  If 
  the 
  foregoing 
  description 
  of 
  the 
  wing 
  is 
  compared 
  with 
  that 
  given 
  by 
  Annandale* 
  

   it 
  will 
  be 
  seen 
  that 
  there 
  are 
  marked 
  differences 
  regarding 
  the 
  relative 
  length 
  of 
  the 
  

   anterior 
  branch 
  of 
  the 
  second 
  long 
  vein. 
  Annandale 
  describes 
  this 
  as 
  being 
  " 
  nearly 
  

   five 
  times 
  as 
  long 
  as 
  the 
  distance 
  between 
  the 
  two 
  forks," 
  though 
  in 
  his 
  illustration 
  

   (fig. 
  5) 
  the 
  vein 
  in 
  question 
  is 
  shown 
  as 
  being 
  only 
  slightly 
  more 
  than 
  three 
  times 
  the 
  

   length 
  of 
  the 
  distance 
  between 
  the 
  two 
  forks. 
  In 
  a 
  later 
  communication 
  (§), 
  however, 
  

  

  he 
  makes 
  the 
  following 
  statement 
  : 
  "It 
  should 
  be 
  noted 
  that 
  the 
  figure 
  of 
  P. 
  

  

  zeylanicus 
  printed 
  in 
  my 
  former 
  paper 
  (p. 
  60, 
  fig. 
  4) 
  gives, 
  because 
  of 
  the 
  angle 
  at 
  

   which 
  the 
  wing 
  was 
  drawn, 
  a 
  somewhat 
  incorrect 
  idea 
  of 
  the 
  venation 
  in 
  that 
  species 
  ; 
  

   fig. 
  5 
  on 
  the 
  same 
  page 
  is 
  more 
  exact 
  in 
  this 
  respect." 
  This 
  is 
  somewhat 
  difficult 
  of 
  

   interpretation, 
  as 
  it 
  leaves 
  one 
  still 
  in 
  doubt 
  as 
  to 
  whether 
  we 
  are 
  to 
  consider 
  his 
  

   diagnosis 
  as 
  correct 
  or 
  his 
  illustration 
  (fig. 
  5) 
  ; 
  for 
  the 
  present 
  both 
  must 
  be 
  accepted 
  as 
  

   indicating 
  exceptional 
  variation 
  in 
  the 
  wing 
  venation. 
  I 
  have 
  ventured 
  to 
  call 
  

   attention 
  to 
  this 
  because 
  I 
  find, 
  as 
  already 
  stated, 
  that 
  in 
  the 
  examples 
  collected

  by 
  Mr. 
  Rutherford 
  the 
  anterior 
  branch 
  of 
  the 
  second 
  vein 
  is 
  only 
  two 
  and 
  one-third 
  

   times 
  the 
  length 
  of 
  the 
  space 
  between 
  the 
  forks. 
  In 
  other 
  respects 
  the 
  venation 
  

   agrees, 
  especially 
  in 
  regard 
  to 
  the 
  position 
  of 
  the 
  tip 
  of 
  the 
  first 
  longitudinal 
  vein, 
  

   which 
  is, 
  as 
  Annandale 
  states, 
  far 
  in 
  advance 
  of 
  the 
  anterior 
  branch 
  of 
  the 
  second. 
  

   P. 
  malabaricus, 
  Annandale, 
  presents 
  a 
  similar 
  wing 
  venation 
  to 
  that 
  of 
  P. 
  zeylanicus, 
  

   but 
  on 
  the 
  whole 
  my 
  examples 
  agree 
  best 
  with 
  the 
  latter. 
  There 
  the 
  matter 
  must 
  

   stand 
  until 
  more 
  material 
  is 
  available. 
  Pairs 
  in 
  coitu 
  are 
  much 
  needed, 
  and 
  I 
  sincerely 
  

   trust 
  that 
  Mr. 
  Rutherford 
  will 
  be 
  successful 
  in 
  securing 
  these.

   So 
  far 
  as 
  I 
  can 
  possibly 
  ascertain 
  at 
  the 
  moment 
  there 
  is 
  a 
  measure 
  of 
  doubt 
  as 
  to 
  

   whether 
  the 
  specimens 
  recorded 
  above 
  are 
  specifically 
  identical 
  with 
  Phlebotomus 
  

   longipalpis 
  described 
  by 
  Lutz 
  & 
  Neiva.

  Finding 
  it 
  impossible 
  to 
  determine 
  Dr. 
  

   Walker's 
  material 
  from 
  the 
  author's 
  description 
  alone, 
  I 
  submitted 
  an 
  example 
  of 
  

   the 
  male 
  to 
  Dr. 
  Lutz 
  (carefully 
  prepared 
  for 
  microscopical 
  examination).
