epigean. The Kentucky localities are at elevations of 800 to 980 feet (240 
to 300 m) and those in Tennessee at 1100 to 2200 feet (335 to 670 m). The 
series are relatively small except in the case of Hydens Cave, where about 
80 specimens were collected far back in the cave on wet, rotting leaves 
beside a deep pool. 
Trechus (Trechus) mitchellensis Barr

North Carolina; type deposited in USNM. 
Trechus mitchellensis is known from three localities in the Black Moun- 
tains (Celo Mountain, Mt. Mitchell, and Big Tom, all in Yancey 
County), from the Pinnacle, where the Blacks intersect the Blue Ridge 
(McDowell County), and from Balsam Gap, where the Blacks join the 
Great Craggy Mountains (Buncombe County). All localities are at eleva- 
tions between 4800 and 6500 feet (1460 to 2000 m) northeast of Asheville, 
North Carolina. This species is moderately large (3.6-4. 2 mm), closely 
similar to T. schwarzi scopulosus , with which it is both sympatric and syn- 
topic. From T. s. scopulosus it is distinguished by the sharp ventral cusp on 
the apical knob of the aedeagus and by the pronotum sides, which are 
very briefly but distinctly sinuate before the small, right, hind angles. The 
usual microhabitat is under moss carpets in spruce-fir forest.

Trechus carolinae is a very large (4. 5-5.0 mm) species for the Appala- 
chian area. It is relatively rare, inhabiting deep spruce and fir needle duff 
near the summits of the Black Mountains. On Mt. Mitchell I have taken a 
small number of specimens by prying back the duff layer at the bases of
