MORGAN HEBARD 63 



Allotype. — 9 ; same data as type, hut taken July 28 to August 

 5, 1916. [Hebard Collection.] 



Agrees with male except in the following features. Size somewhat larger. Inter- 

 ocular space about four-fifths as wide as that between antennal sockets. Tcgmina 

 and wings slightly more elongate.^" Supra-anal plate moderately transverse, weakly 

 triangularly produced, with apex strongly but irregularly concave emarginate. 

 Subgenital plate scoop-shaped, with meso-distal portion narrow and strongly pro- 

 duced; lateral margins briefly straight to bases of cerci, there convex declivent, with 

 margin of declivent portions somewhat thickened and armed with numerous, 

 minute, stout, chitinous spines, biseriately arranged; from the distal extremities 

 of these declivent portions, the lateral margins are straight and convergent to near 

 the narrow apex, where they curve briefly and weakly ventrad to their juncture. 



General coloration buffy, tinged with buckthorn brown. Head buffy, with two 

 vertical lines on occiput, a broad band between eyes, a narrower band, convex 

 ventrad, between ocelli and maculations on face of blackish brown;"' ocelli small, 

 pale buffy, striking. ^^ Pronotum with disk pictured and dotted much as in acan- 

 thastylata, but these markings are more obscured, since, in the present material, 

 the disk is much suffused with cinnamon brown; marginal portions hyaline, with a 

 faint buffy tinge. Tegmina transparent, buckthorn brown, with cross-veinlets 

 distad and in area of dextral tegmen, concealed when at rest, conspicuously dark- 

 ened." Wings hyaline, with a very faint brown tinge, veins buckthorn brown, with 

 enlarged apices of costal veins cinnamon brown, while proximad of these a verj- faint 

 and narrow buffy suffusion is appreciable. Dorsal surface of abdomen and cerci as 

 in N. impar. Ventral surface buckthorn brown, limbs ochraceous-buff, with incon- 

 spicuous dots of dresden brown to prout's brown on tibiae and tarsi; ventral surface 

 of abdomen with an irregular proximal suffusion of blackish brown.

In addition to the type and allotype, the following paratypes 

 are at hand. 



""Tegmina with seven sinistral and six dextral discoidal sectors; wing with ulnar vein 

 showing four branches. 



"1 These markings are very weak and suffused in the male, clear cut and distinct in the 

 female. 



"- The pale ocelli often become discolored and almost indiscernablc in dried material. 

 This is true of the female before us. 



"^ This is more decided in the male before us, in which these veinlets are prout's brown.
