rulate in the anterior part oiil\-, Iniso not carinate, smooth ; elytra 

 hardly narrower behind the sloping humeral angle than the pro- 

 tliorax at its broadest part, attenuate from a short distance of the 

 ])ase towards the apex, plane but slightly gibbose past the middle 

 along the suture, very finely striatic with the intervals plane and 

 filled with very fine, shining, very shghtly raised dots; the outer 

 margin is bi-carinate, and the carinop are set very close to one 

 another, and are very slightly divergent towards the shoulder ; 

 pygidium closely aciculate and slightly shagreened ; legs nearly 

 glabrous, robust, anterior tibial strongly quadri-dentate outwardly 

 and strongly serrate from the base to the digitation and also 

 between the teeth, inflexed and dilated from near the median part 

 to the apex inwardly, and closely and distinctly serrate in the male, 

 but not dilated inwardly, and with the outer teeth longer and sharper 

 in the female, and also more sharply serrate, coxae scarcely punc- 

 tured ; metasternum shghtly punctured on the sides, smooth in

So closely allied to the preceding species that it is difficult to 

 distinguish the one from the other. It is, however, considerably 

 smaller, the antennae are flavous-yellow ; the prothorax is very finely 

 and closely punctured, in the male tlie anterior tibiae are not incurved 

 nor dilated at apex, and the elytra are not as attenuate from the 

 humeral angle towards the apex as they are in S. adamastor.
