356 Records of the Indian Museum. [Vol.. Ill, 



Abdomoi, c , reddish yellow, dorsum, especially of the third 

 and fourth segments, violet-black, fifth yellow. 5 , wholly violet- 

 black, tip greenish, shining. 



In the cf the third, fourth and fifth segments each bears a pair of 

 strong bristles towards the posterior border, but they are not visible 

 in the 9 (the 9 specimen is in equally good condition as the o» ). 



Legs (middle pair wanting in o» ) yello.v, posterior tibiae brown- 

 ish ; tips of tarsi black ; coxae in o* pale yellow ; posterior femora 

 in 9 brownish towards tips. Fore femora in cf enlarged with a 

 bump in the middle, below, bearing three short spines. A single 

 strong long spine precedes the bump, which is followed by the leaf- 

 shaped appendage bearing a short spine. A little black hair at the 

 base, on ihe inside of the fore femora, and a strong spine on the 

 outer side, in the middle. Fore tibiae ( ■■y ) contracted at base and 

 mid lie, with a few bristles on basal half. Posterior femora ap- 

 parently bare of bristles ; posterior tibiae with a few bristles on 

 apical half. 



Wings as in tinda ; inner cross-vein distinctly beyond middle 

 of discal cell ; two basal cells distinctly separated. 



Described from a pair in cop. and an additional a' taken at 

 Shasthancottah, 12 miles N.N.E. of Ouilon, South India, by Dr. 

 Annandale, 8-xi-o8; a cf from Rajmaha), Bengal, 5-vii-09 [Annan- 

 dale]; and a cf from the Garhwal District, Western Himalayas, 

 9-V-09. 



N.B. — This species is the only one seen by me in which so 

 much difference appears in the sexes, and but for Dr. Annandale's 

 assurance that they were personally taken in cop. by him, I 

 should have regarded them as distinct. The species is near 

 both flava {cf) and coprophila ( 9 ) but may be distinguished from 

 each by the basal cells being distinctly separate, instead of 

 united. I know of no species in which the abdominal strong bristles 

 are present in the cf only, yet there is no trace of any in the type 

 9 of this species, which specimen is in as equally good condition 

 as the cf . 



Sepsis dilata, mihi, sp. nov. 



? cf . Bengal. Long. 2| mm. barely. 



Head.— Vrons and back of head black; antennae, face, pro- 

 boscis and lower part of head, reddish. 



Thorax black, two dorso-central bristles, curved inwards at tip. 

 Thetwoscutellar bristles rather close togsther, long, somewhat erect 

 and waved. Sides of thorax, especially towards the front, slightly 

 dark brown. Sternopleurae not white dusted. 



Abdomen shining black, with soft hairs only. 



Legs. — Fore pair yellow, posterior legs reddish, hind femora 

 slightly brownish, hind tibiae black, also tips of tarsi, and hind meta- 

 tarsi, the latter with a few large spines below at base. Hind tibia 

 distinctly dilated on apical half. Middle femora with a bristle in 

 the middle in front and a row of short stiff hairs below near tip ; 

 middle tibiae with a bristle on inner and on hinder sides towards tip.
