ally. It, however, difl^rs in its femora dentate beneath, its 

 more slender rostrum, its prothorax wider with more rounded 

 sides and closer sculi)ture , its elytra slightly protuberant belnnd 

 the scutellum, its less linear form, and its abdomen with the 

 pilosity of the middle part (though forming a similar pattern) 

 much less dense and conspicuous (this is not owing to abrasion). 

 The fourth joint of the antennae is scarcely longer than the third. 

 Jn some examples the pilosity along the suture scarcely consists 

 of spots, but is continuous.

 This species is remarkably like S. Ilehnsi, but is at once dis- 

 tinguishable from it by the strongly-defined hump behind its 

 scutellum, by the notably closer and less-coarse sculpture of its 

 head and prothorax, by its prothoracic channel almost devoid of 

 pilosity (apparently not the result of abrasion), by the very 

 evidently closer puncturation of its elytra, by the longitudinal 

 concave spaces on the elytra being very feeble (the outer one 

 scarcely traceable), by the third joint of the antennse being not 

 at all longer than the fourth, by the presence of a large round 

 denuded spot on the episterna of the metasternum— that part 

 being in S. Ilelmsi (as in most Beli) covered uniformly with the 

 pilosity of the lateral stripe— and by its shorter hind femora. 



The male is a little smaller and narrower than the female, its 

 rostrum scarcely different from that of the female, its elytra a 

 little less produced posteriorly, and (as usual in the genus) its 

 anterior femora much less incrassate.
