larvae which grew in all sorts of wild places, grassy spots 

 among stones in lanes, and were practically never eaten down 

 at all ; and bearing this in mind, the cause suggested by 

 Mr. McRae would not account for the total disappearance of 

 C. edusa. Mr. Weir asked whether he understood Mr. Tutt 

 to say that C. edusa never hybernated in this country, and in 

 reply Mr, Tutt said there were one or two records of it 

 having been taken early in the year, but they were solitary 

 examples. 



OCTOBER 27th, 1892. 



C. G. Barrett, Esq., F.E.S., President, in the Chair. 



Mr. Hugh Main was elected a member. 



Mr. Briitowe exhibited Zygcsna trifolii, Esp., intermediate 

 between the normal form and the yellow variety ; also a variety 

 of Argynnis papJiia, L., taken at Brockenhurst, Hants, in which 

 the spots had coalesced and formed streaks. 



Mr. R. Adkin exhibited Odoiiestis potaioria, L., bred from 

 larvae collected in Sussex, the series showed considerable 

 variation, and he also called attention to the wings of some 

 of the females being much scalloped, but still retaining com- 

 plete fringes. Other instances of like malformations were 

 referred to by several members. 



Mr. C. Fenn exhibited Tortrix rosana, L., from Aberdeen 

 and Eltham, and remarked that there was some doubt as to 

 the examples from Aberdeen being referable to this species, 

 but Mr. Barrett was of opinion that they were correctly 

 named. 



Mr. C. G. Barrett exhibited two specimens of Nonagria 

 concolor, Gn., one taken in the Yaxley Fen district thirty or 

 forty years ago, the other recently captured in a locality in 

 the Midland Fen district, and forwarded by Dr. T. D. Wheeler. 

 Witii these for comparison, specimens of A^. hellmanni, Evers., 

 N.fulva, Hb., N. bondii, Knaggs., and Miana arawsa, Haw., 

 showing the specimens in those species which approach closely 

 to N. concolor in colour. 



Mr. Tugwell stated that this year he had reared some eight 

 or nine examples of the Vd,\s\ey Enpithecia, and which he be- 

 lieved to be a form of E. castigata, Hb., from larvae fed on 

 heather, both the leaf and the flower being eaten ; all the 

 specimens were certainly black, but some were darker than 

 others, and the whole of them had comparatively little mark- 

 ing. He understood from his Paisley correspondents, however, 

 that these dark pugs were invariably found on pine trunks 

 (see also ante, p. 21).
