Spiracles all circular and of very nearly the same diameter through- 

 out length of body. 



First legs but little reduced, the second of normal size. 



Ventral pores in a broad band along caudal border of each anterior 

 plate, the band on more caudal segments dividing into two areas as 

 usual. 



Last ventral plate narrow, sides converging caudad; posterior end 

 of plate extended caudad and narrowly rounded. Coxopleurae of 

 segment bearing about 16 pores, large and small, on ventral surface. 



Anal legs in female ending in a large claw; about equalling the 

 penult legs in length and thickness. Anal legs in male strongly 

 crassate, thickest at middle of length; subdensely clothed with finer, 

 and moderately long hairs. 



Anal pores rather large, usually concealed from ventral side. 



Pairs of legs in female 41-43; in males uniformly 41. 



Length of female 27 mm.; width ad 1.2 mm. Length of male 

 22 mm. 



Localities. — Tallulah Falls and Bremen, Ga.; Taylor's, S. C; 

 Russellville, Tenn.; Brown's Summit, N. C; Natural Bridge, Va. 

 The type, a female, is from Arkansas. 



The female upon which the above description is almost wholly taken 

 is from Tallulah Falls. 



var. miura, var. nov. Agreeing with typical form excepting in its 

 apparently smaller size, which seems to approximate that of chiono- 

 phila, and especially in the greater shortness of the antennae which 

 likewise are very much in proportion and appearance like those of 

 chionophila. The antennae are mostly but three times, a little more 

 or less, as long as the head whereas in the typical form, as above 

 indicated, they are from nearly four to somewhat more than four 

 times as long. While some specimens seem to indicate intergrading, 

 in my material there are evidently two modes of length in the antennae. 

 It seems better, therefore, for the present at least to indicate the two 

 forms.
