366 LEPIDOPTERA. 



anterior feet, and two plates placed transversely upon the 

 upper part of the anterior segments ; the rest of the surface 

 of the body is blackish grey, slightly velvety, and with a 

 light brown dorsal line. It lives in a stout, short ovoid case 

 of a grey-black colour, but which takes the greenish hue of 

 the lichen on which the larva feeds. It eats the lichens 

 growing on old oak fences, on which it passes its life without 

 moving far. In repose its case is held perpendicularly to the 

 plane of its position, and is fixed thus when it arrives at the 

 pupa state. (Bruand.) This description is a little con- 

 tradicted by the author's diagnosis, which reads — "larva pale 

 ochreous, dorsal-plate black " — and there is evidently some 

 confusion here. 



Full fed in June, but doubtless the larva feeds in the 

 autumn, hybernates, and feeds up in the spring on lichens 

 on trees and fences. 



Pupa of the male short and thick, but extremely neat- 

 looking ; rounded in front and on the back, with very long 

 wing and limb cases fitting closely and reaching far down 

 the front of the abdomen, doubtless free at the tips, though 

 this is difficult to see ; abdomen very stout and short, with 

 rows of minute tooth-like points ; anal segment rounded and 

 blunt, but with projecting points at the sides ; uniformly 

 light brown. (I have not seen the pupa of the female.) 

 In the larval case, from the upper end of which the male 

 pupa partly thrusts itself before the emergence of the moth. 



A specimen of the male of this rare species was recorded 

 as having been taken flying round beech trees at Mickleham, 

 Surrey, in the year 1 854. This specimen I have not seen ; its 

 wings are described as long and narrow, and of a pale brown 

 colour. Another is said to have been taken in Epping 

 Forest, among beech. A specimen in my late friend 

 Machin's collection — which he gave to me —and which he 

 reared from a case beaten out of blackthorn at Box Hill, 

 Surrey, and believed to be this species, is F. hctuliiia. Thre^
