KHYPHUS. 557 



there is generally a more or less distinct broad irregular blackish 

 band occupying about the middle third of the hind femora, and 

 the hind tibiae are more or less blackish for some distance at both 

 base and tips ; legs minutely pubescent. Wings very pale grey, 

 with brownish markings ; the cross-veins rather deeply but nar- 

 rowly brown, whilst moderately dark brownish markings occur as 

 follows : a square mark in the middle of the upper basal cell ; a 

 well-defined brown streak from the middle of the costa, narrowing 

 grail ually, passing between the above-mentioned square mark and 

 the anterior cross-vein, crossing the base of the discal cell and 

 continuing narrowly along the 5th longitudinal vein ; a broader, 

 also well-defined, stripe from the costa (narrowing hindwarcls) 

 passing clear of the posterior cross-vein, terminating at the 

 upper fork of the lower branch of the 4th longitudinal. The tip 

 of the wing down to the 3rd longitudinal vein is brown, leaving 

 in front of it a distinct square-shaped, quite clear spot, touching 

 the costa and contiguous to the previously described stripe. It 

 may be described differently by saying that the whole of the costa 

 is brownish, deepening towards the tip, with a quite clear square 

 spot placed just touching the tip of the 2nd longitudinal vein, 

 extending from the costa to the 3rd longitudinal. The distal part 

 of the wing, from below the 3rd longitudinal down to a little 

 beyond the lowest branch of the 4th, is light brownish grey, 

 leaving a clearer streak across the 1st, 2nd, and 3rd posterior cells,, 

 just before their centres and almost below, but a little previous 

 to, the clear square costal spot. Nearly below this latter spot, 

 but a little beyond it, yet just touching it in the 1st posterior 

 cell, is a nearly upright, oblong, quite clear spot, on the outer 

 side of which the brown colour is distinctly deeper for a very 

 small space. The 6th longitudinal vein is very narrowly and not 

 deeply suffused. Halteres yellowish. 



Length 3-4 millim. 



Described from a number of both sexes from Darjiling, 7000 ft.,, 

 5-8. viii. 09 (Paiva), and a female from Kurseong, 2000 ft. below 

 Darjiling, 4. ix. 09 (Annandale). I have also seen a specimen from 

 Kowpati, Mangaldai, Assam, 12. xii. 10 (Kemp}.

c? $ . This species considerably resembles R. distinctus, but 

 differs in some minor characters, and very essentially in the wing 

 markings. The row of stiff hairs behind the eyes and across the 

 vertex is stronger ; the basal abdominal segments in the male are 

 more yellowish on their posterior borders, and the middle line on 

 the thoracic dorsum is very distinctly divided ; the blackish band 

 on the hind femora is confined to the male, whereas in K. distinctus 

 it is sometimes present, though indistinctly, in the female. The 

 wing markings are entirely different : on a pale grey ground-
