in the middle ; mesopleiirse without tubercles ; second ventral segment 

 without a raised area at the base ; pygidial area gradually narrowed from 

 the base, about three times as long as the greatest breadth and almost 

 pointed at the apex. The abdominal segments are not strongly constricted ; 

 the basal segment broader than long. Sparsely pixnctured, very finely on 

 the head and thorax, more coarsely, but shallovvly, on the median segment 

 and abdomen ; enclosed area at the base of the median segment smooth 

 and shining, with a few oblique striaa in the angles. First recurrent 

 nervure received at one-third from the base of the second cubital cell. 



Black ; mandibles, clypeus, front, checks, a spot on each side on the 

 vertex, pronotum, tegute, an irregular band on the mesopleurse 

 scutelhun, postscutellum, a large spot on each side of the median segment, 

 abdominal segments 1 — 5, very narrowly black at the base on the dorsal, 

 broadly testaceous brown at the base on the ventral surface, and the legs 

 bright yellow. Wings hyaline, slightly iridescent, with a fuscous cloud at 

 the apex, nervures fvTSCo-ferryginous. 



(^ . Clypeus as long as the greatest breadth, broadest in the middle 

 almost the whole surface occupied by a concave depression of an oval 

 shape, the apical margin transverse, armed with a small tooth at the apical 

 angles. Apical joint of the flagellum very slightly curved, not quite as 

 long as the penaltimate. Pygidial area less than half as long again as 

 broad, truncate at the apex, the sides almost parallel. 



Vertex and cheeks without yellow markings, median segment entirely 

 black, the thorax with the pronotum, tegulas and postsciitellum only 

 yellow ; femora marked with black.
