larger head, and especially by the acute rather than obtuse 
basal angles of the prothorax. Appalachia is one of our 
smallest, perhaps really our smallest, Nebria, and is appar- 
ently a strictly alticoline species. Careful search at 3,500 
feet along the banks of the very stream, on the upper 
reaches of which the type series (Smoky Mountains) was 
collected, did not yield a single specimen. 
Pterostichus (Gastrellarius) unicarum n. sp. 
Small, slender, but slightly ventricose; dark brown or 
piceous, antennae, palpi, tarsi, and apices of tibiae rufous. 
Head with two setigerous punctures over each eye; eyes 
moderately prominent ; antennae long and slender ; mentum 
tooth entire, elongate, triangular, bluntly pointed at apex. 
Prothorax by actual measurement very slightly wider 
than long; lYg times as wide as head; somewhat con- 
stricted toward base; base slightly narrower than apex, 
% as wide as widest part; sides evenly arcuate in anterior 
%, rather strongly sinuate before the rectangular basal 
angles; lateral margin very fine and even; base margined, 
but sometimes indistinctly so at middle. Pronotum with 
basal and apical transverse impressions faint, connected 
by a deeper, longitudinal impressed line on middle of disc; 
later basal fovese linear, extending from base Yg or less 
toward apex; surface of pronotum impunctate even about 
the fovese. 
Elytra more than *4 wider than the prothorax % to % 
longer than wide; striae entire, not or just detectibly punc- 
tate; 3rd interval with a single setigerous puncture at or 
just behind the middle. Inner wings atrophied. 
Anterior tarsi of $ slightly dilated, first 3 joints pubes- 
cent below; apex of last ventral segment with 1 bristle on 
each side in $ , 2 in $ . 
Length 6. 2-7. 5 mm. Width 2.5-3 mm. 
All specimens from the Smoky Mountains, as follows: 
Holotype $ , allotype ? , and 33 paratypes from New- 
found Gap, North Carolina-Tennessee state line, 5,000-5,200 
feet. 4 paratypes from State Road to Newfound Gap, Ten-
