a prominent, ventral bristle, the second segment with a 
dorsal seta and the third segment short, oval with rather 
blunt apex. The arista is slender, basally thickened and 
one and a half times as long as the third segment. Front 
with scanty, fine, erect pile which is rather short. Face 
without pile. The occiput concave and sunken, the poste- 
rior margin of the eye prominent for a short distance 
behind the head. Thorax : The thorax is a little longer 
than wide and rather strongly convex. It is relatively 
bare with a few, scattered, suberect, stiff hairs on the 
anterior half in front of the suture and similar, still more 
scanty pile behind. Scutellum rather large, convex with 
a few fine, erect hairs of the disc and 2 pairs of rather 
prominent, comparatively long, moderately stout, marginal 
bristles. Legs : The legs are slender, the hind femur 
quite slender with 4 ventral setae on the basal half and 
a double row of quite sharp, erect, spinous, non-tuberculate 
bristles placed ventrolaterally and ventromedially on the 
outer half of this femur. The outer row contains 4 ele- 
ments of about the same length and 3 smaller ones in- 
terspersed. The medial row contains 3 which are stout, 
and like the larger elements on the lateral portion. Hind 
tibia as long as the femur, quite slender with minute, 
fine, appressed, quite inconspicuous pile. Tarsi also slender, 
the basitarsus as long as the remaining segments, the 
second segment a little longer than the next 2, the third 
segment nearly twice as long as the fourth segment. 
Tarsal pile similar to that of the tibia, the ventral fringe 
quite short and also fine, and the apices with scarcely 
longer hairs, except on the ultimate segment, where there 
are 2 stiff, dorsal hairs side by side, which are nearly as 
long as this segment. Claws extremely fine, curved from 
the base and sharp, the pulvilli well developed. Middle 
femur with a posterior fringe of pile in which, however, 
the individual hairs are not very long. Apical bristles of 
the middle tibia are quite small and weak, middle basi- 
tarsus slightly longer than the next 2 segments, the other 
segments also progressively reduced. Anterior legs with 
extremely short, inconspicuous, fine, scanty pile, their 
basitarsus about as long as the next 2 segments and the
