Head moderate, ferruginous ; eyes ratber prominent; antenna- long and slender, 

 yellow, witb tlie club dusky, with the sixth joint longer but not broader than 

 the seventh. 



Thorax ratber produced in front, not semicircular, widest at the base, very shining, 

 almost impunctate, sides margined, basal margin verj' deeply sinuated, with 

 the angles broad, acute, and very much produced. 



Sctttellum large, witb the apex rounded. 



Elytra rather short, much attenuated in the males, not broader and scarcely one- 

 half longer than the thorax, with a deep sutural stria, deeply asperate, sides 

 margined, extremities broad and rounded. 



Alidomiii moderately exserted, tiavesceut. 



Legs long and slender, bright yellow. 



/ 'nder parts either castaneous or testaceous. 



This species appears to be truly cosmopolitan. I can find no sculptural 

 difference between the European specimens and those which I have received from 

 South Africa, Japan, Australia, New Zealand, the Atlantic Islands, America, and 

 other places; and it is, I think, doubtful whether S. piihi]n'rtnis, S. palUdulus, and 

 .S'. lattts are not extreme local varieties of this species. But as these exhibit 

 considerable diversity in the form of the body and length of the antenniE, I have 

 separated them from .S'. lateralis.
