Wings blackish brown, hyaline at tip and along posterior margin, the pale 
portion of wings limited by the tip of 2nd longitudinal vein and not quite reach 
ing the apex of anal cell ; 1st posterior and anal cells open ; alula with a fringe 
of whitish scales ; halteres brownish. 
9 Similar ; frons a little wider. 
Length 16-18 mm. 
Described from 4 specimens in good condition from Quetta. 
Nearest to E. pennipes Wied, from which it differs in the antennae being 
mainly dark red, the patches of snow-white scales at sides of 1st abdominal 
segment, and the more extended clear portion of the wing margin. The dark 
portion of the wdng has in the present species a more brownish tinge than in 
pennipes ; in one of my specimens there are somewhat lighter portions in the 
2nd basal, discal, and anal cells. 
The specimen from Karachi mentioned by Brunetti on p. 198 of Vol. I, Diptera 
Brachycera, evidently belongs to this species. 
Exoprosopa evanescens. Becker. 
Pei-sische Dipteren, Ann. Mus. Zool. St. Petersburg, 1912, p. 559. 
I have eight specimens from Quetta which exactly correspond with Becker’s 
description. 
Head, including 1st two antennal joints, scuteUum, apical portions of all ab- 
donrinal segments, coxae, femora, and tibiae, red ; 3rd antennal joint, dorsum of 
thorax, bases of abdominal segments, and tarsi, black or blackish. Head and 
thorax covered with pale yellow scales, abdomen with grey scales. Wings lightly 
infuscated, apical and posterior margins nearly clear, all cross veins darkened ; 
the 1st posterior cell is crossed near its centre by a transverse vein ( “ mit ciner 
iiberzahligen Querader ”). The latter character is uncommon in the genus 
Exoprosopa, though it occm-s in E. singularis Macq., and a few other species. 
In Becker’s type the 3rd antennal joint was broken off ; all my specimens have 
this joint black, rather long and slender, with the style, w'hich is about ^ the length 
of ioint, testaceous. 
Exoprosopa gujaratica, n. sp. 
^ Head dull red, with short greyish pubescence, intermixed on frons with short, 
stiff, black hairs ; frons at vertex about the width of head, at antennae about 
^ ; proboscis black ; 1st antennal joint j’^ellow, hairy ; second black at base, with 
apex yellow ; 3rd black on blackish, style thick, about ^ the length of 3rd joint. 
Thorax black above, rufescent below, with short but thick greyish-yellow 
pubescence ; pronotum and sides with longer light yellow hairs ; bristles irear 
base of wings and on postalar calli black ; scuteUum reddish brown towards 
apex covered with pubescence similar to that on thorax, with black marginal 
bristles. 
Abdomen broadly blackish above, but red at sides and on apices of segments, 
pubescence concolorous with that on thorax, no black hairs at sides or at apex. 
Legs red; coxae, tips of fore femora and tibiae darkened, aU tarsi black ; femora 
and tibiae sparsely covered with greyish scales ; intermediate tibiae and posterior 
femora and tibiae mth the usual spinules. 
Wings rather dark brown, with a narrow border, lighter but not hyaline, ex- 
tending from the point where 1st longitudinal vein joins the costa rather 
irregularly to the anal margin ; halteres yeUow. 
9 Similar ; vertex slightly broader, 
length 8-12 mm. 
Described from six ^ and 2 9 9 from Deesa, all taken in October. 
This species is nearest to E. lateralis Brun, from which it differs in its smaller 
size, the absence of any black hairs on abdomen, and the extent of the lighter 
margin of the wings. In the present species the lighter portion is much narrower 
than in lateralis, amA less weU defined ; there is no lighter indentation running into
