275 MR. H. J. ELWES ON BUTTERFLIES FROM [Apr. 21, 



Neptis EXJRYNOME. 



Limenitis eurynome, Westw., Don. Ins. China, p. 66, t. xxxv. fig. 4. 



Neptis varmona, Moore, P. Z. S. 18/2, p. 561 ; Butt. Ind.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, eurymeiip, and 

 mamnja, and which are described and compared as far as possitde by 

 de Niceville, who appears to take much the same view as 1 do. 



If the South- Indian form described as varmona be compared alone 

 with tlie Chinese form called by We^twood eurynome, it might per- 

 haps 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 con- 

 sidered 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. 168, t. iv. a. 7 ; Butt. Ind. 

 ii. p. 104. 



This species seems fairly distinct though nearly allied 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 Bernardmyo and the Karen Hills, where it seems to 

 be fairly common. Neptis clinia of Moore, vaguely recorded from 

 Bengal and Siam, may, I think, be dropped from the Indian list as 

 a form which cannot be identified. 



Penthema darltsa. 



P. darlisa, Moore, P. Z. S. 1878, p. 829 ; Bntt. Ind. ii. p. 145. 

 Two or three in bad condition 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. 



.\lso found in the Naga Hills.
