markings agree with taxila, only tho W-angle is less perfect, and there are no blue scales on 
its short side." {Fivsen, I. c.) 
Yar. aurorina, OberthUr. " Differs from the typo in having the spots beyond the diseoidal cell 
bright yellow, similar to Z. querciis, var. hellus, and the under surface is of a golden coppery 
tint, instead of the usual silvery grey." {Obertliur, I. c.) 
The above form of the female was taken in the Isle of Askokl in the 
month of August. It is the same form as that described and figured by 
Bremer (pi. viii. fig. 2), which he considered to be the male of his taxila. 
Oberthiir also mentions a female specimen, taken at the same time and place, 
with bright blue above, as in the same sex of Z. quercus. 
Oberthiir mentions both sexes of this species, but from his remarks it is 
certain that he had before him females only, and was not aware that the male 
of taxila is green. The true male he refers to Z. smaragdina, and says that 
Hewitson's figure (which very correctly illustrates the japonica form of 
Z. taxila) represents smaragdina. The figure in question has no discal 
marks on any of the wings, and these would have been shown if smaragdina 
had been the species figured. 
The large race known as japonica, Murray, occurs only in Japan and 
Corea, but the smaller Amnrland type is also found in the mountainous parts 
of Japan and in Yesso. The phases of variation in each of these races is 
exactly similar, and the following table has been drawn up to facilitate 
reference to the difierent forms of the female : —
