Exhibitions, Memoirs, &c. 



Mr. F. Bond exhibited specimens o^ Leucania Helmanni, Bdv., 

 and of Nonagria neur:ca, Hiibn., both new to this country, from 

 Yaxley Fen, taken by means of sugar daubed on trees : also 

 specimens of Graph'iphora suhrosea, bred from the caterpillar. 



Messrs. J. F. Stephens and Ingall exhibited specimens of 

 Lachnus quercus, a singular Aphideous insect, new to thi ; country, 

 found in crevices of bark of oak-trees near Dulwich, thrusting its 

 long proboscis nearly up to the base into the wood of the tree, so 

 that it cannot be withdrawn without great difficulty and fear of 

 injuring the insects, in which case the ants immediately rush to 

 suck up the fluids discharged by the Lachnus. 



Mr. Douglas exhibited a new species of CochyUs, also Spilonota 

 foeneUa, Pseudotomia artemisice, Plerophorus calodactylus, &c., 

 from Charlton sand pit. 



Mr. West wood exhibited a new species of Charaxes from India, 

 unique in the collection of Captain Boys, allied to Ch. Eudamippus. 



Mr. Wing exhibited a specimen of the larva of Gortynajlavago, 

 found burrowing into the stems of potatoes. 



Mr. Spence communicated a paragraph from a local newspaper 

 describing the destruction of the foliage of the oaks near Hud- 

 dersfield by the larva of Tortrix viridana, therein described as the 

 Aphis quercus ; affording another instance of the want of a know- 

 ledge of the commonest facts in Zoology among persons whose 

 position in society required their cognizance of such matters, and 

 the consequent necessity of making Zoology a branch of popular 

 education. 



Mr. Edward Doubleday complained of a personal misrepre- 

 sentation which had been made of some of his observations at the 

 last meeting of the Society, concerning the potatoe disease, in the 

 " Illustrated London News."
