W00D-WH1IE MARBLED WHITE. 95 



The caterpillar is green, striped on each side with 

 yellow ; it feeds on the Bird's-foot Trefoil, and other 

 leguminous plants. 



The chrysalis is shown on Plate I. fig. 18, and in 

 shape somewhat approaches that of the Orange-tip. 



The butterfly appears in May and August, and though 

 by no means a common or generally distributed insect, 

 is found — and sometimes abundantly — in many locali- 

 ties throughout the corutry, as far north as Carlisle; 

 some of these are here given. "Woods in neighbour-
