Bembidium glaciatum. 

 PI. 1, Fig. 40. 



A couple of elytra represent this species, which seems to be nearly 

 allied to the scarcely smaller B. longulum LeC. The humeral angle is not 

 quite so prominent, and the stria; and punctures are more heavily marked. 

 The striae are indeed rather deeply impressed and equally so over the whole 

 width of the elytron, but all become less pronounced and even obsolescent 

 apically ; the same is true of the punctures which on the basal half of the 

 elytra are very heavy, making transverse creases in the neighboring inter- 

 spaces, so that they are rather transverse than longitudinal or even circular. 

 The sutural stria is as in B. longulum, and the texture of the surface of the 

 interspaces, instead of being as in the modern species almost structureless, 

 is marked with a fine but decided cross-ribbing, verging upon reticulation. 

 The color is a rich carbonaceous with a purplish tinge.

Bembidium fragmentum. 



PI. 1, Fig. 45. 



Another species of Bembidium from the glacial clays is represented by 

 a single elytron with the tip broken off, differing from the preceding by its 

 much less heavy markings and agreeing better among modern types with 

 B. constrJctum Say, which is of about the same size. The elytron is black, 

 with a remarkably little developed humeral angle (though this is exagger-
