the very apex, the third interval as wide as the others, and with two 

 small dorsal punctures, one a little behind the middle, the other about 

 one-fourth from apex, neither shown in the drawing. It seems to be 

 most nearly allied to B. sculpturatum Motsch., but is a little smaller and 

 slenderer, the striae a little less impressed, the puncta more delicate, and 

 the intervals a little less convex. It measures 4°"° in length by 1 ■"" in 

 breadth. 



One specimen : No. 16794, Logan's brickyard, Toronto. 

 B. sculpturatum was described from Alaska, and according to Hay ward, 

 occurs also in California. 



The species is named for Mr. Roland Hayward, whose careful revision 

 of the American species of Bembidium has been of much service in the 

 study of these fossils. 



Bembidium vestigium sp. nov. 

 PI. VI., Fig 4. 



Represented by the larger and proximal part of an elytron, piceous, 

 with subangulate humerus, well impressed and rather delicately punctate 

 striae and flattened intervals, the third interval of a similar width to the 

 others and showing a single dorsal puncture, not given in the drawing, 

 just before the fracture, or probably distinctly beyond the middle of the 

 elytron. It appears to be most nearly allied to B. rohuslicolle Hayw., 

 the flatness of the intervals, the impression of the strise and their punctu- 

 ation being very much as in that species, besides being of about the same 

 size; but the first dorsal puncture lies further back, and the first three 

 strise are more deeply impressed than the others, while all are alike in the 

 existing species. The length of the fragment is 3-2 "", and the probable 

 length of the elytron 5 "^ ; its breadth 1 -5 °"°. 



One specimen : No. 16808, Scarborough. 



B. robusticolle is reported from Michigan, Iowa and Kansas. 



Bembidium vanum sp. nov. 



PI. VI., Fig. 5. 



Represented by two elytra, neither quite perfect, one lacking the distal 

 fourth, the other being a little broken both at base and apex ; apparently 

 with the two preceding belonging to one group. The humerus is hardly 

 subangulate but strongly rounded, the strise not very deeply impressed, 

 but somewhat heavily punctate, the intervals nearly flat ; the third 

 interval is of similar width to the others and shows the first dorsal
