slightly punctured, at the apex impunctured. [Placed in LeConte's List, 

 p. 10, with a mark of interrogation, under Amara septentrionalis, Lee, and 

 with the note that the name has been previously employed for another 

 species.] 



[51] 73. Patrobus Americanus, Be Jean. — Three specimens taken in 

 Lat. 54°. Length of body 5f lines. 



[Previously described as Feronia {Patrobus) longicollis, Say. ; not un- 

 common in Ontario. For description vide Say's Ent. Works, ii. 466.] 



[52] 74. Peryphus [Bembidium] bimactjlatus, Kirby. — Length of 

 body 3 J lines. Taken in lat. 65°. 



Body glossy, underneath black, above black-bronzed with a slight greenish 

 tint. Head triangular, with a thick convex neck- frontal impressions long 

 and deep; antennae longer than the prothorax, third joint of the length of 

 the succeeding ones ; scape and palpi rufous ; prothorax obcordate convex, at 

 the base depressed, constricted and grossly punctured ; dorsal channel as in 

 Patrobus; basilar impressions single, round and deepish; elytra slightly fur- 

 rowed, with the furrows punctured; the seventh from the suture nearly obli- 

 terated; apex nearly smooth, near which is an oblique pale spot ; legs rufous 

 with darker thighs, especially in the middle. 



N. B. — When the elytra are raised from the body, they are dusky-bronzed. 

 [The old genus Peryphus is included by Le Conte as a group under Bembi- 

 dium, Pro. Acad. N. S. Phil. 1857, p. 3.] 



75. Peryphus [Bembidium] sordidus, Kirby. — Length of body 3 lines. 

 A single specimen taken in lat. 54°. 



This so nearly resembles P. bimaculatus, that I first put it aside as an 

 immature specimen, but further consideration induces me to consider it as 

 distinct. It is wholly pale rufous, except the head, the prothorax and the 

 anus : the three first joints of the antennae and the base of the fourth are 

 also rufous : the prothorax appears rather narrower in proportion, and less 

 distinctly punctured at the base ; the spot at the apex of the elytra is larger, 

 and the thighs are rather slenderer. 



[53] 76. Peryphus [Bembidium] scopulinus, Kirby. — Two specimens, 

 taken in lat. 54°. [Previously described as B. postremum, Say, Ent. Works, 

 ii. 561]. 



77. Peryphus [Bembidium] rupicola, Kirby. — Taken abundantly in 

 lat. 54° and 65°. Length of body 2| lines. 



This little species appears to be the American representative of P. littoralis } 

 which in many respects it closely resembles. It is, however, a smaller insect. 

 The body is invariably piceous or rufo-piceous, and the head and prothorax 

 are of the same colour, bronzed; the antennae are ferruginous, with the scape
