Staudinger gives the following description of the larva of 

 C. albomaculata, which agrees best with my original figure of 

 the larva, form 2 (Plate II, fig. 6). 



The larva of albomaculata, of which Christoph sent me a very good 

 prepared specimen, is very different from that of potatoria, especially 

 differing also from those of potatoria of the Amur region of which I have 

 two good specimens from Dorries. These are as dark as the darkest larvae 

 found in Europe in which sometimes the yellow spot-stripes "on the upper 

 side appear very strongly marked almost like stripes. The larva of albo- 

 maculata has large, quadrate, orange-brown dorsal spots, edged around with 

 white, on which stand four pairs of black hair tufts which are much shorter 

 than in potatoria. Laterally (from the spiracles) and below the larva is 

 brownish, also the legs. Here, in potatoria everything is dark, only later- 

 ally are there small orange stripes which are clothed below with white, or 

 yellow, woolly hairs." 



Grtinberg ^® describes the larva of albomaculata as follows : 



Larva with large orange-brown dorsal spots edged with white, and four 

 tufts of hair at each side on segments 4 to 10 respectively, these being 

 still shorter than in potatoria; laterally and ventrally brownish. Habits 

 as in potatoria, likewise the shape and color of the cocoon. 



Sasaki -^ gives descriptions and figures of the larva, the 

 cocoon, and the male imago. He says that the larva, which 

 feeds upon bamboo, appears about the middle of May. It is 

 full-grown in June, and the imago emerges at the end of the 

 same month. 



Local distribution. — Common in Hokkaido (Yezo) and Hon- 

 shu. Matsumura records potatoria, with which he includes 

 albomaculata as a variety, from the same islands. I have in my 

 collection six males and ten females of albomaculata captured 

 and bred at the following localities: Tokyo, Musashi Province, 

 and Kobe, Settsu Province, both in Honshu, and Hakodate, 

 Oshima Province, Hokkaido, two males and nine females bred 

 from larva of form 2, in June, July, and August. Yoshino, 

 Yamato Province, Honshu, and Hakodate, Hokkaido, four fe- 

 males taken in June and July. Nikko, Shimotsuke Province, 

 one female, taken in August. 



Time of appearance. — Larva, May, June, July?, August, and 

 September; imago, June to August. 



General distribution.- — Eastern Siberia (southern Amurland) ; 

 Korea; Japan. (Griinberg.)
