DIPTERA 
femora compressed; tibiae with spurs, the fore pair without, the middle and hind pair each with two 
ranges of delicate lateral setse. Wings oval, longer than the abdomen, microscopic setulose. The costa 
produced beyond the tip of the radial sector, ending before the tip of the wing ; the subcostal vein is 
shorter than the humeral crossvein and ends free; Rj ends a little distad of the middle of the wing; the 
radial sector arises at about one-third the wing length from the base; the R-M crossvein is long, 
longitudinal in position, forming apparently the beginning of the radial sector; both media and cubitus 
are simple; anal vein wanting (PI, 4, Fig. 20).

Characters. — Head flattened, placed rather high as regards the thorax; face and front broad, 
the antennae situated high up, directed upwards and forwards; composed of sixteen joints closely united, 
the basal joints a little differentiated from those of the flagellum. Three ocelli of nearly equal size, 
situated near the vertex, in a gently curved line, the lateral ones about as far from the inner borders of 
the eyes as from the middle one. Palpi composed of three joints, elongate, the terminal joint slender and 
directed angularly backwards. Dorsum of thorax moderately convex; scutellum with short bristles. 
Abdomen slender, flattened cylindrical. Femora stout, flattened; front and middle tibiae with one, the 
hind tibiae with two spurs ; hind tibiae and metatarsi with a row of short bristles on the outer side ; all the 
tibiae without long bristles; coxae elongate. Wings longer than the abdomen; the subcostal vein rudi- 
mentary; Ri terminates before the middle of the wing; the radial sector not furcate; media wanting 
except the distal portion of its branches; cubitus furcate near the basal portion of the wing; the costa 
extends a considerable distance beyond the termination of the radial sector (PI. 4, Fig. 2 I ).

The slightly greater length of Rj, and other trifling differences given in the description of Cerato- 
scarcely warrant giving this form generic rank.
