pieeous band; vertex somewhat tumid, barely elevated above the 

 pronotuin, the interspace between the eyes nearly (male) or much 

 more than (female) twice as broad as the first antenna! joint; fastig- 

 ium distinctly sulcate, with elevated rounded margins; frontal costa 

 fading just before the clypeus at least in the male, slightly narrowed 

 above, as broad as the interspace between the eyes (or barely nar- 

 rower in the female), slightly sulcate excepting above, punctate 

 throughout; eyes of moderate size, slightly prominent in the male, 

 barely longer (male) or barely shorter (female) than the infraocular 

 portion of the geuae; antennae rufous, sometimes a little infuscated 

 apically, two-thirds (male) or less than three-fifths (female) as long- 

 as the hind femora. Pronotum slightly (male) or distinctly (female) 

 enlarging from in front posteriorly, the disk rounded subtectiform, 

 passing by a distinct but rounded angle into the gently tumid sub- 

 vertical lateral lobes, often with feeble subflavous lateral stripes next 

 the lateral carinae, the upper half of the lateral lobes of the prozona 

 occupied by a more or less distinct blackish (sometimes pieeous) belt, 

 sometimes followed below by luteous flecks; median carina percurrent 

 but less distinct on the prozona than on the metazona, generally sub- 

 obsolete between the sulci in the male; front margin faintly convex, 

 hind margin very broadly obtusangulate, sometimes rotundato-obtus- 

 angulate; prozoua distinctly longitudinal (male) or faintly longitudinal 

 or quadrate (female), fully a third (male) or but little (female) longer 

 than the finely punctate metazona. Prosternal spine moderately long, 

 appressed conical, rather bluntly pointed, a little retrorse; interspace 

 between mesosternal lobes from half as long again as broad to twice 

 as broad with divergent sides (male) or transverse but much narrower 

 than the lobes (female), the metasternal lobes subattingent (male) or 

 approximate (female). Tegmina ovate lanceolate, apically acuminate, 

 overlapping, somewhat longer than the pronotum, brownish fuscous, 

 generally with a narrow median line of alternating blackish and flavous 

 dots or' dashes; wings pale flavous, sublinear, aborted. Fore and 

 middle femora considerably tumid in the male; hind femora testaceous, 

 more or less suffused either with ferruginous or olivaceous, the outer 

 face often iufuscated, especially in the upper half, the upper face and 

 especially its inner half bimaculate with blackish fuscous, which some- 

 times invades the flavo-testaceous inner face, the lower face more or 

 less rufous or ferruginous, the geiiicular arc pieeous; hind tibiae glau- 

 cous, the spines pallid at base, black a-pically, nine to twelve (usually 

 ten) in number in the outer series. Extremity of male abdomen 

 clavate but apically conical, much recurved, the supraanal plate tri- 

 angular, with feebly convex sides, bluntly acutangulate apex, and 

 surface nearly plane except for the rather high, percurrent but apic- 

 ally obsolescent, submedian ridges bounding the moderately narrow 

 median sulcus; furcula consisting of a pair of small and short, sub- 

 parallel, tapering, pointed fingers or spines lying on the outer side of
