  Introductory. 
  

  

  The 
  following 
  report 
  is 
  the 
  fifth 
  and 
  last 
  of 
  a 
  series 
  dealing 
  with 
  entomological 
  

   research 
  in 
  the 
  British 
  Possessions 
  in 
  West 
  Africa. 
  The 
  other 
  four 
  have 
  appeared 
  

   in 
  previous 
  issues 
  of 
  this 
  Bulletin, 
  and 
  in 
  them 
  the 
  aims 
  and 
  methods 
  adopted 
  

   have 
  been 
  stated 
  in 
  considerable 
  detail. 
  This 
  paper 
  deals 
  mainly 
  with 
  the 
  results 
  

   of 
  personal 
  observations 
  on 
  the 
  geographical 
  distribution 
  of 
  the 
  various 
  blood- 
  

   sucking 
  insects 
  in 
  the 
  Gold 
  Coast, 
  made 
  during 
  a 
  tour 
  in 
  that 
  country 
  from 
  

   November 
  1912 
  to 
  June 
  1913 
  ; 
  with 
  these 
  are 
  incorporated, 
  wherever 
  possible, 
  

   records 
  of 
  previous 
  workers 
  in 
  this 
  line, 
  and 
  consequently 
  the 
  report 
  may 
  be 
  taken 
  

   as 
  a 
  general 
  summary 
  of 
  entomological 
  work 
  accomplished 
  in 
  this 
  Colony. 
  

  

  Several 
  general 
  considerations 
  of 
  the 
  factors 
  which 
  influence 
  insect 
  distribution 
  

   are 
  here 
  discussed, 
  e.g., 
  a 
  chapter 
  has 
  been 
  added 
  on 
  the 
  geographical 
  position 
  of 
  

   the 
  Colony, 
  in 
  so 
  far 
  as 
  this 
  determines 
  the 
  species 
  of 
  blood-sucking 
  insects 
  found 
  ; 
  

   the 
  physical 
  configuration 
  also 
  calls 
  for 
  comment, 
  as 
  the 
  mountains 
  and 
  rivers 
  are 
  

   factors 
  of 
  great 
  importance 
  in 
  the 
  distribution 
  of 
  such 
  species 
  ; 
  the 
  nature 
  and 
  

   distribution 
  of 
  the 
  vegetation 
  also 
  influence 
  the 
  types 
  found 
  in 
  the 
  different 
  

   localities, 
  and 
  consequently 
  a 
  few 
  short 
  notes 
  on 
  this 
  aspect 
  have 
  been 
  added.
