Head of ¢ smooth, with a few scattered punctures near the eye; 
mandibles of the same length as the head, acute at the apex, in 
the middle with a projecting lobe, the edge of which is crenulated ; 
the clypeus wider than in the 9, slightly emarginate; the pro- 
thorax is smooth, darker than the elytra, slightly convex, pos- 
terior angles rounded ; elytra smooth, zneous, with a row of 
minute punctures near the suture, and parallel with it an oblique 
yellow line near the apex; the femora of the four posterior legs 
on the underside with a small yellow patch; the anterior tibiz 
irregularly crenulated externally with four or five prominent 
tubercles ; the intermediate are armed with a small spine, the pos- 
terior unarmed. ‘The Q is broader and more convex than the ¢, 
the head is distinctly punctured, with two slight elevations on its 
surface; mandibles short and acute, with a distinct tooth in the 
middle; the prothorax is very smooth on the disc, distinctly 
punctured on the sides as well as upon the anterior and posterior 
margins, with the hinder angles rounded. Scutellum with a few 
scattered punctures ; elytra more convex than in the ¢, with the 
sides parallel, smooth in the centre, but punctured at the base, 
lateral margins and apex, and with a small, yellow, nearly round 
spot near the apex. The fore tibize are crenulated, with four or 
five small prominent tubercles, the four posterior are armed with 
a small spine near the centre, and as in the ¢ the four posterior 
femora have a small fulvous patch on the underside.
