Loug. 16 mm. 



$ . Head arid thorax closely and rather strongly punctured, 

 median segment rugosely punctured, all rather thickly clothed with 

 long white pubescence ; abdomen finely and more sparsely punctured, 

 thinly clothed with much shorter pubescence. Clypeus broad, the 

 anterior margin almost straight ; eyes widely but distinctly emar- 

 ginate. Antennae stout, of about equal thickness throughout, a little 

 longer than the head, thorax and median segment combined. Prono- 

 turn no longer than the scutellum, the anterior margin straight and 

 distinctly raised. Scutellum subcarinate longitudinally ; median 

 segment steeply sloped posteriorly. Abdominal segments broad, the 

 petiole short, first segment rounded at the base, segments 2-6 slightly 

 constricted at the base ; the apical incision of the seventh dorsal 

 segment large, nearly as broad at the apex as deep, the lateral 

 processes of the incision narrow and pointed, flattened above, the apex 

 smooth, the base rather deeply grooved longitudinally. Second abscissa 

 of the radius longer than the third ; first recurrent nervure received 

 beyond two-thirds from the base of the second cubital cell ; second 

 beyond one-third from the base of the third cubital cell, curved out- 

 ward in the middle ; second transverse cubital uervure almost straight.

This approaches more nearly to the male of rvfifrons than to any 

 other described species, but has distinctly longer antennae, a shorter 

 clypeus, and a somewhat broader and shorter abdomen ; the colour of 

 the clypeus and anterior margin of the prouotum is different, and the 

 yellow abdominal bauds narrower. The apical joint of the flagellum 

 is blunt at the apex, not distinctly truncate as in rufifrons. The 

 position of the second recurrent uervure is also different.
