Flavous, with a black triangular patch on the vertex of the head,

 sub-basal small elongate one on each side of the discoidal patch, and 

 three elongate spots on the third, fifth, and seventh intervals of the 

 elytra ; head a little broader than long, clypeus produced at middle 

 in two short recurved teeth, and slightly emarginate on each side of 

 the recurved teeth in the female, while in the male the teeth are 

 slightly less pronounced and a little more diverging, and there is no 

 emargination on each side of them ; in the female there is often a 

 somewhat shallow depression in the middle of the head which is not 

 found in the male, but there is no ridge in either sex except that of 

 the gena:-, which do not project laterally beyond the line of the 

 clypeus ; prothorax sub-parallel but a little attenuate laterally in 

 the anterior part ; the base is straight, the surface plane, slightly 

 aciculate in the centre, but deeply and closely punctured laterally ; 

 scutellum small, smooth; elytra nearly as broad as the prothorax at 

 base, a little attenuate laterally towards the apex, sinuate at some 

 distance from the humeral part, and leaving the edges of the three 

 first abdominal segments very visible ; they are plane, glal^rous 

 except for a fringe of seta) on the apical margin, very distinctly 

 punctato-striate, with the intervals nearly plane on the disk, and the 

 third, fifth, and seventh broader than the others ; under side glabrous, 

 variegated with black ; prosternum without any intercoxal process, 

 median part of metathorax smooth and with a faint median longi- 

 tudinal line, lateral part granulose ; pygidium with two small

 conspicuous sub-horizontal ridge in the male.
