one-half times in the length ; costal margin gently arcuate distad to 

 the rather narrow suboblique rotundato-truncate apex; tympanum 

 slightly longer than the disk of the pronotum, its greatest width 

 subequal to the caudal width of the latter, stridulating vein short, 

 slightly oblique, greatly thickened. Prosternum 

 long bispinose; lobes of the mesosternum and 

 metasternum slightly acute-angulate. Disto-dorsal 

 abdominal segment with the distal margin arcuato- 

 emarginate, subacute and faintly tuberculate laterad, 

 strongly arcuato-emarginate at the base of each 

 cercus; supra-anal plate trigonal, slightly elongate, 

 lateral margins moderately concave, apex narrowly 

 rounded, medio-longitudinal sulcus pronounced; 

 cerci with the shaft robust, the surface of same 

 subpustulate, ventral extremity bent mesad and 

 slightly proximad, sinuate, acuminate, with a strong 

 terminal spine, dorsal extremity with a shorter 

 process, which is, however, similarly developed and 

 with a slightly longer spine; subgenital plate 

 moderately broad, tricarinate ventrad, the lateral 

 carinse heavier and more rounded than the median, being the trunks 

 bearing the styles, which latter are brief, rather blunt, and faintly 

 tapering, distal margin of plate obtuse-angulate emarginate. Cephalic 

 femora about four-fifths as long as the dorsum of the pronotum, 

 ventro-cephalic margin distad with two to three spines, ventro- 

 caudal margin unarmed; cephalic tibia? unarmed dorsad. Median 

 femora a fourth longer than the cephalic femora, margin similar. 

 Caudal femora about three-fifths as long as the tegmina, slender, 

 armed on the distal half of each of the ventral margins with six 

 spines. 



General color tawny-olive. Head with the dorsum of the fastigium, 

 occiput, and postocular region multilineate with weak bister lines, 

 lateral margins and apex of fastigium bordered with cream-buff, 

 ventral surface of fastigium with a faint purplish tinge, but no black; 

 eyes seal-brown; antenna? of the general color. Pronotum with the 

 dorsum very weakly and the lateral lobes, particularly dorsad, more 

 strongly washed with warm sepia, the position of the lateral angles 

 indicated ])y chamois lines. Tegmina with the discoidal field 

 sprinkled with small points varying from blackish to seal-brown in 

 tone. Limbs unicolorous, spines narrowly tipped with blackish 

 brown.
