  — 
  NEW 
  SPECIES 
  OF 
  CULICIDAE 
  IN 
  THE 
  BRITISH 
  MUSEUM, 
  

  

  external 
  characters 
  can 
  be 
  adduced 
  for 
  their 
  separation. 
  The 
  hypopygium 
  of 
  C. 
  

   neavei 
  (fig. 
  4) 
  is 
  all 
  but 
  identical 
  with 
  that 
  of 
  C. 
  univittatus 
  (shown 
  for 
  comparison 
  

   with 
  C. 
  neavei 
  and 
  C. 
  simpsoni 
  in 
  fig. 
  5). 
  C. 
  neavei 
  can 
  hardly 
  be 
  a 
  variety 
  of 
  C. 
  

   univittatus, 
  as 
  the 
  hind 
  tibiae 
  are 
  altogether 
  devoid 
  of 
  the 
  white 
  lateral 
  stripe 
  and 
  

   have 
  scarcely 
  a 
  trace 
  of 
  a 
  pale 
  spot 
  at 
  the 
  apex. 
  

  

  A 
  more 
  careful 
  examination 
  of 
  the 
  type 
  male 
  of 
  C. 
  quasiguiarti 
  reveals 
  the 
  fact 
  that 
  

   it 
  is 
  really 
  a 
  specimen 
  of 
  C. 
  neavei 
  and 
  not 
  of 
  C. 
  pallidocephalus, 
  as 
  was 
  previously 
  

   suggested 
  (Bull. 
  Ent. 
  Res., 
  iv, 
  p. 
  56), 
  and 
  also 
  that 
  the 
  male 
  and 
  female 
  types 
  of 
  

   C. 
  quasiguiarti 
  probably 
  do 
  belong 
  to 
  the 
  same 
  species. 
  The 
  abdomen 
  is 
  not 
  really 
  

   banded, 
  although 
  it 
  is 
  rubbed 
  in 
  such 
  a 
  way 
  as 
  to 
  appear 
  so. 
  The 
  name 
  quasiguiarti 
  

   must 
  therefore 
  fall 
  as 
  a 
  synonym 
  of 
  C. 
  neavei 
  and 
  not 
  of 
  C. 
  pipiens 
  or 
  C. 
  pallidocephalus. 
  

   Single 
  male 
  specimens 
  of 
  C. 
  neavei 
  are 
  in 
  the 
  British 
  Museum 
  collection 
  from 
  Kampala 
  

   Swamp, 
  Uganda 
  (Capt. 
  A. 
  D. 
  Fraser) 
  and 
  Kisumu, 
  British 
  East 
  Africa 
  (Dr. 
  A. 
  Mouat). 
  

  

  Culex 
  guiarti, 
  Blanch. 
  

  

  The 
  hypopygium 
  of 
  the 
  type 
  male 
  of 
  this 
  species 
  is 
  too 
  damaged 
  for 
  purposes 
  of 
  

   illustration, 
  and 
  the 
  figure 
  (fig. 
  6) 
  has 
  therefore 
  been 
  made 
  from 
  a 
  specimen 
  from 
  

   Nairobi 
  (Dr. 
  C. 
  W. 
  Daniels) 
  which 
  was 
  first 
  carefully 
  compared 
  with 
  the 
  type. 
  

  

  Fig. 
  6. 
  — 
  Culex 
  guiarti, 
  Blanch. 
  

  

  It 
  was 
  found 
  on 
  examination 
  that 
  the 
  West 
  African 
  C. 
  grahami, 
  Theo. 
  has 
  a 
  hypopy- 
  

   gium 
  extremely 
  similar 
  to 
  that 
  of 
  C. 
  guiarti, 
  and 
  as 
  the 
  two 
  are 
  very 
  much 
  alike 
  in 
  

   external 
  characters, 
  it 
  seems 
  best 
  to 
  regard 
  them 
  as 
  merely 
  geographical 
  forms 
  of 
  the
