Type. — cf; Flag Rock Pass, Warm Springs Mountain, Bath 

 County, Virginia. Elevation 2900 feet. July 6, 1916. (M. 

 Hebard). [Hebard Collection Type no. 1263]. 



Size slightly below medium, form graceful. Vertex narrow, 

 concave between the distinct lateral carinae; frontal costa 

 depressed only around median ocellus. Pronotum with a very 

 fine percurrent medio-longitudinal carina, principal sulcus alone 

 distinct on dorsum, caudal margin convex on each side leaving a 

 very small median angulate emargination. Prosternal spine 

 rather slenderly conical and sharply rounded at apex. Tegmina 

 ovate, shorter than pronotum, separated by a distinct interval. 

 Apex of abdomen definitely thickened. Furcula very small, 

 springing from thickened areas on tergite, very slightly longer 

 than basal width with rounded apices. Supra-anal plate shield- 

 shaped, medio-longitudinal sulcus percurrent, lateral portions 

 concave, paired distal carinae short prominent and divergent 

 cephalad. Cercus elongate, shaft slender, apical portion as 

 broad as base with disto-dorsal margin broadly rounded and 

 disto-ventral portion moderately produced disto-ventrad and 

 bluntly rounded acute-angulate. Penis as given in above key. 

 Subgenital plate with a small but sharply defined blunt subapical 

 tubercle. 



Allotype. — 9 ; same data as type. [Hebard Collection]. 



Larger and more robust than male, but the contrast between 

 the sexes is decidedly less than in tribulus. Vertex broader. 

 Prosternal spine heavier but with apex as sharply rounded. Teg- 

 mina even shorter in proportion to pronotal length. Ovipositor 

 jaws medium, with moderate distal curvature, dorso-external 

 margins of dorsal valves toothed.
