X, D, 6 Wileman: Notes on Japanese Lepidoptera, III 359 



larva, which in Gifu, province Mino, Honshii, feeds on Momo (Peach) 

 and Sakura (Cherry), first appears there in May and June. In June 

 and July it is full-grovi^n and spins its cocoon. The imago appears from 

 the end of September to the middle of October. 



This agrees with my experience, as on June 11 and 23 there 

 were very few larvae to be found at Yoshino, but many cocoons, 

 whereas on May 15 I found the larvae in profusion. One larva 

 which I bred pupated as late as August 15. 



I have never myself seen the imago flying, but my Japanese 

 collector captured many specimens at Yoshino in August and 

 September and some in Kyushu in October. 



Sasaki states that the imago appears at the end of July, but 

 Nagano has never seen it flying at Gifu in this month, as it does 

 not appear there before September. The examples of this 

 species in the Nawa collection at Gifu, numbering over one hun- 

 dred specimens, were all taken there between the end of Sep- 

 tember and the middle of October. 



Nagano states that he bred young larvae from a batch of eggs 

 laid the middle of October. These eggs were placed in a moder- 

 ately warm greenhouse and hatched at the end of October. 

 He questions whether this would occur in a state of nature, as the 

 rapid incubation may have been due to the unusual warmth. If 

 it is their usual habit to hatch at that time of the year, they 

 would suffer from scarcity of food and, therefore, probably would 

 hibernate in the larval state. If these eggs were forced by the 

 heat of the greenhouse and it were unnatural for them to hatch 

 at that time, they would probably hibernate in the egg stage. 



Larva. — The following is a description of the larva taken from 

 one found on May 15, 1901 : Length, 29 millimeters. Light 

 greenish yellow ; head retractile, almost hidden by deep skin fold 

 of second segment, black, smooth, shiny, a black spot on each 

 side of mandibles ; two black submedian spots near dorsal margin 

 of segment 2, and one black spot on each side of same segment; 

 from segment 3 to the anus there extend five violet-brown longi- 

 tudinal stripes : one mediodorsal, two midlateral, and two spira- 

 cular. Spiracles black; the dorsal region has minute, paired 

 black bristles on each segment situated on each side of the medio- 

 dorsal line and also a minute bristle issuing from ventrad of the 

 midlateral stripe on each segment. Ventrad to the spiracles and 

 the spiracular stripe there is on each segment, from 3 to anus, 

 a single, slender, long black bristle, feathered somewhat like the 

 antenna of a Procris, those on the anterior and posterior seg- 

 ments being rather longer. On the dorsum of segment 2 there 

 are also paired black bristles, one on each side of the black spot ;
