and closely punctured, narrowed beyond the base, leaving 

 a wide gap between them, dilated, serrate and capable of close 

 contact in the terminal lialf and acute at the tip. The pro- 

 notum is more shining than that of the male, strongly ])unctured 

 at the sides and base, and finely in the dorsal part. The elytra 

 are relatively a little longer than those of the male. The front 

 tibia is rather broad, with very strong lateral teeth. 



1^. The head is very short and broad, finely coriaceous and 

 opaque, with very large punctures at the sides behind the eyes. 

 The front margin is almost straight in the middle, the sides 

 project outwards a little beyond the eye and are feebly angulate 

 behind the eye. The jironotmn is also finely coriaceous and 

 opaque, with the sides coarsely pitted and rugose. The front 

 angles are blunt, the sides nearly straight to far beyond the 

 middle, where they are very bluntly angulate, and almost 

 straight to the base. The elytra are conjointly almost as wide 

 as they are long, very smooth and glossy, with the sides and 

 a})ices closely punctured, and the lateral marguis well rounded. 

 The legs are scarcely longer than those of the female, except the 

 front tibia, which is slightly elongate with sharp lateral teeth. 



Variation of the male. In small males the mandibles are 

 about as long as the head, rather triangular in shape, almost 

 straight externallj^ the terminal half slightly bent upward 

 and closely set internally with fine co-adapted teeth, the basal 

 half bearing on a higher level two larger and ver}' blunt teeth, 

 not meeting those of the opposite side, the closed mandibles 

 .showing a wide basal gap. In larger specimens the gap is larger, 

 a single strong tooth remains beyond the base and the terminal 

 teeth are reduced in number. At a further stage the mandibles 

 are gently curved externally and meet only at the tips, the 

 single tooth is reduced and farther from the base. The, 

 mandibles become longer and the single tooth, still dimmishing, 

 removes nearer to the apex than the base, and finally the 

 mandibles are slender, twice as long as the head, quite devoid 

 of teeth but a little hooked at the tip. The head increases in 

 breadth according to the size of the specimen and is very 

 broad in large examples.
