CAMBEBWELL BEAUTY. 69 



The caterpillar feeds on the willo'w and birch, and is said to be 

 found on the topmost branches. 



This butterfly varies in the expanse of its wings from a little under 

 three inches to three inches and a half. The fore wings are of a fine 

 dark rich claret-colour, margined with dull white, or yellowish. Inside 

 the margin is a row of blue spots, on a velvet black ground. The 

 hind wings are of the same dark claret ground-colour. 



Underneath, the wings are ash brown, with a great many slender 

 transverse black lines; the white margin and spots shew through, as do 

 the bar and the blue spots, but only faintly, if at all. 



The caterpillar is gregarious, black in colour, with spots on the 

 back, and some of the legs of a red colour. 



The chrysalis is dull black, with fulvous spots, and dentated in 

 appearance. 



The engraving is from a specimen in my own collection.
