The larva figured (Plate I, fig. 9) wafe taken May 20, 1901, at 

 Kobe, Settsu Province, Honshu, on dwarf oak, Japanese name, 

 kunugi (Quercus serrata Thumb.) ; a female imago emerged 

 from the pupa of this larva June 8, 1901. 



Larva. — The following description is taken from my original 

 figure: Length, 23 millimeters. Pale green with faint yellow 

 subdorsal oblique streaks on the side; dark spiracles; spines 

 on dorsum highly acuminate on segments 5, 6, 7, and 8; a 

 whitish longitudinal subspiracular line running from head to 

 tail. Miyajima states that the larva of this species feeds on 

 ko-nara, a species of dwarf oak {Quercus glandulifera Bl.) ; Mat- 

 sumura gives kashiwa {Quercus dentata Thunb.). 



The imago generally flies among dwarf oaks in the early 

 morning and also again in the evening from 5 o'clock on and is 

 very regular in its time of flight, Japanese professional col- 

 lectors call it toki (time, hour) on account of its punctual habits. 



Matsumura records it from Hokkaido (Yezo) and Honshu 

 and from eastern Siberia (Ussuri). I have taken it in Hok- 

 kaido and Honshu from May to August. It does not appear 

 to have been recorded yet from Shikoku and Kyushu. It is 

 abundant in the Bukenji Woods, near Kanagawa, Yokohama, 

 where dwarf oak is plentiful.
