 black, the legs black and moderately metallic, head punctato- 

 scabrous, sparsely punctate basally, the clypeus densely sculptured, 

 rather more than twice as wide as long, with broadly rounded angles, 

 the edges rather broadly reflexed, except basally; antennal club not 

 quite as long as the stem; prothorax relatively small, two-thirds as 

 wide as the elytra, trapezoidal, very convex, smooth, finely, sparsely 

 punctate; elytra broad, parallel, with arcuate sides, slightly longer
