with posterior corners caudally produced, anterior corners rounded, 

 scapulorae entirely marginal, peritremata flat but prominent, the 

 pores rather large and located in deep pits. Posterior edge of all 

 paranota essentially straight, without basal lobes. Paranota of seg- 

 ment 19 small, broadly rounded lobes; epiproct small, partially 

 retracted into preceeding segment, of the usual subtriangular profile. 



Paraprocts glabrous, smooth, nearly flat, with prominent elevated 

 median edges, the ventral seta set on a tiny tubercule slightly removed 

 from the rim, the dorsal seta set on an enlargement of the rim near 

 its dorsal end. Hypoproct large, smooth, strongly flattened, depressed 

 toward lateral ends, semicircular in outline with a distinct median 

 apical projection; paramedian setiferous tubercules small, removed 

 from the edge, the setae very long. 



Ventral surface of prozonites smooth, separated from metazonites 

 only by a fine, indistinct groove. Legs set on prominent subcoxal 

 elevations, but no distinct elevated podosternum formed; caudal 

 margin of sternum broadened medially, with a small but distinct 

 raised rim. All sternal areas smooth and glabrous, no subcoxal spines 

 formed. Sterna of midbody segments about 1.5 mm. wide, legs of 

 both pairs equally separated. Coxae much shorter than prefemora 

 and without trace of distal spine; prefemoral spine very short and 

 acute, both coxa and prefemur with 2 or 3 ventral macrosetae; femora 

 elongate, clavate, postfemora distinctly longer than broad, tibiae 

 twice as long as broad; tarsi longer, set with numerous erect setae 

 increasing in length toward end of segment ; pretarsi long, slender, and 

 compressed, % as long as tarsi. Legs relatively long, the distalmost 

 4 podomeres visible beyond paranota when extended laterad. Length 

 relationships of podomeres: 3>6>2>5>4>-l. 



Interzonal furrow distinct down sides of segments, best defined in 

 front of anterior stigma; lateral surfaces of segments smooth, unmodi- 

 fied. Stigmata similar in shape, the anterior stigma somewhat larger 

 than posterior, slightly elevated but without flared rims, both stigmata 

 in contact with the dorsal coxal condyle. 



Anterior legs unmodified. Sterna of segment 5 with 2 low para- 

 median knobs between the 4th pair of legs, other sterna not modified. 



Gonopod aperture moderate in size, transversely oval, posterior 

 edge with very low marginal rim. Sternal surface between 8th pair of 

 legs depressed only at center. Gonopods relatively large, of the 

 form as shown in figures 8 and 9. 



Female (from Roan Mountain, Tenn.) : Body length ca. 28 mm., 

 greatest width 6.3 mm., W/L ratio 22.5%. Similar to male in most 

 details of body structure and color pattern. Body proportionately
