cephalic femora in length: median til)iae slightly longer than the femora; distal 

 spurs four in number, the ventral pair the larger. Caudal femora three- 

 fourths as long as the body, moderately bullate for three-fifths of their length, 

 the greatest depth contained slightly less than four times in the length of the 

 same, ventral margins unarmed, ventral sulcus broad, deplanate; genicular 

 spines one on each side (spines destroyed but sockets evident) ; genicular lobes 

 moderately elongate, rounded distad: caudal tibiae one and one-sixth times as 

 long as the caudal femora, relatively slender, nearly straight, dorsal margins 

 with four pairs of mobile spurs situated on the distal five-eighths of these mar- 

 gins, the spurs paired but with their bases not directly opposite, the spurs 

 faintlj' falcate with the apices slightly hooked, all the pairs excepting the distal 

 have the internal distinctly shorter than the external spur, distal pair small, 

 subequal; between the spurs and proximad of the same the dorsal margins are 

 regularly serrato-spinulose ; external distal spurs three in number, decreasing 

 in length ventrad, the dorsal one one-third as long as the metatarsus, the 

 median one two-thirds the length of the dorsal one, the ventral one hardly one- 

 half the length of the median one; distal spurs of the internal face of the tibiae 

 three in number, decreasing in length ventrad, the dorsal spur equal to one- 

 half the metatarsal length, median spur four-fifths as long as the dorsal spur, 

 ventral spur short, but two-fifths as long as the median one: caudal tarsi 

 elongate, equal to one-half the length of the caudal tibiae; metatarsi occupying 

 two-thirds of the tarsal length, compressed, weakly arcuate dorsad, dorsal mar- 

 gins with seven to eight external and two to four internal spines, external 

 distal spur straight, faintly longer than the second tarsal joint, internal distal 

 spur half again as long as the external one; second tarsal joint short, com- 

 pressed; third tarsal joint elongate, compressed, faintly arcuate; claws very 

 elongate, slender, falcate.

Differing from the description of the male in the following features. Pro- 

 notum faintly less transverse than in the male, greatest length contained one 

 and one-half times in the greatest width of the entire pronotum. Tcgmina and 

 wings absent. Ovipositor slightly shorter tlian the caudal femora, very slender, 

 straight, subequal in depth except for slightly expanding proximad, distal 

 valves not strongly differentiated from the shaft of the ovipositor valves, more 

 compressed, when seen from the side acute lanceolate, no deeper than the 

 shaft, external face multistriate: subgenital plate relatively shorter, compressed, 

 subrostrate, median incision relatively deep, lateral sections of the margin 

 gently arcuate. Cephalic femora slightly less than twice as long as the pronotal 

 disk. Caudal femora equal in length to the body exclusive of the ovipositor: 

 caudal metatarsi with one to no internal and four external spines. 



General color liver brown to kai.ser brown and warm l)ufT, palest on the 

 tibiae, the cephalic and median femora infuscate to a variable degree with 

 mummy brown distad. Eyes bister. Tegmina of male russet. Female with 

 body discolored.
