livbernaculmn soon after its emergence, and remains quiescent until the following March, when it is 

 awakened by the first warm day and may then be seen depositing its eggs on the unopened buds of the 

 Cellis. The pupa is suspended by the tail after the manner of a Vanessa. It varies considerably in 

 markings and size.

This most beautiful butterfly is very capricious, and, although not uncommon in Tokyo, is almost un-

 dozens in a day without being able to secure a single specimen. It is quite fearless, and the male has a 

 Favourite stand, often on the summit of a tall tree, from which it sallies forth and attacks any passing bird 

 or insect, returning to its perch after it has chased the intruder away. Almost the only way to obtain it is 

 to find an oak or chesnut which has been attacked by the boring Cossus or Hepialus, the fomenting sap 

 from their burrows being very attractive to it. Each individual generally has its favourite tree to which 

 it descends to suck the flowing sap and fight the other insects which also crowd such attractive spots. 

 Within the space of a few feet on the bole of a tree it may often be seen in company with two or 

 three enormous Hornets and a crowd of Lethe sice/is, Stag, and other Beetles, which it buffets with
