The larva figured (Plate II, figs. 14 and 15) was taken 

 September 26, 1900, at Yoshino, Yamato Province, Honshu, on 

 evergreen oak, Japanese name, aka-gashi (Quercus acuta 

 Thunb.) ; it pupated September 30, 1900, and a male imago 

 emerged October 5, 1900. I also found larvae of this species 

 at Kobe, Settsu Province, Honshu, in May, 1901, from v^^hich I 

 bred specimens June 7 and 19, 1901, and July 11, 1901. There- 

 fore there are evidently at least two broods in the year, the larva 

 of the first brood being taken in May or possibly earlier, and 

 the larva of the second brood in September or earlier. Mat- 

 sumura gives shii (Pasania cuspidata Cerst.) as the food plant. 



Seitz states that A. japonica is common in the spring and 

 again from August in central and southern Japan and Korea, 

 and that he caught numerous males in flowering fields as late 

 as November. Miyajima gives the time of appearance as May 

 to September for the first brood and September to April for 

 the second brood. Pryer gives September to December and 

 April. I have taken this species in Honshu and Kyushu from 

 May to October, and Matsumura records it from the same islands 

 and from Shikoku. Therefore it may be said that the species 

 occurs in Honshu, Shikoku, and Kyushu from May to the follow- 

 ing April. The late imagoes of the second brood frequently 

 appear on sunny days from November to April, flitting about 

 flowers or the branches of the food plant (evergreen oak). 

 Pryer records the fact that the species hibernates. Miyajima 

 also records it from the Loochoo Islands (Ryukyu). In a note 

 written in a copy of Pryer's Rhopalocera Nihonica which I 

 obtained from the Rev. W. Andrews, of Hakodate in Hokkaido 

 ( Yezo) , it is stated that japonica occurs in Hokkaido, but no date 

 of appearance is given. No author, however, appears to have 

 recorded it from that island, and Matsumura distinctly states 

 that it does not occur there. 



Larva. — The larva may be described from my original figure 

 as grayish white tinged with yellow ; dark mediodorsal, longitud- 

 inal stripe edged broadly with yellow; pale subdorsal and sub- 

 spiracular longitudinal stripes. Length, 19 millimeters.
