Black orpitchy-black, smooth and shining above and beneath,, 

 with the head and pronotum opaque ; rather narrowly elongate. 

 The head is broad, flat, smooth, with a few well-marked 

 punctures behind the e3^e on each side. The eyes are very 

 small ; the sides of the head are a little swollen behmd the eyes 

 and the anterior part of the head is uniformly curved at the 

 side, gently reflexed and united with the posterior lobe, widely 

 separatmg the eye from the outer margin. The mandibles are 

 broad at the base, strongly bent before the middle, nearly 

 straight externally to the tip and a little dilated internally, 

 and the extremit}^ is bilobed, the outer lobe sharply-pointed 

 and the inner lobe shorter and ])lunter. The pronotum is short 

 and broad, smooth and unpunctured, with the front angles 

 produced but not very sharj), the sides gently rounded, very 

 obtusely angulate beyond the middle and rounded to the base, 

 without trace of hind angles. The scutellum. is small and rather 

 narrow. The elytra are narrower than the head or pronotum, 

 rather parallel-sided, with very acute humeral angles, and each 

 bears a strongly-impre8se<l sutural stria and three pairs of 

 dorsal strife, the first pair feebler than the others and all 

 minutely ])unctured. The sides and apices are strongly and 

 densely punctured. The front tibia is moderately long and 

 bears nimute irregular teeth externally. The middle and lund 

 tibiae are rather flat, not at all slender, without lateral spines 

 but fringed with very short close setae.
