markings agree with taxila, only the W-aiiglo is less perfect, and there are no blue scales on 

 its short side." (Fixsen, I. c.) 



Var. aurorina, Oberthiir. " Differs from the type in having the spots beyond the discoidal cell 

 bright yellow, similar to Z. quercus, var. bellns, and the under surface is of a golden coppery 

 tint, instead of tlie usual silvery grey." (Oberthiir, I. c.) 



The above form of the female was taken in the Isle of Askold 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. 

 Obertliiir 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 Avas not aware that the male 

 of taxila is green. The true male he refers to Z. smaragdina, and says that 

 He^Wtson's figure (which very correctly illustrates the japonica form of 

 Z. taxila) represents smarar/dina. 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 Amurland 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 different forms of the female : —
