gently arched, and pretty densely clothed with minute bristles; the 

 three ocelli visible slightly luteous; antennæ with the third joint 

 rather large, somewhat roiinded; thorax broad, flat, rather broader 

 than the head, angles tolerably rounded, disk shining (in appearance 

 suggesting a small Sphaerocera)^ beset with very minute bristles, 

 which become rather scarcer towards the hinder part; scutellum rather

narrower and shorter than the thorax (again suggestive of Sphaero- 

 cera)\ each segment after the second successively narrower, the last 

 one being almost triangular; the third segment is very short, con- 

 tracted under the second; the hind margins form a curve convex 

 towards the thorax, the first segment being slightly emarginate in 

 the middle; the sixth (last) is much the longest. Legs stoutish, blackish, 

 basal two thirds of hind femora yellowish; middle tibiæ with two 

 small spines at the tip. Wings considerably overlapping the abdomen, 

 yellowish hyaline, darker about the basal half of the costa, blunt at 

 the tip, cubital vein extending about half the length of the wing, and 

 the costa slightly ciliate up to its end, subcostal vein running parallel 

 to it and ending just before it; both veins a little thickened at their 

 ends; first veinlet curved S-like, considerably at its base, slightly 

 at its end, vanishing distinctly before the tip of the wing; second
