Hufn., one bred from larvae fed on elm, and the other on sallow. He 

 stated that those fed on elm were, by accident, kept without food for some 

 time after the first moult, and in consequence most of the brood perished. 

 Nineteen reached the perfect stage, of which only two were females. Mr. E. 

 Joy, bred examples and pupse of Plusiafe&tuca, L. Mr. Tugwell, a box 

 of Lepidoptera, collected by Mr. Lachlan Gibb in Canada. Mr. R. Adkin, 

 specimens of Tortrix piceana, L., from Surrey and Hampshire, and 

 expressed an opinion that the species was more widely distributed than was 

 generally supposed. Mr. South remarked that the species had been 

 known in England for many years. Mr. Fenn thought it had been over- 

 looked owing to the difficulty in obtaining the larvse, which fed on the tops 

 of the trees. Mr. C. G. Barrett said the species was an abundant one on 

 the Continent. Mr. Hawes, examples of Argynnis euphrosyne, L., 

 showing considerable variation in the black markings. Mr. P. Bright, two 

 varieties of Arctia caia, L., one very dark and the other an extremely pale 

 form ; also a series of Triphcena orbona, Hufn. (subsequa, Hb.), from Forres. 

 Mr. Bright stated he had written for further particulars of the specimen of 

 Vanessa exhibited by him on the 25th ultimo, and which was stated to 

 have been taken at Polegate ; he understood that Mr. Weir, referring to 

 this specimen, had expressed an opinion that it was an example of Vanessa 

 milberti. Mr. Cockerell exhibited a cocoon of Zygana filipendulce, L., 

 from near Leigh, Essex, not uniformly yellow, remarking that sometimes 

 the cocoons of this species were half yellow and half white or whitish. He 

 also showed Myzius sexcincta, Fabr., from Long Island, and said that this 

 species was found by Dr. Riley in the stomachs of sparrows (Passer 

 domesticus) in thirty instances, thus showing that its wasp-like attributes 

 did not protect it from that bird ; also a Tipulid fly allied to Tipula, but 

 apparently belonging to a new or little-known genus from Swift Creek, 

 Custer Co., Colorado, where it mimics a species of Ichneumonidse found in 

 the same locality. 



November 13th. — W. H. Tugwell in the chair. Messrs. G. Champion, 

 of St. John's Wood ; A. J. Hodges, of Highbury ; and A. H. Hill, of 

 Hampstead, were elected members. Mr. Wellman exhibited Bryophila 

 impar, Warren, from Cambridge, and a specimen of B. muralis, Forst., 

 from Folkestone, very similar to the examples of impar. Mr. Tugwell, 

 long series of Cerastis vaccinii, L., and of G. spadicea, Hb. A discussion 

 ensued as to this exhibit, in the course of which Mr. South said that spa- 

 dicea, Hb., was a form of vaccinii, and that the form shown by Mr. Tugwell 

 as spadicea was known on the Continent as subspadicea, which was said to 

 be a form of C. ligula, Esp. Mr. C. G. Barrett remarked he had never 

 had any difficulty in separating the two species. Mr. R. Adkin, examples 

 of Spilosoma mendica, Clerck, bred from ova obtained by the pairing of a 

 female of the Irish form of the species with a male of the English form. 

 From the ova obtained only two moths were bred, both of which were 

 males, and neither were like the English or Irish form. Mr. Tugwell re- 

 marked that Mr. Adkin having bred the species from the two forms, there 

 could be no longer any doubt as to the two forms being one and the same 

 species; the two examples shown were very similar to the Yorkshire 

 specimens bred by Mr. Harrison. Mr. Adkin also exhibited Peronea 

 sponsana, Fb., from the New Forest, and referred to his exhibit of this 

 species in 1889, when nearly all those then shown were the variety. This 

 year he had endeavoured to obtain the species as it occurred in the New
