Psyche 
[ December 
nessee side, 3,500 feet. 13 paratypes from Deep Creek 
(Bryson City), N. C., 2,000 feet. All specimens taken by 
myself. Holotype, allotype, and paratypes in the Museum 
of Comparative Zoology (No. 16434) ; paratypes in the 
writer’s collection. The Deep Creek specimens were washed 
from piles of drifted trash along the banks of the creek; 
they may have been carried down from higher altitudes. 
All the other specimens were taken among loose dead leaves 
( not in compact leaf mold) on the ground on forested 
slopes. 
The name I have used is derived from that of the Unica 
Mountains, of which the Smoky Mountains are a part. I 
completely failed to find this species outside of the Smokies. 
The various species of the subgenus Gastrellarius of 
Pterostichus may be tabulated as follows : 
1. Base of pronotum with numerous scattered punc- 
tures ; average size larger ; only 1 setigerous punc- 
ture over each eye in honestus and probably in 
Casey’s three species— 
honestus Say scolopaceus Csy. 
atronitens Csy. deficiens Csy. 
Base of pronotum not punctate ; average size 
smaller; 2 setigerous punctures over each eye 2 
2. Base of pronotum distinctly (and by actual meas- 
urement) wider than apex; form stouter and more 
convex; head proportionately smaller; elytral 
striae as a rule more distinctly punctate; length 
5.0 ( teste Casey) -6.8 mm blanchardi Horn 
Base of pronotum distinctly (and by actual measure- 
ment) narrower than apex; form more slender, 
much as in honestus; other characters opposed to 
those above; length 6.2-7.55 mm. unicarum Dari. 
I know Casey’s three species only from description. I 
am indebted to Mr. L. L. Buchanan for pointing out to me 
the interesting reduction of the supraoccular setse in Gas- 
trellarius honestus. The presence of an entire mentum tooth 
in this subgenus is also noteworthy.
