Sagami Province, Hiratsuka, April (Wileman) . Matsumura 
records it from Hokkaido and Honshu. 
Time of appearance. — Larva, May, June, July ? and August; 
imago, March, April, and May. In Yokohama and Tokyo, Hon- 
shu, the larva is found in May. It pupates in June and lies 
until March of the following year, the earliest emergences taking 
place about the middle of March. In fact this species is one of 
the earliest of the Japanese moths to appear in the spring. It 
is often to be taken at rest on the trunks of pines or oaks. The 
larva taken at Hakodate in August, from which my original 
figure was drawn, was exceptionally late in the season owing 
to the more northern latitude of Hokkaido. 
General distribution. — Japan. Is a northern form of wallichii 
Gray ( spectabilis Hope). (Seitz.)
