214 Records of the Indian Miiseitm. [Vol. Ill, 



Wings practically clear; venation as in m}'- segmentatus, 

 except that the upper branch of the 2nd longitudinal vein takes 

 towards its tip a slight downward curve, thence curving rather 

 sharply upwards to the costa, and enclosing a well-marked, large, 

 dark brown stigma. Halteres : stem black, club yellowish. 



Described from a perfect $ (except denudation of thorax 

 and scutellum) in my collection, from Maskeliya, Ceylon, taken in 

 August, and sent me by Mr. E. Green. 



N .B. — This species should be near Bezzi's sauteri, but differs by 

 the black antennae ; yellow hairs on abdomen ; and the ver}^ differ- 

 ent proportionate lengths of the body and the wings. 



Exoprosopa niveiventris, mihi, sp. nov. 

 2 . West Bengal. Long. 18 — 20 mm. 



Head. — Frons, at widest (level of antennse), one-third the 

 width of the head, narrowing at vertex to half this width ; dark 

 brown, covered with close, light brownish orange scales, which 

 become lighter coloured below the antennae. The whole frons is 

 also covered with short black hairs; the ocelli are small, black, 

 close together, placed on a small tubercle. Mouth border yellow, 

 proboscis dark brown. Antennae black, first and second joints 

 thickly beset above and at the sides w4th strong black bristles ; third 

 joint rather long, absolutely bare, with a very distinct style, w^hich 

 itself bears a microscopic but distinct apical joint. From the 

 base of the antennae obliquely to the edge of the eye, there is 

 on each side of the frons a narrow groove, quite destitute of scales 

 or pubescence. Back of head broad behind the eye, with minute 

 black pubescence, and covered towards the sides with yellowish 

 white, soft scales, which may perhaps extend over nearly all the 

 back of the head in some specimens. A fringe of short, bright 

 orange-yellow hairs encircles the back part of the head, meeting 

 the dense pubescence of the thorax. 



Thorax dull black, with some short black hairs towards 

 anterior border, and in front of the scutellum. 



The front part of the thorax (not extending to the dorsum 

 proper) is covered densely with narrow, elongated, bright yellow 

 scales, which also extend to the sides of the thorax, and form fan- 

 shaped bunches below each shoulder, and behind each wing. 

 These scales become almost thick pubescence at the sides of the 

 dorsum, being especially thick above each wing. The true dorsum 

 is very sparsely covered with very short yellowish scales, which 

 probably even in perfect specimens never wholly cover the surface. 

 The scales at the sides of the thorax are more yellow than orange. 

 The posterior calli are prominent, ferruginous, covered with irregu- 

 lar small black bristles, with some yellowish white long scal}^ 

 pubescence on the outer side, and there are four powerful long black 

 spines placed close together and directed horizontally backwards. 



Scutellum ferruginous brown, an irregular double row of black 

 spines on posterior margin, and short yellow scales round the
