THE SOUTH LONDON ENTOMOLOGICAL AND NATURAL 



HISTORY SOCIETY. 



September 22nd, 1892. — C, G. Barrett, Esq., F.E.S., President in the chair. Mr. 

 R. Adkin exhibited Oxyptilus distans Zell., and 0. pilosellce, Zell., taken near Dover 

 this summer, and also on behalf of Mrs. Hutchinson, of Leom.inster a small collection 

 of Micro lepidoptera from Cornwall, including Diascmia literuta, and a remarkably 

 brightl}' marked small form of Herlnda cespi talis, said to be exceedingly local. Mr. 

 South a voriable series of Grapholitlia ciiieraiia, taken on the borders of Middlesex, 

 between Northwood and Richmansworth. He stated the species was abundant on 

 the trunks of two grey poplars (Popnlas canescens) at the end of July and beginning 

 of August, also G. nesella and the varieties paronana, Don., boeborana, Fab., and rhom- 

 bifasciaiia, Haw., and remarked that although some specimens of the latter species 

 varied in the direction of G. cinerana, they could always be distinguished by the 

 different shape of the outer edge of the basal patch. Two examples of /'^;^ra;zir, Hh.=as- 

 pidana, Haw., a form wliich was generally considered to be a variety of G. nisella, were 

 found with G. cinerana. As the basal patch agreed with that of G. cinerana, he was 

 inclined to think that petrana was a form of G. cinerana, rather than of G. nisella. 

 Mr. Fenn stated that both species of Grapholitha were abundant on poplar in Kent. 

 Mr. Barrett observed that he had always understood that G. nisella was associated 

 with sullow, and that its occurrence on poplar was new to him. Mr. Mc Arthur 

 showed the life history of Sesia scolii/onnis, Bork., from Rannock, also Hepialns kumiili 

 L., from the Shetlands with the var hethlandiea, Stgr., Mr. Frohawk and Mr. 

 Carpenter exhibited Vanessa atalanta, L. Mr. Frohawk referred to the small white 

 spot on the red band which was generally thought to indicate the female, but he 

 showed females with and without the white spot, and one male which also had this 

 and other female characters. Mr. Carpenter made sorne observations upon the abun- 

 dance of the larva of Vanessa atalanta on Streatham Common, and remarked upon 

 the variation in size, some were full fed whilst others were quite small. A discussion 

 then ensued as to the double broodedness of this species, in which 'vlessrs. Carpenter, 

 Tutt, Fenn, Barrett, Carrington and Frohawk took part. — H. \V. Barker and A. 

 Short, Hon. Sees. 



October lyh, 1892. — The I^resident in the chair. Mr. James, of Uphill, Folkestone 

 was elected a member, Mr. Adye on behalf of Mr. \V. MacRae exhibited large 

 numbers of Colias liyale, L., C. ediisa, Fb., and var helica, Hb., a part of the result of 

 five days collecting in the neighbourhood of Bournemouth and Christchurch, and 

 Mr. Adye read some notes as to the proportions in which helice and hyale occurred as 

 compared with edusa, he also expressed an opinion that the explanation of editsa not 

 occurring two years in succession was principally due to the ova, which he stated 

 v.'ere always laid on the upper surface of clover blades, being destroyed by the 

 grazing of sheep and cattle and the action of mowing machinery. A discussion 

 followed, and the members taking part therein were of opinion that this explanation 

 was entirely inadequate. Mr. Adye also exhibited living larva and pupse of C. edusa 

 and two specimens of 7_)L'?V;/'6'm />;j/r/.';\7t/ L., from Christchurch. 3/Ir. Henderson also 

 showed a specimen of this species taken by him at Hayling Island. Mr. Dennis a 

 variety of the underside of Lycuna adonis., the ground colour being white, and only
