vex, minutely punctured, ami finely transversely corrugated ; dull testaceous 

 with thesutural and lateral edges and apical third, dusky ; beneath black, whitish, 

 sericeous : feet rufous or rufo- testaceous ; tarsi simple, slender, with the basal 

 joint of anterior pair as long as the two preceding united ; posterior femoral 

 plates lanceolate. This species is also very equivocal as respects its generic 

 characters. It is common and probably already described.
