The Large White is very common throughout Europe, and 

 also, according to some' authors, in the north-cast of Africa, and 

 even in Eastern Asia and Japan. 



It is a very abundant species in this country, and its cater- 

 pillar causes much damage in gardens in dry seasons, which are 

 favourable to their production. 



The perfect insect occurs about the middle of May or earlier, 

 if what we may now call the "Queen's Own" days shine npon 

 it in its hidden existence. A second brood appears in July. 



The eggs of the first brood are laid about . the end of May, 

 and the caterpillars are hatched the beginning of June. They 

 turn into the chrysalis state at the end of that month, and the 

 fly emerges in about a week or a fortnight, according as the 

 season is less or more favourable to its development. The eggs 

 of the second brood produce caterpillars which turn into 

 chrysalides in the course of the autumn, and remain in that 

 state until the following Maj*. 



The caterpillar feeds on the common cabbage, f Brassica 

 olcracea.J 



The expanse of the wings varies ordinarily in different in- 

 di^'iduals, from two inches and a half to two and three-quarters
