North American Coleopterous Insects. 189 



Lagria, Fabr- 



To this genus, as it is at present constituted, it seems 

 probable that the following species belong, rather than to 

 Anthicus, under which I published an account of them, 

 stating, at the same time, that they differ much from the 

 other species of the genus that had fallen under my 



observation, viz- : 



Lagria lugubris ; L. coJIdris; L. termindlis ; L- la- 

 hidta; and L. impressa, Nob., but the orbicular tho- 

 rax, the nails being armed with a tooth or abrupt angle 

 beneath, &c. seem to justify, if not the formation of a 

 new genus, certainly ^ division of the present, under the 

 name of Corphyra.
