perature of between 6o° and yo° F., with the result that one 

 died, the others revived under the warmth, and in five 

 weeks, six days, one emerged, and the other in six weeks, three 

 days, coming out respectively on the 2nd and 5th of January. 



Mr. Carrington mentioned that he had known two collectors 

 in the north, who were very successful in rearing this insect 

 by artificial means, and used to get all the perfect insects out 

 before Christmas ; and made similar remarks in reference to 

 Deilephila galii, SchirT. 



Mr. South said he had on one occasion obtained a pupa 

 from Dartford, which he left in the sand it had already bur- 

 rowed into in the larval stage, and the perfect insect from which 

 emerged in June of the following year. 



Mr. South exhibited Noctua castanea, Esp., and var. 

 neglecta^ Hiib., and made the following remarks : — 



" This insect is described, as you will know, in Stainton's 

 'Manual,' under Hiibner's name of neglecta, as 'pale grey 

 (with a faint ochreous tinge) or reddish,' and again under the 

 same name in Newman's ' British Moths,' as varying ' from 

 ochreous grey to brick-dust red.' 



" I show this evening examples of the species from the New 

 Forest and two localities in Perthshire. The New Forest 

 specimens are grey, with an ochreous tinge, and are true 

 neglecta. Those from Perthshire, on the other hand, are either 

 grey, with a reddish tinge, or of a decided chesnut colour. The 

 chesnut-coloured specimens are the casta?iea of Esper, and the 

 reddish tinged grey examples connect the two named forms. 



" The species occurs on heaths throughout Central and 

 Western Europe, but is more generally represented by the 

 ochreous grey form, neglecta. Castanea (which, by the way, is 

 Knagg's helvetind) is almost entirely confined to Germany 

 and Britain. 



"The larva, which feeds on heather and bilberry, is some- 

 times brown and sometimes green, but each form is ornamented
