Our illustrious countryman, the late Sir Humphry Davy, 

 instituted a prize for the encouragement of the physical and 

 natural sciences at Geneva ; this prize is allotted to the work 

 before us, which has our unqualified approbation. It contains 

 a history of all preceding works on this tribe ; also, figures and 

 descriptions of their external and internal anatomy, and of the 

 species, with many of their larvae and pupae, &c, found in the 

 basin of Geneva.
