In this connection I may observe that I have three semi- 

 apterous female forms of this species, taken, whilst seated on 

 their cocoons, from which they had apparently just emerged, 

 by my collector on October 28, 1898. This proves that the 

 curious dimorphic form of the female is not the result of breed- 

 ing, but that it is due to natural causes. It would be interesting 

 to elucidate the reasons for this dimorphism of the same sex 

 which, so far as I am aware, does not occur in any other species 

 of the genus Orgyia in Japan.
