Head about twice as wide as long, scarcely convex between the 

 eyes, very feebly impressed laterally, punctures rather fine, some- 

 what densely placed and quite evenly distributed. Antennm long, 

 rather slender, outer three joints very feebly compressed and not 

 dilated, third joint scarcely as long as the next two combined, fourth 

 just noticeably longer than the fifth, the latter, sixth, and seventh 

 subequal in length, eighth just the least shorter, slightly wider and 

 subtriangular, ninth and tenth suborbicular, eleventh irregularly 

 short-ovate. 



Pronotum somewhat transversely oval, about a third wider than 

 long ; disc moderately and evenly convex, rather coarsely and densely 

 punctate, the punctures crowded and granular laterally ; apex scarcely 

 emarginate and more or less obsoletely beaded; sides rather strongly 

 rounded, scarcely briefly sinuate before the basal angles and finely 

 beaded ; hase truncate to feebly arcuate, obsoletely margined, about a 

 seventh wider than the apex and quite equal to the length; apical 

 angles distinct and subacute, not in the least prominent anteriorly; 

 basal angles obtuse. 



Propleurce rather densely punctate and rugulose. 



Elytra oval, about a half wider than the thorax, widest at the 

 middle ; hase truncate ; humeri very obtuse and rounded ; sides evenly 

 arcuate, apex rather narrowly rounded; disc very feebly convex, 

 typically depressed, rather suddenly and somewhat narrowly rounded 

 laterally and inflexed, dorsum frequently more strongly convex, 

 arcuately declivous posteriorly; surface muricato-granulately punc- 

 tate, punctures irregularly and quite densely placed, becoming dis- 

 tinctly granular and setigerous laterally and on apex, setae short and 

 inconspicuous, the granules are small and scarcely subseriately 

 arranged. 



Epifleura' moderate in width, gradually narrowing from base 

 to apex, superior margin quite straight beneath the humeri ; surface 

 more or less obsoletely punctate. 



Sterna rather densely punctate and more or less rugose. 



Parapleural rather densely but not strongly punctate. 



Abdomen more or less shining, quite evenly and not very densely 

 punctate, punctures denser on the fifth segment, the first more 

 strongly sculptured. 



Legs moderate in length and somewhat slender; anterior femora 

 mutic; anterior tibial spurs rather short and apparently subequal 

 in length and stoutness, and probably similar in the sexes; anterior 

 tarsi dissimilar in the sexes. 



3Iale. — Unknown to me. 



Female. — Body rather broadly ovate, antennae reaching a little 

 beyond the base of the prothorax. Elytra arcuately and more or
