Head perpendicular, face a little ele\ated ; pronotum with the 

 lateral angles more or less produced, the processes three-cornered 

 or tricariuate ; the posterior process long, narrow, broad at base, 

 beneath posteriorly compressed and amplified and reaching or 

 passing the posterior angle of the interior margin of the tegmina, 

 this process is also three-cornered or tricarinate ; sides of the pro- 

 and mesosterna armed «ith a small lobe or tooth ; wings with three 

 apical areas ; tibiiB compressed and moderatelj" dilated. 



I have inch;ded I'olocenirus, Biickt. as a synonym of O.n/rhachis, 

 because its describer states that P. rufus " may be taken as 

 typifying the genus," though the first species he enumerates 

 (-P. latijyes) evidently belongs to the genus XijJiisies.
