 head subquadrate, foveas shallow, anterior one larger than the others ; 

 antennae rather elongate, third to sixth joints elongate, seventh 

 much shorter, eighth quadrate, ninth larger, quadrate, tenth trape- 

 zoidal and larger, eleventh large, ovate, acuminate ; prothorax 

 larger than the head, rather elongate, oblique at base, lateral

 minute, base punctulate ; elytra somewhat elongate, slightly 

 attenuate at base and trifoveate, shoulders little pronounced, dorsal 

 stria nearly entire and slightly bisinuate ; abdomen shorter than the 

 elytra, carinulae extremely short. 



Male : Antennae more slender and longer than in the female ; 

 anterior tibiae slightly dilated in the middle inwardly and more or 

 less minutely tuberculate before the apex, intermediate ones slightly 

 sinuate inwardly and with a strong spur at tip, posterior ones 

 arcuate, all the femora thick ; metasternum strongly and broadly 

 impressed, minutely bituberculate close to the intermediate coxae ;
