24 (23) Pronotum subtrapezoidal; lateral margins convex, rectilinear or slightly sinuate before posterior angles. Basal impressions of pronotum indistinctly punctuated subgenus: Actephilus Stephens, 1833 25 (16) Metafemora with very irregular (apparently more than one) rows of setigerous punctures (and longer setae): number of punctures (and longer setae), as a rule, more than 10. Ventral pubescence (disregarding obligate, exserted, longer tentorial setae) distinct, consisting of silky or rougher, relatively long hairs. 26 (27) Ventral side of protibiae (at apical half) with two rows of short bristles. A short row (usually 3-5 bristles) present on exterior apical margin of tibia; interior row long (consisting of numerous bristles), running about parallel with exterior margin of tibia, not reaching apex subgenus: Hypsinephus Bates, 1878 27 (26) Ventral side of protibiae (at apical half) with one row of numerous short bristles. At first this row running about parallel with exterior margin of tibia, then running obliquely right to exterior apical margin. 28 (29) Pronotum subcordiform: lateral margins distinctly sinuate before posterior angles. Punctuation of basal impressions of pronotum extending to a great part of pronotal base, and (as a rule) extending as far as lateral margins subgenus: Acardystus Reitter, 1908 29 (28) Pronotum subtrapezoidal: lateral margins convex or rectilinear before posterior angles. Punctuation of basal impressions of pronotum obsolete and indistinct, extending to, at most, a small part of pronotal base, besides a few obsolete punctures may be present near posterior angles and lateral margins subgenus: Haploharpalus Schauberger, 1926 30 (15) Head relatively large; neck relatively broad. Eyes relatively small and slightly protruding. Anterior region of prosternum with long, fine hairs genus: Pangus Dejean, 1821 Many writers have dated the genus Masoreus from 1828, under the belief that it was based previously on an undescribed species. This genus was established by Dejean (1821) with one species ^Luxatus. Creutz."). This is Harpalus luxatus described by Audinet-Serville (1821). As Audinet-Serville's work (issued in March) antedates that of Dejean (issued in May), therefore, the generic name Masoreus is available since 1821. It has generally been supposed that the type species of the genus Lebia Latreille, 1802 is Carabus cruxminor Linnaeus, 1758. The type is, however, Carabus quadrimaculatus Linnaeus, 1758 (fixed by Latreille, 1810, by subsequent designation), and the generic name Lebia is a senior objective synonym of Dromiasa Hoffmann, 1834 (Dromius of authors, not Panzer, 1813). (Dromius Panzer, 1813 is a junior primary homonym of Dromius Borkhausen, 1797 and a senior objective synonym of Syntomus Hope, 1838.) The oldest available name for the genus erroneously called as Lebia is Lamprias Panzer, 1813 (type species: Carabus cyanocephalus Linnaeus, 1758, fixed by Panzer, 1813, by monotypy). The subgenus represented by Carabus cruxminor and its congeners should now be nominated as Callilebia Crotch, 1870 (type species: Carabus cruxminor Linnaeus, 1758; fixed by Crotch, 1870, by monotypy). Most writers have dated the genus Plochionus from 1825, under the belief that it was previously connected with unavailable specific names. This genus was established by
