sides more or less converging from base to apex, evenly and more or 

 less moderately arcuate and finely beaded; base more or less arcuate 

 to truncate and finely margined, two-fifths to one-half wider than 

 the apex; apical angles subacute and more or less prominent an- 

 teriorly; basal angles obtuse and not rounded. 



Pi'opleiira' more or less convex, obsoletely punctulate and more or 

 less rugulose. 



Elytra oval, and more or less inflated; l>ase truncate to slightly 

 emarginate and scarcely wider than the contiguous prothoracic base; 

 humeri obtuse and not in the least rounded to subacute, not promi- 

 nent anteriorly; sides evenly arcuate, apex obtuse and not produced; 

 disc very strongly convex and without any semblance of even an ob- 

 tuse margin, more or less suddenly and arcuately or vertically de- 

 clivous posteriorly ; striato-punctate, the punctures, small to moderate 

 in size and arranged in rather distant series, or more frequently the 

 punctures are sunken within larger dents that vary in size in the 

 same series, the punctures may be rather evenly and closely to irregu- 

 larly spaced in each series, the intervals are finely, irregularly, and 

 rather thickly punctulate; the dents are usually larger at the sides, 

 scarcely denser, and not evident on the apex. 



Epiplevra' more strongly widened at base and moderately narrow, 

 gradually narrowing to apex; surface obsoletely punctulate. 



Sterna more or less punctate and rugulose.

Abdomen feebly shining, feebly punctate and more or less obso- 

 letely rugulose. punctures denser on the last segment, intercoxal

 ora acutely or obtusely dentate: anterior tibial spurs acute and 

 unequal, the anterior longer and very slightly thicker. Anterior and

 thickened and clothed in apical half beneath with a dense oval pad 

 of pubescence similar to those of the anterior tarsi.
