brevi, convexissimo, antice abrupte truncato, in medio profunde impresso ; 

 elytris convexis, obsolete coriaceis angusteque striatis : 



Long. 12-13, lat. 8-9 mm . 



Black, moderately shining, very convex, head granulose, very 

 broad, with the margins of the clypeus reflexed, indented in the centre 

 with the two augles raised and a conical very short horn between the 

 eyes ; prothorax very convex, shagreened, abruptly truncated in the 

 anterior part which has a broad central depression culminating in the 

 centre of the disk where it forms two obsolete protuberances ; elytra 

 as broad as the prothorax at the base and more convex, vaguely 

 shagreened with narrow shining striae ; anterior tibiae tri-dentate ; 

 underside black with a short rufous villosity ; club of antennae 

 reddish-brown. 



Female, like the male, but with a rudimentary cephalic horn and 

 without any impression on the anterior part of the prothorax. 



Owing to its convexity the facies of this species is not unlike that 

 of Macroderes Greeni.
