  NOTES 
  ON 
  THE 
  CALLIPHORINAE. 
  PART 
  I. 
  THE 
  ORIENTAL 
  SPECIES 
  

  

  By 
  Major 
  W. 
  S. 
  Patton, 
  M.B., 
  F.E.S., 
  I.M.S. 
  (retd.), 
  

   Lecturer 
  on 
  Entomology 
  and 
  Parasitology 
  , 
  Edinburgh 
  University. 
  

  

  For 
  many 
  years 
  I 
  have 
  collected 
  and 
  bred 
  the 
  Indian 
  Calliphorinae, 
  and 
  recently 
  

   contributed 
  a 
  number 
  of 
  papers 
  describing 
  the 
  common 
  species. 
  In 
  the 
  first 
  of 
  these, 
  

   which 
  appeared 
  in 
  a 
  recent 
  number 
  of 
  the 
  Indian 
  Journal 
  of 
  Medical 
  Research 
  (viii, 
  

   no. 
  1, 
  July 
  1920), 
  I 
  described 
  in 
  some 
  detail 
  the 
  egg, 
  larva, 
  puparium 
  and 
  adults 
  of 
  

   Chrysomyia 
  bezziana, 
  Villeneuve, 
  the 
  Old 
  World 
  screw-worm 
  fly, 
  and 
  pointed 
  out 
  

   that 
  this 
  species 
  is 
  a 
  specific 
  myiasis-producing 
  Calliphorine, 
  only 
  breeding 
  in 
  living 
  

   tissues, 
  and 
  that 
  its 
  larvae 
  may 
  be 
  found 
  in 
  all 
  forms 
  of 
  cutaneous, 
  subcutaneous, 
  

   nasal, 
  oral, 
  aural 
  and 
  vaginal 
  myiasis 
  in 
  man 
  and 
  animals. 
  In 
  the 
  succeeding 
  papers 
  

   I 
  described 
  the 
  larvae, 
  puparia 
  and 
  adults 
  of 
  the 
  other 
  common 
  species, 
  two 
  of 
  which, 
  

   Chrysomyia 
  megacephala 
  and 
  Lucilia 
  argyricephala, 
  occasionally 
  cause 
  mviasis 
  in 
  

   animals 
  in 
  India. 
  It 
  was 
  not 
  possible 
  at 
  the 
  time 
  to 
  determine 
  the 
  non-myiasis- 
  

   producing 
  species, 
  and 
  new 
  names 
  were 
  given 
  them. 
  But 
  recently, 
  when 
  studying 
  

   the 
  species 
  of 
  Musca 
  in 
  the 
  National 
  Collection 
  at 
  the 
  British 
  Museum, 
  I 
  was 
  able 
  

   to 
  examine 
  Walker's 
  types 
  and 
  am 
  now 
  in 
  a 
  position 
  to 
  give 
  these 
  Indian 
  species 
  

   their 
  correct 
  names. 
  At 
  the 
  same 
  time 
  I 
  have 
  examined 
  all 
  the 
  Calliphorine 
  material 
  

   in 
  the 
  National 
  Collection 
  from 
  other 
  parts 
  of 
  the 
  world, 
  as 
  well 
  as 
  many 
  specimens 
  

   in 
  my 
  own 
  collection, 
  and 
  I 
  propose 
  in 
  this 
  and 
  in 
  succeeding 
  notes 
  to 
  collect 
  together 
  

   all 
  the 
  results 
  of 
  my 
  studies 
  with 
  a 
  view 
  to 
  revising 
  later 
  the 
  species 
  of 
  blow-flies. 
  

   Here 
  again 
  I 
  am 
  deeply 
  indebted 
  to 
  Major 
  E. 
  E. 
  Austen, 
  D.S.O., 
  for 
  the 
  valuable 
  

   help 
  he 
  has 
  given 
  me 
  in 
  this 
  work. 
  

