THE ENTOMOLOGIST. 



No. 51.] MARCH, MDCCCLXVIII. [Price 6d.. 



Proceedings of the Entomological Society of London. 



January 28, 1868. — Anniversary Meeting. — Sir John 

 Lubbock, Bart., President, in the chair. 



The Secretary read the Report of Council and Auditors, 

 after which 



The President delivered an Address on the Entomological 

 Literature of Europe during the past year, observing that the

 referring especially to the observations of Aristotle, and then 

 describes successively the mechanism by means of which 

 sound is produced among the Orthoptera, Coleoptera, 

 Diptera, Homoptera, Lepidoptera, Hymenoptera and Neu- 

 roptera. The number of insects which emit audible sounds 

 is very large, and there can be no doubt that many more pro- 

 duce tones which, though inaudible to us, are perceptible to 

 one another. This is shown by the fact that many species 

 which are apparently silent possess arrangements evidently
