shining ; mesopleurae closely punctured. Scutellum narrowly 

 truncate at the apex. Median segment granulated, short, 

 abruptly truncate posteriorly, the surface of the truncation 

 punctured rugulose. Abdomen fusiform, shorter than the head 

 and thorax combined, shining and very minutely punctured ; 

 the seventh segment rounded at the apex, smooth ; the hypo- 

 pygium not prominent, simple, rounded at the apex. Third 

 cubital cell longer than the second on the radial nervure, 

 receiving the second recurrent nervure just before one-third 

 from the base. The division of the first cubital cell is not 

 marked. 



Black : the antennae, mandibles, prothorax, and legs ferru- 

 ginous; the apex of the clypeus pale yellow. "Wings hyaline; the 

 stigma ferruginous ; nervures pale testaceous, almost colourless.

c? . Clypeus convex, with a carina from the base not reaching 

 the apex, without a triangular truncation at the apex, closely 

 and microscopically punctured. Antennae shorter than the 

 thorax and median segment combined, inserted nearer to each 

 other than to the eyes, the apical joints slightly arcuate ; the 

 interantennal prominence V-shaped and touching the base of 

 the clypeus. Head shining, closely and not very finely punc- 

 tured, the posterior ocelli more than twice as far from the 

 eyes as from each other. Thorax rather more finely punctured 

 than the head, especially on the pronotum, which is almost 

 smooth, with the anterior margin raised. Scutellum nearly 

 triangular, narrowly rounded at the apex. Median segment 

 no longer than the pronotum, obliquely sloped posteriorly, finely 

 aciculate, closely punctured on the posterior slope. Abdomen 

 slightly fusiform, shorter than the head and thorax combined, 

 shining, minutely punctured, the apical segment rounded at the 

 extremity, the hypopygium rounded and ciliated, not projecting 

 beyond the dorsal plate. Claspers broad and short, the apex 

 with a fringe of long curved hairs. Second cubital cell a little 

 more than half as long as the third on the radial nervure. 



Black ; the anterior margin of the clypeus, two minute spots 

 between the antennae, the anterior margin of the pronotum 

 broadly interrupted in the middle, an oblique line on each side at 

 the posterior angle of the pronotum, and the spines of the tibiae 

 white. Wings hyaline, faintly iridescent, nervures black. 



Length 6 mm. 



$ . Head rectangular, nearly one-third as long again as broad, 

 slightly rounded at the posterior angles, smooth and shining ; the 

 eyes very small, ovate, not touching the base of the mandibles. 

 Thorax and median segment very sparsely punctured ; the pro- 

 notum a little shorter than the median segment, slightly 

 narrowed anteriorly ; scutellum nearly half as long as the
