infuscated apically, about three-fourths (cT) or two-thirds (?) as long 

 as the hind femora. Pronotum very feebly and gradually enlarging 

 from in front backward, especially in the female, rather dark fuscous 

 or fusco-te^taceoiis, the latter particularly in the female, dull testaceous 

 below the postocular band, the disk gently convex, feebly shouldered ; 

 median carina distinct on the metazona, rather feeble on the prozona ; 

 front margin very faintly convex, hind margin very obtusangulate, the 

 angle rounded ; prozona longitudinally (d^ ) or transversely (?) sub- 

 quadrate, generally about a third longer than the closely punctate met- 

 azona. Prosternal spine moderately large, slightly appressed cylindri- 

 cal, blunt, erect; interspace between mesosternal lobes varying from 

 less than half as long again as broad to more than twice as long as 

 broad (d^) or from distinctly to very transverse but narrower than the 

 lobes (? ), the metasternal lobes attingent (d^) or rather distant (? ). 

 Tegmina about or hardly as long as the pronotum, attingent or in the 

 male often feebly overlapping, broadly ovate, the tip feebly angulate 

 (d^) or rounded (? ), hardly more than half as long again as broad, 

 fuscous or in the female sometimes fusco- testaceous obscurely mottled 

 with fuscous. Fore and middle femora considerably tumid in the 

 male, testaceous more or less infuscated ; hind femora testaceous, 

 heavily angulatobifasciate with fuscous, the geniculation fuscous, the 

 under surface dull flavous; hind tibiae varying from dull glaucous to 

 dull luteous (d*) or red (?), the spines black beyond the base, 10-13, 

 generally 11, in number in the outer series. Extremity of male 

 abdomen strongly clavate, considerably recurved, the supraanal plate 

 clypeate with rather abruptly and considerably elevated margins, the 

 basal half or more subrectangular, the apical portion abruptly con- 

 tracted with strongly concave sides and produced apex, which with 

 its elevated margins is the continuation of the percurrent sharp and 

 deep median sulcus; furcula consisting of a pair of minute pointed 

 teeth lying on either side of the base ot the median sulcus; cerci 

 rather long and not very stout, tapering from the base to the middle 

 and then as gradually ex[)anding to the same width, at the middle 

 from a half to two- thirds as broad as at base and about half as broad 

 as the frontal costa at the ocellus, the apical portion rounded, but 

 unequally, its lower portion being considerably produced but in no 

 way acuminate, the whole gently incurved and nearly reaching the tip 

 of the supraanal plate ; subgenital plate moderate, distinctly flaring, 

 gradually broadening apically, where it is nearly as broad as the length,
