a curved row of eleven setae around each antenna base ; ventral surface 
with a few scattered setae on the anterior median portion. 
Type locality: Devils Den Kitchen Cave, Washington County, 
Arkansas, IX-9-’59, Tecklin, Hedges and Darland coll. Also taken 
from Granny Dean and Devils Den Caves, Washington Countv.

Discussion 
The number of eyes varies considerably, most specimens having 
five per side. However, many have four per side ; in such cases it is 
the posteriormost eye of the anterior three which is missing, and the 
position of this eye is variable even when it is present. The tenent 
hair varies from acuminate to markedly clavate. 
The taxonomic position, name and limits of this species are all 
moot. The species is clearly distinguished from the form called here 
P. duodccim punctata. The antennae of duhia are longer, and the eye 
number typically different. The shape of the eye patch and distribution 
of the eyes are also different, as is the structure of both mucro and 
unguis. The question of the relationship between this form and 
Wray’s collina or Guthrie’s Lepidocyrtus decemoculatus is less easily 
settled. The present species appears to differ from collina in (i) the 
number of eyes (six vs. five per side typically) ; (2) the relative 
lengths of abdominal segments three and four ( collina one: four, d.ubia 
one: five + ) ; (3) antennal ratios; and (4) the comparison of lengths 
of the manubrium and dens. In addition, Wray’s figures show the basal 
spine of the mucro not reaching the anteapical tooth and the unguis
