twice as long aa broad; metastenisil lobes broadly attingent. Tegmiua 

 scarcely longer than the pioiiotuin, broad lauceolate, acuminate, with 

 strongly convex costal margin, [jalc testaceous. Fore and middle femora 

 very tumid in the male; hind femora uniform tiavo-testaccous, with no 

 markings except a feeble and narrow, transverse, fuscous stripe at the 

 base of the geniculation, and a fuscous upper edging to the genicular 

 arc; hind tibiae very i)ale red or pink, the spines pallid on the basal, 

 black on the apieal half, 12 in number in the outer series. Extremity 

 ot niale abdouieii feebly clavate, scarcely recurved, the supraanal plate 

 triangular, tectate, rising to a pair of high but rounch'd converging 

 ri'.lges, inclosing between them thedeei) trianguhir sulcus, which crosses 

 the basal half of the ]>late; furcula consisting of a pair of stout and 

 coarse, subparallel, rather distant, subequal, blunt i)iq)ections, a little 

 longer than broad and than the last dorsal segment; cerci slender, deli- 

 cate, conical, straight, tinely acuminate, about as long as the supraanal 

 plate; subgenital plate rather small, considerably longer than broad, 

 eiinal, terminating in a backward-directed, bluntly rounded tubercle, 

 seated on the middle of the apical portion of the plate, the apical and 

 lateral margins in the same plane, the former w^ell rounded, entire.

Body almost parallel-sided, very little enlarged at the metathorax, 

 more or less but not greatly compressed, more so in the male than in 

 the female. Head not very prominent; vertex usually very narrow 

 between the eyes, with a slight depression or sulcation between; 

 fastigium broadening in front of it, declivent, with a median depression 

 or longitudinal sulcation, sometimes distinct, sometimes obscure, the 

 sides rounded; front straight, somewhat oblique, the frontal costa 

 equal, only slightly contracted at the extreme summit, generally as 

 broad as if not broader than the interval between the eyes, sulcate 

 throughout; antennae sHghtly (female) or considerably (male) longer 

 than the head and pronotum together; eyes slightly prominent, a little 

 more so in the male than in the female, rather long oval, much longer 

 than the infraocular portion of the genae. Pronotum long and slender, 

 the dorsum fully half as long again as broad, the prozona the longer, 

 sometimes half as long again as the metazona, with less distinction in 

 surface and sculpture between them than common, alike broadly tecti- 

 toiin, the median carina slight but alike or nearly alike in both, the 

 descending lateral lobes separated by no angle or ruga; posterior mar- 

 uiii very obtusely angulate, the angle rounded, the border delicately 

 imirgined. Prosterual spine rather long, bluntly conical; meso- and
