Species of this genus have been described from South America, Cuba, Florida, and. 
Java. They are chiefly recognizable by the large subcontiguous eyes, the moderately 
long second joint of the funiculus, and the small narrow scutellum. The rostrum in 
some of them is as long as the body, at least in the female, and is often thickened 
towards the base. The tarsal claws are either toothed or simple. ‘The males usually 
have the first ventral segment protuberant, lamellate, or bituberculate in the middle 
at the apex. Of the six Central-American representatives, five are treated as new; 
they may be grouped thus :—

anterior portion carinate. . . 6. «6 . . © + + «© « « « + antilope, Fabr.

Elongate, shining, nigro-piceous or black, the antenns, the basal half and apex of the femora, the tibie, and 
tarsi, more or less ferruginous ; the prothorax, the alternate interstices of the elytra, the under surface, 
and legs sparsely clothed with very long, erect, yellowish, bristly hairs. Head almost smooth, the eyes 
very narrowly separated above; rostrum feebly curved, as long as the body in the 9, a little shorter and 
more thickened towards the base in the ¢, longitudinally rugulose and shallowly sulcate in its basal half 
and almost smooth thence to the apex, the antennz in the 2 inserted a little before, and in the ¢ slightly 
beyond, the middle, joint 2 of the funiculus considerably longer than 3. Prothorax longer than broad, 
transversely globose anteriorly, narrow, depressed, and subcylindrical behind, and abruptly constricted in 
front; the globose portion coarsely, confluently punctate, and also carinate down the middle, the short 
basal portion also very coarsely punctate. Elytra moderately long, not or very little wider than the 
prothorax, subparallel in their basal half, constricted in front, the humeri rather prominent; the seriate 
punctures coarse and placed in shallow strie, the setigerous impressions minute. Meso- and metasternum
