  This 
  genus, 
  with 
  P. 
  mandibukiHs 
  Cameron 
  as 
  its 
  only 
  included 
  

   species, 
  is 
  unknown 
  to 
  me 
  except 
  by 
  Cameron's 
  description 
  and 
  

   figures. 
  It 
  is 
  apparently 
  related 
  to 
  Acerocephala 
  but 
  differs, 
  

   according 
  to 
  the 
  description, 
  by 
  having 
  the 
  mandibles 
  three- 
  

   fourths 
  as 
  long 
  as 
  the 
  head 
  and 
  bidentate 
  at 
  apex,
