siderably declivent, broadly (cP) or scarcely (9) sulcate; frontal costa 

 percurrent or almost percurrent, equal or faintly narrowed above, 

 scarcely narrower than the interspace between the eyes, scarcely sul- 

 cate below the ocellus, irregularly punctate ; eyes moderately large, a 

 little prominent in the male, somewhat longer than the infraocular 

 portion of the genae; antennae dark castaneous or rufo-castaneous, 

 often infuscated apically, about four-fifths (d^) or about two-thirds 

 ( 9 ) as long as the hind femora. Pronotum very feebly and gradually 

 enlarging from in front backward, fusco-testaceous, rarely rufo-testa- 

 ceous, often heavily and coarsely punctate with fuscous, dull testa- 

 ceous below the postocular stripe, the disk gently convex, passing, on 

 the metazona only and especially in the female, with the feeblest sign 

 of any shoulder into the vertical lateral lobes, which are faintly tumid 

 on the prozona ; median carina low but distinct on the metazona, less 

 distinct on the prozona; front margin truncate, hind margin very 

 obtusangulate; prozona subquadrate or quadrate, a third longer than 

 the heavily punctate metazona. Prosternal spine moderately stout, 

 erect, slightly (cJ*) or distinctly (? ) conical, blunt ( 9 ) or very blunt 

 (cT) ; interspace between mesosternal lobes twice as long as broad (d^) 

 or subquadrate ( 9 ), the metasternal lobes subattingent (d^) or approx- 

 imate (9). Tegmina about as long as the pronotum, overlapping 

 feebly, obovate, subacuminate but rounded, about half as long again as 

 broad, or, in the male, more than that, fusco-testaceous, often dotted 

 obscurely with fuscous. Fore and middle femora considerably tumid 

 in the male, testaceous, more or less infuscated ; hind femora testa- 

 ceous, heavily angulato-bifasciate with fuscous, the geniculation fus- 

 cous, the under surface dull luteo-flavous ; hind tibiae variable, pale 

 glaucous, dull luteous more or less infuscated, or pale dull red (the last 

 in the female only), lutescent basally, sometimps pallid along the spin- 

 iferous margins, pilose, the spines black at tip, pallid at base, lo-ii 

 (d^) or 11-12 (9 ) in number in the outer series. Extremity of male 

 abdomen strongly clavate, considerably recurved, tlie supraanal plate 

 markedly clypeate, the basal half having subparallel but gently con- 

 cave sides, the apical half being triangular with more strongly concave 

 sides and acutangulate tip, all the margins a little elevated, the median 

 sulcus distinct and percurrent between moderate ridges ; furcula con- 

 sisting of a pair of the slightest possible knobs or beads on either side 

 of the base of the median sulcus above mentioned; cerci rather large 

 and heavy, tapering gently toward the middle, which is about as broad
