  Remarks. 
  — 
  This 
  species 
  bears 
  a 
  superficial 
  resemblance 
  to 
  P. 
  stearnsi 
  

   Ives, 
  which 
  is 
  reported 
  from 
  the 
  North 
  Kuriles 
  by 
  Ohshima 
  (1933d), 
  

   but 
  it 
  is 
  readily 
  separated 
  from 
  that 
  species 
  by 
  the 
  peculiar 
  shape 
  of 
  the 
  

   proboscis. 
  Simushiru 
  is 
  one 
  of 
  the 
  islands 
  of 
  the 
  Kurile 
  group.
