sexes, the antennae with the seventh joint a little produced, the 

 prostennnn scarcely compressed and not produced. 



$. Narrow, very smooth but not ver^^ glossy. The head 

 bears very minute scattered punctures, and there is a small 

 depression behind the base of each mandible and a minute 

 posterior median pit. The canthus extends past the middle of 

 the eye but is not very prominent laterally and there is a very 

 small lateral prominence behind the eye. The sides of the 

 pronotum and elytra are microscopically coriaceous and the 

 former are subopaque. The lateral margins of the pronotum 

 are gently rf)unded to the very sharp lateral angles and almost 

 straight to the rounded hind angles. The sides of the elytra 

 are rather straight and parallel, and the shoiilders are sharj). 

 The mentum is coarsely rugose. The m.e.taste:rnum, and abdomen 

 are coriaceous at the sides and smooth in the middle. The 

 front tibia is finely serrate externally, with a few rather larger 

 teeth, and the tip is sharply forked. 



i;^. Very large, rather narrow and parallel-sided, very smooth 

 and shining. The head is short and broad, minutely coriaceous, 

 unpunctured, with a slight longitudinal depression along the 

 middle and convex on each side. The eyes are small but very 

 prominent, the canthus inconspicuous, except in front of the 

 eye, where it is sharply angulate, and the sides are strongly 

 contracted behind the eyes. The clyjieal process is divided by 

 a sutural line from the front, fringed with reddish hair, 

 ])roduced to a point and angulate on each side of the base. 

 The mandibles are long and slender, very smooth, strongly 

 curved at the base and apex. They are vertically compressed 

 at the base, where they bear a very strong, acutely produced 

 process beneath and a corresponding but rather less strong 

 and sharp process above. They are very finely and irregularly 

 toothed at the inner edge, where there is also a fairly strong 

 tooth placed well beyond the middle, and the tip is forked. 

 The 'pronotum is minuteh' coriaceous, the front angles are 

 very blunt, the sides gently excised a little behind the 

 angles and sharply angulate at the front and hind limits of 

 the excision, strongly at the latter point. Tliere is another 

 slight but well-marked angulation much behind the nnddle, 

 and from there the margin is gently rounded to the base. The 

 elytra are entirely glossy, their shoulders very sharply angular 

 and the sides rather straight and ])arallel. The nuMitum is 

 rather rugosely })unctured. The metasternum and abdomen 

 are very smooth and shining. Tl\e legs are fairly slender, the 

 front tibia fecbl}^ toothed laterally, the middle tibia has a 

 sharp lateral spine and the hind tibia has none. 



T luive seen no nuile but the large ty])e-specimen. 



^. Length (with mandibles), 85 mm. : (without man- 

 dibles) 59 mm. : breadth, 25 mm.
