MILLIPED GENUS CHEROKIA — HOFFMAN 243 



defined fault line. Dorsolateral rugosity of metazonites not carried 

 over onto prozonites, which are completely smooth. Aside from cori- 

 aceous texture, the metazonites are provided with minute setiferous 

 tubcrcules, most conspicuous posteriorly, which tend to form three 

 irregular transverse rows. The caudalmost of these rows normally 

 consist of about 22 (up to 28 in some cases) tubercules, three widely 

 separated near the caudal paranotal edge, and 14 to 16 set much closer 

 across the dorsum itself. The other two rows are less regular in num- 

 ber and distribution, the widely spaced tubercules ranging from 10 to 

 about 16. 



Epiproct evenly conical in dorsal aspect, its surface mostly smooth 

 except for some basal striations and distinct setiferous tubercules, the 

 appex decurvcd slightly and bearing four terminal compound setae. 

 Peripheral areas of disc of anal valves vertically costate, the median 

 area elevated and smooth, with a single paramedian setiferous socket. 

 Free edges of valves produced into distinct marginal swellings, becoming 

 thicker upwards, the point of greatest breadth including the marginal 

 seta. Hypoproct a broadly oval plate (fig. 3,(1), the surface smooth 

 and unmodified, paramedian apical setae widely separated from each 

 other and well removed from the caudal margin of plate. Apical 

 projection very small or wanting. 



Pleural areas unmodified, surface finely granular except for the 

 caudal edge, which is set off as a depressed, smooth, parallel-sided 

 margin, the edge strongly sigmoidally curved ventrad, ending on dorsal 

 curve of coxal socket. Interzonal furrow more definitely formed down 

 sides and across venter. 



Sternal areas smooth and glabrous, tending to form a raised area 

 (podosternum) between the legs but this area sloping gradually 

 cephalad to the interzonal furrow. Each podosternum divided by 

 a vague transverse groove which becomes accentuated laterally where 

 it is prececded by a low conical knob formed by the sternum at the 

 base of the anterior leg pair. Sternum between posterior leg pair 

 projecting shelflike caudad, its margin transverse except for the 

 strongly produced corners, which become increasingly larger and more 

 acute back to the 18th segment (fig. S,d). Sternum of 7th segment 

 flat, without subcoxal spines or very low ones. Midbody legs sepa- 

 rated by a distance up to 2.5 mm., equalling or exceeding length of 

 prefemur. Sternum of 4th segment of male produced into two low 

 rounded knobs between the legs, anterior leg pair of 5th segment 

 separated by two larger, more transverse, and cephalically directed 

 processes. Sternum of 6th segment broad, flat, unmodified. 



Legs long, those of midbody segments up to 9.0 mm., the 

 joints in decreasing order of length, 3-6-2-5-4-1. The basal two 

 joints glabrous but for a ventral row (coxa) or field (prefemur) of
