Subgenital plate scoop-shaped, roundly produced distad on each 

 side in a small area, from a socket on the ventral surface of which 

 spring the styles, between these the caudal margin of the plate is 

 roundly emarginate to the median point, where there is a rounded 

 projection, deeper than wide and longer than deep. Styles stout, 

 straight, cylindrical, two and one-half times as long as broad, with 

 apices bluntly rounded. Femoral genicular lobes as follows; 

 cephalic internal and median internal produced in a small but 

 stout tooth, cephalic external and median external triangularly 

 produced with apex rounded, caudal all strongly bispinose. Ventral 

 femoral margins armed (in the pair at hand) as follows. Cephalic 

 internal 5 to 6, cephalic external 4 to 5, median internal 2 to 2 

 (proximal), median external 5 to 6, caudal internal 1 to 3, caudal 

 external 7 to 8. 



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



Agrees closely with male, differing as follows. Size larger. 

 Pronotum with caudal portion of disk decidedly shorter and caudal 

 margin truncate, weakly convex, rather than broadly and evenly 

 rounded. Ovipositor moderately elongate, slender, unarmed, 

 gradually curved dorsad and tapering to the acute apex. Sub- 

 genital plate short, truncate-bilobate. 



General coloration shining black, except in the following areas. 

 Fastigium of vertex and two proximal antennal joints amber 

 brown. Eyes brussels brown. Clypeus ochraceous-tawny, be- 

 coming orange rufous on the labrum. Tegmina with all veinlets 

 conspicuously reed yellow. Ovipositor shading from black to 

 russet distad. Ventral surface of abdomen blackish brown. 

 Femora amber brown, in the female with median and caudal femora 

 weakly darkened proximad and distad. Tibiae ochraceous-buff, 

 the spines amber brown. Tarsi with dorsal portions of first two 

 joints ochraceous-buff, black in other portions.

The species is known from the pair here described. 



Anthracites zebra new species. Plate XVIII, figures 1 and 2. 



This is a small, pale species, showing a beautiful color pattern 

 of dark brown. It belongs to the same group as A. apoensis here 

 described and, though apparently nearest in relationship to that 

 species, differs strikingly in color pattern and male genitalic 

 features. 



In coloration alone it shows nearer agreement with A. femoralis
