entirely punctured and opaque, especially at the sides. The 

 elytra are finely and closely punctured. The front tibia is 

 straight, slender, and rather narrowly forked at the end. 



Variation of the male. In small specimens the head and 

 pronotum are closely and fairly strongly punctured and the 

 sides of the latter densely and rugosely. The mandibles are 

 shorter tiian the head and the upward curvature is not strong. 

 In fairly large males the mandibles are about as long as the 

 head and strongly bent upwards, with the lower edges meeting 

 except at the base. The punctures of the head and pronotum 

 are fine and not very close.

Deep chocolate -brown, with the greater part of the head and 

 mandibles, the antennae and tarsi black, the femora rather 

 l)right-rc(l. Elongate, very convex and moderately shining 

 above. The club-joints of the antenna are moderately long 

 and the seventh joint almost the same length. The prosternal 

 process strong, com[)ressed and right-angled. 



(j*. The head is broad and fiat, finely and densely granular 

 and opacpie, the canthus rounded in front, extending past the 

 middle of the eye and rather prominent laterally at the end. 

 The front margin is excised and the clypeal process minute, 

 simple and tongue-shaped. The pronotum is finely coriaceous 

 but rather shining, except at the sides, which are densely 

 granular and ojiacpie. The front angles are truncate, the 

 lateral margins roughly serrate and nearly straight to beyond 

 the n\id(i!e, where there is a sharp spine, and concave from there 

 to the hind angles, which are roiuided. The elytra are also 

 coriaceous, moderately shining dorsally and dull at the sides. 

 The mentum is hollowed and the front edge of the submentuni 

 is not sharply carinate nor trilobed. The front tibia is finely 

 serrate externally, with strong sharp lateral teeth, and the 

 middle and hind tibia) have each a strong lateral si)ine.
