  Culex 
  salisburiensis, 
  Theo. 
  

  

  As 
  in 
  the 
  case 
  of 
  C. 
  rima, 
  the 
  abdominal 
  markings 
  of 
  this 
  species 
  are 
  variable, 
  

   the 
  tergites 
  sometimes 
  having 
  complete 
  apical 
  white 
  bands, 
  sometimes 
  lateral 
  spots 
  

   only. 
  The 
  species 
  may 
  be 
  known 
  from 
  its 
  allies 
  by 
  the 
  possession 
  of 
  a 
  large 
  patch 
  

   of 
  scales 
  on 
  the 
  basal 
  half 
  of 
  the 
  mesepimeron. 
  The 
  lower 
  mesepimeral 
  bristle 
  is 
  

   present. 
  Hypopygium 
  : 
  side-piece 
  much 
  as 
  in 
  C. 
  rima, 
  but 
  clasper 
  somewhat 
  

   bent. 
  Mesosomal 
  lobes 
  flat, 
  pale, 
  and 
  devoid 
  of 
  tubercles. 
  Tenth 
  sternites 
  with 
  

   few 
  spines, 
  the 
  inner 
  ones 
  bristly, 
  the 
  outer 
  ones 
  stout 
  and 
  blunt-tipped.

  Protomelanoconion 
  fusca,

  (1910). 
  

  

  This 
  change 
  of 
  name 
  is 
  necessary 
  since 
  the 
  specific 
  name 
  fuscus 
  is 
  preoccupied 
  

   in 
  Culex 
  by 
  Tr 
  ichor 
  hynchus 
  fuscus, 
  Theo. 
  The 
  species 
  is 
  extremely 
  close 
  to 
  the 
  

   Oriental 
  C. 
  brevipalpis, 
  Giles, 
  but 
  differs 
  rather 
  noticeably 
  in 
  the 
  structure 
  of 
  the 
  

   aedoeagus. 
  This 
  organ 
  is 
  of 
  simple 
  structure, 
  with 
  the 
  lobes 
  tubercular, 
  as 
  in 
  several 
  

   species 
  of 
  the 
  rima 
  group. 
  The 
  clasper 
  is 
  simple. 
  It 
  can 
  hardly 
  be 
  included 
  in 
  the 
  

   rima 
  group 
  since 
  the 
  abdominal 
  tergites 
  have 
  basal 
  instead 
  of 
  apical 
  pale 
  spots 
  ; 
  

   moreover 
  the 
  species 
  is 
  well 
  distinguished 
  from 
  all 
  other 
  Ethiopian 
  species 
  except 
  

   C. 
  inconspicuosus 
  by 
  the 
  unusually 
  long 
  and 
  stout 
  bristles 
  which 
  occur 
  over 
  nearly 
  

   the 
  whole 
  of 
  the 
  mesonotum. 
  This 
  character 
  (which 
  has 
  suggested 
  the 
  specific 
  

   name), 
  together 
  with 
  the 
  absence 
  of 
  flat 
  scales 
  on 
  the 
  top 
  of 
  the 
  head, 
  may 
  perhaps 
  

   be 
  used 
  to 
  define 
  the 
  subgenus, 
  which 
  should 
  probably 
  include 
  some 
  species 
  in 
  which 
  

   the 
  palpi 
  are 
  alike 
  in 
  the 
  two 
  sexes 
  ; 
  among 
  others, 
  perhaps, 
  the 
  type-species 
  of 
  

   Micraedes.

  Although 
  very 
  similar 
  in 
  general 
  appearance 
  to 
  C. 
  horridus, 
  this 
  species 
  may 
  be 
  

   readily 
  distinguished 
  from 
  all 
  other 
  African 
  Culex 
  by 
  the 
  entire 
  replacement 
  of 
  the 
  

   narrow 
  scales 
  of 
  the 
  head 
  by 
  flat 
  ones. 
  The 
  abdomen 
  is 
  without 
  pale 
  markings. 
  

   As 
  in 
  C. 
  horridus 
  there 
  is 
  a 
  single 
  well-marked 
  lower 
  mesepimeral 
  bristle. 
  The 
  

   male 
  aedoeagus 
  has 
  the 
  simple 
  type 
  of 
  structure, 
  but 
  the 
  clasper 
  is 
  peculiar 
  in 
  having 
  

   a 
  large 
  projecting 
  dorsal 
  process. 
  The 
  Oriental 
  C. 
  malayi 
  is 
  closely 
  allied 
  but 
  quite 
  

   distinct. 
  

  

  I 
  have 
  referred 
  this 
  species 
  to 
  the 
  subgenus 
  Micraedes 
  on 
  account 
  of 
  the 
  very 
  

   short 
  male 
  palpi. 
  It 
  differs, 
  however, 
  from 
  the 
  type 
  of 
  the 
  subgenus 
  (M. 
  bisulcatits, 
  

   Coq.) 
  in 
  its 
  flat-scaled 
  head 
  and 
  forked 
  claspers, 
  both 
  these 
  characters 
  being 
  of 
  more 
  

   importance 
  than 
  those 
  of 
  the 
  palpi. 
  If, 
  therefore, 
  it 
  is 
  desired 
  to 
  place 
  it 
  in 
  a 
  separate 
  

   subgenus, 
  a 
  new 
  name 
  will 
  probably 
  have 
  to 
  be 
  proposed, 
  unless 
  the 
  insufficiently 
  

   known 
  Aedinus, 
  Lutz, 
  should 
  prove 
  to 
  be 
  applicable.

  Theobald's 
  specific 
  name 
  being 
  preoccupied 
  by 
  Ins 
  Aides 
  inconspicuosus 
  (both 
  

   species 
  really 
  belonging 
  to 
  Culex) 
  the 
  above 
  change 
  of 
  name 
  is 
  necessary. 
  

  

  There 
  are 
  two 
  varieties 
  of 
  this 
  species 
  : 
  in 
  one 
  the 
  mesonotal 
  scales 
  are 
  all 
  blackish, 
  

   in 
  the 
  other 
  there 
  are 
  large 
  whitish 
  patches 
  on 
  the 
  shoulders. 
  The 
  two 
  are 
  identical 
  

   in 
  all 
  other 
  respects. 
  The 
  species 
  may 
  be 
  easily 
  known 
  by 
  the 
  black 
  dorsum 
  and 
  

   pure 
  white 
  venter 
  ; 
  as 
  well 
  as 
  by 
  the 
  head 
  scaling 
  and 
  the 
  palpal 
  structure 
  of 
  both 
  

   sexes 
  The 
  hypopygial 
  structure 
  is 
  as 
  in 
  Culiciomyia, 
  but 
  the 
  absence 
  of 
  a 
  comb 
  

   of 
  scales 
  on 
  the 
  male 
  palpi 
  excludes 
  the 
  species 
  from 
  that 
  subgenus.
