or obliquely longitudinal bars of brovvnisli fuscous and dull luteous, 

 the darker parts often also dotted with luteous ; legs luteous, more 

 or less infuscated, especially the hind femora the outer surface 

 of which excepting at base is increasingly fuscous distally and 

 broadly annulate with blackish apically, the surface generally sprinkled 

 with luteous dots, with faintly different depths of color marking a 

 scalariform pattern. The hind tibial spines are distinctly blackish 

 at the base. The antennae are about three times as long as the body, 

 luteous, the joints at first feebly infuscated at the base, afterwards 

 wholly, and then interrupted by luteous for a single joint every few 

 joints irregularly, the legs moderately slender and not very long, the 

 hind tibial spurs distinctly infuscated or blackish at base. Fore 

 femora slightly stouter than the middle femora, considerably less than 

 half as long as the hind femora, nearly a third longer than the pro- 

 notum in the $, though but little longer in the 9, the inner carina 

 armed with 2-3 spines. Middle femora with generally 2-3 spines on 

 the front carina and on the hind carina 1-2 spines besides a moderate 

 genicular spine. Hind femora about as long as the body, at least two 

 and a quarter times longer than the fore femora, the swollen portion 

 very gradually tapering and of unusual length, the whole about three 

 and a quarter (^$) or three and three quarters (9) times as long as 

 broad, the surface with no raised points, both outer and inner carina in 

 both sexes almost unarmed, at most a few feeble spinules being seen 

 near the apex, the intervening sulcus narrow. Hind tibife scarcely or 

 no longer than the femora, straight in both sexes, slender, generally 

 armed beneath with two median subapical spines besides the apical 

 pair ; spurs irregularly opposite, the basal at the end of the proximal 

 third of the tibia, slightly longer than the tibial depth, set at an angle of 

 about 45° with the tibia and divaricating about 1 20°, slightly incurved 

 especially at tip ; 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 tarsal joint. Hind tarsi about two fifths as long as the hind 

 tibios, the first joint as long as the rest together, the second more than 

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

 rather slender, tapering, pointed, about two thirds as long as the 

 femora] breadth. Ovipositor twice as long as the fore femora, and 

 about two thirds as long as the hind femora, straight, gently tapering 

 in the proximal, rather slender and equal in the distal half, the tip 

 upturned and acute but not aculeate, the armature of the inner valves 

 consisting of deep denticulations.
