Three forms of the larva are figured. 



Form 1. — Laterally yellowish in color; length, 63 millimeters 

 (Plate II, fig. 4). This larva was taken at Yoshino, Yamato 

 Province, Honshu, in September (figured September 12), 1900, 

 on kaya, a species of reed grass (? Torreya nucifera S. & Z.). 

 The larva died, so that no imago was bred from it. I have 

 observed this form on several occasions and think that it is 

 merely a light form of the larva of albomaculata, although I 

 failed to breed it. One often sees the larvse of this species 

 basking in the sun on mountain paths, having crawled down 

 from adjacent bamboo grass for a tour of inspection ; they vary 

 much in shades. 



"" Matsumura gives this name to both C. potatoria Linn, and C. alboma- 

 culata Brem., as he regards the latter species as a variety of potatoria.
