  It 
  

   will 
  be 
  noticed 
  that 
  with 
  the 
  exception 
  of 
  two, 
  namely 
  C. 
  fatigans 
  and 
  8. 
  vittata, 
  

   the 
  species 
  found 
  in 
  Accra 
  and 
  in 
  the 
  towns 
  and 
  villages 
  of 
  the 
  Northern 
  Territories 
  

   are 
  identical. 
  C. 
  fatigans 
  has 
  yet 
  to 
  be 
  recorded 
  from 
  the 
  Northern 
  Territories 
  

   and 
  8. 
  vittata 
  from 
  Accra. 
  An 
  erroneous 
  impression 
  is 
  apt 
  to 
  be 
  given 
  by 
  the 
  

   above 
  figures, 
  as 
  although 
  8. 
  fasciata 
  was 
  found 
  in 
  77 
  per 
  cent, 
  of 
  the 
  villages 
  and 
  

   towns 
  visited, 
  it 
  is 
  to 
  be 
  remembered 
  that 
  it 
  was 
  specially 
  looked 
  for 
  and 
  in 
  many 
  

   instances 
  was 
  not 
  found 
  without 
  prolonged 
  and 
  careful 
  search. 
  It 
  is 
  a 
  much 
  rarer 
  

   mosquito 
  in 
  point 
  of 
  numbers 
  in 
  the 
  Northern 
  Territories 
  than 
  in 
  Accra 
  and 
  in 
  

   the 
  coast 
  towns 
  generally. 
  The 
  possible 
  effect 
  upon 
  disease 
  and 
  its 
  transference 
  

   of 
  the 
  higher 
  proportional 
  representation 
  of 
  the 
  other 
  domestic 
  Culicines 
  in 
  the 
  

   Northern 
  Territories, 
  as 
  compared 
  with 
  Accra, 
  is 
  an 
  interesting 
  subject 
  for 
  

   speculation. 
  

  

  Filariasis 
  and 
  diseases 
  usually 
  associated 
  with 
  Filaria 
  bancrofti 
  are 
  stated 
  by 
  

   Medical 
  Officers 
  who 
  have 
  been 
  stationed 
  on 
  the 
  northern 
  boundary 
  of 
  the 
  Northern 
  

   Territories 
  to 
  be 
  common 
  ; 
  if 
  this 
  be 
  the 
  case 
  the 
  role 
  played 
  by 
  Culex 
  fatigans 
  must 
  be 
  

   taken 
  by 
  some 
  other 
  species. 
  A. 
  costalis, 
  Mansonioides 
  uniformis 
  and 
  8. 
  fasciata 
  are 
  

   recognised 
  potential 
  carriers, 
  and 
  Culex 
  duttoni 
  " 
  was 
  found 
  to 
  be 
  one 
  of 
  the 
  hosts 
  of 
  

   Filaria

  Phlebotomus 
  was 
  taken 
  on 
  the 
  walls 
  of 
  most 
  of 
  the 
  Rest 
  Houses 
  ; 
  and 
  as 
  these 
  walls 
  

   are 
  usually 
  composed 
  of 
  swish 
  mixed 
  with 
  a 
  certain 
  proportion 
  of 
  dung, 
  they 
  offer, 
  

   when 
  they 
  become 
  seamed 
  with 
  fissures, 
  ideal 
  breeding 
  places 
  for 
  these 
  insects. 
  

   Possibly 
  the 
  washing 
  of 
  the 
  mud 
  walls 
  of 
  the 
  Rest 
  Houses 
  with 
  extract 
  of 
  " 
  dawa- 
  

   dawa 
  " 
  trees 
  (Parkia 
  biglobosa) 
  has 
  some 
  efficacy 
  in 
  diminishing 
  the 
  breeding 
  places 
  of 
  

   Phlebotomus, 
  as 
  it 
  certainly 
  seems 
  to 
  prevent 
  the 
  walls 
  from 
  cracking 
  ; 
  washing 
  with 
  

   wood 
  ash 
  is 
  not 
  nearly 
  so 
  effectual. 
  As 
  Phlebotomus 
  is 
  not 
  partial 
  to 
  light 
  or 
  breezes, 
  

   this 
  is 
  the 
  probable 
  explanation 
  of 
  its 
  rarity 
  upon 
  the 
  walls 
  of 
  the 
  Rest 
  Houses 
  in 
  the 
  

   Lorha 
  District, 
  which 
  are 
  the 
  largest, 
  best 
  lighted 
  and 
  best 
  ventilated 
  of 
  any 
  in 
  the 
  

   Northern 
  Territories. 
  

  

  Pappataci 
  fever 
  has 
  been 
  reported 
  from 
  Nigeria 
  (Yellow 
  Fever 
  Commission 
  Fourth 
  

   and 
  Final 
  Report, 
  pp. 
  13-17); 
  it 
  is 
  almost 
  certain 
  that 
  it 
  also 
  occurs 
  in 
  the 
  

   Gold 
  Coast. 
  

  

  Oulicoides 
  were 
  taken 
  in 
  the 
  evenings 
  at 
  several 
  places 
  and 
  were 
  felt 
  and 
  seen 
  at 
  

   others 
  where 
  they 
  were 
  not 
  captured. 
  Fortunately 
  these 
  little 
  pests 
  are 
  less 
  preva- 
  

   lent 
  in 
  the 
  open 
  country 
  of 
  the 
  north 
  than 
  in 
  the 
  forest 
  region 
  of 
  Ashanti. 
  Culicoides 
  

   grahami, 
  Aust., 
  which 
  is 
  the 
  commonest 
  species 
  in 
  Ashanti, 
  is 
  rare 
  in 
  the 
  Northern 
  

   Territories 
  ; 
  it 
  appears 
  to 
  be 
  replaced 
  by 
  other 
  larger 
  species 
  with 
  less 
  conspicuously 
  

   spotted 
  wings 
  (Forcipomyia). 
  Larvae 
  and 
  pupae 
  of 
  Forcipomyia 
  ingrami, 
  Cart., 
  

   were 
  found 
  in 
  the 
  moist 
  debris 
  scraped 
  from 
  the 
  " 
  rot 
  " 
  holes 
  in 
  a 
  flamboyant 
  tree 
  

   at 
  Gambaga. 
  

  

  With 
  reference 
  to 
  the 
  greater 
  prevalence 
  of 
  8. 
  fasciata 
  throughout 
  the 
  Northern 
  

   Territories 
  during 
  and 
  shortly 
  after 
  the 
  close 
  of 
  the 
  wet 
  season, 
  attention 
  may 
  be 
  

   directed 
  to 
  the 
  fact 
  that 
  all 
  recent 
  cases 
  of 
  yellow 
  fever 
  amongst 
  Europeans 
  resident
