spines, often rather long in old individuals, especially the distal ones. 

 Middle femora with 3-4 spines on either carina, the hind carina 

 with a not very long genicular spine. Hind femora as long as or 

 longer than the body, considerably more than twice the length of the 

 fore femora, very stout at base, but gradually diminishing in stout- 

 ness so that the distal third is slender and subequal and the whole 

 less than three and a half times longer than broad, the surface mostly 

 glabrous, but on the darker portions above beset not very sparsely 

 with feeble raised points, the outer carina with about thirteen distant un- 

 equal rather coarse spines, the longest shorter than the tibial spurs ( $ ) 

 or almost unarmed (9), the inner carina much less elevated than 

 the outer, with equal abortive denticulations numerous in the i^, in- 

 frequent and equidistant in the 9, the intervening sulcus moderately 

 broad. Hind tibiae rather slender, straight or in old male specimens 

 gently subarcuate or slightly waved in the proximal third, nearly a 

 sixth longer than the femora, armed beneath usually with two aligned 

 preapical spines besides the apical pair ; spurs subopposite, the basal 

 pair near end of proximal fourth of tibia, less than half as long 

 again as the tibial depth, set at an angle of about 40° with the tibia 

 and usually divaricating about 60°, but sometimes to as much as 

 twice that, incurved especially at tip; inner middle calcaria much 

 longer than the outer, more than twice as long as the other calcaria, 

 about twice the length of the spurs, but much shorter than the first 

 tarsal joint. Hind tarsi much less than half as long as the tibia, the 

 first not so long as the rest together, the second nearly three times as 

 long as the third and with it fully as long as the fourth. Cerci stout at 

 base, tapering throughout, nearly a third as long as the hind femora. 

 Ovipositor with the basal third rather stout, beyond equal and rather 

 slender, nearly three fourths the length of the hind femora, the arma- 

 ture of inner valves acicular, arcuate, elongate.
