interspace between the eyes rather broad, as broad as (male) or broader 

 than (female) the first anteunal joint; fastigium rapidly descending 

 with a regular curve, broadly and very shallowly sulcate (male) or 

 plane with feebly raised margins between the eyes (female); frontal 

 costa broad, as broad as the interspace between the eyes, equal, or 

 feebly narrower above than below, just failing to reach the clypeal mar- 

 gin, feebly impressed at and sometimes a little below the ocellus, punc- 

 tate especially at the sides; eyes moderate, as long as the infraocular 

 portion of the genae, not very prominent; antennae varying from fulvo- 

 testaceous to rufous, much infuscated apically, about three-fourths as 

 long as the hind femora, nearly as long in the female as in the male. 

 Pronotum with the front margin transverse, the hind margin obtusely 

 angulate, the angle rounded, the median carina percurrent, but feeble 

 on the prozona, the prozona plano-convex, passing by a well-rounded 

 angle into the sub vertical lateral lobes, the disk smooth, quadrate 

 (male) or feebly transverse (female), slightly longer than the finely and 

 densely punctate metazona, the transverse sulci distinct and continuous; 

 the upper two-fifths of the lateral lobes are marked on the prozona by 

 a fuscous or piceous patch, while the lower half is occasionally lighter 

 than the rest of the body. Prosternal spine erect, and moderately long, 

 appressed conical, the tip blunt (male) or short, stout, conico-cylin- 

 drical, very blunt (female); interspace between mesosternal lobes more 

 than twice as long as broad (male) or subquadrate (female) ; inetasternal 

 lobes attingent (male) or distant by half the width of the frontal costa 

 (female). Tegmina r< aching and generally somewhat surpassing the 

 tips of the hind femora, somewhat but rather delicately maculate in the 

 basal two-thirds of the discoidal area; wings pellucid, rather broad. 

 Hind femora fusco-fci ruginous, obliquely blotched externally and above 

 with luteo-testaceous, the lighter parts occurring before and past the 

 middle and as a pregenicular annulus; beneath dull luteous with a 

 tinge of fulvous; genicular arc fusco-piceous; inferior genicular lobe 

 pallid or sordid luteous with a basal black bar; hind tibiae pale red, 

 sometimes with a pale greenish yellow tinge, sometimes with a feeble 

 fuscous patellar mark, the spines black excepting at base, ten to twelve, 

 usually eleven, in number in the outer series. Extremity of the male 

 abdomen a little clavate, much upturned, the supraanal plate rather 

 narrow, demi-oval, with rounded sides and scarcely angulate apex, the 

 rather deep median sulcus terminating beyond the middle by the con- 

 traction of its rather stout lateral walls, each lateral half of the plate 

 with a short apical ridge in its middle; furcula consisting of a pair of 

 straight, parallel, flattened, rather slender, tapering, pointed, basally 

 attiugent fingers, reaching the middle of the supraaual plate; cerci 

 broad, subequal but mesially contracted, compressed, slightly upcurved 

 and incurved laminae, bluntly rounded apieally, more than twice as 

 long as broad, shorter than the supraanal plate; infracercal plates 

 broad, obliquely truncate apically, scarcely surpassing the supraaiial 

 plate; subgenital plate greatly piolonged and elevated apically, the
