Type specimens: Male holotype and female para type, Chamberlin 

 collection, from Soco Falls, east of Cherokee, Jackson County, North 

 Carolina, collected on April 29, 1939, by Nell B. Causey. 



Diagnosis: A small, narrow-bodied subspecies of Cherokia georgi- 

 ana, the width less than 24 percent of the length, in which the tibio- 

 tarsal spur is absent from the male gonopod and the sides of the seg- 

 ments are brown or black instead of yellow. The solenomerite of the 

 gonopod is generally more elongate than in the other two subspecies; 

 the cyphopod a little more highly arched as seen in lateral aspect. 



Variation: Within the small geographic range occupied by this 

 subspecies, there is an appreciable amount of variation in minor details, 

 probably a reflection of evolutionary recency as well as of the rugged 

 terrain inhabited by ducilla. 



The smallest specimen examined is a male from Indian Gap in the 

 Smokies, measuring 27.5 mm. in length and 6.1 mm. in width; the 

 largest, a female from Soco Gap, 36.5 mm by 8.7 mm. The average of 

 several dozen male specimens is 30.5 mm. long and 6.5 mm. wide. 

 The w/l ratio ranges from 19 percent, in a male from Chimneys 

 Campground, near Gatlinburg, Tennessee, to 24.5 percent in a male 

 from Soco Falls, North Carolina. Two other males from that locality, 

 however, are much more slender, with ratios of 22.8 and 22.9 percent. 

 The Soco Gap population, typical in the nomenclatorial sense, is not 

 typical of the subspecies in most structural characters, but is represent- 

 ative enough to impose its name upon the population at large. The 

 w/l ratio averages about 22 percent in males from various localities 

 in the Great Smokies. 



There is likewise some variability in color pattern, with the median 

 dorsal row of spots chiefly affected. These spots may be either rather 

 broad or smaller than the lateral scries, apparently without respect 

 to elevation or locality. The most typical coloration is that described 

 in the following notes made from life at Indian Gap, Tennessee, on 

 August 4, 1958: 



Dorsum and head rich glossy black; legs, paranoia, and median 

 dorsal spots creamy white. Antennae brownish; sternites brown, 

 pleurites tan in females, dark brown in males, anal valves nearly black 

 in both sexes. Median spots lenticular in females, nearly complete 

 transverse bands in males, anterior collum spot wider than posterior, 

 but collum almost completely ringed in some males.
