area thickcrj the submarginal pale spots whiter, the secon- 

 daries with a black spot on the radial instead of on the sub- 

 costal interspace, thus making an uninterrupted series of four 

 spots ; the apical area of primaries and the whole ground- 

 colour of the secondaries dull olive-green ; the silver spots on 

 the primaries better formed, and those on the secondaries 

 larger than in Yokohama females, although decidedly smaller 

 than in Nikko females of A. nerippe. Expanse of wings, 

 S 3 inches, $ 3 inches 4 lines- 

 Two males, Posiettc Baj, N.E. Corea ; one fennile, Hako- 

 date. 



The form of this species is somewhat different from that 

 oi A. nerippe (seven fine examples of which are before me), the 

 wings being somewhat more elongated and the costa of prima- 

 ries consequently less arched.

Differs from the European type in its duller and more smoky 

 colouring and larger black spots on both surfaces ; it is, how- 

 ever, of the same size, and therefore considerably smaller than 

 'A. rahdia, from which it differs also in its duller coloration.

We have the male of this form from Yesso.

^ . Allied to B. selene, but larger, and with all the black 

 markings on both surfaces considerably larger and broader, 

 more like those of Argynnis oscari/s, the ground-colour richer
