Exocentrus is a well-known genus of wide distribution, and 
comprising a number of small Lamiaires, of ovate or oblong form 
of body with thorax armed on each side with a distinct acute spine. 
The antennse are not much longer than the body in the most slen- 
der species, and are generally setose ; the basal joint is of moderate 
length, forming an elongate club thickened almost from the base. 
The claw-joints of the tarsi are elongated but slender, and the 
claws are widely divergent. The genus may be known from all 
the genera of Acanthoeinitse by the sockets of the anterior thighs 
being open or angulated on their outer edges,
