electa shows some modification of this type, although in all other 

 respects it so closely resembles the type species Brachoria initialis 

 that it may in the futm'e have to be reduced to a subspecies of ochra. 

 The new species B. hqff?nani shows modification similar in some 

 respects to Anfraciogon tenebrans. Furthermore, a specimen of 

 tenebrans from northern Alabama does not exhibit as much modifica- 

 tion as does the type specimen of the species and appears in every 

 way typical of the genus Brachoria. 



Inasmuch as no character has been found by which Anjractogon 

 may be separated from Brachoria, it is my opinion that Anfraciogon 

 must fall as a synonym of Brachoria. 



Diagnosis: A xystodesmid genus with telopodite of male gonopod 

 bisected by a cingulum dividing it into proximal setose region and 

 distal glabrous region. Telopodite forming arc variable in both 

 size and complexity. Gonopod aperture subovoid, cephalic side 

 slightly indented. 



Body broad, length 3.5-4.9 times the width; length 30-52 mm.; 

 width 6.5-12.5 mm. Paranota wide, usually overlapping, those of 

 ninth segment often with caudolateral corners not produced caudad 

 or if produced, usually only slightly so. Paranotal swellings usually 

 not strongly developed, often almost lacking on collum and on 2d 

 segment. Repugnatorial pores distributed in normal manner for 

 the family, opening dorsally in paranotal swellings. Antennal sen- 

 sory cones, 4. 



Range: Southeastern United States: Alabama and Mississippi 

 north to southern Indiana, West Virginia, and extreme western Mary- 

 land, and east to southwestern Virginia and western North Carolina. 



Species: 25, two of which have an additional subspecies.
