1931] Carabidse from North Carolina and Tennessee 159 
Since all our species are mutually similar in appearance 
and in most points of structure, the following brief descrip- 
tions are all that are necessary to characterize them. I 
shall take the commonest and best known species, diligendus 
Chd. ( osculans Csy.) , as a basis for comparison of the 
others. All of the species are found under stones and logs 
in damp forests. 
1. Pterostichus (Monoferonia) primus n. sp. 
Of usual form and appearance for the subgenus ; sides of 
prothorax oblique and usually slightly sinuate before the 
basal angles; latter only minutely rounded at apex, and 
therefore more abrupt than in diligendus; outer basal stria 
of pronotum nearly or quite obliterated ; elytral striae com- 
paratively little impressed, distinctly punctulate in basal 
intervals slightly convex anteriorly, completely flat in 
posterior ; last ventral of $ slightly impressed behind 
the middle, with a very weak transverse ridge adjacent 
to the apical margin. 
Length 10.0-11.3 mm. Width 3. 6-4.0 mm. 
Smoky Mountains at comparatively low elevations: 
holotype $ , and 2 ( $ 9 ) paratypes from Deep Creek 
(Bryson City), N. C., near 2,000 feet; 2 ( <2 9 ) paratypes 
from State Road to Newfound Gap, Tennessee side, 3,500 
feet. All collected by myself. A pair of paratypes is in 
my own collection; the rest of the type series, in the Mu- 
seum of Comparative Zoology (No. 16435). 
2. Pterostichus (Monoferonia) diligendus Chd. 
(1868, p. 334) 
osculans Csy. (1884, p. 2) 
apalachius Horn (1892, p. 41) 
appalachius (as corrected by) Csy. (1913, p. 132) 
Of usual form and appearance for the subgenus ; sides of 
prothorax oblique, rarely just perceptibly sinuate, before 
the basal angles ; latter more broadly rounded at apex than
