Male. — Strongly shining, brownish black, usually reddish on basal 

 half of pronotum and elytra, sometimes entirely reddish; antennae, 

 palpi, and body beneath brownish yellow. 



Head slightly convex, sparsely, finely punctate and indistinctly 

 pubescent on front, with a few long, erect hairs near eyes, densely, 

 finely granulose and with fine, longitudinal, parallel costae on occiput ; 

 clypeus triangularly depressed at middle along anterior margin, 

 smooth and impunctate along posterior margin, sparsely punctate 

 along anterior margin, densely, finely punctate and densely clothed 

 with short, erect hairs on median part; clypeal suture distinct, bi- 

 arcuate, deeply depressed at middle. 



Pronotum distinctly wider than long, widest at basal third; sides 

 broadly rounded posteriorly, strongly converging anteriorly, with a 

 large, unciform tooth at apical angles; posterior angles rectangular; 

 lateral margins sinuate near base ; surface glabrous, smooth and indis- 

 tinctly punctate at sides and on basal half, densely, irregularly dentate 

 on apical half, the teeth broad, semierect, variable in size, and rasp- 

 like, with four or five larger teeth on each side toward lateral margin. 



Elytra at base subequal in width to pronotum at basal third ; sides 

 nearly parallel, conjointly broadly rounded at apices, the margins 

 sinuate, slightly thickened and elevated at sutural angles; surface 

 glabrous, sparsely, finely punctate on disk, more coarsely punctate on
