The species is distinguished from its nearest ally, S. stri- 

 atocollis, at first sight by its elongate-oblong and unicolo- 

 rous elytra; but it differs in the narrower and much more 

 convex lateral and apical interstices and in the wider and 

 deeper marginal groove of the thorax. In the anterior tarsi 

 of the 9 t ue 1st and 2nd joints have their inner apices 

 sharply produced but scarcely spiniform and the external 

 edge of the anterior tibiae is unarmed in both sexes though 

 having a few short spines on their lower surface.
