In L. bhairava there is a large patch of black scales on the inner margin of the fore wing on the upperside, but it extends into the submedian interspace. L. gulnihal is nearest to L. bhairava, its markings being very similar ; but it is smaller, and the bowed inner margin of the fore wing will at once distinguish the males of the two species. Two male specimens have been obtained in Bhutan by the native collectors of Messrs. Otto Moller and A. V. Knyvett, in whose collections the specimens above described are deposited. LETHE BRISANDA. (Plate XXXIX. fig. 8, 3 •) L. brisanda, de Nice'ville, Journ. A. S. B. vol. Iv. pt. ii. p. 249. n. 1, pl. xi. fig. 13, female (1886). Hab. Bhutan. Expanse. 3 2"4 inches. M A L E . Differs from fresh native Sikkim specimens of L. dinarbas on the U N D E R S I D E of the fore wing in the lilac band across the middle of the discoidal cell being much narrower, with uneven instead of straight edges ; the discal oblique band lilac throughout, straight, and of equal width throughout (in L. dinarbas the upper portion of the band only is lilac, this portion too in that species being wider); in having an additional ocellus in the subcostal interspace (in a long series of L. dinarbas before me there are always three ocelli only). On the hind wing the discal bands are deep brown instead of ferruginous, and the lilac washings throughout much more brilliant. Should the above-given characters prove constant in a large series of specimens, the males of L. brisanda and L. dinarbas will be easily distinguishable, the latter species being apparently very uniformly marked. The females are abundantly distinct. A single male has been obtained near Buxa, Bhutan, by Mr. A. V. Knyvett's native collectors. MELANITIS BETHAMI, n. sp. Hab. Pachmarhi, Central Provinces, 3500 feet. Rainy-season form. Expanse. 3 2'8, $ 3 inches. M A L E . U P P E R S I D E : both wings sooty black. Fore wing with the outer margin paler, the apex very slightly truncate, there being a small notch only below the lower discoidal nervule, a well-defined subcostal nearly round ochreous patch beyond the cell divided into three portions by the discoidal nervules. Hind wing unmarked. U N D E R S I D E : both wings paler than above, densely and evenly striated with darker, the outer margin ferruginous. Fore wing with four small obscure discal ocelli, of which the two in the second median and upper discoidal interspaces are the largest. Hind wing with a series of six submarginal ocelli, the second from the apex minute, the anal one geminated, the other four subequal and much |
