Black, shining, mandibulse plicate longitudinally, the frontal 

 plication very conspicuous, the impressions in the shape of an acute 

 triangle, three or four longitudinal plicse above the eye ; prothorax 

 smooth, outer sides slightly sinuose near the anterior angle, posterior 

 angle very sharp, lateral part of the base diagonal, carinate, median 

 part hardly produced behind but much recurved, on each side of the 

 post-lateral carinae a very fine granulation ; elytra abruptly truncate 

 at the base, with the humeral carina not much produced, the angular 

 tooth distinct, parallel laterally, convex, finely striate, intervals 

 moderately convex, with a series of minute granules on each side 

 of the striae, but sometimes also with the first five intervals without 

 these granules, the intra-marginal interval not much developed, 

 almost obsolete near the base, outer margin broad and densely 

 granulate, along the base also a dense granulation ; prosternum 

 slightly granulose ; sides of metasternum and of abdomen slightly 

 shagreened; anterior tibiae tri- or quadri-dentate above the digitation. 



This species seems to range from Abyssinia to South Africa. It is 

 in the examples from the first-named country that the small granules 

 on each side of the smooth striae are found. Length 27-28 mm. ; 

 width 8 mm.
