with a fringe of black. bristles on posterior orbit. Antennae 
reddish yellow, 3rd joint very large, conical, with long yellow 
miscroscopically pubescent arista. Palpi reddish yellow, large, 
with six black spines. Proboscis reddish yellow. 
Thorax.—Black, very slightly shining, minutely pubescent ; 
shoulders and posterior corners at the edges narrowly tawny or 
yellow. Two humeral bristles, one post-humeral, two or three 
stiff ones on lower anterior corner of thorax; a pair of dorso- 
central, wide apart, a few on lateral margins, a strong one on each 
posterior corner of dorsum; and four on hind margin of scutellum, 
the outer pair placed towards the base. 
Abdomen.—Wholly black, minutely pubescent ; belly similar, 
genitals small, yellowish. 
Legs.—Coxae and femora black, more or less yellowish at their 
juncture; tibiae and tarsi mainly yellowish, former (especially the 
hind pair) with a blackish tinge. Legs microscopically pubescent. 
Wings.—Pale brownish yellow; viewed in certain directions 
vitreous and highly iridescent. Costa with minute spines as far 
as tip of 3rd vein, which is forked near its tip, which itself barely 
reaches beyond the middle of the wing. First discal vein very 
faint at base, rather strongly curved upwards, meeting anterior 
margin at upper corner of the rather squared wing tip ; pad discal 
vein straight, ending at lower distal corner of wing; 3rd and 4th 
discal veins gently bisinuate. 
Halteres, stem yellowish, clubs blackish. 
Described from a few 2 2 in my collection (including type) 
from Namunukuli, Ceylon, February 1910 [Green].

A Scutellum with four distinct bristles. (in 
ferruginea outer pair always weaker, 
sometimes very considerably so). 
B Abdomen with first three segments black, 
the remainder yellow... . apicalis, Brues. 
BB Abdomen mainly blackish or quite black : 
except in ferruginea which has it 
generally reddish or brownish yellow 
with an admixture of black of varying 
degree, sometimes to the extent of 
the whole surface.! 
C Only two proclinate bristles . tibvalis, Brues. 
CC Four proclinate bristles (the lower pair 
often weak in ferruginea).

the middle of the wing: rst longi-
