margin. Scutellum purplish. Elytra prominent at the shoulders, 
then gradually attenuated to near the apex, afterwards more 
quickly narrowed, apex truncated in a straight line, sutural angle 
simple, external angle produced into a short and acute tooth ; 
surface clothed with strong erect bristles, each proceeding from 
a puncture, dark purplish, with a silky gloss ; a small oblong spot 
on each side near the scutellum, and two larger, rounded, on the 
disk (one before, the other after, the middle) and a transverse 
spot at the apex sulphur-yellow. Body beneath blackish, clothed 
with grey pile and with 'an oblique stripe on each side of the

This very beautiful little species occurred sparingly at Ega, on 
slender branches of trees in the forest*.

This elegant species is readily distinguishable from all others
