continued to feed from August, right through the winter, 

 up to the end of April ; that is to say, some of them did, 

 for the slices of carrot were always eaten, more or less, 

 even during severe weather. They were kept in two large 

 flower-pots, under an open window facing the north, and 

 led an entirely subterranean life, the four inches of earth 

 in the pots being honeycombed by their burrows. I often 

 looked at the pots after dark, but never saw any larvae on 

 the surface, except once when their food was short, and a 

 few were wandering about looking for more, when, on seeing 

 my light, they immediately retreated into their holes back- 

 wards. The food, too, was invariably eaten from below, 

 never on the top or edge, the slices of carrot being scooped 

 out on the underside. On several occasions I noticed a 

 dandelion leaf sticking straight up in the pot, having 

 apparently been grasped in the centre and partly dragged 

 into the hole occupied by the larva, just as if it had been 

 bent and forcibly stuck into the ground. I stopped giving 

 them food on April 30, and in looking at the pots on 

 May 25, there were eight larvae on the surface apparently 

 dried up, but on May 31 these eight had turned to pupa." 



Pupa, when but just changed, cream-coloured all over, 

 gradually changing to deep red, the red colour commencing 

 at either end and extending inwards, a white band round the 

 centre remaining visible for some days, so that the last trace 

 of white does not disappear for ten days. In a brittle 

 cocoon of silk and earth underground. (Lieut. Browne.) 



This moth appears never to be captured in the daytime, 

 doubtless it hides among thick herbage in rifts of the rocks. 

 At night it flies freely in its very restricted haunts, and 

 comes readily to sugar if any one is reckless enough to tempt 

 it with that dainty. It also frequents blossoms of ragwort, 

 wood-sage, and other plants ; and is strongly attracted by 

 light, and a constant visitor at lighthouses. Its sole haunts 

 appear to be high sea-cliffs and precipitous rocks. In such
