Nigrum, nitidissimum, antennis, clava excepta, femoribus rufis, tibiis tarsisque rufo-piceis, oculis subdistantibus; prothorace sat dense punctato, antrorsum lateribusque lineatim marginato, ante basin linea transverse arcuata et secunda media ante scutellum longitudinali, antrorsum abbreviata, grosse punctatis, impresso; elytris subtiliter punctatis, stria suturali fortiter impressa, in fundo punctis minutis perspicuuis, linea basali grosse punctatis; pygidium, propygidium subtusque fere laevis. — Long. 3,3 mm. Entirely black and very shining; the antennae except the club, and the femora rusty-red, the tibiae and tarsi dark brown; upper surface finely although very distinctly and rather densely punctured; under surface with hardly any punctures. The antennae short, the club clearly defined and of the usual shape. The eyes tolerably distant from each other. In most oriental species they are quite close to each other on the fore-head. The thorax but little broader than long, considerably narrowed towards the front margin, the sides and the front margin provided with a distinct marginal line; the usual curved, coarsely punctured line before the hind margin; moreover with a rudimental longitudinal line in front of the scutellum. The elytra punctured in the same manner as the thorax, the deeply impressed sutural line with minute punctures on the bottom and strongly curved at the base; the upper surface of the two apical segments of the abdomen with hardly any punctures.
