Of shorter and less cylindrical form than J:, siirinamum : 

 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 ; antennae, legs, and side-pieces 

 of the sterna black. Head very coarsely rugose, thorax 

 minutely rugose, and with scattered elevated granules ; 

 el^'tra 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.
