veins mostly fuscous. Fore and middle femora a little tumid in the 

 male ; hind femora luteo-testaeeous, outside (excepting below) more or 

 less deeply iufuscated, the infuscation sometimes confined to, or more 

 marked in, very oblique dusky fasciations, which also cross the upper 

 face, the lower face generally dull orange; hind tibiae very variable 

 but generally nearly uniform in color, pale red or glaucous being the 

 prevailing color, but they are sometimes plumbeous or yellowish; 

 spines black tipped, ten to twelve, usually eleven, in number in the 

 outer series. Extremity of male abdomen clavate, feebly recurved, the 

 supraanal plate triangular with aeutangulate apex, the surface nearly 

 flat with a narrowing, moderately deep, median sulcus between rather 

 prominent ridges, which are confluent apically and terminate a little 

 beyond the middle of the plate; furcula consisting of a pair of rather 

 distant, parallel, slender spines, somewhat longer than the last dorsal 

 segment, overlying the ridges of the supraanal plate; cerci with the 

 basal portion stout, rectangular, not very strongly compressed, nearly 

 twice as long as broad, the apical portion of the same shape but broadly 

 rounded at the tip, nearly as long as the basal part, but narrower, bent 

 from it upward at an angle of 45, bent also inward, much compressed 

 and shallowly sulcate, with an inferior bounding ridge; subgenital 

 plate very short, subequal but apically rounded, the lateral margin 

 somewhat infolded at base, the apical margin mesially angulate, thick- 

 ened and feebly tuberculate.
