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 deeply blackish, with a slightly paler spot in a 

 line with the posterior 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 nearly clear oval spot touching 

 the costa, at the tip of the 2nd longitudinal and extending down- 

 wards into the 1st posterior cell ; a second, much fainter and more 

 irregular clear spot occurs just beyond the posterior 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, 7000 ft., 5-12. 

 viii. 09 (Jenkins and Paiva, common) ; Kurseong, 10-26. ix. 09 

 (Lynch) ; Gangtok, Sikkim State, 9. ix. 09 ; also two pairs taken 

 in cop., Darjiling, 5. viii. 09, and Gangtok, 6150 ft., 8. ix. 09. An 

 apparently immature specimen from Phagu, Simla hills, 12. v. 09 

 (Annandale).

clear parts of the wing more extended, but they apparently belong 

 to the same species. 



Of the three species ( R. fenestralis, distinctus, and divisus) taken 

 by Mr. Paiva at Darjiling in August 1909, 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 say now whether all 

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

 collecting identification was impracticable.
