Head densely pnnctiite, antenna' somewhat slender, ninth joint tri- 

 angulo-orbicular to transversely oval, tenth more or less transversely 

 oval. 



Pronot^tm subcordate to transversely suboval, widest near the mid- 

 dle, a fourth to scarcely a half wider than long; sides evenly and 

 quite strongly arcuate to basal seventh, or subangulate at middle, 

 rounded in front and quite rapidly converging posteriorly and sin- . 

 uate at basal fourth, thence in each instance quite straight and j^ar- 

 allel to the hasal angles; base equal to the length or in some males 

 shorter than the length; apical angles obtuse, frequently not in the 

 least rounded, at other times more or less so. 



Elytra quite broadly oval to siibquadrate, widest at or behind the 

 middle, a fourth to a third longer than wude; disc more or less 

 deplanate on the dorsum, strongly, arcuately, and vertically declivous 

 posteriorly; surface densely tuberculate, tubercles apparently ar- 

 ranged in rows on the dorsum or irregular throughout; each bears a 

 very short, black seta near apex; when arranged in rows there are 

 very small muricate punctures scattered sjDarsely and irregularly 

 between, always less distinct along the suture centrally; the tubercles 

 are more or less rounded and shining, the interstices l)etwoen more 

 or less opaque. Otherwise as in cordata.
