 depressions elongate and shallow; disk uniformly convex, without costae or 

 discal foveae ; surface glabrous, finely, uniformly, but not very densely punctate, 

 intervals densely, finely granulose. 



Abdomen beneath sparsely, coarsely fossulate-punctate, sparsely clothed with 

 short, recumbent, inconspicuous hairs, without lateral callosities, intervals 

 densely granulose ; last visible sternite strongly, transversely sinuate at apex, 

 with an obsolete, submarginal ridge, lateral margins coarsely serrate ; eighth 

 tergite coarsely, sparsely punctate, vaguely emarginate at apex. Prosternum
