REVISION OF BORARIA AND GYALOSTETHUS — HOFFMAN 317 



could measure precisely was about 24 mm. in length, but it is entirely 

 possible that local populations may exist with even smaller individuals. 

 The coloration of B. brunnior is not singular, for in the description of 

 Chamberlin's previously named Aporiaria geniculata occurs the 

 statement "Dorsum black or nearly so [italics mine], with the keels 

 yellow, the tergites in part also narrowly margined with yellow across 

 caudal border." In the specimens of B. media that I have seen, 

 brownish coloration occurs sporadically, and occasional specimens, 

 particularly recently moulted ones, tend to show transverse tergal 

 stripes of yellowish. 



My inclination is to regard the name B. brunnior as a junior synonym 

 of B. media, but perhaps it is best to withhold final judgment until 

 the holotype, or fresh topotypes, can be studied. Possibly B. brunnior 

 can be retained as a subspecific designation. 



Range. — Southern Appalachian region from Vnginia to Georgia. 

 Two of the species are confhied to western North Carolina and extreme 

 eastern Tennessee. The generic distribution coincides closely with 

 the Southern Section of the Blue Ridge Physiographic Province. 



Species. — Thi*ee are recognized as valid, along with a possible 

 fourth, which was discussed in a preceeding paragraph. It seems 

 unlikely that any undescribed species of Boraria remain to be found. 



Key to the Species of Boraria 



1. Epicranial suture poorly defined, not branched between the antennae; 



metatergites with several transverse rows of conspicuous tubercules; 

 dorsum glossy black with bright lemon-j-ellow paranotal spots, sides of 

 segments also black; distal end of gonopod subhastate in shape (fig. 3). 



stricta Brolemann 

 Epicranial suture distinct, branched between the antennae (fig. 14) ; meta- 

 tergites smooth and polished except for faint rugosity at bases of paranota; 

 dorsum dark brown to blackish, sides of segments lighter, paranotal spots 

 orange or red; distal end of gonopod slender, acuminate (fig. 8) .... 2 



2. Coxae not spined; paranota set high on sides and not strongly depressed; 



dorsum blackish, with reddish paranotal spots; epicranial suture without 



a row of punctures media Chamberlin 



Coxae with prominent ventrally directed terminal spines (fig. 16); paranota 

 strongly depressed, the dorsum thus appearing nearly terete; dorsum 

 blackish, with paranotal spots and transverse tergal bars orange yellow; 

 epicranial suture with a row of small punctures . . . deturkiana Causey
