their outer margin slightly thickened or thrown up. The 

 mandibles show, as in obesus Parry '), at the base on the 

 outside a bluut tooth or tubercle which is absent in cor- 

 nutus Macl. and distinctus Parry; the top of the recurved 

 process of the mandibles is faiutly bifid which is not the 

 case in the three allied species. The expansed sides of the 

 head are rounded, but show a small emargination in their 

 anterior half; in cornutus the sides of the head are entire, 

 in distinctus strongly and widely emarginate , forming two 

 distinct acute angles. 



The prothorax is provided with a distinct tubercle in 

 the centre of the anterior margin ; the central fovea is 

 rather small, shallow, and provided with a few large and 

 deep punctures; the punctures on the disk are very fine 

 and sparse, becoming larger and denser set towards the 

 sides; the anterior lateral angles are not emarginate but 

 slightly dilated ; beyond the dilatation the sides are slightly 

 bent inwards , consequently the sides of the prothorax are 

 neither straight nor parallel as in distinctus. The scutel- 

 lum is somewhat broader than in distinctus and likewise 

 provided with a few punctures ; the elytra are somewhat 

 more elongate, but their sculpture quite agrees; they have 

 likewise minutely pointed shoulders. 



The undersurface is strongly and densely punctured , the 

 legs however finer and sparser. The middle- and hind tibiae 

 have each three acute spines about the middle externally.
