, shallowly sulcate at the ocellus and below. Pronotum rugoso-punctate, narrow in front, the anterior lobe a little expanding caudad, the hind lobe much more rapidly so; the median carina fairly prominent and deeply ' Proceedings U. S.

Tegmina ample, tapering but little apically, extending beyond the tip of the abdomen and apex of the hind femora nearly double their width; wings broad. Anterior and middle legs rather slender, the hind femora short, robust at base, slender apically, the external carinae prominent; hind tibiae noticeably sinuose and also provided with prominent external carinas, 9-spined externally, 11-spined internally, the inner ones decidedly larger than the outer. Pros ternal spine moderately coarse, decidedly transverse, the sides parallel, the apex broadly rounded, gently directed caudad but not curved. General color brunneo-cinereous, strongly maculate, mottled, streaked and flecked with fuscous. Tegmina coarsely maculate on disk, the maculae on the apical half tending to form obliquely trans verse bands, anterior and posterior areas also distinctly mottled with the same color. Pronotum plainly marked with alternate longitudinal pallid and fuscous bands, the middle of the lateral lobes provided with a quadrate pallid macula. Vertex and occiput showing traces of lateral fuscous lines, between and below these lines cinereous except for an inconspicuous fuscous line extending partly across the cheeks below each eye. Hind femora with a pallid external disk; upper margin showing traces of two transverse fuscous bands, lunules and base of tibiae black, the genicular lobes dirty white, the carinae very conspicuously black mottled; the tibiae cinereo-purple, the spines pale, black-tipped. Hind margin of abdominal segments prominently dotted with fuscous. Wings pellucid, becoming yel lowish basally, the principal veins and the transverse ones on apical portion infuscated. * Length of body, female, 42 mm.; of pronotum, 9.5 mm.; of tegmina, 43 mm. ; of hind femora, 23.5 mm. Habitat. — The only specimen at hand was taken at Chuquibamba, Peru, during October, 1911. The label bears the note "10,000 feet (Yale Peru expedition)." Type.— Cat. No. 15598, U.S.N.M. This insect is rather closely related to both S. columbina Thunberg and S. interrita Scudder, the former species coming from Colombia and the latter from Peru. It is also related to an insect found in the windward of the West India Islands and Trinidad, and that has been referred erroneously to Thunberg's species. It is likewise related to S. maculipennis Bruner, which latter locust will shortly be described in a forthcoming paper soon to be published in the current volume of the Annals of the Carnegie Museum.
