 confideration, joined to that of the antenns in 

 feveral of the Linnsean ft lphse, appearing rather 

 to be perforated, than growing regularly thicker 

 towards their extremity, probably induced him 

 to refer fuch filpha? to this genus ^ thefe infefts, 

 however, differ much more effentially from the

 perfectly refemble in their external appearance, 

 in the flatnefs, breadth, and margin of their 

 elytra, and the appendix or knob at the bafe of 

 their hinder thighs, found upon all the Silphse,
