?. Galea short, broader than long. Clypeus very broadly 

 rounded at the apex, the front and clypeus clothed with 

 silver pubescence. Eyes separated on the vertex by a 

 distance slightly exceeding the length of the two basal 

 joints ot the flagellum. Thorax closely and minutely 

 punctured, clothed with short greyish hairs, with short 

 silver pubescence on the mesopleurse. Median segment 

 more than half as long again as the scutellurn, very minutely 

 punctured and clothed with short whitish hairs ; the posterior 

 slope with a deep longitudinal sulcus, which extends to the 

 apex of the dorsal surface. Second ventral segment sub- 

 opaque, very finely and closely punctured ; third and 

 following ventral segments shining, with a few scattered 

 punctures. Pygidial area longer than the basal breadth, 

 narrowly rounded at the apex. Basal joint of fore tarsus 

 with five spines. Radial cell narrowly rounded at the apex, 

 not reaching as near to the outer margin of the wing as the 

 apex of the third cubital cell; second and third abscissae 

 of the radius subequal.

$ . Galea scarcely longer than the scape, a little longer 

 than its basal breadth ; palpi not elongate. Head covered 

 with whitish hairs, changing to pale golden on the clypeus. 

 Vertex opaque, very finely punctured ; eyes separated on 

 the vertex by a distance scarcely equal to half the length of 

 the second joint of the flagellum. Antennas stout, the 

 joints not arcuate beneath. Thorax opaque, finely and 

 very closely punctured ; median segment twice as long as
