Long. 4-5 mm. 



cJ . Coarsely punctured, the alxlonien very finely and 

 closely punctured, uith large scattered punctures on the 

 basal segment and on the second ventral segment, dorsal 

 surface of the median segment as long as the scutellum, the 

 basal area irregularly obliquely striated. Clypeiis widely 

 emarginate at the apex, the angles of the emargination not 

 produced into distinct teeth. Ventral aljdominal segments 

 2— i M ith a fringe of long hairs at the apex, segments 3-5 

 ■with a s|)inc at the apical angle on each side, seventh dorsal 

 segment witli three apical teeth, the middle one blunt and 

 broad. The apical joint of the flagellum is rather strongly 

 curved and hollowed beneath, longer than the penultimate. 

 Second recurrent nervure received by the fiist cubital cell 

 very near the a[)ex ; second cubital cell small, with a short 

 petiole.

 March. 



This is near confertiis, but differs in the sculpture of the 

 median segment and the neuration.
