Champ., the elytra moderately eloupjate, more convex than in the allied 

 species, and with a dark streak on the suture before the apex. 



CoNOMORPHiNUs, n. gen. 



Head somewhat exserted, gradually narrowed behind the eyes, the latter 

 transverse, coarsely faeettei, depressed, lateral ; apical joint of maxillary palpi 

 stout, triangular; antennae short; prothorax transverse, imraarginate laterally, 

 truncate and margined at the base, and with a deep fovea on each side near 

 the hind angles; scutellnm triiaigular ; elytra elongate-oval, incompletely 

 covering the abdomen, confusedly punctate ; wings abbreviated, not reaching 

 the apex of the elytra ; anterior coxal cavities open behind ; legs short ; 

 tibiae with short, conspicuous spurs ; tarsi with the penultimate joint lobed, 

 the basal joint of the posterior pair shorter than the others united, the claws 

 angularly dilated at the base ; the other characters as in Conomorjphus. 



Type : C. bolivianus. 



The Bolivian insect forming the type of this genus might easily 

 be mistaken for a Tenebrionid allied to Helops, if the open coxal cavities, 

 etc., were not noticed.* It may be described as a broad Corwmorplms, 

 with a more exserted head, small, depressed eyes (as seen from above) , 

 a short prothorax, incompletely developed wings, and a short basal 

 joint to the posterior tarsi. The elytral puncturing is much finer than 

 that of the rest of the upper surface, an unusual character in this 

 group. The insect is probably of terrestrial habits and unable to fly. 



1. — Conomorphinus bolivianus, n. sp. 



? . Elongate-obovate, rather convex, flattened above, shining ; piceous, 

 the front of the head, the basal and apical margins of the prothorax, knees, and 

 tarsi ferruginous ; head and prothorax densely, moderately finely, the elytra 

 sparsely, minutely, punctate, finely pubescent. Head arcuately impressed 

 between the eyes ; antennae about reaching the base of the prothorax, rather 

 slender, joint 3 much longer than 4, 4-10 obconic, longer than broad, 11 longer 

 than 10. Prothorax considerably broader than long, as wide as the head, com- 

 pressed at the sides anteriorly, the latter feebly rounded towards the apex, the 

 hind angles sub-rectangular, the disc with two widely separated shallow foveae 

 at about the middle, the punctures here and there longitudinally confluent 

 and a little finer than those on the head. Elytra somewhat rounded at the 

 sides, narrowed towards the base and there much wider than the prothorax, 

 shallowly longitudinally grooved, the apices rounded. Beneath closely, finely, 

 the head and propleura coarsely, punctate. Length 7f , breadth 3 mm. 



Hah. : Bolivia, Territory of the Juracares Indians, N. side of 

 the Cordillera de Cochabamba (Bridges).
