224 PSYCHODID^:. 



replaced by white or greyish ones, and irregularly placed along 

 most of the veins, as well as at the tips, are very small spots 

 composed of a few white hairs, which (to the extent of twenty or 

 more) give the whole wing a spotted appearance that immediately 

 distinguishes it from all other species. 



Length I millim. 



Described from a single specimen, apparently a male, in good 

 condition, from Peradeniya, Ceylon, 17. vi. 10 (E. E. Green).

$ . 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 flagelluin of fourteen cup- 

 shaped joints, placed rather closely together, and bearing the usual 

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

 Abdomen : the genital apparatus appears to be a moderate-sized, 

 bare, pointed, pale yellowish brown appendage, similar to that ot 

 this sex in other species. Legs with livid yellow femora and 

 tibise, 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 2nd 

 longitudinal vein originating much before the fourth part of the 

 total length of the wing ; the 4th 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, the surface of which is 

 covered with hairs placed longitudinally. Some distinct shortly 

 elongate dark brown scales over the base of 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. 



Length 1 millim. 



Described from a female, in excellent condition, in the Indian 

 Museum collection, taken in Calcutta, 5-6. i. 08. 



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 of the 

 pubescence on the body ; the wiugs also, in certain lights, present 

 a beautiful iridescence.
