264 Records of the Indian Museum. [Voi,, IV, 



On a pale grey ground colour, the cross-veins are deeply but 

 narrowly infuscated as is also the 5th longitudinal vein; the 

 proximal two-thirds of the marginal cell is rather deeph' blackish, 

 with a slightly paler spot in a line with the outer cross-vein ; the 

 distal part of the wing is light blackish grey , much deeper at tip 

 just above the 3rd longitudinal vein and a little below it, leaving 

 a nearl}^ clear oval spot touching the cost a, at the tip of the 2nd 

 longitudinal and extending downwards into the ist posterior cell, 

 a second, much fainter and more irregular clear spot occurs just 

 beyond the outer cross-vein. The praefurca appears slightly 

 obliterated about its middle. Halteres yellow. 



Described from a good series of both sexes in the Indian 

 Museum from the following localities : — 



Darjiling {7,000 ft.), 5 — i2-viii-09 [Je^ikins and Paiva, coni- 

 mon]; Kurseong, 10 — 26-ix-09 [Lynch]; Gangtok, Sikhim State, 

 g-ix-og; also two pairs taken in cop., Darjiling, 5-viii-09, and 

 Gangtok, S-ix-og. An apparently immature specimen from Phagu, 

 Simla hills, 12-V-09 [Annandale]. 



A cf and two $ $ taken at Darjiling in company with the 

 others have the thoracic markings almost obliterated^ and the clear 

 parts of the wing more extended ; but the}^ apparently belong to 

 the same species. 



N .B. — Of the three species {fenestralis , distinctus and divisus) 

 taken b}' Mr. Paiva at Darjiling in August, igog, he says that 

 some were taken on windows and others along the roads of the 

 town, where they were hovering in small swarms under the shade 

 of the trees, but it would be impossible to sa}^ now whether all 

 the species occurred in both habitats or not, as at the time of 

 collecting, identification was impracticable. 



DIXIDAE. 



This family, like the Rhyphidae, contains but a single genus — , 

 and this one, Dixa, has not previously been recorded from the 

 East. Five species are here offered as new, as I am unable to 

 identify an^^ of them with such descriptions of Palaearctic species 

 as are accessible to me. 



DIXA, Meig. 



Table of species. 



A Wing with more markings than a 

 narrow transverse streak across the 

 middle. 



B Wing tip not infuscated. Thoracic 

 stripes dark brown, abdomen brown. 



C Wing nearly clear; only a few infus- 

 cated spots, mostly in basal and 

 anal cells: no deeper black spots . . montana, sp. nov, 

 CC Wing with several blackish streaks ;
