  THE 
  rHORID 
  FLIES 
  OF 
  GUAM 
  

  

  By 
  G. 
  E. 
  BoHART 
  

  

  The 
  primary 
  purpose 
  of 
  this 
  paper 
  is 
  to 
  make 
  available 
  the 
  names 
  

   of 
  several 
  species 
  of 
  Phoridae 
  (Diptera) 
  whose 
  biology 
  and 
  life 
  history 
  

   will 
  be 
  di!^cu.ssod 
  in 
  a 
  paper 
  (to 
  be 
  published 
  by 
  the 
  Navy) 
  on 
  the 
  filth- 
  

   inluibiting 
  flics 
  of 
  Guam. 
  In 
  it 
  will 
  :ippear 
  biolog^ical 
  notes 
  and 
  de- 
  

   scriptions 
  and 
  illustrations 
  of 
  the 
  early 
  stages 
  of 
  many 
  of 
  the 
  phorids 
  

   herein 
  described. 
  

  

  Except 
  for 
  those 
  species 
  reared 
  from 
  filthy 
  environments 
  no 
  par- 
  

   ticular 
  effort 
  was 
  made 
  to 
  collect 
  phorids. 
  Consequently, 
  several 
  of 
  

   the 
  species 
  described 
  are 
  represented 
  by 
  unique 
  specimens, 
  and 
  it 
  may 
  

   be 
  inferred 
  that 
  numerous 
  species 
  remain 
  to 
  be 
  discovered 
  on 
  the 
  island. 
  

   Because 
  of 
  the 
  paucity 
  of 
  material 
  I 
  felt 
  it 
  advisable 
  to 
  illustrate 
  the 
  

   species 
  as 
  fully 
  as 
  possible, 
  so 
  that 
  if 
  some 
  of 
  these 
  described 
  as 
  new 
  

   prove 
  to 
  be 
  already 
  named, 
  or 
  if 
  the 
  discovery 
  of 
  many 
  more 
  S|)ecic3 
  

   reduces 
  the 
  value 
  of 
  the 
  key, 
  the 
  figures 
  will 
  still 
  prove 
  useful. 
  In 
  

   most 
  cases, 
  in 
  view 
  of 
  the 
  full 
  illustrations, 
  descriptions 
  have 
  been 
  kept 
  

   at 
  a 
  minimum 
  size. 
  

  

  The 
  lii'ld 
  work 
  in 
  connection 
  with 
  this 
  study 
  was 
  done 
  on 
  Guam 
  at 
  

   the 
  field 
  laboratories 
  of 
  Naval 
  Medical 
  R'search 
  Unit 
  No. 
  2 
  under 
  the 
  

   diifction 
  of 
  Conuiiodore 
  Thomas 
  J. 
  Rivers. 
  The 
  taxonomic 
  work 
  and 
  

   the 
  preparation 
  of 
  the 
  paper 
  were 
  done 
  at 
  the 
  U. 
  S. 
  National 
  Museum 
  

   under 
  the 
  auspices 
  of 
  the 
  Research 
  Division 
  of 
  the 
  Bureau 
  of 
  Medicine 
  

   and 
  Surgery. 
  I 
  am 
  much 
  indebted 
  to 
  Lt. 
  (jg) 
  J. 
  L. 
  Gressitt, 
  who 
  

   worked 
  with 
  mo 
  on 
  Guam, 
  for 
  some 
  of 
  tlic 
  rearing 
  and 
  collecting 
  of 
  

   specimens 
  and 
  for 
  carrying 
  on 
  the 
  work 
  after 
  I 
  left 
  the 
  island. 
  The 
  

   men 
  at 
  the 
  National 
  MuHCum 
  have 
  done 
  their 
  usual 
  utmost 
  to 
  provide 
  

   facilities 
  and 
  as.sist 
  me 
  whenever 
  necessary.
