This genus contains about fifteen species, which are confined to 

 Europe, Northern Asia, Japan, and North America; it is distinguished 

 f re m At)i(ws\)y having the first tarsal joint shorter, and from Limoniuti 

 by the longer and somewhat spiniform posterior angles of thorax; the 

 tarsal claws are simple, and the antennae are rather short and serrate 

 from the fourth joint; three species are found in Europe. 



S. brunneua, L. (fugax, F.). Oblong, clothed with fine silky 

 pubescence, dull, colour variable; head thickly punctured, antennas 

 rather short, serrate from the fourth joint inclusive, second joint small; 

 thorax rather longer than broad, convex, with thick and shallow 

 umbilical punctures, central furrow more or less distinct, posterior angles 

 strongly projecting and carinate, embracing the shoulders; scutellum 

 large, thickly punctured; elytra rather strongly acuminate towards apex, 

 finely striated, interstices thickly granulate; legs more or less fuscous or
