County, South Carolina. The sole North Carolina record is a male from 

 an unspecified locality in the mountains, which Hoffman surmised was 

 probably either near Tryon, Polk County, or "in Macon County between 

 Franklin and Clayton, Ga." 



In the summers of 1975 and 1976 we discovered P. c. incursus in moist 

 seepage areas in the Kings Mountain region of North Carolina 

 (Cleveland and Gaston counties), just across the border from South 

 Carolina, and can now confirm its occurrence in the state. This area 

 might be the one referred to previously, as it consists of several peaks over 

 300 m, two of which, the Pinnacle of Kings Mountain and Crowders 

 Mountain, rise to 520 m and 495 m, respectively. However, the region is 

 located in the south-central Piedmont Plateau Province, about 88.5 km 

 east of the Blue Ridge Front, and lies within the range postulated by 

 Hoffman for the subspecies. Nevertheless, the prior North Carolina 

 record could conceivably be from the Kings Mountain region, since to our 

 knowledge Pachydesmus has never been authentically collected from the 

 Appalachian Mountain portion of the state. 



Wray (1967) reported "Pachydesmus retrorsus" from "probably valley of 

 French Broad River," western North Carolina. The specimen that he 

 cited, however, was the questionable one from North Carolina that 

 Hoffman had earlier (1958) identified as P. c. incursus. Thus, P. retrorsus 

 does not occur in North Carolina and is hereby deleted from the fauna of 

 the state. This error could have been avoided by simply reviewing 

 Hoffman's paper, which also reduced P. retrorsus to a subspecies of P. 

 crassicutis. 



In the summers and springs of 1976-1977 the senior author collected P. 

 c. incursus from 16 localities in the South Carolina Piedmont and two in 

 the lowland region of the Coastal Plain. Of the Coastal Plain specimens, 

 those from Barnwell County were found along the edge of a swamp in 

 association with Sigmona latior hoffmam Shelley, and the female from 

 Jasper County was found under moist leaves in a live oak thicket. In the 

 Piedmont, the milliped was encountered primarily in hardwood localities 

 near water sources but was also taken from pine areas with thick vines 

 and undergrowth. One female from Newberry County was discovered un- 

 der pine-bark mulch on a walkway at Molly's Rock Picnic Area, Sumter 

 National Forest, in a primarily pine forest. These collections indicate that 

 the subspecies is common in the Piedmont and Coastal Plain of South 

 Carolina and can probably be collected from similar habitats south of the 

 Savannah River in Georgia.

 incursus are listed below. Except for two samples in the Florida State
