Exhibitions, Sfc. 



Mr. Stainton exhibited larrae of a new species of Nepticula,sent from Mentone by 

 Mr. Moggridge, where they were found in the leaves of Euphorbia dendroides. The 

 perfect insect had been obtained from larvae of the previous season, and would be 

 described as Nepticula euphorbiella. 



Mr. Stainton also exhibited the specimen which in 1854 he had described 

 (' Insecta Britannica,' iii. 47) under the name of Nemophora Carteri ; it was 

 formerly in the collection 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 fore 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. Corydon and 

 Alexis, with confluent spots on the under side, and a male-like female of P. Alexis. 



Mr. Druce exhibited a collection of butterflies collected by Mr. Pearson in 

 Bolivia. 



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 Cyuips Kollari. In the 

 spring of 1866 a numerous brood of Clytus arietis appeared in the case ; they were 

 observed running about the oak-stump for about three weeks, when, unable to escape, 

 they died, and their remains were afterwards swept away. The same thing occurred 

 in 1867, and in 1868, on the morning of the Meeting, the Clytus had made its third 

 appearance. The large quantities of camphor placed in the Museum cases did not 

 seem to afifect them, or to prevent the development of the beetle. 



Mr. Janson said that camphor, though useful in preventing the entry of insects, 

 was powerless to destroy them: at the same time he doubted whether the Cl^-tus had 

 been reproduced in the Museum; the insect probably remained in the larva state for 

 two or three years, and it was quite possible that all the larvae from which the 

 successive broods of 1866, 1867 and 1868 had appeared were present in the wood on 

 its admission into the Museum in 1865.
