Dec -> J 9i9-] Notman : Bembidium. 293 



In the Fauna Boreali Americana (Vol. IV, p. 57) Kirby described 

 a Bembidium (Notaplms) nigripes. This species seems satisfactorily 

 identified as a small black-legged form allied to B, patruele and B. 

 posticum. A large series was collected at Cochrane where it is 

 abundant. Mannerheim later described a different species, taking it 

 for Kirby's (Bull. Mosc, No. 2, 1852, p. 300). Leconte discovered 

 this error and named the species described by Mannerheim, B. incre- 

 matum (Proc. Acad. Nat. Sci. Phila., i860, p. 316). He says: "The 

 Russian American (species) described as B. nigripes (Kirby) by Man- 

 nerheim, is totally different, being much larger, with the pale bands 

 of the elytra very badly defined and the epipleurae pale, resembling 

 (in) these characters B. indistiiictum Dej. from California; it differs, 

 however, from that species by the thorax being more strongly mar- 

 gined, with the posterior angles more rectangular and prominent, and 

 the basal carinae very distinct ; the dorsal line and impressions are 

 likewise deeper. In all these respects it agrees with B. approximation 

 Lee, but differs by the punctures of the elytral striae being larger and 

 less closely placed. The femora are dark : in B. approximatum the 

 legs are usually pale, though sometimes dark, in B. indistinctum they 

 are always pale. The species will hereafter be known as B. incre- 

 matum; it differs from all the allied species by the seventh elytral 

 stria being obliterated and represented only by punctures." 



In the Coleoptera of Michigan (Proc. Amer. Phil. Soc, XVII, p. 

 594) Leconte described B. arcnatum. He says : " Prothorax wider 

 than long, rounded on the sides, strongly sinuate behind, base as wide 

 as the apex; hind angles rectangular, carinate; basal impressions 

 deep, dorsal line well-impressed, transverse impressions feeble. 

 Elytra elongate-oval." Then following the description : " Marquette, 

 Lake Superior. This species resembles B. flammnlatum (denteUum) 

 of Europe, but is wider and less convex. It also greatly resembles 

 B. incrematnm Lee. from Cal., Oregon and Alaska, but the latter has 

 the elytral markings undefined, and the striae finer and less strongly 

 punctured." 



Hay ward in his paper on the genus (Trans. Am. Ent. Soc, IX, 

 P- 97) gives descriptions of two species: B. graciliforme, described as 

 new, and B. dentellum Thunb. The latter he states to be identical 

 with incrematnm Lee. and arcuatum Lee. Hayward's two species are 

 easily recognized in a series of 79 specimens collected by the writer
