lateral aspect, form of disk similar to that of male but less constricted 

 mesad; cephalic margin emarginato-truncate, caudal margin moder- 

 ately arcuate; lateral lobes with their greatest depth contained 

 slightly less than twice in the dorsal length of the same, margins of 

 the lateral lobes as in the male. Tegmina semi-ovate, reaching the 

 caudal margin of the metazona, the greatest width distinctly greater 

 than the apparent length, interspace between the tegmina about

two-thirds that of a single tegmen. Cerci brief, conical, acute; 

 ovipositor subequal to the median femora in length, arcuate in 

 general form, moderately slender, tapering in proximal two-thirds, 

 ventral margin less arcuate than the dorsal one aside from a decidedly 

 arcuate distal portion, distal third of dorsal margin with eleven to 

 twelve teeth increasing in size distad, ventral margin with nine to ten 

 teeth on distal fifth, the extreme distal one slightly recurved; sub-

genital plate almost divided to the base by a V-shaped emargination, 

 the lateral sections developed into very acute trigonal lobes- 

 Cephalic femora slightly less than twice as long as the disk of the 

 pronotum. Median femora twice the length of the disk of the 

 pronotum. Caudal femora almost two and one-half times the 

 length of the cephalic femora.
