paler; the pro-thorax is rather shorter. [Included in Le Conte's List as a 

 variety of B. mpestre, Dej., tetracolum, Say, Ent. Works, ii. 503]. 



[54] 78. Peryphus [Bembidium] pictpes, Kirby. — Length of body 2^ 

 lines. Two specimens taken in lat. 65°. 



Body black, glossy, above scarcely at all bronzed. First joint of the 

 antenna rufo-piceous; sculpture of the head, prothorax and elytra precisely 

 that of the preceding species of the genus ; elytra unspotted, with two punc- 

 tiforni impressions situated as in P. scopulinus, &c. ; legs rufo-piceous. This 

 comes very close to P. nitidulus, but that species has no punctiform impres- 

 sions, and the legs are of a different colour. 



79. Peryphus [Bembidium] concolor, Kirby. — Length of body 2 \ lines. 

 Body and members black, glossy, above bronzed. Scape of the antennae 



piceous; prothorax less constricted behind than in P. picipes; space between 

 the basilar impressions impunctured; elytra more deeply furrowed with larger 

 punctures in the furrows ; the lateral furrows are not obliterated, but the 

 apex of the elytrum is impunctured. [A species unknown to Le Conte.] 



80. Perypus [Bembidium] quadrimaculatus, Linn. — Two specimens 

 in lat. 54°. [Subsequently described as B. opposilum^ Say. — Ent. Works, 

 ii. 501 ; taken in Canada.] 



[55] 81. Peryphus [Bembidium] nitidus, Kirby. — Plate i. fig. 7. 

 Length of body 3| lines. Two specimens, taken lat. 54°. 



Body linear-oblong, subdepressed, very glossy, underneath black, above 

 black-bronzed. Head triangular; frontal impressions long and rather curvi- 

 linear; scape of the antennae rufous underneath; prothorax nearly square, 

 and level with curving sides ; dorsal channel nearly obsolete ; basilar impres- 

 sions double, the inner one round and rather deep, the other very slight, with 

 a little ridge between it and the margin ; anterior and posterior margin nearly 

 straight ; elytra with sides nearly parallel as well as the apex impunctured ; 

 a quintuple series of punctures adjoins the suture, which extends very little 

 beyond the half of the elytrum, with traces of' slight furrows beyond it. 

 [Taken in Canada ; a specimen in our collection from Mr. B. Billings, Ottawa, 

 Ontario; at Fort Simpson, Mackenzie River, by Mr. Kennicott; and in the 

 Platte River Valley, by Dr. Le Conte]. 



[56] 82. Tachyta picipes, Kirbij. — Plate viii. fig. 6. Length of body 

 1^ lines. Four specimens, taken in lat. 54°. 



Body black, glossy. Frontal impressions rather oblique; eyes less promi- 

 nent than usual in the tribe; prothorax broader than long, subobcordate ; 

 basilar impressions, which are single, and dorsal channel, rather deep; elytra 

 with three obsolete impunctured furrows next the suture, which do not reach 

 the apex. Apex rounded ; legs piceous. [Previously described as TacJiys
