lighter coloured than those of A. sjjlvatica, and there is a conspicuous sexual 
brand on primaries similar to that oiA. thaumas. The females are exceedingly 
like those of A. sylmtica, but the pale markings are more distinctly defined. 
On the under surface both sexes are very similar to A. sylvatica, but the malr 
is distinguished by the sexual brand as above, and both sexes of this species 
have the brownish patch towards outer angle of primaries much smaller, and 
it does not extend to inner margin as in A. sylvatica. 
Occurs in the mountainous parts of Central Japan, in Yesso, and at 
Gensan, in Corea. Dorries found it at Baranowka and in the district of 
Sutschan. 
In Western China my collectors met with specimens at Wa-shan and 
Ta-chien-lu, which only appear to differ from Japanese examples in beinii- 
slightly smaller (Plate XL. fig. 4, c? ) ; but at Chang-yang, Central China, a 
remarkable form, for which I propose the varietal name astigmata, occurs 
(Plate XL. fig. 7, <5 ), in which the sexual brand of the male is entirely 
wanting. In other respects this form does not differ from the type, except in 
being rather more suffused with black, xis I thought this insect might be 
the male of a distinct species, I had the genital armature prepared and 
mounted for microscopical examination, and find that it is identical in shape 
and structure with that of ^. leonina from Western China.

" Antennse short, less than half the length of costa ; club short, robust, terminal crook exceedin'tly 
minute. Palpi as in HyJepldla. Neuration as in Hylephila except that vein 2 of the fore 
wing is much nearer to the base of the wing in the male, and vein 7 of the hind wing is 
slightly nearer the base of the wing in both sexes ; the stigma on the fore wing is very 
similar to that of Hylephila, except that it entirely fills the angle at the bifurcation of vein i', 
while in Hylephila the discal stigma crosses the interspace beyond the origin of vein 2.
