the fastigium of the vertex slightly acuminate, about as long as the 

 distance between the eyes, the lateral margins raised so as to form a 

 well-defined wall in advance of a bordering groove, the disk well 

 rounded, without a longitudinal median ridge. Beneath this bounding 

 carina are located the elongate, slightly arcuate lateral foveolae, which 

 are acuminate anteriad. Eyes rather prominent, pyriform, about as 

 long (o 71 ) or a little shorter than (9) the anterior genicular groove 

 below them. Antennae decidedly ensiform, somewhat longer than 

 the combined length of the head and pronotum. Frontal costa rather 

 prominent, deeply sulcate; the head viewed laterally with the front 

 quite strongly retreating, straight; lateral carinae prominent, sharp, 

 continuous to the base of clypeus. Pronotum compressed and with 

 the sides parallel on anterior lobe, the hind lobe rather strongly 

 divergent, the lateral carinae as well as the median sharp, prominent, 

 cut about the middle by the last transverse sulcus; anterior lobe 

 sparsely and the posterior one closely punctulate, the hind margin 

 widely and roundly angulate. Tegmina in both sexes extending be- 

 yond the tip of the abdomen, in the male very wide on the apical 

 half, in the female normal, gently obliquely truncate at apex, with a 

 well-defined intercalary vein in the female, but a very poor one in the 

 male. Wings of male with the costal area very wide and provided 

 with twelve or thirteen transverse parallel veins, giving to this portion 

 a very conspicuous fenestrate appearance. Posterior femora only 

 moderately robust, surpassing the tip of the abdomen in both sexes; 

 hind tibiae eleven-spined externally. Last ventral segment of male 

 abdomen short, acuminate; cerci about as long as the supra-anal 

 plate, slender, tapering but little, the apex blunt; interspace between 

 the mesosternal lobes quadrate or subquadrate, somewhat narrower 

 than the lobes themselves. 



General color variable, but possibly never to any extent green, 

 usually testaceous, brunneous, or fuscous, varied more or less promi- 

 nently with darker and lighter lines, flecks, and mottlings. Eyes 

 ferruginous or castaneous; upper edge of sides of pronotum longi- 

 tudinally banded with piceous, partially crossing to the disk on the 

 hind lobe, the lateral carinae pallid. Occiput, disk of pronotum, and 

 dorsal field of tegmina usually pallid; disk and costal area of tegmina 

 generally brown or fuscous, mottled, or maculate with pallid, but 

 sometimes only the longitudinal veins dark and the remainder pallid 

 or testaceous. Legs testaceous, more or less varied with fuscous;
