in colour, is of uniform width throughout ; the fulvous submarginal line is 
uninterrupted and parallel with the outer margin. The design of the under 
smiace separates this species at once from its allies. 
Seeing how closely fallax resembles in'orsa, and that both are summer 
insects, it seems highly probable that the former may have a spring brood as 
well as the latter. 
^Vhen dealing with far fewer specimens, I considered that fallax, Janson, 
was the second brood of ^. lurejana; but if it were so fallax would surely 
occur in either Amurland or China, instead of being confined, as it appears 
to be, to Japan. The same objections apply to prorsoides being a form 
of fallax. The specimens previously recorded by me from Corea as 
A. fallax I have now determined to be only strongly marked examples of 
jiTorsa iorm. of A. levana. Dr. A. Fritz (Zool. Anzeiger, 1890, p. 13) 
discusses Japanese Araschnice, but as he does not clearly indicate the various 
forms, I am unable to follow his remarks. 
Occurs at Hakodate, Yokohama, and Oiwake in Japan.

" Above most like the European form porima, Ochs., but has the broad band on the fore wing 
above in a straight line with that on the hind wing, and the outer bands paler and straighter 
than in European or Japanese specimens. Beneath, the general coloration and markings 
resemble burejana more than porima, but this species is paler than either, and has a lilac 
patch round the white marginal spots on both wings as in burejana. In size it is constantlj- 
much larger than European and rather larger than Japanese specimens ; the margin of the 
hind wing is also much more scalloped out between the veins." (Ehves, I, c.) 
A. prorsoides is nearest allied to A. fallax, Janson. 
Alpheraky [I. c.) figures a specimen of this species taken by Potanine in 
North-western China under the name of strigosa, Butler, an error he would 
have avoided if he had had the opportunity of examining Butler's type. 
The figure represents a form of A, prorsoides^ Blanch.
