The Author. Parts I. and II. of a Memoir on the Tem- 

 perature of Insects, by George Newport. 



The Rev. F. W. Hope exhibited five cases, being part of a 

 very fine and extensive collection of insects, principally from 

 Mysore and Ceylon. 



Mr. Hanson exhibited three boxes filled with insects, prin- 

 cipally Coleoptera and Lepidoptera, being part of the collec- 

 tion now making in North America, by their Corresponding 

 Members, Messrs. Doubleday and Foster, for the Entomo- 

 logical Club. 



Mr. Westwood exhibited a sample of Cayenne Pepper, 

 attacked by Annohia ; also a small portion of peat, to which 

 were attached particles of what appeared to be the elytra of 

 insects, obtained from a depth of about fifty feet, near the 

 foundation of one of the bridges in Bristol ; both communicated 

 by Mr. Raddon. 



Mr. Spence made a communication on the vast numbers of 

 the wire-worms, and o{ Agnotis segetum, that had been destroyed 

 from a field of turnips by the hand-picking of children, and 

 thus a valuable crop saved at a trifling expense. 



Mr. Shipster exhibited a nest of the " trap-door" spider, 

 received from South Australia, in which the door was of a 

 semi-circular form, and so nicely constructed, that the roots of 

 grass were still undisturbed in the lid. 



Mr. Westwood read a paper, by himself, on the produc- 

 tion and natural history of Hybrids, in reference more parti- 

 cularly to those specimens reared by Mr. House, and exhibited 

 at the November Meeting, accompanied by a drawing illus- 

 trative of both upper and under sides. A detailed account of 

 all the most remarkable instances of these occurrences was 

 contained in the paper; and the argument respecting the proper 

 identity of species, or their intermixture, by which possible new 

 ones might be indefinitely created, was gone into at length by 

 the author. His conclusion was in favour of the true isolation 

 of species, which view was strongly supported both by the Rev.
