straight, subparallel, extending between branches of colpocoxites, median 
projection short, broad, apically truncate (Fig. 8). 
Holotype about 27 mm long (broken), coloration as described for P.f. 
ingens, ocelli pigmented, 21 in five rows. Dorsolateral knobs of anterior 
segments less prominent than in the other three races, and not elevated. 
Metaterga of most segments with two low but distinct convexities 
between median suture and dorsolaterial ridges, surface of these areas 
distinctly coriaceous in contrast to the nearly smooth metaterga of other 
subspecies. 
Aside from the holotype, I have examined a female (NCSM A2598) 
from Cliff Ridge near Blowing Springs, 3.3 mi. NE of Nantahala, Swain 
County, North Carolina; L. Hubricht leg. 16 May 1961. This specimen 
had been identified by Dr. Shear as P. cottus but was not cited in his 
monograph (possibly because of the usual uncertainty in the identifica- 
tion of single females). It is probably from the immediate vicinity of the 
type locality. 
ACKNOWLEDGMENTS. — My sincerest thanks are expressed to 
Dr. Thomas C. Barr, Jr., Dr. Jerry A. Payne, and Mr. Leslie Hubricht 
for presenting me with most of the material upon which this paper is 
based. Dr. Rowland M. Shelley kindly loaned the specimens of P. /. 
nantahala and allowed me to describe it. Dr. Shelley and Dr. J. E. 
Cooper performed much-appreciated service in removing numerous 
rough places from the manuscript.
