Larva. — Length, 27 millimeters. Pinkish gray; dark medio- 

 dorsal pattern; spiracles black; whitish suprapedal longitudinal 

 line. 



Pupa. — Bronze-brown with lighter reflections and black dots; 

 two short white lines on the dorsum extending one-third way 

 from tail; mediodorsal white line on dorsum extending half 

 way from tail and continuing black ; suspended by the tail from 

 the food plant. 



Matsumura records this species from Hokkaido (Yezo), Hon- 

 shu, Shikoku, and Kyushu ; also, from Korea and China. I have 

 taken it from May to August, and have noticed that in Honshu 

 and Kyushu it appears to be a mountain butterfly, while in Hok- 

 kaido it inhabits the plains. As far as I am aware, no figure or 

 description of the larva has been published before.
