Darwin was also desirous of acquiring facts bearing on the 

 distinction between sexual and protective colouring in insects; 

 and of ascertaining the causes which decided the success of 

 one out of several males which were in pursuit of the same 

 female. 



March 16, 1868. — H.W.Bates, Esq., President, in the chair. 



Mr. Charles Carrington, of Westwood Park, Forest Hill, 

 was elected a Member. 



Mr. Stain ton directed attention to the account given by Herr 

 Hartmann, in Stett. Ent. Zeit. 1868, p. 109, of the breeding of 

 Sesia cephiformis, Grapholitha duplicana, .Z'e/^. (interruptana, 

 H.-S), and Gelechia electella, from gall-like swellings on 

 the twigs of juniper bushes : an examination of the juniper 

 during the spring would probably lead to the discovery in 

 this country of the larvae of the two last-mentioned species. 



April 6, 1868. — H. W. Bates, Esq., President, in the chair. 



Mr. Stainton exhibited the specimen which in 1854 

 he had described {' Insecta Britannica,' iii. 47) under the 

 name of Nemophora Carter! ; it was formerly in the collec- 

 tion of the late Mr. S. Carter, of Manchester (who, however, 

 was unable to give any account of the insect or its place of 

 capture), and had now passed into the possession of Mr. S. 

 Stevens. Recent examination had convinced Mr. Stainton, 

 and the exhibition of the specimen satisfied the other 

 Lepidopterists present, that the supposed Nemophora Carteri 

 was a fabrication, made by attaching the hind wings of a 

 Cerostoma to the lore wings of a Nemophora. 



Mr. W. C. Boyd exhibited a strongly marked variety of 

 Stenopteryx hybridalis, captured in Hertfordshire. 



Mr. J. Jenner Weir exhibited a Polyommatus captured at 

 Lewes, which he regarded as a hybrid between P. Adonis and 

 Alexis; also varieties of P. Cory don and Alexis, with con- 

 fluent spots on the under side, and a male-like female of 

 P. Alexis. 



Mr. F. Smith mentioned that about September, 1866, Mr. 

 Waring Kidd had sent to the British Museum a pollard oak, 

 which was placed in a closed case in one of the galleries, for 

 the purpose of showing the modus operandi of Cynips Kollari. 

 In the spring of 1866 a numerous brood of Clytus Arietis
