Distribution : Nepal (new locality), China, Japan. 



The <$ has two small black markings near the wing base besides a large distal 

 costal black marking. This type of wing pattern is the same as in the original form 

 (China) (Tan, Hsu, and Sheng, 1949). In the Japanese form, however, the basal 

 black markings are absent or very weak except in a form from the southern island, 

 Yakushima, Kyushu, collected by the author in summer, 1962.
