length, interspace between the tegmina very slightly less than half 

 the apparent length of the tegmina; distal extremity of the tegmina 

 arcuato-truncate, broadly rounding to the costal margin and more 

 narrowly to the sutural margin. Supra-anal plate very broad 

 trigonal, apex very blunt; cerci short, conical, distal portion slightly 

 elongate; ovipositor subequal to the combined length of the head, 

 pronotum and tegmina, the greatest proximal depth contained 

 slightly more than three times in the length of the same, moderately 

 tapering in the proximal two-thirds, moderately arcuate, dorsal 

 margin moderately arcuate, ventral margin with slightly more than 

 the median half of its length nearly straight, considerably arcuate 

 proximad, strongly arcuate distad, general angle of the margins 

 distad slightly more acute than a rectangle, distal fourth of the dorsal 

 margin with seven to eight teeth, low proximad and increasing in 

 length distad, erect, directed disto-dorsad, ventral margin with the 

 distal fourth armed with eight to nine spines, slightly increasing in 

 length distad, the extreme distal ones slightly hooked; subgenital 

 plate small, V-emarginate distad for about half of its length, the 

 portions of the plate laterad of the median emargination present as 

 acute trigonal lobes, the apex of which is slightly beyond the general 

 form of the lobe. Cephalic femora about one and one-half times the 

 length of the dorsum of the pronotum, more robust than in the male 

 sex. Median femora about a third again as long as the cephalic 

 femora. Caudal femora slightly more robust than in the male, 

 but of similar proportions. 



Paratypic Series. — A series of fourteen males and eight females 

 bearing exactly the same data as the type and allotype have been, 

 selected as paratypes.
