Vertex and front opaque, the former impressed with an ill-defined fovea ; interocular 
space moderately produced, obtuse. Antenne less than one third the length of the 
body, thickened towards the apex ; joints cylindrical, the apex of the club acute. Thorax 
transverse ; sides straight and parallel from the base to the middle, thence rounded and 
converging towards the apex, sinuate anteriorly, the apical angle armed with a strong 
subacute tooth; disc coarsely punctured, a narrow medial line, and the space imme- 
diately behind the apical margin, free from punctures. Elytra subparallel before 
the middle, thence gradually dilated towards the posterior angle, the latter laterally 
produced ; apex obtusely rounded ; lateral margin very finely, the apical one coarsely 
and irregularly, serrulate ; each elytron with ten, at the extreme base with eleven, 
rows of punctures; the second and fourth interspaces strongly costate, subsinuate, 
the eighth interspace very slightly thickened; humeral callus laterally produced, its 
apex obtuse.

punctato, margine laterali, nec non plagis discoidalibus duabus, a basi ad apicem extensis, interdum ante 
apicem abbreviatis, nigris ; elytris oblongis, lateribus ante medium fere parallelis, hinc ad apicem perparum 
ampliatis, minute serrulatis, angulo postico abrupte lateraliter dilatato; apice obtuse truncato, fortiter ser- 
rato; utrisque decem-, basi extrema undecim-seriato-punctatis, interspatiis secundo et quarto valde costatis
