Long. lin. 
Of shorter and less cylindrical form than surinamum : 
thorax shorter, more rounded on the sides, and attenuate 
from the middle to the base. Clothed with a moderate 
tawny pubescence, sub-erect on the elytra and legs ; colour 
red, varied with black patches, elytra yellower and 
shining, thorax opaque ; antennse, legs, and side-pieces 
of the sterna black. Head very coarsely rugose, thorax 
minutely rugose, and with scattered elevated granules ; 
elytra punctured, more coarsely and densely so near the 
base. The black marks on the thorax are on the disc, 
and consist of a lateral vitta expanding on the front 
margin, and two central vittae extending only from base 
to middle, and there united by a cross belt; but these 
marks are sometimes more or less blended. On the 
elytra the base is spotted with black, and there is a 
squarish black spot in the scutellar region, an oblique 
stripe from the shoulder, a triangular discal patch behind 
the middle, and a spot at the apex, including the apical 
spine.
