COMMA. 79 



The clirysalis is pale brownish red, and spotted with gold. It 

 remains in this state about fourteen days. 



Mr. Westwood observes how this species is subject to an 

 extraordinary variation in the form of its wings, the incision 

 in the outer margin of the fore wings being in some specimens 

 so deep that it forms nearly a semicircle, whilst in others it 

 is scarcely more than a sextant, the other indentations being 

 equally varied. 



I once had a singular variety taken near Doncaster, and 

 which I gave to J. C. Dale, Esq., in Avhich all the black spots 

 on the fore wings were run into one large patch. 



The plate is from specimens in my own collection.
