 granular opimus coloradensis.

1911, p. 411. 



This subspecies varies in having the pectus black or with a pale spot. 

 All the northern specimens differ from the southern ones, typical 

 eJegantula, in the entirely black prescutum. Specimens of obliquata 

 determined by MacGilHvray have been compared with the type of 

 oregana and no differences of importance could be foimd. 



Subfamilr :mes5i:n",e. 

 NEOPOPPIA, new genus. 



Belongs to Phyllotomini Rohwer. In Genera Insectorum Neopoppia 

 runs to Poppia Konow, but differs from the descriptions of that genus 

 in the deeply emarginate clypeus, the lateral ocelli being well below 

 the supraorbital line, and the different venation of the hind wings. 

 The genus Poppia Konow is known only through descriptions, but 

 judging from these it probably belongs to the tribe Phyllotomini 

 Rohwer. 



Head transverse, posterior orbits narrow; eyes large, converging 

 to the clypeus; malar space wanting; clypeus deeply emarginate; 

 antennae 9-jointed, pedicellum longer than the scape and.much longer 

 than wide, third joint longer than the fourth, basal joints hairy; 

 thorax similar to Caliroa but rather more elongate; propodeal spiracle 

 round and ocx^upying the same position as in Caliroa; basitarsi III 

 subequal in length with the following joints; claws with an erect 

 inner tooth; wings differ from those of Eriocarapoides varipes as 

 figured by MacGiUivray ^ in the transverse radius being interstitial 

 with the second transverse cubitus, the basal vein not so strongly 

 curved and more basad of the cubitus, and a few minor points.