  

  As 
  I 
  have 
  a 
  large 
  number 
  of 
  specimens 
  of 
  Chrysomyia 
  bezziana 
  and 
  its 
  larvae, 
  as 
  

   well 
  as 
  adults 
  and 
  larvae 
  of 
  all 
  the 
  other 
  Indian 
  species, 
  I 
  shall 
  be 
  very 
  glad 
  to 
  

   exchange 
  any 
  of 
  these 
  species 
  with 
  any 
  Dipterologist 
  for 
  specimens 
  from 
  other 
  

   localities. 
  In 
  the 
  present 
  paper 
  I 
  record 
  my 
  preliminary 
  studies 
  of 
  the 
  Oriental 
  

   species, 
  and 
  shall 
  deal 
  with 
  those 
  from 
  other 
  regions 
  in 
  subsequent 
  notes. 
  

  

  1. 
  Chrysomyia 
  bezziana, 
  Villeneuve. 
  

  

  Synonyms 
  : 
  Chrysomyia 
  dux, 
  Escholz 
  (apud 
  Sinton 
  and 
  authors). 
  

   Chrysomyia 
  flaviceps, 
  Macquart 
  (of 
  authors). 
  

  

  This 
  species 
  is 
  rarely 
  seen 
  in 
  its 
  adult 
  stage 
  as 
  it 
  does 
  not 
  breed 
  in 
  decaying 
  

   animal 
  matter 
  and 
  is 
  only 
  attracted 
  to 
  diseased 
  human 
  and 
  animal 
  tissues. 
  Almost 
  

   every 
  Medical 
  and 
  Veterinary 
  Officer 
  in 
  India 
  has, 
  on 
  the 
  other 
  hand, 
  seen 
  its 
  larvae 
  

   in 
  all 
  forms 
  of 
  myiasis 
  in 
  man 
  and 
  animals. 
  Since 
  my 
  last 
  record 
  of 
  the 
  larvae 
  of 
  

   C. 
  bezziana 
  from 
  human 
  tissues, 
  I 
  have 
  received 
  four 
  male 
  specimens 
  from 
  Mr. 
  T. 
  

   Bainbrigge 
  Fletcher, 
  Imperial 
  Entomologist, 
  India, 
  bred 
  from 
  wounds 
  on 
  the 
  soft 
  

   palate 
  of 
  a 
  patient 
  in 
  the 
  Pusa 
  hospital. 
  And 
  in 
  a 
  recent 
  paper 
  Sinton 
  (Ind. 
  Jl. 
  

   Med. 
  Res. 
  ix, 
  no. 
  1, 
  July 
  1921) 
  records 
  two 
  cases 
  of 
  human 
  myiasis 
  — 
  nasal 
  and 
  buccal 
  — 
  

   from 
  Kohat, 
  North 
  West 
  Frontier 
  Province, 
  India, 
  in 
  which 
  he 
  describes 
  the 
  larva 
  

   from 
  Case 
  1 
  clearly 
  showing 
  that 
  it 
  was 
  that 
  of 
  C. 
  bezziana 
  ; 
  and 
  I 
  have 
  little 
  doubt 
  

   that 
  those 
  from 
  Case 
  2 
  also 
  belonged 
  to 
  this 
  species. 
  

  

  Chrysomyia 
  bezziana 
  is 
  the 
  most 
  important 
  myiasis-producing 
  Calliphorine 
  in 
  

   India, 
  and 
  now 
  that 
  its 
  larvae 
  have 
  been 
  fully 
  described, 
  Medical 
  and 
  Veterinary 
  

   Officers 
  should 
  find 
  no 
  difficulty 
  in 
  recognising 
  them 
  when 
  they 
  come 
  across 
  them 
  in 
  

   the 
  course 
  of 
  their 
  work, 
  and 
  I 
  hope 
  that 
  if 
  they 
  find 
  any 
  larvae 
  which 
  do 
  not 
  agree 
  

   with 
  these 
  descriptions, 
  that 
  they 
  will 
  send 
  them 
  to 
  me 
  preserved 
  in 
  spirit. 
  Any 
  

   larvae 
  of 
  this 
  species 
  from 
  other 
  parts 
  of 
  the 
  Oriental 
  region 
  other 
  than 
  India 
  would 
  

   be 
  welcome.
