twice as long as broad; metasternal lobes broadly attingent. Tegmina 

 scarcely longer than the pronotuin, broad lanceolate, acuminate, with 

 strongly convex costal margin, pale testaceous. Fore and middle femora 

 very tumid in the male; hind femora uniform navo-testaceous, with no 

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

 base of the geuiculation, and $ fuscous upper edging to the genicular 

 arc; hind tibiae very pale red or pink, the spines pallid on the basal, 

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

 of male abdomen feebly clavate, scarcely recurved, the supraaual plate 

 triangular, tectate, rising to a pair of high but rounded converging 

 ridges, inclosing between them the deep triangular sulcus, which crosses 

 the basal half of the plate; furcula consisting of a pair of stout and 

 coarse, subparallel, rather distant, subequal, blunt projections, a little 

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

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

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

 equal, 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 well rounded, entire. 



Length of body, male, 19 mm.; tegmina, 6.U5 mm.; hind femora, 

 13.5 mm.

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; 

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

 or longitudinal sulcatiou, 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 slightly (female) or considerably (male) longer 

 than the head and pronotuin 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 geuae. Pronotuin 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- 

 form, the median cariua slight but alike or nearly alike in both, the 

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

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

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