type specimen ; the thirteen joints of the flagellum resemble those 

 of Psychoda hengalensis. The legs have the tarsi (except the 

 metatarsus, which is black nearly to the tip) entirely covered with 

 cream-coloured microscopic, scaly pubescence. The wings resem- 

 ble margininotata, and there appears to be a tendency to dark 

 spots of a similar nature, placed irregularly on the disc of the 

 wing, but especially on the bifurcations of the veins. 



The genital appendages as in margininotata, but rather longer. 



Described from three 9 ? in the Indian Museum, from 

 Calcutta, dated 28-vii-o8 (type), 2-viii-o8, and 17 — iS-viii-oy. 



N.B. — I place lacteitarsis and gilvipes as varieties of my 

 marginipunctata , as the markings of the wing seem to keep them 

 all within the range of one species and the variation in colour is 

 not more than is known to occur in other species. The technical 

 differences, therefore, rest with those of the tarsi, which may be 

 regarded as black with white tips in the typical form ; wholly 

 white in lacteitarsis ; and white with black metatarsi in gilvipes. 

 It is possible that my two varieties represent one species, distinct 

 from marginipunctata , in which case the name lacteitarsis had 

 better stand.

 9 . Darjiling. 



Body covered with dense, greyish white bristly hair; very 

 dense between the eyes and on lower part of face ; arranged on 

 the abdomen in transverse rows at the base of each segment. 

 They are long and semi-erect, thus covering most of the abdominal 

 surface. Antennae with both joints of the scape covered 

 with dense white scales, both joints appearing dark at their bases; 

 flagellum of fourteen subcorneal joints, the apical one produced to 

 a blunt conical point, each joint bearing a verticel of hairs, the 

 whole flagellum having a grey appearance. Palpi apparently 

 black, with white bristly hair. Genital appendage inconspicuous. 



Legs : Femora with long bristly grey hair ; 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 second longitudinal vein 

 and the fork of the fourth vein both occur a little before the middle 

 of the wing. The upper branch of the second 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 third vein originates in a 

 right angle from the fourth, just beyond where the second vein 

 divides into its upper and lower branches. 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
