Brownish fiisfous with a ferrugjiiious t ,oe. Head not prominent, 

 hiteo-testaceous with an olivaceous ti'^^d, tieeked feebly with fuscous, 

 above deeply infuscated ; vertex feebly tumiii, scarcely raised above the 

 level of the prouotuni, the interspace between the eyes no wider than 

 the tirst antennal .joint: fastigiuin steeply deciivent, sulcate throughout; 

 frontal costa narrow, no wider '^han the intersi)ace between the eyes, 

 e<[aal. ]>ercurrent, distinctly sulcate excepting above, punctate; eyes 

 large, prominent, much longer than the intraocular portion of the genae; 

 antennae dull luteous at base, growing rufescent beyond, apically infus- 

 cated. about threeiifths as long as the hind femora. Pronotum sub- 

 equal, the disk nearly plane but very broadly tectate, passing by an 

 abrupt angle, forming a distinct lateral carina, into the slightly tumid, 

 subvertical lateral lobes, which are marked above on the ])rozona by an 

 exceptionally broad piceous belt, broader on the anterior than on the 

 posterior section : mediancarinaeciually distinct throughout; front and 

 hind margins truncate, the latter feebly emarginate in the middle; 

 prozona longitudinal, very sparsely punctate, almost twice as lour; as 

 the tinely but obscurely ruguloso punctate metazona. Prosternal spine 

 short, lobate, appressed, /ery blunt, suberect; intersiiace between 

 mesosternal lobes a little longer than broad, the metasternal lobes 

 approximate. Tegmina obovate, well rounded, twice as long: as broad, 

 longer than the head and pronotum together, attingent, uniform dark 

 castaneous. Fore femora feebly tumescent; hind femora rufo luteous, 

 olivaceous on the outer lace, rather broadlv and transverselv bitasciate 

 with fuscous, the whole geniculation blackish; hind tibiae pale, rather 

 dingy greenish, with a lutescent basal annulus the spines black almost 

 or <iuite to the base, ten in number in the outer series. Extremity of 

 male abdomen slightly clavate, a little upturned, the supraanal plate 

 rather long triangular, the lateral margins slightly elevated, a pair of 

 short, distant, apical ridges, and tlie median sulcus rather deep and 

 conspicuous between shar[) and rather high walls extending beyond 

 the ndddle of the plate: furcula consisting of a i)air of slight denticu. 

 lations overlying the bases of the subniedian ridges of the supraanal 

 plate; cerci long and rather slender, tapering in the basal third only, 

 beyond ecpial nearly to the tip, which is riumded but une([ually curved, 

 forming a blunt angle interiorly, the whole fully four times as long as 

 the median breadth, yet scarcely Surpassing the tip of the supraanal 

 pl:\te, gently incurved apically, the whole lower margin straight; sub- 

 genital plate small, considerably longer than broad, broader at base 

 than at apex, the apical margin neither elevated nor prolonged, well 

 rounded but feebly angulate, entire.
