The larva figured (Plate I, figs. 12 and 13) was taken June 

 14, 1902, at Hakodate, Oshima Province, Hokkaido (Yezo), on 

 dwarf oak, Japanese name, ko-nara {Quercus glanduUfera Bl.) ; 

 it pupated June 21, and a male imago emerged, date unrecorded, 

 which I identified at the British Museum (Natural History) as 

 Zephyrus orientalis Murray. Another male pupated at Kobe, 

 Settsu Province, Honshu, May 11, 1901, and emerged June 1, 

 1901. 



Larva. — Seitz describes the larva as ashy gray, with darker 

 markings, the segments projecting laterally; lives until June on 

 oak. The following description is taken from my original figure : 

 Length, 20 millimeters. Ashy-gray; mediodorsal longitudinal 

 black line edged by white lines on each side ; darker lateral oblique 

 streaks edged with white ; segments on dorsum projecting acumi- 

 nately, slightly hairy; the segments projecting laterally above 

 legs. 



Pupa. — The pupa is attached by a silken tail pad and abdominal 

 girdle. 



Miyajima states that in Japan the larva feeds on evergreen 

 oak, Japanese name, aka-gashi (Quercus acuta Thunb.). 

 Matsumura and Seitz record the species from Hokkaido (Yezo) 

 and Honshu and also from Korea, central and northern China, 

 and eastern Siberia (Amurland). Matsumura gives kashiwa 

 (Quercus dentata Thunb.) and miyama-hannoki (Alnus viridis 

 var. sibirica Rgl.) as food plants of the larva. I have taken it 

 at Hokkaido, Honshu, and Kyushu from June to July. Pryer 

 records it in Japan on the plains from May to July and on the 

 mountains from July to August. Leech states that it occurs 

 plentifully all over Japan and at Gersan, Korea, from the end of 

 June to the beginning of August.
