Type, P. reversa, Hope (^Euryhrachis) . 



I was unable [supra] to properly describe this genus, as I 

 only knew it then by Hope^s figure. 



Head broad, but including eyes not reaching the anterior 

 angles of the pronotum, vertex with the margins prominently 

 ridged, eyes distinctly spined; face with the lateral margins 

 obliquely directed outwardly to about middle and then more 

 acutely directed obliquely inwardly to base of clypeus, which 

 is as long as face ; rostrum about reaching the posterior 

 coxae ; pronotum a little longer than vertex, its lateral 

 margins subacutely produced ; mesonotum longer than pro- 

 notum, with a distinct central ridge not quite reachino- either 

 anterior margin or apex ; femora moderately flattened and 

 dilated, anterior and intermediate tibise outwardly laminately 

 dilated, the former more strongly so, posterior tibiae with five 

 spines; tegmina of moderate length, widened from base to 

 apex, apical margin obliquely rounded, venation reticulate 

 throughout; wings long, about as long as tegmina, but 

 obliquely lobately posteriorly produced, apical margin 

 rounded, posterior margin sinuate.
