242 PSYCHODID^. 



The,v are long aud semi-erect, thus covering most of the abdominal 

 surface. 



Head : antennae with both joints of the scape covered with 

 dense white scales, both appearing dark at their bases ; flagellum 

 of fourteen subconical joints, the apical one produced to a blunt 

 conical point, each joint bearing a vertical of hairs, the whole 

 flagellum having a grey appearance. Palpi black, with white 

 bristly haii-s ; the 4tb joint the longest and thinnest. Legs : 

 femora with long bristly grey hairs ; hind pair thickly covered 

 with whitish scales. Tibiae blackish brown with long, irregularly 

 placed bristles ; a ring of close, short, black bristles towards the 

 tip, and a circlet of closely packed, elongated, white scales at the 

 tip. Metatarsus and tarsal joints black, with a circlet of short 

 white scales at the tip of most of them. Wings : fork of the 

 upper branch of 2nd longitudinal vein and the fork of the 

 4th vein both occurring a little before the middle of the wing. 

 The upper branch of the 2nd vein, immediately after its origin, 

 takes a rather sudden curve upwards, descending slightly to 

 where it forks, and the lower branch ends only slightly above the 

 extreme tip of the wing ; the 3rd vein originates in a right 

 angle from the 2tid vein,* just beyond where the latter forks, its 

 basal portion very narrow but quite distinct in wings denuded of 

 vestiture, and there is a distinct appendix at the angle. The veins 

 bear the usual double row of greyish, semi-erect hairs, and patches 

 of black, erect, bristly hairs are distributed as follows : — at the 

 fork of the upper branch of the 2nd vein, and at (or just beyond) 

 the similar fork of the 4t[i vein ; also about the middle of the 6th 

 aud along the 7th, except in its centre. The fringe round the 

 border of the wing is generally greyish white, with an arc of 

 black bristly hairs near the middle of the costa, and just beyond 

 the middle ; on the posterior border between" the lower fork of 

 4th vein and the 5th ; also from the end of the 6th nearly to 

 the base of the wing. 



Described from six females taken by me on windows at Darjiling 

 during the last few days of September, and on October 1st, 1908. 

 It was not uncommon.

The patches of black hairs on the wing are by no means of 

 regular size or shape, but the markings of the six examples 

 examined agree fairly well with the distribution of black hairs as 

 herein described. Small irregular patches occur in nearly all the 

 specimens. Sometimes the general appearance of the wing is 

 wholly blackish or black, with a slightly curved band of lighter 

 hairs across it near the tip ; a patch of white hairs in the middle 

 of the costa, and beyond the middle on the hind border, and also 

 at the tip of the wing. 



* Not from the 4th vein, as erroueously stated in my original description.
