PI. II, fig. 1. 



A single elytron, indicating a species scarcely smaller than G. nigrita 

 Miill. It is black and of a tolerably dense texture, more than twice as 

 long as broad, with straight and parallel sides, both borders delicately 

 margined, the posterior margin straight on the inner half or more, the 

 inner posterior angle rectangular, the outer well rounded off. The deflexed 

 outer margin is moderately narrow, equal, sculptured like the upper 

 surface, and terminates at the middle of the outer half of the elytron. The 

 surface is irregularly punctate with shallow, moderately abundant, rather 

 minute punctures. The excision of the inner basal angle indicates a rather 

 small equiangular scutellum.

Allied to B. brevidens LeC. A single elytron, about twice as long as 

 broad, the sides almost parallel and straight, slightly broader than else- 

 where just before the tip, the apical marghi straight, not inclined, the 

 outer posterior angle gently rounded, the outer border slightly, the inner 

 scarcely, margined, the deflexed portion of the outer margin narrow, equal, 

 terminating at the middle of the outer half. Texture delicate, the surface 

 slightly, irregularly, and not very closely punctate. A very small and 

 rather broad scutellum is indicated by the shape of the inner basal angle, 

 which is not quite accurately given on the plate. 



Length of elytron, 1-9™"'; breadth, M"™. 



Bledius brevidens is found in New York.
