equal, almost percurrent, about as wide as the interspace between the 

 eyes, sulcate throughout (d') or below the ocellus (?), biseriately and 

 irregularly punctate throughout ; eyes not very large nor very promi- 

 nent, but distinctly longer than the infraocular portion of the gens ; 

 antennae varying from luteous to castaneous, more or less infuscated 

 apically, about as long (cJ*) as the hind femora. Pronotum fuscous, 

 with a broad, piceous, postocular band on the prozona (below which 

 the lateral lobes, at least on the prozona, approach the color of 

 the under surface, and next which the disk is feebly palles- 

 cent), enlarging feebly and regularly from in front backward, especially 

 in the female; disk feebly convex, passing by a feeble angulation into 

 the subvertical lateral lobes; median carina percurrent, but feebler 

 though uniform on the prozona; front margin truncate, hind margin 

 feebly and roundly angulate; prozona a little longitudinal (c?) or 

 longitudinally subquadrate (?), nearly a third longer than the finely 

 and obscurely punctate metazona. Prosternal spine short, erect, very 

 blunt conico-cylindrical; interspace between mesosternal lobes sub- 

 quadrate (cf) or distinctly transverse (?), the metasternal lobes ap- 

 proximate (cT) or rather distant ($). Tegmina abbreviate, a little 

 shorter than the pronotum, ovate, less than twice as long as broad, 

 attingent (cf) or subattingent (9), dark fuscous or blackish fuscous, 

 the apex rounded angulate. Fore and middle femora somewhat tumid 

 in the male; hind femora blackish fuscous above, the outer face 

 nearly black, with the stripe mentioned, pale orange beneath with a 

 pale, pregenicular semi-annulus on the inner side; hind tibiae blue, 

 the spines black, lo-ii in number in the outer series. Abdomen pale 

 flavous, a little infuscated above and the sides piceous basally, the ex- 

 tremity in the male considerably clavate and considerably recurved, 

 the supraanal plate broad hastate, nearly plane, with acutangulate apex 

 and shallow, rather broad, percurrent median sulcus, margined by low 

 blunt walls; furcula consisting of a pair of slight dentiform projections, 

 slightly divaricating and extending beyond the last dorsal segment by 

 less than its length; cerci moderately stout laminae, tapering gently 

 in the basal half and straight, then equal for a short distance and 

 slightly incurved, and then tapering rapidly and curving strongly in- 

 ward to a terminal hook which just fails to reach the tip of the supra- 

 anal plate ; subgenital plate small, flaring a little, of equal breadth 

 and almost as long as its apical breadth, the lateral and apical mar- 

 gins in the same plane, a little angulated where they meet.
