Body very elongate and parallel-sided, extremely smooth and 

 shining. Clypeus flat and rather narrow, with the sides elevated 

 and the front margin very broadly excised, leaving the angles 

 acutely projecting. Eyes large and prominent. Club of the 

 antenna long. Pronotum flat, with the front angles indistinct, 

 the hind angles rounded aiid the base strongly lobed above the 

 scutellum. Scutellum long, narrow and very acute at the apex, 

 which projects beyond the thoracic lobe. Elytra very smooth, 

 gently sinuated beliind the shoulders. Pygidium short and broad, 

 with a transverse carina producing a ventral face. Mesosternal 

 process forming a short blunt tubercle : the meso-metasternal 

 suture very distinct. Front tibia armed with three sharp teeth,
