 surface sparsely clothed with short, recumbent, reddish-brown hairs, 

 which are slightly longer on apical declivity, densely, coarsely, deeply 

 punctate on disk, finely, sparsely, indistinctly punctate on apical de- 

 clivity : apical declivity with sutural striae smooth and not depressed 

 on anterior part, the sutural margins narrowly elevated, armed near 

 top of declivity with two short, conical teeth, which are obtusely 

 rounded at apices and separated at bases, the lateral margins thickened 

 and strongly elevated, but without elevated tubercles at sutural angles ; 

 each elytron with a moderately elevated, obtuse tubercle behind mid-
