 continuous with forehead, longer and parallel-sided, always 

 angular, flat above, more or less emarginate at apex ; scrobes 

 deep, well defined, curved ; antennae moderately long, not 

 very robust, scape generally reaching beyond posterior 

 margin of eyes ; thorax generally very short, sides more or 

 less rounded ; legs moderately long, tarsal claws soldered. 



Strophosomus, Schoenh. 



b. Truncate surface at apex of posterior tibiae with 

 outer margin reflexed, forming a cavity. 



Z, Eostrum rounded at angles, distinctly narrower 

 than head, more or less dilated at apex, scutellum 

 generally distinct. 



1. Tarsal claws free. 



Eostrum distinctly longer than head, flat or slightly 

 convex above, often with central furrow, more or less 

 emarginate and fringed at apex ; scrobes deep, curved, 

 usually reaching eyes ; antennae moderately long, rather 

 robust, scape reaching middle of eyes, elytra scarcely 

 broader at base than thorax, shoulders rectangular or 

 obtuse. Barynottcs, Germ. 



2. Tarsal claws soldered. 



Eostrum scarcely longer than head, a little convex and 

 finely ridged above, truncate and fringed at apex, scrobes 

 superficial or moderately deep, rather wide, curved, ending 

 far from eyes ; antennae rather long, not very robust, scape 

 reaching beyond posterior margin of eyes ; elytra broader 

 at base than thorax, shoulders very obtusely angular or 

 rounded. Liophloeus, Germ. 



IT. Eostrum angular, as broad (or nearly so) as head, 

 parallel-sided or slightly narrowed in front ; scutel- 

 lum very small or absent. 



Eostrum at least as long as head, flat, generally with a 

 fine central ridge, often separated from forehead by a trans- 

 verse furrow, more or less emarginate and fringed at apex,
