wing bright yellow and bristly. Some strong and very long black 
bristles on posterior corners of dorsum, and two or three (or there- 
abouts) before the wing. Scutellum dull reddish brown with 
sparse depressed short yellow hairs, erect short black hairs, and a 
row of black bristles along hind border. 
Abdomen black, with uniformly distributed short black hairs, 
3rd, 6th and 7th segments each with a band of dirty white small 
scales occupying the greater part of their dorsal surfaces, the bands 
on the 6th and 7th segments less conspicuous. Sides of Ist and 2nd 
segments with long scale like yellow hairs. Belly blackish with 
yellowish pubescence, the basal part a little paler with whitish 
hairs. 
Legs.—Coxae black, femora brownish yellow, hind pair black- 
ish towards tips; tibiae a little darker brown, hind tibiae and all 
tarsi black. The whole of the legs with minute sparse black 
bristles and microscopic pubescence. 
Wings dark grey, the anterior half (about), except at tips, 
moderately dark blackish brown, the colour insensibly dying away 
along the veins behind the middle of the wing. Halteres yellowish.

Notes on the Exoprosopa vitrea, Big., group. 
At the time of publishing my revision of the Oriental species 
of this family (Jan. 1909), FE. vitvea, Big., was the only species of 
the genus in the Fast with absolutely hyaline wings. However, 
a careful study of a number of specimens has led me to believe 
that either there are two or three closely allied species, or else 
vitrea is very variable. One form is therefore set up as a good 
species, with a certain amount of reservation. The points of 
difference between my interpretation of witrea, my new species, 
and a third form, as they appear to me at present, are as follows :— 
1. E, vitrea, Big. (1) Antennae black, reddish at base: 
(2) wings brownish yellow on anterior part, costal 
cell generally concolorous, but exceptions with prac- 
tically clear wings occur: (3) yellowish hair on 
anterior part of thorax!: (4) scutellum practically, 
always wholly red: (5) sides of abdomen distinctly 
reddish or reddish brown, the colour varying in 
intensity and extent, spreading over more or less of 
the first four segments,” but exceptions occur in 
which no reddish colour can be perceived. 
2. E. vitripennis, sp. nov. (1) Antennae wholly reddish 
brown: (2) wings wholly clear: (3) whitish grey 
1 This applies really to the whole thorax, but, although specimens are fre- 
quently more or less denuded of pubescence there is in most cases sufficient left 
along the anterior margin to decide its colour. 
» Bigot said “ first two ’’ segments, but this is a character likely to be found 
a variable one.
