Body very elongate; thorax with a distinct and acuminate basal lobe; elytra denticulate at the apex; 

 antennae with their seventh joint obtrigonal, internally acuminate, evidently wider than the sixth, and 

 forming the commencement of the club. Anterior legs of the male with their tibiae sinuate, much bent 

 inwards and widened at the apex, the widest part inwardly angular and compressed and pubescent. 

 Prosternum with the intercoxal plate nearly flat, widened, and widely emarginate at the apex.

Very elongate and subcylindrical ; varying in size from eleven to twenty-four milli- 

 metres ; of a uniform brassy-green colour. Legs and underside nearly black. Very 

 finely punctured above, and finely alutaceous. Head with scattered punctures, which 

 are thicker and deeper in front ; labrum short but distinct ; from the antennal socket 

 a striola passes close to the orbit, but diverges from the eye behind, and extends hardly 

 so far back as the eye itself. Antennae not so long as the thorax ; the third to the 

 sixth joints elongate and subequal, smooth ; the seventh joint triangular, narrower and 

 less pubescent than the succeeding four, which form a flat club. Thorax elongate, 

 narrowed in front, the basal median lobe acuminate, the surface very finely alutaceous. 

 Elytra widest a little below the shoulder; evenly narrowed to the apex, where they 

 divaricate a little, and are each armed with about seven or eight serrate teeth. Front 

 legs of the male long ; their tibiae sinuous at the base, and below the middle abruptly 

 bent inwards, angularly widened and compressed at the tip; their tarsi with the three 

 basal joints widened and very hairy, these joints in the female narrower and less hairy. 

 In certain males the margin of the elytra is expanded below the middle.
