 tufts of pale fulvous pubescence and the floccus on the posterior 

 femora of the same colour, the tibiae and tarsi with short ferruginous 

 pubescence. Abdomen shining, the apical margins of the segments 

 broadly fulvo-testaceous, very bright, having a golden lustre.

 tured ; the face covered with short cinereous pubescence ; the clypeus 

 naked and much produced, the anterior margin and the tips of the

 Thorax : the sides of the metathorax, the floccus on the posterior 

 femora and the postscutellum with whitish pubescence, the latter 

 produced in the middle into a blunt tooth ; the legs fusco-ferrugi-
