Elongate, strongly shining, uniformly brownish black, sometimes 

 reddish on apical declivity, the antennae, palpi, and tarsi yellow- 

 ish brown. 



Head sparsely, finely punctate, densely granulose. and sparsely 

 clothed with short, recumbent, whitish hairs on clypeus and front of 

 head : clypeus shallowly. arcuately emarginate in front : clypeal suture 

 indicated at middle, obsolete at sides; labrum finely, densely punctate. 



Pronotum slightly longer than wide, widest at middle, deeply arcu- 

 ately emarginate in front ; sides broadly rounded, with a small, broad 

 tooth at apical angles: posterior angles broadly rounded: surface 

 sparsely clothed with short, recumbent and semierect. inconspicuous, 

 yellowish hairs, sparsely, finely punctate on basal half, densely, irregu- 

 larly dentate on apical half, the teeth broad, semierect. variable in size, 

 and rasplike. 



Elytra at base slightly narrower than pronotum at middle : sides 

 parallel, conjointly broadly rounded at apices: apical contour (when 

 viewed from above) broadly rounded: surface finely, shallowly. ru- 

 gosely punctate, the punctures liner and more obsolete on apical 

 declivity, sparsely, irregularly clothed with short, recumbent, yel- 

 lowish hairs; apical declivity broadly, shallowly depressed along 

 sutural margins: sutural margins on apical declivity not gibbose or 

 expanded laterally at middle, but broadly, uniformly elevated along 

 entire length, the sides not abruptly deflexed.
