  THE

  whereas 
  the 
  front 
  of 
  the 
  male 
  albiceps 
  is 
  wider, 
  the 
  eyes 
  being 
  separated 
  by 
  a 
  

   distinct 
  interval 
  ; 
  there 
  are 
  also 
  other 
  minor 
  characters, 
  such 
  as 
  the 
  dorsum 
  of 
  the 
  

   thorax 
  of 
  putoria 
  being 
  partly 
  greyish 
  poUinose, 
  while 
  that 
  of 
  albiceps 
  is 
  shining 
  and 
  

   not 
  pollinose. 
  Using 
  these 
  characters, 
  I 
  have 
  examined 
  a 
  long 
  series 
  of 
  both 
  species 
  

   from 
  various 
  localities, 
  and 
  in 
  particular 
  a 
  small 
  collection 
  of 
  albiceps 
  taken 
  by 
  

   Major 
  Austen 
  from 
  the 
  Mount 
  of 
  Olives, 
  Palestine 
  : 
  also 
  many 
  hundreds 
  of 
  specimens 
  

   from 
  India 
  and 
  Australia. 
  The 
  Palestine 
  form 
  differs 
  from 
  the 
  Indian 
  in 
  the 
  following 
  

   respects 
  : 
  — 
  The 
  face 
  in 
  the 
  Palestine 
  females 
  is 
  much 
  more 
  silvery 
  white, 
  whereas 
  it 
  

   is 
  of 
  a 
  dirty 
  yellow 
  colour 
  in 
  the 
  Indian 
  specimens 
  ; 
  the 
  antennae 
  of 
  the 
  Palestine 
  

   species 
  are 
  not 
  nearly 
  so 
  red 
  as 
  those 
  of 
  the 
  Indian 
  forms 
  ; 
  the 
  palpi 
  are 
  darker 
  

   orange, 
  whereas 
  those 
  of 
  the 
  Indian 
  ones 
  are 
  lighter 
  orange 
  ; 
  the 
  abdominal 
  bands 
  

   are 
  narrower 
  than 
  in 
  the 
  specimens 
  from 
  India. 
  

  

  Most 
  of 
  the 
  specimens 
  collected 
  on 
  the 
  White 
  Nile 
  and 
  in 
  Sierra 
  Leone 
  agree 
  with 
  

   the 
  Indian 
  form 
  ; 
  the 
  African 
  males, 
  like 
  the 
  Indian, 
  have 
  a 
  narrower 
  front 
  than 
  

   those 
  of 
  the 
  Palestine 
  specimens. 
  But 
  on 
  examining 
  a 
  series 
  of 
  specimens 
  labelled 
  

   albiceps 
  in 
  the 
  National 
  Collection, 
  I 
  note 
  that 
  there 
  are 
  males 
  with 
  fronts 
  intermediate 
  

   between 
  the 
  Palestine 
  males 
  on 
  the 
  one 
  hand, 
  and 
  the 
  African 
  ones 
  on 
  the 
  other, 
  

   and 
  that 
  in 
  some 
  the 
  abdominal 
  bands 
  are 
  broad, 
  broader 
  than 
  the 
  Palestine 
  specimens 
  

   This 
  collection 
  also 
  contains 
  three 
  specimens 
  labelled 
  albiceps 
  var. 
  bibnla, 
  Wiedemann, 
  

   by 
  Dr. 
  Villeneuve 
  from 
  British 
  East 
  Africa 
  and 
  North 
  West 
  Rhodesia, 
  and 
  I 
  can 
  see 
  

   no 
  difference 
  between 
  these 
  and 
  the 
  Indian 
  forms 
  named 
  by 
  that 
  authority 
  as 
  putoria. 
  

   Therefore 
  without 
  going 
  any 
  further 
  into 
  the 
  identity 
  of 
  Wiedemann's 
  two 
  species, 
  

   it 
  is 
  quite 
  clear 
  that 
  there 
  are 
  two 
  distinct 
  forms 
  which 
  merge 
  into 
  each 
  other, 
  and 
  for 
  

   this 
  reason 
  I 
  prefer 
  in 
  the 
  meantime 
  to 
  place 
  both 
  under 
  the 
  name 
  albiceps, 
  including 
  

   Wiedemann's 
  variety 
  bibnla. 
  As 
  soon 
  as 
  I 
  have 
  completed 
  my 
  studies 
  of 
  the 
  external 
  

   genitalia 
  of 
  both 
  sexes 
  of 
  these 
  forms, 
  I 
  shall 
  be 
  in 
  a 
  position 
  to 
  express 
  a 
  final 
  opinion 
  

   as 
  to 
  whether 
  they 
  are 
  to 
  be 
  considered 
  distinct 
  species 
  or 
  mere 
  racial 
  forms. 
  

