not a third as long as the tibial spurs, the inner carina with a series of 

 rather distant short spinules partially biseriate, the intervening sulcus 

 broad, equal, and deep. Hind tibiae rather feebly and broadly sinuate 

 (this point is exaggerated in the original figure), a very little longer 

 than the femora, armed beneath with a single long preapical spine 

 besides the apical pair ; spurs subalternate, the basal beyond the end 

 of the proximal third of the tibia, nearly twice as long as the tibial 

 depth, set at an angle of about 35 with the tibia and divaricating 

 about 80, their apical third or fourth considerably incurved ; inner 

 middle calcaria considerably longer than the outer, fully twice as long 

 as the others or as the spurs, but somewhat shorter than the first tarsal 

 joint. Hind tarsi about two fifths as long as the tibiae, the first joint 

 as long as the rest together, the second and fourth subequal, and each 

 about twice as long as the third. Cerci rather stout, tapering regu- 

 larly, about as long as the femoral breadth. 



Length of body, 14.5 mm. ; antennae, 31+ mm. ; pronotum, 4.4 mm. ; 

 fore femora, 6 mm. ; hind femora, 13 mm. ; hind tibiae, 13.5 mm.
