also are decidedlj- smaller, as ia L. argiolus, and have the suhmarginal lunules and spots below 
much less strongly defined. Expanse of wings, J 30-34 millim. Jinchiien, "W. Corea." 
{Butler, I. c.) 
All my specimens of L. art/wins from Eastern Asia differ from the Eiu'o- 
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 with Z. kasmira 
Moore {=ccelesUna, KoUar), Proc. Zool. Soc. Lond. 1865, p. 503, pi. xxxi. 
fig.l, 6). 
Pryer 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 miUim., and in the 
width of the black marginal border of primaries there is considerable 
diversity. 
The Indian L. huguelii, Moore, does not appear to me to be specificaUv 
distinct from L. argiohis, and I think that it, and also L. coeleatina, KoUar, 
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 Afiica. 
Cyaniris oreas, sp. nov. (Plate XXXI. figs. ]2 c? , 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 exteudin"- 
to the base. 
Under surface of both sexes whiter than in 0. argiolus, but the markings are very similar, except 
that the suhmarginal 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. nehulosa. 
Occm-s at Ta-chien-lu and How-kow at about 10,000 feet.
