depressed at the base, broader but hardly longer than the first and 



third. 



Black ; the mandibles and the tarsi ferruginous brown. Wings 

 hyaline, iridescent ; nervures black. 



The first recurrent nervure is received by the first cubital cell a 

 little before two-thirds from the base, the second at the extreme 

 base of the second cubital cell. The second cubital cell is extremely 

 small, almost pointed on the radial nervure, and not more than 

 one-sixth of the length of the first cubital cell on the cubital 

 nervure. On one side of the type specimen the second transverse 

 cubital nervure is absent, leaving the cell open. 



Length 4 mm.

 apical margin, nearly twice as broad at the apex as long, thinly 

 clothed with pale fulvous pubescence. Antennse inserted just 

 above the base of the clypeus, a little f ui-ther from each other than 

 from the eyes, as long as the thorax and median segment 

 combined ; the apical joints not at all thickened ; the second joint 

 of the flagellum longer than the third joint or than the scape. 

 Eyes rather deeply emarginate, convergent towards the vertex, 

 where they are separated by a distance equal to the length 

 of the second joint of the flagellum ; the posterior ocelli nearer to

 to the mesonotum, the front thinly clothed with short, pale, 

 golden pubescence. Pronotum short, strongly depressed and 

 clothed with pale golden pubescence. Thoi-ax and median 

 segment very delicately punctured. The median segment longer 

 than the mesonotum, strongly narrowed and depressed to the 

 apex, with a deep sulcus from the apex nearly reaching the middle, 

 the sides with thin greyish pubescence. Abdomen petiolate, 

 pubescent ; the first segment twice as broad at the apex as at the 

 base, half as long again as the second segment, the third segment
