S. 1872, p. 561; Butt, lnd.ii. p. 95 et seq. I am unable to separate the numerous forms of this very wide-ranging species, which have been described by Moore as disrupta, adara, meetana, and kamarupa, by Butler as swinhoei, eurymene, and mamaja, and which are described and compared as far as possible by de Niceville, who appears to take much the same view as I do. If the South-Indian form described as varmona be compared alone with the Chinese form called by Westwood eurynome, it might perhaps be separated ; but on bringing together a very large series of nearly 100 specimens from all parts of India, China, and Burmah, I can find no reason for doing so, and think that they may be considered as the tropical form of N. aceris, which occurs in Europe, Amur-land, and Japan, from which they are principally distinguished by the yellower colour of the underside. N. aceris is represented in the Himalayas by N. mahendra, which I should consider identical with it. L. eurynome seems common everywhere, and was taken by Doherty in the Naga and Karen Hills and at Perak. NEPTIS NANDINA. N. nandina, Moore, Cat. E. I. C. i. p. 1 68, t. iv. a. 7; Butt. Ind. ii. p. 104. This species seems fairly distinct though nearly aliied to N. aceris ; de Niceville says that it may be recognized by the sudden widening out at the costa of the discal band on underside of hind wing. This I find to be hardly the case in my series. I should say rather that the band becomes gradually broader in nine cases out often. I received specimens from Bemardmyo and the Karen Hills, where it seems to be fairly common. Neptis clinia of Moore, vaguely recorded from Bengal and Siam, may, 1 think, be dropped from the Indian list as a form which cannot be identified. PENTHEMA DARLISA. P. darlisa, Moore, P. Z. S. 1878, p. 829 ; Butt. Ind. ii. p. 145. Two or three in bad conditiou from the foot of the Karen Hills. LIMENITIS ZAYLA. L. zayla, Doubl. & Hew. Gen. D. Lep. t. xxxv. 4; Butt. Ind. ii. p. 159. Not a rare species in the Naga Hills, and does not differ from Sikkim specimens. LIMENITIS DUDU. L. dudu, Westw. Gen. D. Lep. ii. p. 276 (1850) ; Butt. Ind. ii. p. 159. Also found in the Naga Hills. |
