Coll. M. Fenton. 



This is an interesting and well-defined new species. 



Araschnia oBscuRA, Fcntou. 



Allied io A. fallax, O. Janson (Cist. Ent. 1878, p. 271). Male above 

 soot-black : primaries with four short narrow transverse lines in the 

 cell, and one below the median vein near the base, pale ochreous ; 

 the transverse interrupted band on the disk extending quite to the 

 costal edge at one end, but only to the submedian vein at the other, 

 very pale ochreous ; four spots in a curved row near the apex, the 

 first and second, and a sniall linear spot about the middle and close 

 to the margin, pale ochreous, the third (the smallest) and the fourth 

 (the largest) and a small spot between the second and third median 

 veinlets pure white ; no irregular submarginal lunular reddish-sienna 

 spots : secondaries produced at the middle of outer edge ; no undula- 

 ting reddish-sienna lines ; fringe with white sinuations interrupted by 

 black at the end of the nervures. Below pale ochreous ; the irregular 

 marks at the base reddish chocolate ; the apical third occupied by a 

 broad band of the same colour bordered inwardly with black, inter- 

 rupted by the nervures : primaries with an additional small white 

 spot in the band, between the first and second median veinlets ; the

Forest-lands in Hokkaido, August. Coll. M. Fenton. 



I have not examined the type of this species of Mr. Fentou's ; 

 but, from a photograph which he has shown me, I should judge it 

 to be perfectly distinct. 



Vanessa lunigera, Butler. 



Alhed to V. fentoni, but altogether duller in colour ; the black 

 spots above considerably larger ; the lunate subconfluent spots on the 

 external area of secondaries replaced by a series of small lunules : 

 under surface with all the bands considerably darker and broader, 

 the silvery white J-shaped marking on the secondaries replaced by 

 a J-shaped character. Expanse of wing 2 inches 5 hues. 



N. Iburi, Hokkaido, July. Coll. M. Fenton. 



This species has the costal margin of the primaries more produced
