90 BRITISH BUTTERFLIES. 



by many, that a large proportion of those taken here 

 have niigrated or been blown across the Channel ; 

 though I believe it sometimes breeds here, and that 

 the caterpillars have, on one or two occasions, been 

 found in this country. 



The butterfly has been taken several times at Dover, 

 Margate, and other places on the Kentish coast ; at 

 Lewes ; Whittlesea Mere, Cambridge ; Worcester, and 

 near Bristol. 



The caterpillar, which is to be found in June and 

 September, is bluish with black spots, a pale yellow 

 line on each side, and two of the same colour on the 

 back. M. Le Plastrier reared a number of them, feed- 

 ing them on the leaves of the Wild Mignonette (Reseda 

 tutea). It also feeds on Weld (Reseda Luteola). 



The chrysalis very much resembles that of the Small 

 Garden White, and is totally unlike that of the next, 

 the Orange-Tip, with which it has been by some ento- 

 mologist united into another genus (Mancipium). 



Daplidice is a slow insect — slower than the Common 

 Whites — and it is an easy matter to catch it, when 

 recognized, which the peculiarly heavy flight might aid 

 ono in doing. 



May and August are the months in which to look 

 after this gem of the Pontia genus.
