were black and without stripes. In both areas the stripe and/or paranotal 
color was yellow and did not vary through shades of orange-red, as 
reported by Shelley for the nominate subspecies and intergrades. 
Since this is the first report of unstriped specimens in the zone of in- 
tergradation, the gonopods of 18 striped and 13 unstriped males were ex- 
amined for possible differences. Depth of the flange and broadness of the 
distal curvature of the telopodite varied, but the flange always extended 
below the tip of the telopodite (Fig. 60). The subterminal tooth varied in 
prominence and was double in two individuals (Figs. 60-62), and the 
prefemoral process ranged from simple to bifurcate with variation in the 
relative lengths of the components, although the vertical branch was 
always larger (Figs. 63-64). All are typical intergrade variations and do 
not correlate with either color pattern. Thus, the solid black metatergal 
color is interpreted to represent the nominate subspecies trait, just as 
some intergrade gonopods more closely resemble those of one subspecies 
than the other two. 
DISCUSSION 
Seasonal Variation of the Fauna 
Although the Kings Mountain region was not sampled quanti- 
tatively and only limited conclusions can be drawn concerning numbers 
of species present in each season, the area was studied with sufficient in- 
tensity to reflect general trends in seasonal differences (Table 3). The 
overall abundance of millipeds increased from April to October, with 
only two species, Narceus americanus and Auturus erythropygos, present 
as both adults and juveniles in all three months. Adults of other species 
varied seasonally, with juveniles present simultaneously or in other 
months. The more common species that particularly exemplify these 
seasonal variations are discussed by month below. 
Diplopods were least abundant in April. Adults of Pseudopoly- 
desmus branneri and Boraria stricta, and juveniles of Oxidus gracilis, 
dominated the fauna, while adults and juveniles of N. americanus, and 
adults of Cambala annulata and A. erythropygos were moderately abun- 
dant. Adults of Ptyoiulus ectenes, Delophon georgianum, and Deltotaria 
lea were less common, and juveniles of these species were absent or nearly 
so. Only a few specimens of the remaining species were found. Adults of 
D. georgianum, P. branneri, B. stricta, and D. lea, and juveniles of Stri- 
aria sp., O. gracilis, and B. stricta were more numerous in April than in 
any other month. Two species, Brachyiulus lusitanus and Trichopetalum 
dux, were collected only in April. 
A different group of diplopods dominated the fauna in July. Narceus 
americanus, Abacion magnum, O. gracilis, A. erythropygos, Pachydesmus 
crassicutis incursus, and Sigmoria latior were the prevalent adult forms, 
while Polyxenus fasciculatus, Ptyoiulus sp., and N. americanus were com- 
mon in immature stages. Intermediate numbers of A. erythropygos and
