3o6 Records of the Indian Museum. [Vol. IV, 



The metatarsus is, with the exception of its immediate base, 

 covered rather thickly with whitish scales (in the type and in one 

 other specimen), or at least for more than the apical half (as in the 

 third specimen). 



In margininotata the last three tarsal joints often have a 

 grejdsh or blackish grey appearance, but in the present species 

 they are all uniformly intensely black. 



The second character is that the fringe of the wings possesses 

 no admixture of whitish hairs either singly or in short sections, 

 with the exception of a broad section at the tip, comprised 

 between the lower branch of the 2nd longitudinal vein and the 

 upper branch of the 4th vein. 



The 2nd longitudinal vein forks a short distance before the 

 base of the 3rd vein, at which spot is placed the anterior cross- 

 vein ; the fork of the anterior branch of the 2nd vein is distinctly 

 proximad of the fork of the 4th vein. 



In view of the close affinity of lacteitarsis and gilvipes to 

 margininotata, although they appear to be perfectly good species^ 

 there seems no reason to refrain from establishing the present 

 form as a distinct species. 



Described from three 9 $ from Simla district, two from 

 Simla, 9-V-09 (type) and 12-V-09, the third from Phagu (g,ooo ft.), 

 ii-v-09, all taken by Dr. Annandale.

Of the general appearance of that form of margininotata, 

 which was described as bella. 



Body with blackish and gre^- hairs, the former predominating 

 chiefl}' on the dorsum of the thorax and at the base of the wings. 



The imngs have a dark brown appearance. The 2nd longitu- 

 dinal vein forks some little distance beyond the base of the 3rd 

 vein, although still quite near the base of the wing, as the latter 

 vein begins sooner than in most species, its exact origin near the 

 root of the wings being obscured by the pubescence. The fork of 

 the upper branch of the 2nd vein and the fork of the 4th vein are 

 approximately opposite one another. The veins are closely covered 

 with a double row of black or dark brown hairs, with a distinct 

 black hair-spot at the tip of each vein ; a few small pale hairs in 

 front of some of these black hair-spots. Some erect short, snow- 

 white hairs towards the bases of the veins, and others on the three 

 branches of the 2nd vein, placed some little distance before their 

 tips ; also to a less extent in .short sections on the veins in other 

 parts of the wing. 



A number of bright yellow hairs, distributed (i) along the 

 veins, apparently thickest along the costa, especially at its base, 

 intermixing with the normal, thick black or dark brown hairs 

 forming the fringe, (2) at the bases of the veins, but disposed in
