1931] Carabidse from North Carolina and Tennessee 153 
mens, which I have not made types, from Highlands, N. C. 
(Blanchard Collection, Museum of Comparative Zoology.) 
This species may be distinguished from other Sphaero- 
deus as follows : 
Sides of prothorax near base broadly and distinctly, 
though not strongly, sinuate; elytra with numer- 
ous parallel carinae S. midticarinatus 
Sides of prothorax not sinuate, or, if sinuate, elytra 
without distinct parallel carinae 
All other species of Sphaeroderus 
The exceptionally narrow prothorax, and strong punc- 
ture on the head midway between the eyes in multicarinatus 
are also useful diagnostic characters. 
Multicarinatus is a geographical representative of Sphse- 
roderus bicarinatus Lee., which it replaces in the Smokies. 
As species go at present in the genus, multicarinatus is a 
specific form, diifering from bicarinatus (of which I have 
seen the type and numerous other specimens from the 
Black Mountains, N. C.) in being more slender, with the 
sides of the prothorax sinuate, with a constant puncture 
between the eyes (rarely present in bicarinatus ), and with 
better developed elytral carinae. However, I have seen 
intergrades between the two species — notably a specimen 
from Lake Toxaway, N. C., 3,000 feet, August 28, taken 
by myself. Notwithstanding Leng’s (1961, p. 41) opinion 
to the contrary, I think that Sphseroderus lecontei, bicari- 
natus, and multicarinatus are all geographical representa- 
tives of a single stock, and that when the genus is revised 
upon a sounder basis, the last two forms should be con- 
sidered as (very distinct) subspecies of lecontei. Until 
a revision can be undertaken, however, the three forms 
had better be kept apart. 
Nebria appalachia n. sp. 
A member of subgenus Nebria s. str., group XI of Ban- 
ninger’s (1925) “Die Nibriini.”
