286 Record:^ of the Indian Museum. [Vol. IV, 



Thorax as in previous species, except that the scutellum is 

 shghtly reddisli brown at the tip, and that (being denuded) no 

 golden yellow hair is visible on its dorsum, though such is prob- 

 ably present in perfect specimens. 



Abdomen wholly black, dull. 



Legs. — Fore coxae yellowish, posterior coxae black: all 

 trochanters brownish yellow. Femora black, but fore pair a little 

 yellowish at the base. Fore tibiae whitish yellow, except a little 

 blackish at the tip, posterior tibiae 5"ellowish on basal half, 

 blackish on apical half. Tarsi exactly as in the previous species. 



Wings clear; venation normal. Halteres bright yellow. 



Described from a single type 9 in the Indian Museum, taken 

 by Dr. Annandale at Kurseong, i8-vi-io. 



Simulium indicum, Becher. 



This species was described originally (Journ. Asiat. vSoc. 

 Bengal, liii, igg, pi. xiv) in 1884 from female specimens in the 

 Indian Museum from Assam. 



It appears to be fairly common and widely distributed along 

 the Himala^^as and into Assam, the Museum possessing specimens 

 from Mussoorie (7,400 ft.), 19-X-09 [Badley Scott]; Simla (7,000 

 ft.), i4-iv-07 [Annandale] ; Darjiling (7,000 ft.), la-viii-og [Jenkins] ; 

 Kurseong, 10 — 26-ix-09 [Lynch]; Sylhet, i8-iv-05 [Hall]; Khasi 

 Hills, "Assam," 2-iii-05 [Hall]; and Jaunsa, Tons Valley [C. G. 

 Rogers]. 



Of the cf , which has apparently not previously been recorded, 

 there are two specimens from the island of Bombay, 25-xi-OQ, one 

 of which I propose as the new type of the species, the original 

 type $ not being traceable. 



Two other 9 $ in the same collection appear to represent a 

 variety with wholly black abdomen; they come from Darjiling, 

 io-viii-09 [Paiva], and Ukhral, Manipur (6,400 ft.) [Peitigrew]. 



The extent of the yellow on the abdomen is verj^ variable, in 

 the series of specimens examined. 



In general appearance the species resemble aureohirtuni, but 

 differs in the following points : — 



The frons is shining greyish white, the humeral calli are dis- 

 tinctly and rather broadly reddish brown, the colour varying in 

 extent ; the sides of the thorax are distinctly gre}^ dusted (in one 

 example there is a grey dusted band along the lateral margins of 

 the dorsum) ; the antennae are always more or less reddish brown 

 at the base. The two principal specific characters are, the yellow 

 colour of, generally at least, the first two abdominal segments, 

 and the fore metatarsi are distinctly incrassated as well as length- 

 ened. The fore coxae are yellowish, the posterior ones blackish; 

 the femora and tibiae are pale on the basal half, the remainder 

 being black; the fore and hind tibiae are shining whitish yellow. 

 Tarsi black, posterior metatarsi pale on basal half, more so on 

 hinder pair. The fore metatarsus and hind metatarsus are both
