Black above, deep reddish brown beneath, and very smooth and 

 shining, elongate-oval in shape and not very convex. The head 

 is transversely rugose, except on the vertex, the clypeus armed 

 with two moderately distant reflexed teeth and divided from the 

 forehead by a slight carina interrupted in the middle. The pro- 

 notiim and scutellum are entirely smooth and shining, and the elytra 

 regularly and deeply punctate-striate, with the subsutural inter- 

 stice wide and irregularly punctured throughout its length ; the 

 apical margins are strongly and irregularly punctured. The 

 jiygidium is very deeply and coarsely, and more or less coufluently, 

 punctured. The lower surface is almost entirely smooth, but the 

 anterior angles of the melasternum are lightly punctured. 



S . The front tarsus is thick and the inner claw dilated into a 

 convex plate as broad at its extremity as it is long and very in- 

 conspicuously cleft. 



Length 15-17 mm. ; breadth 8-9 mm.

Black above, deep reddish brown beneath, very smooth and 

 shining, shortly ovate, rather broad behind, and moderately convex. 

 The head is rather closely rugose except between the eyes, where 

 it is smooth ; the clypeus is feebly bidentate in front and separated 

 from the forehead by a slight carina interrupted in the middle. 

 The pronotum has a few extremely minute punctures at the sides 

 only, and the sciiteUum is uupunctured. The elytra are very 

 strongly punctate-striate, the striae forming three pairs, and the 

 spaces between the pairs each contain a single row, or part of a 

 row, of punctures, the second interstice containing an irregular 

 aggregation ; the apical margins are irregularly punctured. The 

 stridulatory files of the p>ropygidium are moderately distant and 

 not very fine, and the jjygidium is strongly and densely punctured. 

 The lower surface is almost smooth.
