[50] 82. Taciiyta picipes, A7%.— Plate viii. fig. 6. Length of body 

 1^ lines. Four specimens, taken in lat. 51°. 



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

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

 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 Tachys 

 nanus, Schaum, and Bemb. inornalum, Say. — Ent. Works, ii. 502 ; taken in 

 Canada.] 



[57] 83. NoTAPiius [Bembidium] nigripes, Kirly. — Length of body 

 2 lines. Three specimens, taken in lat. 54°. 



Body black, glossy; above bronzed with a greenish tint; the whole upper 

 surface, under a powerful nangnifier, appears covered with innumerable 

 granules, which are much more distinctly seen in this family than in the 

 FerypJiidcc. Scape of the antenna), which are longer than the prothorax, 

 rafo-piceous; frontal impressions parallel; the punctiform impression adjoin- 

 ing the eyes on their inner side has a central elevation : prothorax short, with 

 a deep dorsal channel ; basilar impressions double, with a little ridge between 

 the external one and the margin: elytra furrowed; furrows punctured for 

 about two-thirds of their length ; the first and second reach the apex, where 

 they are confluent; the third and fourth stop a littb short of the apex, and 

 are also confluent, as are the fifth and sixth, which are still shorter, and 

 terminate in a little furrow common to both ; the seventh and eighth reach 

 the apex, where they likewise unite; two punctiform impressions, in the 

 usual situation, adjoin the third furrow ; at the base of the elytrum, in the 

 interstice between the fifth and sixth furrows, is a longitudinal lurid streak, 

 then follows an abbreviated and articulate band of the same colour, consisting 

 of four streaks, those near the lateral margin being much the longest; in the 

 interstices between the second and third furrows are two such little streaks ; 

 near the apex is likewise another band, both articulated and undulated, con- 

 sisting of seven spots, the marginal one being rather the longest ; the tips of 

 the elytra are likewise lurid. 



N. nvjripes is related to N. usUdatus, and appears to be its American 

 representative ; it differs from it in having black legs, and the lurid markings 

 of the elytra are different : it comes nearest to Gyllenhal's Variety C. [ Vide
