one or two others. Middle femora with the front carina armed as in the 

 fore femora, the hind carina the same but the apical spine genicular and 

 very long. Hind femora broad but not heavy, scarcely more tLan three 

 times as long as broad, tapering rather rapidly so that the distal fourth is 

 subt'qual. considerably more than twice as long as the fore femora, with 

 half a dozen raised points on the upper surface beyond the middle, the 

 outer carina with tour or five serrations next the narrowest portion of 

 the femora and before it half a dozen widely separated inequidistaut 

 spines, of which two or three just beyond the middle of the femora 

 are larger than the others and rather coarse, the longest no longer 

 than the tibial spurs (J*) or wholly unarmed except for two or three 

 inconspicuous pregenicular spinules (9), the inner carina with a series 

 of rather distant slight spinules, slighter and less frequent in the 9 than 

 in the ^, the intervening sulcus moderate. Hind tibiae straight in 

 both sexes or with the faintest possible arcuation in the ^, distinctly 

 though not greatly longer than the femora, armed beneath with a 

 single preapical spine, besides the apical pair; spurs subalternate, 

 the basal placed before the end of the proximal fourth of the tibia, 

 nearly or quite twice as long as the tibial depth, set at an angle 

 of about 50° with the tibia and divaricating about 110'^, their tips 

 feebly incurved ; inner middle calcaria but little longer than the 

 outer, considerably more than twice as long as the others, nearly 

 twice as long as the spurs, and slightly longer than the first tarsal 

 joint. Hind tarsi two fifths the length of the tibiae, the first joint 

 about as long as the rest together, the second twice as long as the 

 third and with it about the length of the fourth. Cerci rather stout 

 at base, tapering beyond, not so long as the femoral breadth. Ovi- 

 positor more than three fifths the length of the hind femora, straight, 

 tapering on proximal half or less, beyond moderately slender, the tip 

 upturned and produced to an extremely acute point, the teeth of the 

 inner valves aculeate and more or less arcuate. 



Length of liody, ^ 13.5 mm., 9 13 mm.; pronotum, ^ 4.3 mm., 

 9 5 mm.; fore femora, ^ 9 5.5 mm.; hind femora, (^ 12.25 mm., 

 9 12.5 mm. ; hind tibisE, ^ 14 mm., 9 13 mm. ; ovipositor, 8 mm.
