front carina, and on the hind carina 2-3 spines besides a very long 

 genicular spine. Hind femora nearly as long as the body, fully twice 

 as long as the fore femora, stout basally but rapidly tapering so that 

 the apical third or more is subequal, nearly four times as long as 

 broad, with no raised points, both carinas distantly and finely serrulate 

 in the apical half, a little finer and more distant in the female than in 

 the male, the intervening sulcus not very broad. Hind tibiae straight 

 in both sexes, fully a sixth longer than the femora, armed beneath 

 usually with two subapical spines besides the apical pair ; spurs sub- 

 alternate, the basal a little beyond the proximal fourth of the tibia, 

 nearly three times as long as the tibial depth, set at an angle of about 

 50 with the tibia and divaricating 110-130, their tips considerably 

 incurved ; inner middle calcaria a good deal longer than the outer, 

 fully twice as long as the others or as the spurs, but shorter than 

 the first joint of the tarsi. Hind tarsi more than two fifths the length 

 of the tibiae, the first joint as long as the rest together, the second 

 three times as long as the third and as long as the fourth. Cerci 

 very long and slender, but shorter than the fore femora. Ovipositor 

 two thirds as long as the hind femora, very feebly arcuate, rather 

 slender, tapering gently throughout, a little upturned and very acutely 

 pointed at tip, the apical teeth of the inner valves delicate and finely 

 pointed, but not very long, especially the proximal.

Dark fuscous feebly marked, at least on the pronotum, with cloudy 

 dull luteous vermiculations, especially on the lower part of the descend- 

 ing lobes, which are generally edged more distinctly with luteous ; 

 legs of the color of the body or lighter, the anterior pairs more or 

 less infuscated near the femoro-tibial articulation, the distal part of the 

 tibiae and tarsi more clearly luteous ; hind femora with the usual 

 markings, growing luteous toward the base. The antennas are slender
