Apparently a common insect in the States of Vera Cruz and Oaxaca, It is easily 
known from its allies by the transversely depressed inter-ocular portion of the head ; 
the prominent eyes; the long second joint to the funiculus; the basally truncate, 
closely punctured prothorax; the oblong, subtriangular, finely punctate-striate elytra, 
with rather convex interstices and prominent humeri; and the feebly unguiculate 
anterior tibie. The scales are uniformly coloured, usually pale green, sometimes bluish- 
or golden-green, rarely whitish or cinereous. In several exaniples the alternate elytral 
interstices are a little wider than the others, these specimens approaching &. carinirostris.

Not rare in the Mexican States of Oaxaca and Vera Cruz; the type is from the 
first-mentioned State. The general vestiture is whitish or pearly-white, sometimes 
greenish with the raised alternate elytral interstices and two vitte on the disc of the 
prothorax white, the head, rostrum, prothorax, and legs often tinged with cupreous or 
golden. ‘The sharply carinate rostrum, with the upper anterior portion Jess divergent 
on each side in front, the more numerous elytral strie, &c., readily distinguish this 
species from Compsus auricephalus. The antennal scape is slender at the base in the 
female. The elytra have the alternate interstices 2, 4,6, 8, and the basal portion of 8, 
widened and subcostate, and 8 bifurcate beyond the middle, the intervening space 
enclosing two short supplementary strie. The two examples ( ? ) from Guatemala have
