The colour, which is very brilliant, appears not to be reflected from the surface, but seems as if covered with a fine transparent {58}varnish. Head quadrangular, margined and furrowed. Thorax smooth and finely polished. Scutellum large and triangular. Elytra slightly striated, with punctures, and margined. Sternum long and slender. Tibiæ with two spurs. This species, according to Mr. Smeathman, frequents flowers; thus resembling in its habits the British species of the family to which it belongs.
