outer angles of the truncate part, which is then median, are broadly 

 hamate inwardly ; prothorax shaped as in the preceding species, but 

 with the outer angles fitting more against the elytra and hiding thus 

 the greatest part of the mesothoracic epimera which are densely 

 pubescent, covered with deep not closely set punctures bearing each 

 a long, setose black hair ; scutellum not punctate ; elytra plane, only 

 moderately sinuate laterally, indistinctly bi-costulate, and having 

 faintly seriate, minute, black bristle-like hairs ; pygidium glabrous, 

 impunctate and having no white patches ; pectus and legs villose, 

 the villose hairs black ; mesosternal process distinct, and vertical in 

 front. 



Female : More robust than the male, black, with the elytra having 

 a faint reddish tinge, there is no marginal white band on the pro- 

 thorax or on the elytra ; the clypeus is nearly twice as long as the 

 head and is slightly narrower at base than at apex with the outer 

 angles rounded and the anterior part deeply emarginate ; head and 

 clypeus deeply punctate ; antennal club somewhat long, ovate ; pro- 

 thorax sparsely punctate, the punctures setigerous ; elytra plainly 

 ampliated laterally from the median part, indistinctly costulate and 

 punctate ; under side almost glabrous, sternal process short, grooved 

 longitudinally ; anterior tibiae tri-dentate, upper hind spur broadly 

 patelliform, racket -like at apex.

Male : Black, opaque, with the elytra light testaceous yellow ; no 

 white marking on the prothorax, elytra, or pygidium ; head and pro- 

 thorax clothed with a long, moderately dense villose flavescent 

 pubescence ; clypeus slightly more than twice as long as the head, 

 strongly and broadly constricted laterally a little above the median 

 part, with the basal outer angles of the constricted part sharply 

 hamate dentate ; the constricted part which is about one-fourth of the 

 length expands at apex into a triangular process strongly hamate at 

 each end, and from the base of the clypeus to the apex there runs a 

 sharply carinate longitudinal ridge, the ocular canthus is horizontal, 

 but is not sharply acute, both head and clypeus are sub-foveate 

 punctate, but the prothorax and the scutellum are only finely
