primaries is flaxen-grey, -witli the usual black dots surrounded -witli white ; the secondaries 
are thickly powdered with silvery green, or sometimes bluish, scales from the base of the 
wing as far as the submarginal line, which is composed of small reddish dots placed between 
the nervules ; the outer margin and fringes are pure white. 
Expanse 30 millim. 
Of this species, which was first discovered by Monseigneur Felix Biet at 
Ta-chien-lu, I have specimens from almost all the localities in Western China 
visited by my collectors, and also from How-kow in Thibet. It appears to 
be on the wing from May to August.

" Expands 1 to 1-12 inch in the typical form. Fringe of all the wings white. The male has all 
the wino-s shining light blue above, without discoidal spots, with a well-defined dark brown 
hind marginal border, and on the hind margin a row of dark spots. The female is brown ; 
all the wings with a light orange hind marginal band and black spots ; fore wings with a 
black discoidal spot. Underside pale grey in the male, brownish grey in the female, with 
the usual orange bands and rows of ocellated spots ; fore wings with two basal spots ; the 
bases are tinged with pale blue." {Lang, I. c.) 
There is an unnamed specimen in the ]Vational Collection from Chemulpo, 
N.W. Corea, which I certainly believe to be this species. It agrees exactly 
with typical L. eros on the upper surface, but the orange marginal band on 
under surface of secondaries is rather brighter and broader. Alpheraky 
(Rom. sui- Lep. v. p. 78) records a specimen taken in the Bourkhane-Bouddha 
Mountains in N.E. Thibet, and states that it differs from the ordinary type 
in the paler under surface, the narrower black margins on the upper surface 
of the wings, and the absence of black submarginal spots, which are con- 
fluent with the marginal border of secondaries in the type. 
Bremer records specimens taken by Eadde in the neighbom-hood of Lake 
Baikal, Dahuria, and from the Bureja Mountains. Staudinger, however, 
(Rom. sur L^p. v. p. 162) states that the species has never been subsequently 
received from Amurland or Trans-Baikal and considers that Bremer's records 
must be incorrect. He adds that he has only received specimens of L. eros 
from Central Asia and the Altai. 
According to Lang this species occurs in mountain pastures in Switzerland 
and the Pyrenees from June to August.
