In the shape and markings of wings, the female of this species 

 so much resembles Z. atlilia that Mr. Wileman has described it 

 as a new variety of the latter species. When Prof. Matsumura 

 -described his new species Z. Nohiiae in this magazine it was 

 also considered by him as one of the closest allies of Z. attilia 

 though quite new to science. Lately the latter author, came to the 

 conclusion that the Z. Nohirae is by all means the female of Z. 

 fujisanus, whicb was already described by him in one male specimen. 

 This conclusion becomes now generally accepted by entomologist in 

 Japan; not only the important characters of specific value in both 

 species agree with each other, but also tliey inhabit always the same 

 region as well as in the saine season. 



Z. fujisanus is a very interesting member in the genus Zep- 

 liyruS) for it seems to me as an intermediate species which connects 

 the two distinct groups of the genus ― oricntalis ― and attilia-gioup. 

 The metallic blue colour of the wing in males represents evidently 

 the character common to all members included in the orientalis- 

 group, while the the markings found on under surface of the wing 

 are almost parallel to the common patterns of the attilia-group. 



In the female, moreover, the outline of the wing appears much 

 TOimdish as seen in Z. attilia.
