  This 
  species 
  is 
  almost 
  certainly 
  identical 
  with 
  Neotnacleaya 
  australis, 
  Taylor, 
  

  

  described 
  from 
  N. 
  Queensland, 
  but 
  that 
  specific 
  name 
  is 
  preoccupied 
  in 
  Culex 
  bv 
  

   C. 
  australis, 
  Erichson. 
  The 
  nearest 
  ally 
  seems 
  to 
  be 
  the 
  Malayan 
  C. 
  (L).quadripalpis, 
  

   Edw., 
  which 
  differs 
  in 
  its 
  lighter 
  colour, 
  hairy 
  q 
  palpi, 
  and 
  slightly 
  different 
  antennal 
  

   characters. 
  

  

  Culex 
  basicinctus, 
  Edw. 
  

  

  I 
  proposed 
  this 
  name 
  (Bull. 
  Ent. 
  Res., 
  xii, 
  p. 
  78, 
  1921) 
  for 
  some 
  specimens 
  sent 
  

   by 
  Mr. 
  G. 
  F. 
  Hill 
  from 
  Queensland 
  as 
  Leucomyia 
  annulirostris, 
  Taylor, 
  but 
  which 
  

   I 
  believed 
  to 
  be 
  Leucomyia 
  annidata, 
  Taylor 
  ; 
  I 
  believed 
  the 
  new 
  name 
  to 
  be 
  necessary 
  

   because 
  L. 
  annidata 
  was 
  preoccupied 
  by 
  Theobaldia 
  {Culex) 
  annulata, 
  Schrank, 
  

   Culex 
  (Trichopronomyia) 
  annidata, 
  Theobald, 
  and 
  C. 
  (Culicioinyia) 
  annulata, 
  Theobald. 
  

   It 
  now 
  appears 
  that 
  the 
  specimens 
  before 
  me 
  were 
  not 
  Taylor's 
  L. 
  annulata, 
  nor 
  

   were 
  they 
  his 
  L. 
  annulirostris, 
  but 
  a 
  distinct 
  and 
  hitherto 
  undescribed 
  species. 
  I 
  

   am 
  indebted 
  to 
  Mr. 
  G. 
  F. 
  Hill 
  for 
  the 
  loan 
  of 
  the 
  types 
  of 
  both 
  Taylor's 
  species. 
  The 
  

   type 
  male 
  of 
  L. 
  annulata 
  has 
  unfortunately 
  lost 
  the 
  tip 
  of 
  its 
  abdomen, 
  but 
  is 
  almost 
  

   certainly 
  identical 
  with 
  Leucomyia 
  vicina, 
  Taylor 
  ; 
  this 
  again 
  may 
  prove 
  the 
  same 
  

   as 
  Skuse's 
  Culex 
  annulirostris, 
  Theobald's 
  interpretation 
  of 
  this 
  species 
  being 
  

   certainly 
  incorrect. 
  Taylor's 
  Leucomyia 
  annulirostris 
  is 
  a 
  distinct 
  species, 
  but 
  is 
  

   identical 
  with 
  his 
  Cidicada 
  squamosa, 
  as 
  I 
  have 
  ascertained 
  by 
  comparison 
  of 
  the 
  

   types. 
  

  

  Since 
  my 
  name 
  Cidex 
  basicinctus 
  was 
  actually 
  proposed 
  as 
  a 
  substitute 
  for 
  

   Leucomyia 
  annidata, 
  it 
  might 
  perhaps 
  be 
  strictly 
  logical 
  to 
  place 
  it 
  now 
  as 
  a 
  synonym 
  

   of 
  C. 
  vicinus 
  ; 
  but 
  in 
  proposing 
  the 
  name 
  I 
  mentioned 
  some 
  diagnostic 
  characters 
  

   of 
  the 
  species 
  I 
  had 
  wrongly 
  determined 
  as 
  L. 
  annulata, 
  and 
  this 
  fact 
  will 
  perhaps 
  

   be 
  sufficient 
  to 
  permit 
  the 
  retention 
  of 
  the 
  new 
  name 
  for 
  the 
  new 
  species. 
  The 
  

   synonymy 
  of 
  the 
  three 
  species 
  concerned 
  will 
  therefore 
  be 
  as 
  follows 
  :
