Two larvse are figured (Plate II, figs. 10 and 11). One (fig. 

 11) was taken in August (figured August 22), 1900, at Yosliino, 

 Yamato Province, Honshu, from wliich no imago was bred, and 

 one (fig. 10) was taken in June (figured June 7), 1902, at Hako- 

 date, Oshima Province, Hokkaido (Yezo). The food plant is 

 unknown, as no notes were taken. 



From the larva taken in June, 1902, a male imago emerged 

 August 26, 1902. In this specimen the white markings on the 

 forewings are slender (aberratively reduced) and are for the 

 most part replaced by the brown spots. As the specimen is not 

 at hand, I am unable to say whether it is referable to phseosorna 

 Butler, which is the normal form in Japan. 



Larva. — Velvety black; each segment having a number of black shining 

 tubercles, from which proceed very long hairs, those on the dorsal area are
