CUEETIS.

tlie fore wing l)eitjg pointed and acuminated at tlic apex ; the red area is paler and broader, 

 extending to the jjosterior margin towards the base ; the dentate mark at the end of the cell 

 is also prominent. On the hind wing the exterior margin is much produced to an angle in 

 the middle, and the anal end more produced ; the red area is also paler, and extends from the 

 costal edge broadlj- over the disc, leaving only an exterior marginal blackish band and a 

 sufl'used medial basal area. 



" Female. With similar outline of wings, and broad white discal areas. Expanse 1| inch. 



" N.W. Himalayas." {Moore, I. c.) 



I have only one example of each sex ; these were taken in the Ichang Gorge 

 in September. The male agrees very well with Moore's figure of angulata. 



Elwes (Trans. Ent. Soc. Lond. 1888, p. 372) seems to regard angulata, 

 denfata, and discalis, Moore, as forms of C. buUs, and in this I am inclined 

 to think that he is probably correct. 



In the Moller collection there are thirty specimens of Curetis which have 

 been arranged in series according to the angulation of the wings and the 

 amount of red colour on upper surface of the males and of bluish white in 

 the females. Mr. de Niceville considers all these to be referable to one 

 variable species, i. e. C. bulis. 



Curetis acuta.

Nihon. p. 1], pi. iv. figs. 1, 2 (1887). 

 Curetis truncata, Moore^ 1. c. p. 51 (1877). 



" J^earest to C. hidis, Bd. ; differs in both sexes in the acute prolongation of the apical angle, and 

 obliquit}' of the outer margin, of the fore wing ; darker colour ; the golden (in the male) and 

 white (in the female) portion of both wings less prominent, being confined to a smaller space 

 on the middle of the wing. Expanse 2 inches. 



" Shanghai." {Moore, 1. c.) 



Tar. truncata, lloore. " Female. Brown ; fore wing indistinctly paler towards the base ; hind 

 wing whitish narrowly on anterior margin and slightly at the apex. Underside less iirorai- 

 nently marked than in C. acuta. Expanse 1| inch. 



" Shanghai." {Moore, I c.) 



In this species the angulation of the wing is subject to considerable varia- 

 tion, and I cannot find any specific difference between C. acuta and the insect 

 which Mr. Moore has described as truncata. 



Occurs in some numbers at Chia-ting-fu and Omei-shan in Western China, 

 also at Chang-yang and Kiukiang, and is common in the mountains of 

 Central Japan.
