a patch of black hairs at the tip of all the veins from the first to 

 the lower fork of the fourth (inclusive), with a trace of a patch at 

 the tip of the fifth ; and a patch of white hairs appears between all 

 these black patches ; so that the border of the wing appears 

 spotted alternately black and white, and is fringed along its entire 

 length with close, long, light brown hair. The hair of the wing 

 appears lighter or darker in different specimens, and according 

 to the direction in which the light falls on it, a brilliant iridescence 

 being at times visible. 



Described from two specimens in the Indian Museum from 

 Sylhet (Major Hall), i-i-05 and 30-1-05, also from a third specimen 

 mounted on a slide, in the same collection. 



Psychoda albonotata, mihi, sp. nov. 

 ? . Calcutta. Long, i mm. 



Body: Ground colour black. Thorax and abdomen with 

 whitish grey hairs which in certain lights appear silvery. 



Head: Eyes black, facets large ; interocular space light brown, 

 filled with strong, rather long black bristles. Antennae sixteen- 

 jointed, light brown; two basal joints cup-shaped, rather short, 

 with circlets of stiff black bristles ; the flageilum of fourteen 

 cup-shaped joints placed rather close together, and bearing the 

 usual long hairs which are both thick and long. Palpi dark brown, 

 hairy. 



The genital apparatus appears to be a moderate-sized, bare, 

 pointed, pale yellowish brown appendage, similar to that of this 

 sex in other species. 



Legs with livid yellow femora and tibiae, the latter black 

 towards the tips ; tarsi brownish black, covered with close, brownish 

 scales. The extreme tip of the tibiae, of the metatarsus, and of the 

 last tarsal joint, with a few brilliant, snow-white hairs. 



Wings with the upper prong of the second longitudinal vein 

 originating much before the fourth part of the total length of the 

 wing ; the fourth longitudinal vein bifurcates at about one-fourth 

 of the wing. Ground colour dark grey, the veins with the usual 

 double row of hairs, which are black, giving, with the long fringe 

 of black hairs around the whole wing-border, a wholly black 

 appearance to the wing. A silvery white spot formed by a few 

 minute, very elongate, hair-like white scales, at the tip of all the 

 veins, from the first to the sixth inclusive, nine spots altogether. 



Described from a female in excellent condition in the Indian 

 Museum collection, taken in Calcutta, 5 — 6-i-o8. 



N.B. — The general appearance of this species is that of a 

 black Psychoda with nine snow-white spots on the wing-border, and 

 with white spots on the legs. In certain lights nearly all parts of 

 the body in turn appear more or less silvery white, including the 

 black wing-fringe, the femora and tibiae, and nearly the whole
