spines, one before the middle of the distal half longer than the others 

 and nearly as long as the tibial spurs, stout at base only (^) or 

 minutely and distantly denticulate in the distal half (9), the inner 

 carina with a similar number of small subequal and subequidistant 

 spines (^), or as in the male (9)> the intervening sulcus narrow and 

 deep. Hind tibiae slender and straight in both sexes, scarcely longer 

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

 the apical pair ; spurs generally opposite, the basal at about the end of 

 the proximal third of the tibia, fully half as long again as the tibial 

 depth, set at an angle of about 50° with the tibia and divaricating 

 about 140° with each other, their tips incurved ; inner middle calcaria 

 very much longer than the outer, more than twice as long as the others 

 or as the spurs and fully as long as the first tarsal joint. Hind tarsi 

 almost half as long as the tibiaB, the first joint nearly as long as the 

 rest together, the second more than twice the length of the third 

 and with it not so long as the fourth. Cerci tapering throughout 

 equally, a little shorter than the femoral breadth, the tip not very 

 pointed. Ovipositor tapering gently in proximal, equal in distal 

 half, the tip upcurved and produced to a fine point, as long as the 

 fore femora, the teeth and apical hook of inner valves slender, long, 

 and arcuate.

Body glabrous, with a broad mediodorsal stripe of dark rufo-luteous 

 "H the thoracic se2:meuts, bordered very broadly on either side with 

 blackish or blackish fuscous, fading out inferiorly, the lower portion of 

 the sides pallid luteous, more or less impure, the very margin luteo- 

 testaceous ; the abdominal segments obscurely continue these longi- 

 tudinal markings, but the black becomes brownish fuscous and is so 

 dotted with dull luteous as to give a very different appearance, the 

 segments being marked with alternate and frequent short longitudinal
