Broad, flat, shining; frons very broad, the eyes 
scarcely occupying each one-sixth the width of the 
head ; it is moderately shining, gently arched, and 
pretty densely clothed with minute bristles ; the three 
ocelli visible slightly luteous ; antenne with the third 
joint rather large, somewhat rounded ; thorax broad, 
flat, rather broader than the head, angles tolerably 
rounded, disk shining (in appearance suggesting a small 
Spherocera), beset with very minute bristles, which be- 
come rather scarcer towards the hinder part ; scutellum 
rather dull, margined, nearly four times as broad as 
long: abdomen black, narrower and shorter than the 
thorax (again suggestive of Spharocera) ; each segment 
after the second successively narrower, the last one be- 
ing almost triangular; the third segment is very short, 
contracted under the second ; the hind margins form a 
curved convex towards the thorax, the first segment be- 
ing slightly emarginate in the middle; the sixth (last) 
is much the longest. Legs stoutish, blackish, basal two- 
thirds of hind femora yellowish; middle tibie with 
two small spines at the tip. Wings considerably over- 
lapping 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 run- 
ning 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, vanish- 
ing distinctly before the tip of the wing ; second veinlet 
also S-like, diverging at its end from the first, and end- 
ing distinctly below the tip of the wing; third veinlet
