siderable, and it would bo necessary to make many local inquiries in 

 order that the names of the parganas might be correctly given. But 



they would be valuable historical documents. Perhaps Mr. Beames, 

 who lias already done something- for the geography of the Akbanniina, 

 might undertake the tusk.

6. Note on three North Indian Butterflies — Euthalia nara, E. saha- 

 deva, and E. anyte. By Lionel de Nice'ville, F. E. S., C. M. Z. S. 



~Eufha.Ha nara, Moore, E. sahadeva, Moore, and E. anyte, Hewitson, 

 have always proved to be puzzling species both to collectors and cabinet 

 naturalists. E. nara was described from a, female, E. sahadeva from a 

 male, and E. anyte also from a male. All three species occur in Sikkiin. 

 That region has been so thoroughly well worked ontomologieally of recent 

 years that it is inconceivable that the opposite sexes of three such large 

 butterflies should be still uncaptured, and, on looking over the material 

 at my disposal in consequence of the receipt of a letter from Mr. H. J. 

 Elwes, suggesting that E. sahadeva is the male and E. nara* the female of 

 one species, I find that I can discriminate the opposite sexes of all the 

 thi'ee species with ease. The short diagnoses given below will, I think, 

 enable any one having specimens of these species to distinguish between 

 them without difficulty. In " The Butterflies of India" I described as 

 the supposed male of E. nara, a specimen which now proves to be the 

 true female of E.nara; what I, at the time of writing, took to be 

 E. nara female turns out to be the true female of E. sahadeva. It is 

 strange that Mr. Elwes should have omitted E. anyte from his " Catalogue 

 of the Lepidoptera of Sikkim," as it has been recorded Erom thence mote 

 than once. In the Proc. Zool. Soc. Lond., 1891, p. 279, Mr. Elwes 

 describes the supposed female of E. anyte * I am unable to follow his 

 description, nor can 1 agree with his conclusions, as I contend that 

 E. nara and E, anyte are female and male respectively of one and the same 

 species, which stands under the former name. Euthalia iva, Moore, 

 described as a male from Darjeeling, is probably a female, and has still to 

 be re-discovered. 



* Since this article was pnl into type I have heard again Prom Mr. Elwes, and 



he tells me that the specimens which lie tu..l, in i" 1 the Fi males of /■•'. nara are really 

 the opposite sex of E. sahadeva.
