76 CAMBERWELT, BEAUTY. 



The caterpillar feeds on the willow and birch^ and is said to 

 be found on the topmost branches. 



This butterfly varies in the exj)anse 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 bhick ground. The hind wings are of the saine 

 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.
