 A series of female specimens is contained in the collection of the 

 Station. They are much larger than the typical forms found in the main 

 island of Japan ; some variation in the wing-marking is also noticeable. 

 The absence of male specimen in the collection is possibly due to the 

 speedy flight of the moth, and not to its rarity. I have however nowhere 

 met with the moth during my stay.
