ON NEW AND LITTLE-KNOWN BUTTERFLIES. 249 



tiafced in the same way by the white areas being heavily frosted 

 with bluish scales, the extent of these bluish- white areas being as 

 variable as in the male ; and the apes of tbe foreioing also varies in its 

 greater or lesser acumination. 



All writers on Japanese butterflies have called the species of the 

 genus Curetis occurring there C. acuta, Moore, which was originally 

 described from Shanghai in North China, and of which the C. 

 trancata of Moore, and the C. angidata of Moore are, in my opinion, 

 synonymous. C. acuta occurs from the eastern coast of China (Shan- 

 ghai and Hongkong) to the Western Himalayas. The female has 

 the wings above with white central areas. The late Mr. H. Fryer's 

 figure of the female of the Japanese Curetis is very bad, as it shows 

 the upperside of both wings white instead of bluish-white as it is, 

 1 believe, invariably. He describes it as " blue." C. paracuta appears 

 to be a fairly common species in Japan, Fryer giving four localities 

 for it. Leech the mountains of Central Japan, and I have it from Tokio 

 and Nikko, besides other places not specified. 



12. Chrysophanus evansii, n. sp. Flate FF, Fig. 11 ^. 



Habitat : Drosh, Chitral, Western Himalayas. 



Expanse: (J, 1"3 inches. 



Description: Male. Closely allied to C. sarthus, Staudinger* 

 from the Pamirs, from which it appears to differ in being larger and 

 the forewing narrower and more elongated. Upperside, hindwing 

 has the anal orange patch much smaller, reduced to a small and 

 narrow streak on the submedian nervure. Underside, forewing has 

 the orange area larger, occupying nearly the entire surface, the black 

 spots fewer ia number, the spot behind and opposite the one in the 

 middle of the discoidal cell in C. sarthus absent, and the discal series 

 entirely absent ; the spots of the submarginal series are smaller. 

 tlindwing the same as in C. sarthus. 



Described from a single specimen kindly given to me by Mr. W. H. 



Evans, R.E., who captured it.
