PALE CLOUDED YELLOW BUTTERFLY. 107 



gin : the under wings dull orange, with a large and 

 small silvery spot in the centre, cinctured with rust- 

 red, and a curved row of small black spots. The 

 fringe of the wings and the antennae are rose-red. 



The caterpillar is green, with two white lines on 

 the sides, each segment mai'ked with two irregular 

 transverse series of black spots. (Plate III. fig. 2.) 

 Its appropriate food is said to be the Coronilla varia, 

 but in this country it must often content itself with 

 other fare, and probably has recourse to different kinds 

 of diadelphous plants. The butterfly is considerably 

 rarer than C. ediisa ; and, like that species, is found 

 chiefly on the sea -coast in the south-east corner of 

 the island, as in Kent, Sussex, and Suffolk. There 

 is a pale variety, nearly pure white, of which examples 

 of both sexes have occurred, chiefly in the vicinity 

 of Dover. Indeed, the insect may almost be said 

 to be a maritime fly, so rarely has it been noticed at 

 any distance from the sea-coast.
