just distal to cingiilum distinctly swollen; a small, thin flange present 

 on caudomesial surface of postcingular portion of telopodite at about 

 midpoint of its length (this flange not present in the closely related 

 species separanda) ; extreme distal portion of telopodite tapering to 

 acute point. Variable number (usually 1-4) of small spines present 

 on precingular portion of telopodite at about midpoint of its length; 

 size of spines variable. Prefemoral spine moderate. 



Color variable; very dark brown above with entire caudal edge of 

 tergites brightly colored, these bands sometimes bright red (Riner 

 specimens and some Blacksburg specimens, including the holotype), 

 sometimes bright lemon yellow (West Virginia specimens) , and some- 

 times red on paranota and yellow on dorsum or red on anterior seg- 

 ments and yellow on posterior 3 or 4 segments including the telson 

 (some Blacksbm-g specimens) ; a light median spot on cephalic edge of 

 collum; underparts straw-colored. 



Type locality: Blacksburg, Montgomery County, Va. 



Type specimens: Male holotype collected by W. C. Lund, June 

 26, 1956. Male and female paratypes collected by L. T. Eichardson, 

 June 26, 1956, at Riner, Montgomery County, Va. All type material 

 is in the U. S. National Museum. 



Other distribution records: 



West Virginia: Summers County: about 10 miles southeast of Hinton on 

 Route 12, July 16, 1956 (2 c?, 1 ?), Hoffman. Virginia: Montgomery County: 

 Blacksburg, Dec. 9, 1956 (2 c?), Hoffman. Three males with no collection labels 

 found in the collections of the Biology Department of Radford College; the evi- 

 dence seems to indicate that they were collected near Radford, Va., in the early 

 part of this century. 



Discussion: Brachoria calcaria resembles B. separanda in the gen- 

 eral form and shape of the male gonopods, and I at first considered 

 describing it as a subspecies of the latter species. Further study in- 

 dicated that this was not advisable, however, inasmuch as there ap- 

 pears to be no evidence of intergradation of the distinguishing charac- 

 ters. The known ranges of the two species are not far distant from 

 one another yet all specimens are fully distinct. 



The enormous variation in color in this species is of special interest. 

 It serves to call attention to the very close relationship of red and 

 yellow pigments in many millipeds.

Diagnosis: Distinguished from all other species of the genus except 

 tenebrans by the prominent right angle bend in mesial view of the post- 

 cingular portion of the telopodite of the male gonopod, the distal por-
