AWiedi to A. ornaUpenne (Perroud) from Guadeloupe; 
but differing in the sculpture and apical armature of the 
elytra_, besides the less regular arrangement of vittm on 
the latter. According to Perroud^s description^ the 
elytra are tres faiblement tronquees a leur extremite/^ 
whereas A. hirsutulum has the apex of each prolonged 
into an acute toothy distinct enough, but not spiniform, 
as in A. surinamum. The pubescence is very coarse 
and decumbent on the body, but the elytra have besides 
erect setse springing from the few acute granules on their 
surface.

Although a true Coccoderus, this species differs from 
the definition of the genus given by Lacordaire, in noc 
having the 3-5 joints of the antennm spinose at the apex. 
It seems to approach nearest G. hisignatus, of Buquet, 
which, however, has only one ivory-like spot on each 
elytron. It differs from G. sexmaculatus of the saoie 
author, in the coarsely sculptured thorax.
