specimens of the western beameri results; the latter species, how- 

 ever, having the cercus tapering in all but its distal third instead 

 of tapering in only the proximal half or slightly less. Another 

 male from Mount Sterling, North Carolina, has the distal portions 

 of the cercus unusually narrow, but this we believe is also attrib- 

 utable wholly to individual variation. It is therefore evident 

 that the male cerci are subject to some individual variation in the 

 present species and the same we find to be true for the other 

 species of the group. Although the form of the male cerci is the 

 most important feature in distinguishing the species and although 

 such variation occurs in probably all of the species, we are satisfied 

 that, though the separation of the species and races is thereby 

 made very difficult, sufficient series will always show whether 

 individual variation, racial or specific status is actually indicated. 



The apical tubercle of the male subgenital plate is slightly 

 transverse, frequently dimpled, and in two specimens of the large 

 series before us it is distinctly bituberculate. Such differences 

 are wholfy attributable to individual variation. 



The caudal femora have the dark markings often rather broad 

 in the males but never fusing vent r ad. These markings individu- 

 ally vary from weak and diffused to almost obsolete in the females. 



The male subgenital plate is blackish except in the narrow sub- 

 chitinous basal portion, the preceding sternite being pale with 

 distal portion alone blackish, which forms a very narrow trans- 

 verse triangular marking. 



In addition to the twenty nine specimens we originally recorded 

 as calloplus, from West Point, New York; Plainfield, New Jersey; 

 Collison Ridge and Snickers Gap, Virginia; White Sulphur 

 Springs, West Virginia, and Mayland, Tennessee, the following
