 the life history of Qossus ligniperda.

 disagreeable odour, and he thought that this might partially account for its rapid 

 spread in this country, the odour possibly rendering it distasteful to birds, &c. 



Mr. Dunning made some observations respecting a swarm of Syrphi he had 

 noticed at Walton-on-Naze, in Essex, last autumn. Mr. Verrall had examined some

A discussion then took place respecting the enormous number of Syrphi and 

 Coccinellcs noticed last season, especially with reference to the supposed migratory 

 powers of these latter. The general opinion of the Meeting was, that there was 

 no necessity to suppose immigration to have taken place, as the larvse were most 

 extremely abundant a short time before the appearance of the swarms of the perfect 

 insects.
