The named varieties and aberrations of this 

 species are numerous, though some of them are 

 founded on very slight differences. There seem to 

 be two separate racial forms, one as in the type, 

 with a very broad border and with light-coloured 

 wings ; and the other smaller in size, with a much 

 narrower border and a tendency to orange coloura- 

 tion.
