This species has a peculiar facies o^\'i^g to the shortness of the niandiljles, 

 and the consequent bluntness of the muzzle, so diffeieiit frdiu the usual 

 aspect of Colpodes. The maxilliB project far beyond the mandibles, and the 

 apical joint of the palpi is fusiform. Tlie thorax is similar in tbrni to that 

 of many Pterostichi, but presents the singular feature of a rounded bladder- 

 like elevation near each posterior angle, — the metathoracic episterna are 

 very shoit.

Very similar to ('. imstulosus, V)ut longer and slenderer in all its paits ; 

 differing specifically, besides, in the presence of a well-marked basal plica on 

 tlie elytra. The mandibles in C. jnistulosus pixject very little beyond tlie 

 labi'um, scarcely the labrum's length ; in C. rotundiceps they project about 

 \h the length of the labrum ; the maxilla project far beyond the mandibles 

 in l)oth species. The usual tumid enlargement Ijehind the ej^es is elongated, 

 liut gradually narrows to the neck which has a faint constriction. The 

 thorax is very much narrower and resembles in form that of G. piceolus 

 (Chaudoir). 



24. G. Pichinchcc, n. sp. 



Hab. Pichincha, second camp (15,000 feet). Three examples. 



G. pustuloso proxime affinis, differt capite antice mandibulisque longior- 

 ibus fere sicut in Golpodes normalibus, collo angustiori supra perparum 

 depresso, oculis proniinentibus capite post oculos tumido rotundatim angus- 

 tato. Castaneo - rufus ; thorace suljcoi'dato-(|uadrato, postice valde sinuato,
