Hab. AmazoDs. Collected by Mr. Bates. 



Head strongly produced between the eyes, vertex smooth, in- 

 distinctly impressed with a longitudinal groove ; antennse 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,tlattcnedaud excavated transversely on the 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 aide, and a narrow stripe down the centre, black ; 

 basal lobe broadly truncate, its surface oblique, transversely 

 grooved. Scutcllum 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. 

 Ail the thighs armed beneath with an acute tooth.
