 genera which subsequent authors have removed to the Broscinse.

Subfam. AMABINJE. 



A character recently detected by Dr. Horn, viz. the plurisetose and relatively elon- 

 gated penultimate joint of the labial palpi, may be utilized (although its discoverer 





neglected to do so) in separating the genus Amara and its allies from the Pterostichinse, 

 from which the great majority of the Amarce also differ conspicuously in facies and in

group of the genus, also presents the same char 



This group, however, evidently forms the 



between the two subfamilies, the 



number of setse on the joint in question varying in the different species. Some of the

Putzeys, in his 'Etude sur les Amara,' published in the Memoirs of the Royal 

 Academy of Sciences of Liege, the most important work on the group hitherto published, 

 enumerated forty-one species as belonging to this genus, which he considered, like all 

 the other subdivisions of the old genus Amara, a group only, 

 almost exclusively boreal, reaching arctic
