165. Psychoda nigripennis, Bnm. (PI. lY, fig. 16.) 



Fsijchoda nigripennis, Brunetti, Ilec. Ind. Mus. ii, p. 376 (1908). 



<S $ . Body yellow, wholly covered with greyish brown hairs, 

 which in certain lights appear whitish. 



Head : eyes jet-black, facets very large. Antennae : basal joints 

 short and not broader than the flagellum, yellow, \\ith some black 

 bristles ; second joint spherical ; Hagellum of fourteen joints, of 

 which the first ten are flask-sliaped (as in P. hencjalensis) ; the 

 eleventh has no " neck," and is roughly ovate ; the twelfth, 

 thirteenth and fourteenth are very minute, the two former cup- 

 shaped, the terminal joint spherical. The verticels of greyish- 

 white hairs on each joint are very thick, lying closely, directed 

 forwards and clustering together, thus giving the antenna the 

 usual solid appearance, with parallel sides, of a grey colour, 

 marked with small black round spots. Palpi of four hairy elon- 

 gated cylindrical joints, of equal length, except that the fourth 

 is slightly longer and pointed at tlie tip. Ahdonun : genitaha of 

 the male very similar to those of P. heugcdensis, but the inlei'ior 

 appendages decidedly shorter. In the female tliey consist of a 

 very concave (on the upper side) leaf-shaped appendage, bending 

 backwards, but the appendage probably consists of two symme- 

 trical blade-like halves as in the other species. Lef/s pale blackish 

 brown ; the femora with some white hairs below, the tibiae rather 

 closely covered with snow-\\hite hairs, the tarsi blacker, with 

 white hairs which, towards the tip, are replaced by small elougated 

 white scales. Wings having the appearance of being pale blackish, 

 but really pale grey, wholly unmarked ; the veins distinct, each 

 with the usual double row of hairs, which appear black \\hen 

 viewed from above, but which appear white when viewed horizon- 

 tally from the tip of the wing. Eringe longest on posterior 

 border, grey, appearing dark in some lights and nearly white in 

 others. Wings with a purphsh iridescence.
