16 TRAVELS AMONGST THE GREAT ANDES. 



late obtusis, basi vitrinque depressis plicaque obsoleta, sii1)tilissime striatis, 

 interstitio tertio 3-punctato, puncto priino prope basin alteris duobus longe 

 post medium. 



Long. 7 1 millim. ^ 5 . 



Closely allied to C. pustulosus, having similar short antennse, feebly 

 emarginated posterior tarsi, depressed base of each elytron, etc. ; but differing 

 in the shape of the head and the more oblong elytra. The thorax is similar, 

 but narrower and more elongated, and the rounded pustiile-like elevation 

 near the posterior angle is reduced to a simple convexity, without distinct 

 rounded outline. The claw joint of the tarsi has beneath a few very short 

 bristles. 



25. C. orthomus, Chaudoir, Ann. Soc. Ent. Fr., 1878, p. 289. 



Hab. Hacienda of Antisana (13,300 feet), Cayambe (12-15,000 feet). 

 Ten examples. 



In Chaudoir's description, dra-«ii from a single specimen, the sides of the 

 thorax are said to be " presque droits " ; they are nearly straight in some 

 examples but distinctly sinuated in others, the general form however being 

 always trapezoidal, as Chaudoir indicates. The thorax is relatively very 

 lar<>e, and the elytra short in this species, which resembles a short Calathus 

 rather than a Colpodes. Chaudoir speaks of the scutellar striole as effaced, a 

 term not strictly apidicable as there exists a short rudiment. The base of 

 the thorax between the smooth fovea and the angle has a convexity resembling 

 the more pronounced ]Dustular elevation of G. pustulosus. 



26. C. Altar crisis, n. sp. 



Hab. Valley of Collanes, Altar (12,500 feet). Four examples. 

 Augustus, niger vix nitidus ; antennis lirevibus ; capite parvo, collo per- 

 parum constricto : thorace subovato, postice paullo 

 angustato, angulis posticis rotundatis, nullis : elytris 

 apice minus late rotundatis nee sinuatis ^ $ aluta-"" 

 ceis, subtiliter striatis interstitio tertio 3-punctato : 

 tarsis subtus sparsim setosis articulo 4*° modice

Long. 7|-8l millim. ^ $ . 



Resembles certain slen<ler species of the genus 



Agomim. The head is normal, with rather pro- 



coLPODEs ALTARENsis, BATES, mineut eycs, and neck scarcely constricted. The 



*'"^*''' terminal joint of the palpi is fusiform. The legs 



and antenna; are relatively short and stout. The metathoracic episterna 



ar(> very short.
