coarse at the base, taper very gradually, and are of immense length, 

 being more than four times the length of the body. The legs are 

 very long and slender. Fore femora scarcely broader than middle 

 femora, very slender, three fourths as long again as the pronotum, yet 

 only about half as long as the hind femora, the inner carina armed 

 with 2-5 spines. Middle femora with 2-5 spines on the front cariua 

 and on the hinder 1-3 spines besides a not very long genicular spine. 

 Hind femora about as long as the body and twice the length of 

 the fore femora, not very stout, about four times as long as broad, 

 tapering gracefully, the apical third being subequal, the darker por- 

 tions covered with exceedingly fine and subdued raised points, the 

 outer carina with more or less slight distant serrations or triangular 

 denticulations occasionally developing as spines, especially on the 

 apical half, the inner carina with a few slighter distant similar serra- 

 tions closest in the middle half, the intervening sulcus not very broad. 

 Hind tibiae slender, straight in both sexes, fully a tenth longer than 

 the femora, armed beneath with 2-3 subapical spines besides the apical 

 pair; spurs vaguely opposite or subopposite, the basal within the 

 proximal fourth of the tibia, about half as long again as the tibial 

 depth, set at an angle of about 40 with the tibia and divaricating 

 about 90, their tips much incurved ; inner middle calcaria much 

 longer than the outer, more than twice as long as the others or as the 

 spurs and as long as the first joint of the tarsus, beset with short hairs, 

 as are also the upper calcaria. Hind tarsi fully two fifths the length 

 of the tibia, the first joint shorter than the rest combined, the second 

 twice as long as the third and with it shorter than the fourth. Cerci 

 rather long and slender, tapering to a fine point, fully half as long as 

 the hind femora. Ovipositor three fifths the length of the hind femora, 

 not greatly swollen at base, tapering gently in basal half, equal beyond 

 and not very narrow, the tip scarcely upturned and not produced, the 

 apex being nearly rectangular, the teeth of the inner valves feebly 

 crenate.
