This species was taken at 6000-7000 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-LL. venosa, Walker, a shorter-winged species from tbe 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, 8000-10,000 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. Genus CAMPYLOTES, Westwood. CAMPYLOTES HISTRIONICUS, Westw., Royle, 111. Him. p.liii, t. 10. fig. 1 (1837). Chalcosia histrionica, Koll. Hugel's Kashm. p. 463 (1848). 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'.
