Collet es {lycii subsp. ?) pe7'twicus, sp. n. 

 ? . — Lcnp;tli about 8 mm., anterior wing 6, 

 Black ; hair of head' and thorax ratlier k)ng and abundant, 

 below Avhite, above faintly tinged with yellowish, the vertex, 

 disc of mesothorax, and scutellum with an admixture, not 

 very conspicuous, of fuscous hairs ; mandibles rather dark 

 ciiestuut-red ; malar space long, not quite H times breadth 

 of base of mandibles ; labrum with a strong median groove, 

 and faint ones on each side ; clypeus shining, inipunctate 

 laterally, in the middle with a very broad median depression 

 which is sparsely punctured, its sides above forming a pair 

 of blunt shining ridges ; supraclypeal area smooth and 

 shining ; eyes very prominent ; no distinct prothoraeic 

 spines ; mesothorax brilliantly shining, Avith minute very 

 sparse punctures; scutellum shining, the posterior half well 

 punctured ; area of metathorax a transverse band, with 

 many closely set ridges ; posterior face of metathorax with 

 a large, shining, smooth, triangular area, but the other parts 

 roughened ; pleura shining, with sparse small punctures ; 

 tegulse reddish testaceous. Wings hvaline, very faintly 

 brownish, the rather small stigma ruio-fuscons ; nervures 

 fuscous ; second s.m. very broad, receiving first r. n. in 

 middle. Legs black, with dark rufous tarsi, their hair pale, 

 a little fuscous on outer side of hind tibiae. Abdomen rather 

 narrow, brilliantl}'^ shining, with only the most minute, 

 hardly visible, punctures, these scattered ; hind margins of 

 segments broadly pale rufous ; basal half of first segment 

 with long greyish-white hair ; second (most clearly toward 

 base) and the remaining segments with short greyish tomen- 

 tum, more or less covering the surface ; no liair-bauds ; apex 

 Mith fuscous hair, 



Hab. Piura, Peru (C H. T. Townsend). 



This is smaller than C. lycii, Jorgensen, from Mendoza, 

 but evidently closely allied. The localities are, however, 

 over 2000 miles apart, and the partly fuscous hair of the 

 head and thorax above, the entirely red mandibles, &c. are 

 distinctive of the Peruvian insect. In the elypeal structure 

 there is a resemblance to C. sulcatus, Vachal, from Chili. 

 The known Peruvian Collates may be separated thus : — 



Legs with hair mostly black striginasis, Vachal. 



Legs with pale hair 1. 



1. Malar space very short injlatus, Vachal. 



Malar space long peruvicus, Okll.
