STIGMONO TIDM -SEMA SIA . 1 6 1 



Larva not certainly described. Mr. A, Thurnall has 

 reared the moth from beech-nuts gathered in September, as 

 well as from spun-up larva on the trunks. 



So far as is yet known, a rare species in this country. 

 It was first obtained here by Lord Walsingham about the 

 year 1868 or 1869 from larvee found by him in cocoons under 

 small patches of moss on the trunks of beech-trees at Little 

 Kimble, Buckinghamshire. More recentlj- Mr. Thurnall has 

 taken the moth on the trunks of beech-trees in Essex. The 

 only other capture here of which I have any knowledge is 

 that by Mr. N. M. Richardson, of a specimen in Hants, in 

 the year 1874. 



By some Continental entomologists it is passed over as a 

 variety of the previous species, and its range abroad does not 

 seem to be noted.
