120 BRITISH BUTTERFLIES AND MOTHS 



The larva of Art axerxes (which, through the kindness 

 of Mr. Logan, I have had an opportunity of examining) 

 is green, with a red line on each side ; the dorsal line is 

 dark green ; the bristles are whitish, but on the second 

 segment brown ; on the back of the second segment is a 

 pale spot, and there is one on each side of the back of 

 the twelfth segment at the termination of the reddish 

 lateral line ; the head is shining black. This larva was 

 feeding on Helianthemum vulgare (Common Sun Cistus), 

 towards the end of May, and would appear in the perfect 

 state in June and July. In the south of England Agestis 

 is on the wing in May and August.
