122 BRITISH BUTTERFLIES. 



The inmost portion of all the wings is a deep rich 

 chocolate brown, then comes a band of black, including 

 a row of large blue spots, and succeeded by an outer 

 border of pale yellow tint, partially dappled with black 

 specks. 



The caterpillar feeds on the willow (which accounts 

 for its former appearance in Camberwcll). It is thorny, 

 black, with white dots, and a row of large red spots 

 down the back. 



The chrysalis is very angular, and blackish with 

 tawny spots. 



The butterfly comes out of the chrysalis late in the 

 autumn, and is seen from August till October; but 

 a great proportion of those observed in this country 

 have survived the winter, and have been seen abroad 

 again in the spring. It lias been frequently seen feast- 

 ing on over-ripe or rotten fruit, and at such times may 

 be often surprised and captured with ease.
