RHOPALOCERA XIHONICA. 29 



This species is common about Yokohama. The two sexes show a very remarkable differentiation in 

 coloration. The specimen figured is a male.

A. paphioides, But. 



Localities CJyama, Asamayama, Kanosan, Fujisan, Yezo.

This is a mountain species. I have taken it once, however, at Yokohama.

A. lysippe, Jan son. 



Localities Yokohama, Nikko, Yezo. 

 Time of appearance September. 



Mr. Ehves remarks that this species comes very near A. laodice, Pall. It looks like a hybrid, but the 

 specimens in my possession are as yet too few to enable me to give a decided opinion on the subject. 



Family DANAID^. 



99- Danais tytia, Gray. (PL 8, fig. 9.) 



Localities Yokohama, Fujisan, Yaniato, Oyama, Atami, Kanosan, Yezo. 

 Time of appearance May, August, September. 



This is scarce about Yokohama, but I generally see two or three every year. It is much more 

 abundant on the mountains, and I have taken as many as five specimens, at one sweep of the net, on the 

 summit of a mountain in Yamato, near Yoshino, on the path leading to O-mine San-jo-san.
