  he 
  states 
  : 
  " 
  I 
  received 
  and 
  examined 
  your 
  Phlebotomus. 
  It 
  is 
  certainly 
  of 
  the 
  type 
  

   of 
  longipalpis, 
  though 
  I 
  seemed 
  to 
  notice 
  some 
  little 
  differences 
  by 
  comparing 
  another 
  j 
  

   male 
  in 
  microscopical 
  preparation. 
  Those, 
  however, 
  might 
  be 
  due 
  to 
  accidents 
  in

  position 
  and 
  preparation. 
  The 
  place 
  where 
  it 
  was 
  found 
  speaks 
  also 
  for 
  it, 
  as 
  

   palpis 
  has 
  a 
  very 
  wide 
  range. 
  It 
  certainly 
  is 
  not 
  the 
  species 
  of 
  Sophia 
  Summers, 
  

   nor 
  a 
  larger 
  undescribed 
  one 
  I 
  brought 
  from 
  Southern 
  Brazil, 
  which 
  has 
  the 
  antennae 
  

  

  of 
  the 
  same 
  type 
  as 
  longipalpis. 
  The 
  new 
  species 
  from 
  Trinidad 
  and 
  Peru 
  

  

  described 
  by 
  Knab 
  and 
  Townsend 
  have 
  the 
  same 
  type 
  of 
  antennae, 
  but 
  seem 
  to 
  be 
  

  

  different, 
  though 
  I 
  do 
  not 
  feel 
  sure 
  about 
  it 
  The 
  feet 
  seem 
  rather 
  heavily 
  

  

  scaled 
  in 
  your 
  specimens." 
  This 
  leaves 
  one 
  still 
  in 
  doubt 
  as 
  to 
  the 
  specific 
  identity 
  

   of 
  Dr. 
  Walker's 
  material, 
  the 
  outstanding 
  features 
  of 
  which 
  are 
  so 
  strikingly 
  charac- 
  

   teristic 
  that 
  I 
  fail 
  to 
  understand 
  how 
  it 
  was 
  that 
  Dr. 
  Lutz 
  was 
  unable 
  to 
  determine 
  

   definitely 
  the 
  specimen 
  submitted 
  to 
  him. 
  In 
  view, 
  therefore, 
  of 
  the 
  slight 
  discrepan- 
  

   cies 
  which 
  Lutz 
  has 
  observed, 
  and 
  also 
  that 
  there 
  exist 
  in 
  my 
  specimens 
  certain 
  

   taxonomic 
  characters 
  which 
  have, 
  apparently, 
  been 
  overlooked, 
  it 
  may 
  be 
  desirable 
  

   to 
  call 
  attention 
  to 
  these, 
  so 
  that 
  in 
  future 
  the 
  insect 
  may 
  be 
  determined 
  the 
  more 
  

   readily. 
  

  

  9- 
  — 
  Antennae 
  of 
  16 
  segments, 
  the 
  3rd 
  relatively 
  very 
  short 
  ; 
  5th 
  reaching 
  to 
  the 
  tip 
  

   of 
  the 
  proboscis 
  ; 
  3rd 
  and 
  4th 
  together 
  a 
  little 
  longer 
  than 
  the 
  5th 
  segment 
  of 
  the 
  palpi 
  ; 
  

   geniculated 
  spines 
  present 
  on 
  the 
  3rd 
  to 
  the 
  15th, 
  inclusive 
  ; 
  those 
  on 
  the 
  11th- 
  15th 
  

   (fig. 
  10, 
  a) 
  of 
  great 
  length, 
  the 
  tips 
  reaching 
  to 
  the 
  articulation 
  of 
  the 
  succeeding 
  

   segment 
  and 
  in 
  some 
  instances 
  slightly 
  beyond 
  ; 
  the 
  length 
  of 
  the 
  spines 
  on 
  the 
  other 
  

   segments 
  not 
  determinable 
  in 
  my 
  preparations, 
  but 
  all 
  of 
  them 
  appear 
  to 
  be 
  unusually 
  

   long, 
  differing 
  markedly 
  in 
  this 
  respect 
  from 
  those 
  observed 
  in 
  the 
  African 
  and 
  

   European 
  species. 
  Legs 
  densely 
  scaled, 
  the 
  individual 
  scales 
  long 
  and 
  narrowly 
  

   lanceolate.
