(^. Chestnut-red, smooth, shining and impunctured, with the 

 head, mandibles and pronotum dark browai, the head opaque. 

 The body is rather elongate and the legs are slender. The eyes 

 are small, the head has a rather sharj) angle before the eye and 

 is gently and evenly narrowed behind. The clypeal process is 

 short and broad, with a mmute tooth in the middle. The 

 mandibles of the unique specimen are about twice the length of 

 the head, gently curved and a little flattened. They bear a 

 sharp but not long internal tooth beyond the middle, followed 

 immediately by two similar but smaller teeth. The sides of the 

 pronotum are microscopically coriaceous and opaque, the front 

 angles are rather narrowly produced, the lateral margin has a 

 slight angulation before the middle and a strong spiniform 

 tooth beyond it and is strongly concave from the latter to the 

 well-marked basal angle. The elytra are very smooth and 

 shining, but bear extremely minute scattered granules, which 

 are rather closer at the sides. The shoulders are sharp. The 

 mentum is short and rather finely rugose. The prosternnm is 

 rather broad and blunt, but a little produced behind. The 

 metasternum and nhdoinen are clothed at the sides with pale 

 pubescence. The terminal fork of the front tibia is composed 

 of two very short prongs, each with a small tooth at the base, 

 and the lateral teeth are minute. The middle tibia bears a 

 small lateral spine and the hind tibia has none.
