 compact, well punctured iDut moderately shining. The 

 clypeus is bluntly acuminate, and not distinctly bifid. The 

 mandibles are rather broad and leaf-like, strongly incurved 

 at the sides and not straight as usual. The maxillary 

 lobe is slender and without teeth. 



$. The head is armed with a compressed horn, not very 

 long or slender, with its anterior face slightly dilated and 

 the posterior part rather compressed, and bearing a tooth 

 beyond the middle except in poorly-developed specimens. 

 The prothorax bears a stout and sharply-pointed but not 

 very long horizontal horn on each side of its dorsal part, 

 and the median and posterior part is smooth and the sides 

 rugosely punctured. 



^. The head bears a slight sharp tubercle and the 

 prothorax is feebly channelled along the middle where, as 

 well as at the front and sides, it is rugosely punctured.
