NEW AND LITTLE KNOWN INDIAN BOMDYLIID^.

narrower posteriorly, and hardly reaching hind margin of wing ; the infusca- 
tion is more pronounced round all the cross veins ; the discal cell has a small 
sub-hyaline spot near base, and another larger one near apex ; 1st posterior 
and anal cells open ; base of costa with some whitish scales and short black 
bristles ; halteres pale. 
$ Similar, except as follows : frons slightly narrower, covered with snow-white 
scales ; st3de of antennae longer, red ; occiput narrower ; abdomen red, 1st and 
2nd segments wdth broad basal triangular patches black ; genitalia fringed with 
soft red hairs. 
Length 13-14 mm. 
Described from 1 $ and 5 9 9 from Quetta, mostly in good condition. The 
(S however has the abdomen somewhat denuded and has lost one wing. 
This is very near to E. undans. Walk., of which the locality is unknown. It 
differs as follows : the bands of white scales on the abdomen are broader in the 
present species, and more distinct ; the ground colour of the abdomen is darker, 
at any rate in the 9 ; the neuration is similar, except that undans has a slight 
appendicular vein from lower corner of discal cell. The wing markings in the 
present species are very similar to those in undans, but they are darker, and all 
my specimens have the cross vein connecting the lower branch of the 2nd longi- 
tudinal vein with the 3rd infuscated, whereas this ocin is clear in undans. The 
type and only specimen of undans is headless, so comparison as regards the 
head is possible. 
Both Major Austen and Mr.CoUin, who happened to be at the British Museum 
when I was comparing my specimens with Walker’s type of undans, consider 
the present species distinct, otherwise I should have hesitated to describe it. 
Exoprosopa iridipenn'S, n. sp. 
$ Head with the eyes almost touching at vertex, but the frons at level of 
antennae quite ^ the width of head ; frons and face nearly to upper mouth edge 
black, becoming much lighter at mouth edge ; frons with thick black pubescence 
down to the antennae, and some purple scales both above and below antennae ; 
proboscis rather long, blackish ; palpi thin, covered with bristle-like hairs ; 
antennae black, 1st and 2nd joints thickly covered with long black hairs, 3rd 
joint bare, tapering, style about half as long as joint, with a minute terminal 
bristle ; occiput with short greyish pubescence, and some purple scales. 
Thorax black ; pronotum and sides thickly covered with rather long bright 
golden hairs ; dorsum covered with iridescent purplish blue, scales, and with 
patches of snow-white scaly hairs near wing base ; below there are patches of 
similar hairs on the sternopleurae, no conspicuous bristles at base of wings 
pr on postalar calli ; scutellum brownish, with some purple scales at base, and 
numerous rather short black bristles along its apical margin. 
Abdomen black, covered with highly iridescent purple-blue scales ; 1st segment 
with a patch of whitish hairs at sides ; 3rd segment with a large oval patch of 
snow-white depressed scales on each side, extending over the side margins, and 
indications of a much smaller patch of similar scales on extreme sides of 6th seg- 
ment ; remainder of the pubescence black, except that there is on the posterior 
margins of the last two segments an admixture of scaly white hairs ; venter with 
the ground colour black ; 2nd segment with a triangular patch of snow-white 
scales, the apex of the triangle being at apical margin ; 3rd segment almost en- 
tirely covered by similar scales, 4th with similar scales at apex ; the black part 
of the venter is, like the dorsal portion of abdomen, covered with iridescent 
purple blue scales. 
Legs black ; all coxae covered with rather long greyish pubescence ; intermediate 
and posterior femora and tibiae with very short spinules. 
Wings hyaline and highly iridescent ; yellowish at base and in costal and sub- 
costal cells; base of costa and all the nervures testaceous ; costa at base with very
