also are decidedly smaller, as in L. argiolus, and have the submarginal luuules and spots below 

 much less strongly defined. Expanse of wings, S 30-34 millim. Jinchuen, "W. Corea." 

 (Butler, I. c.) 



All my specimens of L. argiolus from Eastern Asia differ from the Euro- 

 pean type in the greyer coloration of the under surface, Avhich is also without 

 any bluish suffusion, and the marginal black borders are more pronounced on 

 the upper surface. Some of the specimens agree very well Avith L. Jcasmira 

 Moore { = ccelesUna, Kollar), Proc. Zool. Soc. Lond. 1865, p. 503, pi. xxxi.

Piyer states that there are several broods of L. argiolus in Japan during the 

 year. I found the species common throughout Japan and Corea during the 

 warm season, and noticed that it was as variable in those parts of Eastern 

 Asia as it is in Europe. The same remark applies to specimens from China, 

 where the species is common in all the places visited by my collectors. 



In wing-expansion the specimens vary from 27-36 millim., and in the 

 width of the black marginal border of primaries there is considerable 

 diversity. 



The Indian L. Imguelii, Moore, does not appear to me to be specifically 

 distinct from L. argiolus, and I think that it, and also L. ccelestina, Kollar, 

 are really only forms of that species. 



A widely distributed and variable species. It occurs throughout Europe 

 and North Asia (except the Polar region), Eastern and Western Asia, Japan, 

 China, the north of Africa. 



Cyaniris oreas, sp. nov. (Plate XXXI. figs. 12 d , 15 $ .) 



Male. Closely allied to C. argiolus, but the blue of upper surface is deeper and more violet in tint. 

 Primaries have a black margin widening towards apex. Secondaries have the costal margin 

 broadly, and the abdominal fold narrowly, black, and there is a series of black spots on outer 

 margin. Fringes white, interrupted with black at the extremities of the nervules on primaries 

 only. 



Female. Primaries iridescent blue, with very broad black costal and outer marginal borders ; the 

 inner margin is also narrowly black, and there is a short longitudinal black dash at the end 

 of the discoidal cell. Secondaries are black suffused with blue on the central area extendinff 

 to the base. ~ 



Under surface of both sexes whiter than in 0. argiolus, but the markings are very similar, except 



that the submarginal lunules are better defined than is usual in that species. 

 Expanse 38-39 millim. 



The female of C. oreas bears a slight superficial resemblance to C. nebulosa. 

 Occurs at Ta-chien-lu and How-kow at about 10,000 feet.
