PSTCHODA. 225 



Hall), 8. i. 05, is apparently the same species. The hairs on the 

 wing are golden brown, and those on the body more brownish 

 than in the Calcutta specimen, whilst the \vhite scales cover the 

 whole of the metatarsus. The antennae are missing, and there 

 are a few white, elongated, hair-like scales in the centre of the 

 wing towards the base. The wing-fringe is golden brown on 

 the distal half and black on the basal part of the costa and 

 on most of the posterior margin. 



In a note appended to the original description is mentioned a 

 specimen from Sylhet with a few remaining white scales on the 

 surface of the abdomen near the base, but closer investigation 

 reveals that they must have become accidentally attached, forming 

 no part at all of the insect's vestiture.

$ . Body pale brownish yellow, entirely clothed with long, pale 

 brownish yellow, bristly hairs, with some concolorous elongated 

 scales, and with a few black bristles here and there. The bristles 

 are long, and become scale-like on the dorsum of the thorax and 

 towards the tip of the abdomen, where, in the latter case, the 

 black bristles are also more numerous. 



Head: eyes black, with dense, soft, pale yellowish grey hairs 

 between them. Anteunse sixteen-jointed ; first joint of scape 

 cylindrical, second spherical ; flagellum of fourteen elongated, 

 pear-shaped joints, each surrounded by numerous long hairs in 

 the form of a rather irregular verticel. Legs with numerous 

 bristles, which are very long on the tibias, which, in addition, have 

 short scales of the same colour lying rather close, and a circlet of 

 rather long, scale-like bristles at the tips. The metatarsus, which 

 is nearly as long as the four remaining subequal joints together, 

 has a few irregular bristles, and the tarsi are covered by close- 

 lying, pale yellowish white scales, giving a whitish appearance in 

 certain lights. Wings : the upper prong of the 2nd longitudinal 

 vein forks near the base, before one-third of the wing, and the 

 4th longitudinal vein forks at exactly one-third. All the veins 

 seem to bear the usual double row of hairs, and the intervening 

 spaces are also covered with brown hairs rather thickly ; there is 

 a patch of black hairs at the tip of all the veins from the 1st to 

 the lower fork of the 4th (inclusive), with a trace of a patch 

 at the tip of the 5th ; 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 hairs. The hairs of the wing 

 appear lighter or darker in different specimens, according to the 

 direction in which the light falls on them, a brilliant iridescence 

 being at times visible.
