  Phlebotomus 
  roubaudi, 
  Newst.,

   I 
  have 
  recently 
  secured 
  another 
  male 
  of 
  this 
  species, 
  unfortunately 
  without 
  data, 
  

   but 
  as 
  it 
  agrees 
  in 
  all 
  the 
  structural 
  details 
  with 
  the 
  type, 
  now 
  in 
  the 
  Pasteur 
  Institute, 
  

   Paris, 
  I 
  have 
  added 
  a 
  few 
  more 
  details 
  and 
  a 
  figure 
  of 
  the 
  armature, 
  so 
  that 
  its 
  differen- 
  

   tial 
  characters 
  may 
  be 
  more 
  easily 
  followed. 
  On 
  comparing 
  the 
  illustration 
  of 
  the 
  

   armature 
  of 
  this 
  species 
  (fig. 
  8) 
  with 
  that 
  of 
  P. 
  papatasii* 
  the 
  marked 
  morphological 
  

   differences 
  which 
  exist 
  between 
  these 
  two 
  species 
  will 
  be 
  readily 
  seen. 
  The 
  male 
  

   genital 
  armature 
  is 
  relatively 
  large 
  and 
  in 
  general 
  outline 
  similar 
  to 
  that 
  of 
  P. 
  papa- 
  

   tasii 
  (Scop.) 
  ; 
  distal 
  segment 
  of 
  superior 
  claspers 
  (fig. 
  8, 
  b) 
  with 
  5 
  spines, 
  3 
  at 
  the 
  distal 
  

   extremity 
  and 
  2 
  widely 
  separated 
  from 
  them 
  and 
  also 
  from 
  each 
  other 
  ; 
  the 
  former 
  

   are 
  markedly 
  unequal 
  in 
  length 
  and 
  two 
  of 
  them 
  are 
  broadly 
  dilated 
  and 
  flattened 
  

   distally, 
  more 
  especially 
  the 
  central 
  one. 
  Inferior 
  claspers 
  (fig. 
  8, 
  di) 
  a 
  little 
  more 
  

   than 
  half 
  the 
  length 
  of 
  the 
  proximal 
  segment 
  of 
  the 
  superior 
  claspers, 
  apex 
  with 
  4-5 
  

   short 
  stout 
  spines 
  (5 
  is 
  apparently 
  the 
  normal 
  number) 
  ; 
  these 
  when 
  viewed 
  dorso- 
  

   ventrally 
  are 
  seen 
  to 
  be 
  spathuliform, 
  but 
  in 
  profile 
  they 
  appear 
  pointed 
  and 
  

   simple. 
  Median 
  fringed 
  process 
  (fig. 
  8, 
  c) 
  very 
  small 
  and 
  about 
  one-third 
  the 
  total 
  

   length 
  of 
  the 
  inferior 
  claspers. 
  Thus 
  the 
  armature 
  presents 
  four 
  well-marked 
  charac- 
  

   ters 
  by 
  means 
  of 
  which 
  it 
  may 
  be 
  distinguished 
  at 
  once 
  from 
  P. 
  papatasii 
  ; 
  these 
  are
