Of this insect we have received ten specimens, some of which are in very good 
condition. The common, post-median, brownish, sutural patch on the elytra is 
bordered externally with a blackish line, formed by the numerous dark sete clustered 
at this place. The pair from Ventanas, and a male from Duenas (length 33 millim.), 
are smaller and narrower than the rest, and they may belong to a different species. 
COLLABISMODES, gen. nov. 
Rostrum very short, scarcely so long as the prothorax, curved, and exceedingly stout in both sexes, the 
antenne inserted at about the middle, the club stout, oblong-ovate; eyes large, transverse, coarsely 
facetted, and rather narrowly separated ; femora linear, unarmed; tarsal claws connate at the base; 
metathoracic episterna very narrow; the other characters as in Collubismus. 
The single species referred to this genus is a common insect in Central America.
