THE BATH WHITE. 41 



brood of the caterpillars upon a bunch of watercress placed in 

 water and stood in a sunny window, but he does not refer to 

 anything peculiar about the butterflies resulting therefrom. 

 t He states, however, that from eggs laid in June the earliest 

 butterfly appeared within a month, and the remainder by the 

 middle of August, only one remaining in the chrysalis until 

 the following June. 



Caterpillars may be found in June and July and in August 

 and September. 



The chrysalis is green in colour, and the raised parts are 

 yellowish and brown. This is the most frequent form, but it 

 varies through yellowish to buff or greyish, and is sometimes 

 without markings. 



Generally distributed throughout the British Islands, but its 

 range northwards does not seem to extend beyond Ross. 



In Europe it is generally common, and extends through 

 Western and Central Asia to Siberia, and, according to Leech, 

 is found in North Japan. In Amurland and Corea it is repre- 

 sented by the form orientis, Oberth. It occurs in North- West 

 Africa, the Canary Isles, and the Azores. In America it is 

 found in the Northern States and in California. 



The Bath White (Pieris daplidice). 



, The Bath White (Plate 14) is such a rare visitor to this 

 country, that any one who captures a specimen may congratulate 

 himself on the event. During the whole of the last century not 

 more than sixty specimens seem to have been recorded as taken 

 in England, and ten of these were captured between 1895 and 

 the present time. Nearly all of these were netted on the south 

 or south-eastern coast, and in the months of July or August, but 

 chiefly the latter. The occurrence of specimens in May or Tune 

 appears to be quite exceptional. 



Although it might be passed over for a Green-veined White,
