Green-Veined White 



But the caterpillars are very different in appearance. 

 In this species the colour is a soft velvety green, with a 

 faint yellow line down the back. Stretched at full 

 length on the midrib of a cabbage-leaf, it is by no 

 means a conspicuous object, and may be quite easily 

 overlooked ; but if you see the leaves riddled with 

 holes, and find excrement lying between them and at 

 the base, don't cease looking until you find the culprit, 

 sometimes deep in a cabbage, or on the back of the 

 outer leaves. 



Other caterpillars besides those of the Large and 

 Small Whites may be present in force, notably those of 

 the Cabbage moth (Mamestra brassic*}, large stout 

 caterpillars varying from green to black ; they are far 

 too numerous, so have no compunction about destroy- 

 ing all you find. The caterpillar is apt to lose its 

 colour in preserving, as is the case with all green 

 caterpillars. 



GREEN- VEINED WHITE (Pieris napi\ Plate I., Fig. 5. 

 Unlike the last two species, this White is more often 

 found in the country than the town, and in my experi- 

 ence it is only a casual visitor to suburban gardens. I 

 have never found the caterpillars there. 



To distinguish it from the last species it is only 

 necessary to examine the under side, where both fore- 

 and hind-wings are strongly veined with greyish-black, 

 the female particularly so. On the upper side the veins 

 are distinctly marked, but the line is finer. 



In a rather wet meadow where Ladies' Smock abounds 

 in early June, I have seen this butterfly in profusion,
