1899] CABBAGE BUTTERFLIES. 3 



The Small White is about two-thirds of the size of the Large White 

 in expanse of the fore wings, this being about two inches, and the 

 Large White from two and a half to three inches. The caterpillars 

 are velvety when full grown, green or dull green, much paler below, 

 with a yellow line along the back, and a faint yellow line with a row 

 of yellow spots along each side. The chrysalids are variable in colour; 

 pale flesh brown, dusky drab, or greenish, are some of the colours 

 named ; some with a freckling of black, some finely powdered over 

 the back with black, and some with " a rosy pink" or dull green tinge 

 suffused all over them. The eggs are laid singly, and (so far as yet 

 recorded) beneath the leaves ; the colour " very pale greenish yellow," 

 gradually becoming of a more decided yellow ; the shape and also 

 attachment by one end the same as those of the eggs of P. brassiccn, 

 the Large White. 



The Green-veined White Butterflies are so called from having 

 broad greenish margins to the veins of the lower side of the hind

wings, which are otherwise of a sulphur or pale yellow, and may thus 

 be distinguished from the Large White, of which the under sides of the 

 hind wings are of a dull palish yellow speckled with black, and those 

 of the Small White, which are similarly yellow on the under side, but 

 thickly speckled with black towards the base. The caterpillars when 

 full-grown are velvety, or in more detailed description " the whole 

 skin, including the head, set with sharp points, all furnished with short 

 hairs; the colour a full green," somewhat of a paler greyer green 

 below ; a darker green line along the back, and an indistinct yellowish 

 green line along each side, on which are black spiracles, each in a 

 round yellow or reddish spot. The chrysalids are mostly pale greenish 

 or of a pinky buff, variously marked with yellow and spotted with 

 brown, and of a brown colour at the two ends. Eggs pale green, 

 becoming paler, otherwise of the shape, and placed like those of the 

 Small White (P. rapes).
