declivent, distinctly (cJ*) or scarcely (9) sulcate; frontal costa fading 

 far before the clypeus, subequal, fully as wide as the interspace be- 

 tween the eyes, depressed at the ocellus, punctate throughout ; eyes, 

 especially in the male, rather large and somewhat prominent, very 

 much longer than the infraocular portion of the genae ; antennae luteo- 

 testaceous, sometimes castaneous, luteous toward the base, in both 

 sexes about half as long as the hind femora. Pronotum subequal, 

 short, in the female expanding a little on the metazona, the disk vary- 

 ing from fusco- testaceous to dark fuscous, edged laterally with pale 

 testaceous, at least on the prozona, the lateral lobes with a more or 

 less distinct, glistening fuscous, postocular band on the prozona, on the 

 metazona becoming plain fuscous, sometimes in the female tinged with 

 ferruginous, the lobes below pallid testaceous more or less dotted with 

 fuscous or infuscated, and narrowly edged throughout with pallid tes- 

 taceous; disk nearly plane, passing by a rounded shoulder, in the fe- 

 male forming faint blunt lateral carinae, into the subvertical lateral 

 lobes ; median carina moderately distinct and coarse, subobsolete be- 

 tween the sulci; front and hind margins almost truncate; prozona 

 feebly arched longitudinally, longitudinal, about a fourth or a fifth (c^) 

 or a third (9) longer than the rather heavily punctate metazona. 

 Prosternal spine rather small, erect, conical, not very bluntly acumi- 

 nate; interspace between mesosternal lobes more than twice (cf*) or 

 less than half (?) as long again as broad, the metasternal lobes at- 

 tingent (cJ*) or approximate (?). Pleura piceous or fuscous with a 

 pale flavous oblique stripe. Tegmina a little shorter than the prono- 

 tum, attingent or slightly overlapping, broad ovate, hardly angulate 

 apically, much less than twice as long as broad, fusco-testaceous. Fore 

 and middle femora somewhat tumid in the male, pale olivaceo-testa- 

 ceous flecked with fuscous ; hind femora rather slender, pale testaceous, 

 confusedly trifasciate externally with blackish fuscous, pale orange be- 

 neath, the genicular arc fuscous; hind tibiae blue, a little paler next 

 the base and along the spiniferous margins (or at least the external 

 one), the spines pallid on basal, fuscous on apical half, 9-10 in number 

 in the outer series. Abdomen strongly carinate, pale testaceous, flav- 

 escent beneath, the sides more or less belted with piceous, the extrem- 

 ity in the male clavate, a little upturned, the supraanal plate triangular, 

 acutangulate, nearly plane except for the somewhat prominent and 

 sharp ridges which bound the percurrent median sulcus, and which 

 suddenly divaricate basally; furcula consisting of a pair of hardly
