discal cell. A series of both species seen side by side appear quite distinct. I 
have lateralis from Mount Abu and Matheran, but did not obtain it at Deesa. 
Exoprosopa insulata. Walk. 
There are several Indian species with wing markings somewhat similar to 
insulata. Walk., and I found four distinct species standing over that name in the 
British Museum viz., 
(a) insulata ; two specimens, including the type, from ‘‘ East Indies ” — • 
also a specimen from Assam. 
(b) a specimen from Dehra Dun, not good enough to describe. It has a 
pure white band at the base of 4th abdominal segment, and the 1st 
posterior cell just open. 
(c) Two specimens from Ceylon (Col. Yerbury), not in good condition. 
These have the 1st posterior cell closed. 
(d) A specimen from Madhapur, with the 1st posterior cell closed. This 
agrees with my specimens from Matheran, which I have described 
above as Exoprosopa siva. 
Brunetti probably had two or more species before him when he wrote the 
description of insulata on pp. 203-5 of Vol. I, Diptera Brachycera, though the 
figure of the wing on Plate III corresponds well with Walker’s type, and with 
my specimens. I therefore give below the points in which his description differs 
from the type. 
The proboscis does not project beyond the tip of antennae, but just beyond 
the upper mouth edge, (in my E. siva the proboscis projects well beyond the tip 
of antennae). I should describe the abdomen as follows : — 
Ground colour black, covered mainly with black scales ; 1st segment with a 
band of rather long yellowish brown erect hairs, 2nd segment with a complete 
basal band of pale yellow scales, 3rd and following segments with apical bands 
of similar but rather lighter scales, those on the 3rd and 4th segments the most 
conspicuous and extending over the side margins, on the other segments these 
bands are narrower and sometimes hardly noticeable ; the whole of the dorsal 
surface of abdomen thinly covered with fine long black sinuous hairs ; venter 
blackish, with black hairs, except on the 1st segment where the yellowish hairs 
extend well over the sides. 
The wings have the dark colouring extending over the basal half of the discal 
cell, and the basal | of the anal and axillary cells, and the spots are situated as 
follows : — One at the bifurcation of 2nd vein, being merely an extension of the 
baso-costal band ; one right across the vein closing the apex of discal cell, 
connected anteriorly with the dark portion of the wing ; free dark spots as follows : 
two larger ones, one near apex of upper branch of 2nd longitudinal vein, and one 
over cross vein connecting lower branch of same vein with 3rd longitudinal ; 
two smaller spots towards apex of lower branch of 2nd longitudinal vein, and 
one each near apex of 3rd, 4th, 5th and 6th veins, some of the latter being very 
faint; both the 1st posterior and anal cells are widely open; the discal cell is 
broad at apex, and has a small appendicular vein from its lower corner ; the lower 
vein of 2nd posterior cell meets the discal cross vein just below the middle, and 
has a slight appendix into discal cell ; halteres yellowish, base of the club dark. 
I have nine specimens, including both sexes, from Simla, which exactly agree 
with Walker’s type. 
E. bengaUnsis is quite distinct, but I have not seen a specimen of brahma. 
Exoprosopa abrogaia, n. sp. 
Head ; frons at level of antennae ^ the width of head, at vertex about 
half this width ; face and frons rufo-testaceous, covered with yellowish white 
scales, with a few short blackish hairs ; antennae red, 1st and 2nd joints with a 
few black hairs, 3rd joint rather short, gradually tapering,excluding style about 1|
