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 before the fork of 

 the 4th vein. 



Length 1| millim. 



Described from three females from Simla district, two from 

 Simla, 9. v. 09 {type) and 12. v. 09, the third from Phagu, 9000 ft., 

 11. V. 09, all taken by Dr. Annandale. 



Type and the other specimens in the Indian Museum. 



In view of the close affinity of P. lacteitarsis and P. gilvipes ^ to 

 P. margininotata, although they appear to be perfectly good species, 

 there seems no reason to refrain from establishing the present 

 form as a distinct species.

$. Of the general appearance ' of P. margininotata var. hella. 

 Body with blackish and grey hairs, the former predominating 

 chiefly on the dorsum of the thorax and at the base of the wings. 



Legs dark yellowish grey, thickly clothed with stiff bristly 

 hairs ; the tibia?, the metatarsi and 2nd joint of tarsi with a narrow 

 circlet of whitish scales at the tips of each. Wings having a 

 dark brown appearance. The 2nd longitudinal 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 wdngs 

 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 shortsnow-white 

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

 branches of the 2nd vein, placed at 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 : — 

 (1) 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 small sections separate from the snow-white ones in 

 that region of the wing ; and (3) on the three branches of the 

 2nd longitudinal vein before the white hairs. To an apparently 

 less extent they also occur on the veins in other parts of the 

 wing. The wing-fringe on the posterior margin is really dark 

 brown, although in some lights it appears light brown or even 

 greyish here and there. The tip of the wing bears a few whitish
