 The antennas in this species are broad black and nearly paral- 

 leled-sided, the second and third joints being perhaps a shade 

 wider than the others. The head is rounded behind the eyes. 

 The thorax is oblong, coarsely punctured on the disc, rounded on 

 the sides near the front, and canaliculate in the centre of the 

 median line. The elytra are rather broad and depressed, punctate, 

 fulvo-pilose, as long as the body, and subtruncate or very broadly 

 rounded at the apex.
