Ver}- common all over Japan and Corea. Amongst a large series 

 I took some very fine aberrations.

This species is recorded from Possiet Bay, N.E. Corea. 



120. Pararge achine, Scop. 



P. achinoides,Ji\xi\. Cist, Ent. ii. p. 283 (1877). 

 Occurs in Gensan, and also in Central and Northern Japan. The 

 form is the same as that which occurs in Ainurland.

 Lasiommata marginalis, Motsch. Bull. Mosc. 1866, i. p. 190. 

 I found this species in Yesso, and Mr. H. Pryer has it from 

 Yamato.

 This is not a common species. I have taken it at Gensan, Hake- 

 date, and it occurs on the volcano Assamayana in Central Japan. 



124. Pronophila schrenkii. 



P.schrenkii, Men. Schrenk's Reise, p. 33, t. iii. fig. 3. 



Common in Gensan, North-west Japan, and Yesso. It flies in 

 dense underwood, and is hence rather hard to take, and seldom in 

 fine condition. The Japanese specimens are larger and paler than 

 those from the Amur and Corea.
