 I have onlv two very worn specimens from Nambu, and one good specimen from Asama-yama. 



Concerning- the LYCiENID^, there are some very interesting points which may be here mentioned. 

 The first is the remarkable difference between the colour of the sexes of many of the species, forming this 

 group, and I have drawn up a table under the following headings illustrating this fact ： ―

Some of the species do not always con form to their respective headings. There are bright and dull 

 female polymorphic forms of Thecla japonica, and temperature forms of others, such as Polyommatus 

 phlxas, the male of which becomes nearly black in the summer, and Lycxna euphemus, specimens 

 of which from Yezo are bright, especially the males.
