Note on the Larvce of Plutella porrectella. — As a contribution to the second edition 

 of Mr. Stainton's ' Entomologist's Companion,' I beg to state that in the second week 

 of February, 1852, I observed in my own garden the tops of the double white rocket 

 agglutinated, and on examination they were found to contain active larvae of Plutella 

 porrectella. I believe there are three broods in the course of the year, as I last season 

 observed the perfect insect early in spring, again in June, and late in the autumu. 

 The ravages of this little pest are truly provoking to the florist, as it requires the great- 

 est watchfulness to prevent the heart of this handsome plant from being destroyed. —

Proceedings of the Linnean Society. 



February 17, 1852. — Robert Beown, Esq., President, in the chair. 



The receipt of a complete series of the publications of the Palaeontographical So- 

 ciety, presented by that Society, was announced. 



Read, the continuation of Mr. Joseph Woods' 'Notes of a Botanical Tour in France.' 



Mr. Curtis called the attention of the meeting to the fact of a cavity being formed 

 anmod Soldaiiella alpina, when flowering beneath the snow, as recorded by Dr. Lortet 

 in the ' Annals of the Agricultural Society of Lyons.' This phenomenon was referred 

 by M. Lortet to the development of heat by the plant. 



Dr. Lankester suggested that it might perhaps be owing to the absorption of heat 

 i>\ the (lark parts of the plant.
