[January, 



The male has a feeble lateral carina, as in the same sex in C. lateralis. 

 One specimen only bears a locality label, Colombia. 



C. lateralis Fairm. — Two males and one female from Colombia, and 

 one female labelled " Peru " {^ex coll. Fry), this latter locality requiring 

 confirmation. They agree in colour with Fairmaire's c? figure, except 

 that the elytra have one or two oblique, more or less distinct, testaceous 

 patches near the apex. 



C. traheatus Fairm. — Two males and six females, the former agreeing 

 with Fairmaire's 6 figure, one of the latter having the common black 

 post-median fascia of the elytra reduced to one or two small spots on 

 each wing-case (var. hijmnctatus. Pic, L'Echange, 1903, p. 108. — 

 Colombia and Venezuela. 



C. hremei Fainn. — Five males and six females, including two pairs 

 separately pinned. The elytral markings are very variable in both 

 sexes, one 5 having the testaceous patches reduced to a long lateral 

 stripe and a small subapieal spot (as in the insect named by Pic 

 C.fumatus, var. htteonotatns). The males have the prothorax and base 

 of the elytra thickly nigro-pilose, a character distinguishing C. hremei 

 from the same sex of C. liumeralis, sallei, and fiimatus. — Colombia and 

 Venezuela (Merida and Caracas). 



C. unicolor Fairm. — One female from Colombia, acquired in 1846. 

 The male is figured in Lacordaire's "Atlas" (pi. 45, fig. 5). 



C. liumeralis Fairm. — Four males and six females, the females 

 varying slightly in the development of the dark markings. The broad 

 dense tuft of long erect black hairs on the swollen portion of the disc of 

 the elytra before the middle is a remarkable $ character in this species 

 and in C. sallei. — Venezuela. 



C. sallei Fairm. — Six females from Venezuela must belong to this 

 species, as they have the elytra more constricted behind the middle than 

 in C. htimeralis, and are also differently coloured — nigro-cyaneous or 

 black, with three large patches on the disc (the post-basal one trans- 

 verse, the submedian transverse or subquadrate, and the subapieal 

 rounded), and a lateral stripe, testaceous. A series of eleven males from 

 the same country almost certainly belong here : seven of them have the 

 elytra maculate, much as in typical C. hremei, J (from which they 

 differ in having the elytra smoother and less metallic, and glabrous at 

 the base, and the prothorax more sparsely pilose) ; the other examples, 

 with the dark markings parti}' or almost entirel}' obsolete (except at the 

 base), are scarcely separable from the same sex of C. htimeralis and
