subequal in width except for a slight infra-ocellar constriction in 

 the male, sulcate throughout its length; lateral facial carinse marked, 

 slightly diverging ventrad in the male, decidedly arcuate divergent 

 ventrad in the female; eyes quite prominent in the male, much 

 less pronounced in the female, subovate, in length distinctly exceed- 

 ing the infra-ocular portion of the gense in the male, slightly exceed- 

 ing the same in the female; antennae slightly more than twice the 

 length of the dorsum of the pronotum, joints moderately elongate, 

 proximal joints slightly depressed, in consequence giving a 

 faint subensiform appearance to the appendage. Pronotum with 

 the greatest dorsal width contained one and one-half times in 

 the length; cephalic margin of the disk with a broad and very blunt 

 obtuse angulation, caudal margin obtuse-angulate in both sexes, 

 the immediate angle having a distinct, though small, rounded 

 emargination ; median carina distinct, subequal in the male, slightly 

 arcuate on the prozona in the female; disk of the metazona flattened,

of the prozona rounding into the lateral lobes, caudal transverse 

 sulcus strongly impressed, the two ce})halic transverse sulci 

 marked but not cutting such a pronounced gap in the median carina 

 as the caudal one; prozona and metazona subequal in length, the 

 prozona very slightly longer in the male; lateral angles very distinct, 

 ])arallel, and horizontal on the metazona, descending on the prozona in 

 a curve to the ventro-cephalic angle, this portion of the lateral angles 

 being much more pronounced in the male than in the female ; lateral 

 lobes with their dorsal length very greatly exceeding their depth, 

 ventral margin sinuate obtuse-angulate, ventral angles rounded 

 obtuse. Tegmina about three and a half (female) to four (male) 

 times the length of the dorsum of the pronotum, acute lanceolate, 

 the costal lobe more pronounced in the female than in the male, the 

 distal fourth of the costal margin gently rounding to the acute apex, 

 sutural margin straight with a slight obhque truncation near the 

 apex; intercalary area irregularly reticulate. Wings very sUghtly 

 shorter than the tegmina when in repose. Prosternal spine distinctly