  

  Major 
  Austen 
  kindly 
  showed 
  me 
  some 
  larvae 
  which 
  he 
  collected 
  among 
  some 
  

   weeds 
  when 
  searching 
  for 
  Anopheles 
  larvae 
  in 
  Palestine, 
  and 
  on 
  examining 
  them 
  

   macroscopically, 
  I 
  could 
  see 
  no 
  difference 
  between 
  them 
  and 
  the 
  larvae 
  of 
  the 
  species 
  

   from 
  India. 
  Both 
  have 
  the 
  same 
  type 
  of 
  fleshy 
  processes 
  with 
  a 
  tuft 
  of 
  spines 
  at 
  

   their 
  apices, 
  and 
  short 
  of 
  examining 
  them 
  microscopically 
  I 
  consider 
  they 
  are 
  identical. 
  

   I 
  am 
  of 
  course 
  assuming 
  that 
  they 
  are 
  the 
  larvae 
  of 
  albiceps, 
  though 
  there 
  is 
  no 
  proof 
  

   of 
  this, 
  as 
  the 
  flies 
  were 
  not 
  bred 
  from 
  them. 
  I 
  trust 
  those 
  who 
  have 
  opportunities 
  

   of 
  collecting 
  larvae 
  of 
  either 
  form, 
  but 
  especially 
  albiceps, 
  will 
  send 
  me 
  larvae 
  for 
  

   microscopic 
  study. 
  

  

  There 
  is 
  an 
  interesting 
  specimen 
  in 
  the 
  National 
  Collection 
  of 
  what 
  conforms 
  to 
  

   the 
  putoria 
  type, 
  from 
  Lourenco 
  Marques, 
  bred 
  from 
  a 
  larva 
  from 
  an 
  infected 
  human 
  

   sore. 
  I 
  have 
  compared 
  this 
  specimen 
  with 
  the 
  Indian 
  and 
  Palestine 
  species, 
  and 
  find 
  

   that 
  the 
  face 
  is 
  as 
  white 
  as 
  that 
  of 
  the 
  Palestine 
  females, 
  and 
  the 
  abdominal 
  bands 
  

   are 
  broader. 
  It 
  is 
  evident 
  then 
  that 
  this 
  form 
  may 
  cause 
  human 
  myiasis 
  in 
  man. 
  

   I 
  have 
  no 
  record 
  of 
  this 
  hairy 
  larva 
  from 
  human 
  or 
  animal 
  tissues 
  in 
  India, 
  though, 
  

   of 
  course, 
  Chrysomyia 
  rufifacies 
  commonly 
  attacks 
  sheep 
  in 
  Australia. 
  

  

  Lucilia 
  r 
  it 
  fades 
  is 
  recorded 
  by 
  Macquart 
  as 
  a 
  species 
  described 
  by 
  Guerin, 
  but 
  so 
  

   far 
  I 
  have 
  failed 
  to 
  find 
  Guerin-Meneville's 
  description 
  of 
  this 
  species 
  and 
  do 
  not 
  know 
  

   where 
  it 
  was 
  published 
  ; 
  Macquart 
  says 
  the 
  species 
  is 
  from 
  Australia. 
  I 
  have 
  

   examined 
  a 
  large 
  number 
  of 
  specimens 
  of 
  this 
  species 
  from 
  the 
  Australian 
  region 
  in 
  

   the 
  National 
  Collection 
  as 
  well 
  as 
  in 
  my 
  own, 
  and 
  note 
  that 
  many 
  of 
  the 
  males 
  have 
  

   fronts 
  as 
  narrow 
  as 
  the 
  form 
  putoria, 
  others 
  have 
  fronts 
  as 
  wide 
  as 
  those 
  of 
  the 
  males 
  

   of 
  the 
  Palestine 
  albiceps 
  form 
  noted 
  above, 
  so 
  that 
  here 
  again 
  we 
  have 
  a 
  variable 
  

   species, 
  and 
  it 
  is 
  very 
  evident 
  that 
  it 
  will 
  be 
  necessary 
  to 
  make 
  a 
  much 
  more 
  exhaustive 
  

   study 
  of 
  all 
  three 
  forms 
  to 
  find 
  the 
  limits 
  of 
  variation 
  as 
  well 
  as 
  the 
  characters 
  of 
  the 
  

   external 
  genitalia. 
  I 
  shall 
  be 
  glad 
  to 
  have 
  a 
  large 
  number 
  of 
  specimens 
  from 
  the 
  

   Australian 
  region 
  in 
  order 
  to 
  complete 
  this 
  work.
