Note.

Nebria macrocephala Motschulsky was described from specimens originating "probablement de Sitka ou d’Ounalachka [Alaska]" (Motschulsky 1844: 128). The name is listed as a junior synonym of Nebria gregaria Fischer von Waldheim, 1820 in Ledoux and Roux (2005: 222) but according to Bänninger (1923: 131) only the specimens reported subsequently by Motschulsky (1860: 97; 1866: 273) as Nebria macrocephala belong to Nebria gregaria . The syntypes are conspecific with specimens of Nebria stigmula Dejean, 1826 (= Nebria hellwigii Panzer, 1803) as noted by Mannerheim (1853: 111). The provenance given by Motschulsky is probably incorrect.
