MILLIPED GENUS CHEROKIA — HOFFMAN 245 



caudal rim between 8th leg pair set off by a low marginal ridge, the 

 adjacent sternal area narrow and depressed. Gonopods rather small, 

 the coxae normally retracted into the body, the elongate, nearly 

 straight telopoditcs exposed, parallel to each other, directed cephalad 

 between the legs of the 6th segment. Prefemur elongate, setose, 

 the setae becoming longer distally, coxal side provided with a short, 

 acicular prefemoral process. Gonopod in mesial aspect almost 

 identical with that of C. g. laiassa (fig. 4,6), the distal end with a rather 

 short SLibtriangular solcnomerite and nearly straight subapical process 

 (fig. 4,e). 



Epigynal region of 3d segment of females without special lobes or 

 other modifications. Cyphopods elongate-reniform in outline, the 

 basal two-thirds with scattered large setae, the operculum with longer 

 and more profuse vestiture. Width of outer valve nearly uniform, 

 not somewhat greater near the base as apparently is the case in the 

 other two subspecies (fig. 5,a). 



Dorsum glossy blackish, with the paranotal and broad median 

 series of spots yellowish orange, the underparts whitish gray with 

 the legs becoming yellow distally. The median dorsal spots are 

 sublimate, and extend laterad almost to the paranota. 



Variation: The body form of the typical subspecies is quite uni- 

 form over its range. Some minor geographic variation can be noted, 

 however, for several structural details. 



Male specimens from eastern Alabama and most of Georgia are 

 provided with fairly conspicuous subcoxal sternal knobs on the 7th 

 segment. These become reduced in the mountain region and are 

 obliterated in the intergrade population of western North Carolina. 

 The solcnomerite of the male gonopod tends to increase in length 

 northward. 



The color pattern is somewhat variable. The population of 

 extreme eastern Alabama appears to be bimaculate. In central 

 and northern Georgia the median spots are enlarged and lunate in 

 form and in the males often contact the lateral series of spots and 

 forming transverse bands of j'ellow. In southeastern Tennessee the 

 three rows of spots are of about the same size, except in the western 

 foothills of the Great Smokies in Blount County, where a local popu- 

 lation has developed striking crossbands. It is of some interest to 

 note that in the same region specimens of the normally trimaculate 

 Apheloria montana are likewise transversely banded, and we may 

 have a case of mimicry or a very improbable coincidence. 



The largest male specimen of C. g. georgiana measured is from 

 Banks County, Georgia: 9.2 mm. wide and 34.5 mm. long. The 

 largest female is from Pickens County, South Carolina: 9.0 mm. by 

 37.0 mm.
