  We 
  have 
  examined 
  the 
  type 
  of 
  this 
  species 
  (Mus. 
  Comp. 
  Zool.) 
  and 
  

   possibly 
  we 
  have 
  renamed 
  it 
  in 
  our 
  P. 
  similis. 
  However, 
  the 
  abdo- 
  

   men 
  of 
  type 
  is 
  missing 
  and 
  the 
  genitalia 
  have 
  neither 
  been 
  figured 
  nor 
  

   described 
  ; 
  specific 
  identification 
  thus 
  is 
  impracticable.
