1912.] E. BRuNETI1: New Oriental Diptera. 491 
Pipunculus brevis, mihi, sp. nov. 
2. Lower Burma. Long. 34 mm. (without ovipositor). 
Head.—Frons moderately wide, of uniform width up to the 
vertex, blackish seen from in front, silver grey seen from above; 
face similar; antennae brown, arista black. Back of head black- 
ish grey, only moderately produced hindwards. 
Thorax.—Almost uniformly blackish grey, ash-grey at sides, 
humeri small, brown. Scutellum dark brown,-bare, except for a 
few hairs on posterior border; metanotum ash-grey. 
Abdomen.—Blackish grey, shortened; sides of segments, and 
almost the whole of segments I and 2 grey tinged, which colour 
goes over the sides to the belly. The abdomen appears dis- 
coloured, and probably in its natural state it is wholly dark grey. 
The last segment bears a long shining brown horny process which 
reaches under the belly almost to the base of the abdomen. This 
process is turned slightly to the left. 
Legs.—Blackish brown; knees and base of tibiae light yellow- 
ish brown. 
Wings.—Very pale grey, nearly clear; stigma brown;’ anterior 
cross-vein placed rather after two-thirds of the distance from base 
of discal cell, but distinctly before its middle; 4th costal segment 
very shortened, not half as long as 3rd; 3rd and 4th together 
about equal to the 5th. The 4th longitudinal vein, after quitting 
the posterior cross-vein, takes an outward curve before proceeding 
to the wing border. Halteres brown. 
Described from I @ in the Indian Museum collection from 
Mergui, in good condition, except that, being gummed on cork, 
the underside cannot be properly examined.

tibiae with a broad blackish ring, occupying the middle third or 
more, tarsi yellowish brown.
