broad-ovoid, very prominent; antennae reaching to the tips of 

 the wings. Pronotum with the dorsum flattened, the greatest 

 caudal width of the same contained about one and one-half 

 times in its length; cephalic margin of the disk sinuato-truncate, 

 caudal margin moderately arcuate, lateral angles rounded but quite 

 apparent, middle of disk with an impressed U-shaped figure which is 

 connected with the caudal margin by a very faint median sulcus; 

 lateral lobes with the greatest depth subequal to the greatest length, 

 cephalic margin gently arcuato-emarginate, ventral and caudal 

 margin regularly and broadly arcuate, humeral sinus rectangularly 

 incised. Tegmina about one and one-half times the length of the 

 body, regularly lanceolate, the greatest width contained slightly more 

 than five times in the length, apex well rounded; pattern of the 

 tegminal cells similar to that found in many of the other species of

the genus; median vein diverging two-fifths the distance from the 

 base of the tegmen, furcate, reaching the sutural margin very shortly 

 before the apex; tympanum with the greatest width contained one 

 and one-half times in the length of the same, stridulating vein slightly 

 arcuato-oblique, sutural margin broadly rounded at the apex of the 

 same vein. Wings with the exposed portion surpassing the tips of 

 the tegmina by about the length of the head and pronotum. Cephalic 

 and median femora unarmed on the dorsal margin, tympani of the 

 cephalic tibiae exposed. Caudal femora about two-thirds the length 

 of the tegmina, moderately inflated proximad, ventral margins armed 

 with one (internal) or two (external) spines distad; caudal tibiae 

 distinctly surpassing the femora in length. Disto-dorsal abdominal 

 segment with the distal margin arcuato-emarginate mesad, the 

 median portion of the segment with a broad longitudinal sulcus; 

 supra-anal plate acute-trigonal; cerci elongate, tapering, moderately 

 curved mesad, the apex slightly hooked and faintly enlarged, covered 

 with erect hairs ; subgenital plate with the median portion somewhat 

 produced, sharply narrowing, the distal extremity deeply V-emargi- 

 nate, no styles present.
