Hab. Amazons. Collected by Mr. Bates. 
Head strongly produced between the eyes, vertex smooth, in- 
distinctly impressed with a longitudinal groove; antennz very 
robust, not increasing in thickness towards their apex, the latter 
acute ; basal joint thickened, second to the sixth inclusive short, 
nearly equal in length, the sixth being scarcely shorter than the 
fifth, obturbinate, seventh nearly equal in length to the fifth 
and sixth, and, together with the four apical joints, opake and 
not stouter than those preceding ; sutural lines between the last 
four entirely obsolete. Thorax not twice as broad as long, 
sides straight at the base, rounded and narrowed in the middle, 
sinuate in front, lateral margin obsoletely denticulate ; above sub- 
cylindrical, flattenedand excavated transversely onthe hinder disk; 
surface impressed with large, round, deep punctures, which are 
crowded on the sides, more distant on the disk; a broad lateral 
vitta on either side, and a narrow stripe down the centre, black ; 
basal lobe broadly truncate, its surface oblique, transversely 
grooved. Scutellum pentagonal, its basal half oblique, the apical 
surface horizontal. Elytra broader than the thorax, nearly pa- 
rallel, slightly increasing in width towards the hinder angles, 
sides narrowly margined, finely toothed, hinder angles produced 
into a broad triangular process, which, ‘slightly dilated laterally, 
does not reach backwards beyond the apical margin, its posterior 
edge armed with three or four large teeth; apical margin of 
elytra furnished with coarser teeth than those on the sides. 
All the thighs armed beneath with an acute tooth.
