of the female are very narrowly pectinated compared with those of 

 the male, but there is no other difference. 



This species was taken at 6000-/000 feet in the Naga Hills, by 

 Mr. Doherty, and seems to be the local representative of the genus, 

 of which only two others are known — S. venosa, Walker, a 

 shorter-winged species from the Khasia Hills, with the veins much 

 blacker and black fringes; and H. subhyalina, which is only known 

 by a male from the Lachung valley, Sikkim, SOOO-10,000 ft., which 

 is one of the insects I took myself in 1870, and gave to the late 

 Mr. Atkinson. I have compared my specimens with this, which is 

 now in Dr. Staudinger's collection.

 The type of this species came from the North-west Himalaya, 

 where it is not uncommon at moderate elevations, and extends with 

 some variation throughout the Himalayas to the Khasia and Naga 

 Hills, and, as I learn from M. Oberthiir, into the Chinese provinces 

 of Yunnan, Kouytcheou, and Szechuen. The Sikkim form might 

 almost be separated as a local variety, as in the male the red or 

 reddish-yellow stripes which run parallel to the inner margin do 

 not, in Khasia specimens, usually extend more than halfway to 

 the anal angle, whereas in Sikkim specimens they come almost to 

 the margin. The colour of the markings on the hind wing also is 

 less tinged with crimson than in Sikkim specimens. So far as I 

 have seen, North-western and Nepalese specimens are nearer to the 

 Khasia than to the Sikkim ones. I found this species common on 

 open grassy downs at 5000 feet near Shillong, in September, flying 

 heavily by day, but have not taken it myself in Sikkim. 



There is a dwarf form of this species found in Sikkim, the Naga 

 Hills, and the North-west Himalayas, which, though not differing 

 appreciably in markings, is constantly smaller in size '.
