A Revision of the British Species of Bagous, Schoen. 



By E. A. NEWBEEY. 



The need for a revision of the British species of this genus has 

 long been admitted. I have been induced to attempt the task from 

 having all the British forms in my possession, either in my own 

 collection or lent to me by the kindness of my friends. 



This paper makes no pretension to be a monograph of the genus, 

 since detailed descriptions, both generic and specific, are omitted. In 

 other respects it has been my aim to make it as complete as possible. 

 Those students who require detailed descriptions will find them in our 

 British handbooks and in Brisout's Monof/rcijiJi. The absence of these 

 details has rendered a fuller analytical table necessary, but it is hoped 

 that this will be no disadvantage.
