  Loman's 
  description 
  of 
  this 
  species, 
  based 
  on 
  an 
  immature 
  specimen, 
  

   is 
  inadequate. 
  The 
  oviger 
  is 
  9-jointed 
  instead 
  of 
  8-jointed 
  and 
  the 
  

   legs 
  are 
  much 
  shorter 
  and 
  thicker 
  than 
  indicated 
  in 
  his 
  figure. 
  The 
  

   proboscis 
  is 
  somewhat 
  variable. 
  In 
  the 
  specimen 
  I 
  have 
  chosen 
  for 
  

   illustration 
  it 
  is 
  barrel 
  shaped, 
  as 
  in 
  Loman's 
  figure. 
  The 
  abdomen 
  is 
  

   squarish 
  at 
  the 
  tip. 
  P. 
  ungellatum 
  is 
  apparently 
  related 
  to 
  P. 
  steamsi 
  

   Ives, 
  but 
  it 
  is 
  without 
  the 
  dorsal 
  trunk 
  tubercles 
  of 
  that 
  species. 
  The 
  

   genital 
  pores 
  are 
  on 
  the 
  ventral 
  surface 
  of 
  the 
  last 
  two 
  pairs 
  of 
  coxae.

  Although 
  this 
  species 
  is 
  described 
  from 
  specimens 
  collected 
  from 
  

   Okinawa 
  and 
  is 
  not 
  represented 
  in 
  any 
  collections 
  available 
  to 
  me, 
  it 
  

   seems 
  appropriate 
  to 
  publish 
  a 
  translation 
  of 
  the 
  Japanese 
  description, 
  

   which 
  is 
  unaccompanied 
  by 
  any 
  figures 
  or 
  synopsis 
  in 
  a 
  European 
  

   language. 
  While 
  a 
  figure 
  has 
  been 
  published 
  in 
  the 
  "Illustrated 
  En- 
  

   cyclopedia 
  of 
  the 
  Fauna 
  of 
  Japan," 
  this 
  work 
  is 
  not 
  generally 
  avail- 
  

   able, 
  and 
  I 
  am 
  able 
  to 
  provide 
  figures 
  from 
  Professor 
  Ohshima's 
  notes. 
  

   The 
  description 
  that 
  follows 
  is 
  based 
  on 
  a 
  literal 
  translation 
  pre- 
  

   pared 
  by 
  Dr. 
  Masui 
  Kodani, 
  together 
  with 
  notes 
  supplied 
  by 
  Professor 
  

   Ohshima, 
  and 
  I 
  wish 
  to 
  thank 
  Dr. 
  Kodani 
  for 
  his 
  generous 
  assistance 
  

   in 
  this 
  and 
  several 
  other 
  details 
  connected 
  with 
  the 
  Japanese 
  language. 
  

   I 
  am 
  especially 
  indebted 
  to 
  Professor 
  Ohshima 
  for 
  supplying 
  the 
  ad- 
  

   ditional 
  notes 
  and 
  drawings. 
  Items 
  in 
  brackets 
  are 
  my 
  own 
  comments 
  

   and 
  additions.
