NOTES ON VARIATIONS IN SOME JAPANESE 

 LEPIDOPTERA. 



By Charles Ishikawa, University of Tokio, Japan. 



Having had a summer's tour in the southern extremities of 

 Hokkaido, I caught a few species of butterflies which are more 

 or less interesting, as the}' present peculiar local variations in 

 comparison with those found on the main island. These species 

 are : 



1. Araschnia Fallax. O. Janson. 



This species is common in the northern part of the main 

 island, abounding in the mountainous districts. A species very- 

 much allied to this was found by Mr. Fenton in the shady 

 wood near Sapporo, Hokkaido, and described by him under the 

 name of ^. Obsciira. 



2. LeUCOPHASIA AmURENSIS,. Meuetries. 



The representative of this species (figures i, 2) was found 

 in Hokkaido, with rounder wings and paler apical patch. (Figs, 

 3,4.) 



Mr. Fenton has kindly described this species for me as fol- 

 lows : 



LEUCOPHASIA Morsel Fenton. 



Allied to L. Amurensis, Menetries. 



Wings rounder; not produced at the apex ; the black apical 

 patch, lighter. 



Average expanse of 



L. Amurensis, $ , i" 11 j4"'', ?, 2" o^'". 

 L. Morsel, 6,1" 11'"; ?, 2" o'". 



Together with the roundness of the wing in the Hokkaido 

 species, it will be seen that the fourth and the fifth subcostal
