Exoprosopa fusccmotata, Becker. 
Persische Dipteren., Ann. Mus. Zool. St. Petersburg, 1912, p. 566. 
Head yellow or yellowish, antennse black ; thorax and scutellum blackish 
brown, ■with yellow and white scales and yellow bristles. Abdomen blackish 
brown, with white interrupted bands on the first four segments. Legs black ; 
wings greyish, marginal cell yellowish brown ; a brown suffusion at the posterior 
corner of discal cell ; 1st posterior cell closed at a right angle, and stalked. 
Length lOJ mm. 
The four specimens taken at Quetta agree well with Becker’s description. 
Exoprosopa siva, n. sp. 
d $ Head ; frons at level of antennae one-third the width of head, at vertex 
about one-sixth in both sexes; black, covered with pale golden yellow scales and 
black hairs, which are longest on the frons; occiput with short whitish pubescence : 
antennae black, 3rd joint rather short, being not much longer than the style ; 
1st and 2nd joints with black hairs, 3rd bare ; proboscis nearly twice as long 
as head. 
Thorax black ; pronotum and sides with rather long pale yellowish hairs, dor- 
sum -with pale golden scales, bristles at base of wings and on postalar caUi black ; 
underside of thorax black with black hairs ; scutellum black, with pale golden 
scales and black bristles, some of the latter being very long. 
Abdomen black; 1st segment with pale yellow hairs, 2nd with a narrow basal 
band of similarlj" coloured scales, 4th and 7th segments ■with broad basal bands 
of pure white scales ; venter black, sparsely clothed with greyish hairs and some 
yellow scales. 
Legs entirely black, with some pale scales on femora and tibiae. 
Wings brownish grey, with an oblique blackish baso-costal band reaching the 
tip of the 1st longitudinal vein, leaving the outer and posterior margins, including 
most of the anal and axillary cells, clear ; on the clearer portion are the following 
blackish spots or suffusions, viz., a spot near apex of upper branch of 3rd longi- 
tudinal vein, one at the fork of this vein, and one on the cross vein which joins the 
3rd and 4th longitudinal veins, one at the apex of discal cell, extending into 2nd 
posterior cell, one smaller spot at lower margin of discal cell where it is joined by 
5th longitudinal vein. The 1st posterior cell is closed a short distance before the 
marghi. 
Length 7-10 mm. 
Described from four good specimens from Matheran. There is a similar speci- 
men in the British Museum from Mahapur. 
This species is quite distinct from insulaia Walk, to which it bears a superficial 
lesejnblance ‘ (see remarks on that species below). It differs as follows ; the wings 
are somewhat shorter, and the 1st posterior cell is closed, whereas it is open in 
insulata. The latter species has apical bands of yellowish scales on the 3rd and 
following segments, that on 4th being the most conspicuous, whereas siva has 
broad basal bands of snow-white scales on 4th and 7th segments. The oblique 
basocostal band is narrower in siva, and the spots are smaller and differently 
placed. 
Exoprosopa albida. Walker. 
Five specimens from Deesa agree with the type and description of this species. 
The shape of the 1st posterior cell is evidently variable ; in the tj*pe it is closed 
and stalked ; one of my specimens agrees with the type, but in the others it is 
closed just on or near the margin. It varies considerably in size, my largest 
specimen measuring 16 mm., and the smallest 11 mm. This species is very doubt- 
fuOy distinct from E. bagdadensis Wled, which Becker records from Persian Bal- 
uchistan. The latter has the first two antennal joints testaceous, whereas 
in aliida the basal joint only is of this colour.
