Several specimens from Yokohama in Fryer's collection. 

 I captured examples at Nemoro in the beginning of August, 

 and have received specimens taken in June and July from 

 Chang-yang, Pu-tsu-fong, Che-tou, and the province of 

 How-Kow. 



The typical and marmorata forms both occur in Japan and 

 China. 



Among the Nemoro specimens are two fine varieties ; one 

 of these is a very pale modification of the marmorata form 

 and the other approaches var. thingvallata. 



Distribution. Europe ; Japan ; Yesso ; Central and 

 Western China.
