Mr. Hardy has communicated a paper on New British Homoptera 

 to the ' Transactions of the Tyneside Naturalists' Field Club;' and a 

 second paper by the same author, " On an Acarus which attacks 

 Grapes," was read at the Meeting of the British Association, and pub- 

 lished in the 'North British Agriculturist,' vol. ii. No. 34, Aug. 1850. 



Mr. Westwood's continuation of ' Doubleday and Hewitson's 

 Genera of Diurnal Lepidoptera ' maybe here noticed ; and the follow-

 Turionana ; together with articles on Rose-tree Insects, and other

To the labours of our continental brothers in Entomological Sci- 

 ence, I feel that I cannot do full justice, since several periodicals, 

 Proceedings of Societies, &c, which usually contain Entomological 

 papers, I have been unable to consult. The subjoined list of contri-

' Annales de la Societe Entomologique de France? for 1850, in
