  Dr. 
  Lamborn's 
  observations 
  were 
  made 
  at 
  Kuala 
  Lumpur, 
  F.M.S., 
  between 
  

   April 
  1920 
  and 
  April 
  1921. 
  During 
  this 
  period 
  a 
  very 
  large 
  number 
  of 
  Anopheline 
  

   mosquitos 
  were 
  captured 
  and 
  examined, 
  26 
  of 
  which 
  were 
  found 
  to 
  be 
  attacked 
  by 
  the 
  

   Culicoides.

  No 
  specimen 
  of 
  the 
  Culicoides 
  was 
  found 
  on 
  a 
  Culicine 
  mosquito, 
  but 
  this 
  was 
  

   probably 
  owing 
  to 
  the 
  comparatively 
  small 
  number 
  of 
  these 
  insects 
  which 
  was 
  

   examined. 
  In 
  every 
  case 
  the 
  parasites 
  were 
  found 
  attached 
  to 
  some 
  portion 
  of 
  the 
  

   abdomen 
  (generally 
  on 
  the 
  sides 
  of 
  gorged 
  individuals) 
  of 
  female 
  Anopheles. 
  The 
  

   absence 
  of 
  parasites 
  on 
  the 
  males, 
  and 
  on 
  the 
  thorax 
  of 
  the 
  females, 
  shows 
  con- 
  

   clusively 
  that 
  the 
  object 
  of 
  the 
  parasite 
  was 
  to 
  obtain 
  the 
  ingested 
  blood, 
  rather 
  

   than 
  the 
  body-fluids 
  of 
  the 
  mosquito 
  itself, 
  though 
  Dr. 
  Lamborn 
  notes 
  that 
  in 
  one 
  

   or 
  two 
  cases 
  no 
  trace 
  of 
  blood 
  could 
  be 
  found 
  either 
  in 
  the 
  host 
  or 
  the 
  parasite. 
  

   In 
  other 
  instances 
  blood 
  was 
  present 
  in 
  both. 
  

  

  As 
  had 
  previously 
  been 
  noticed 
  by 
  Stanton, 
  the 
  parasites 
  were 
  not 
  at 
  all 
  easily 
  

   disturbed 
  while 
  at 
  their 
  meal, 
  some 
  remaining 
  attached 
  to 
  the 
  abdomen 
  of 
  the 
  host 
  

   even 
  after 
  the 
  pair 
  had 
  been 
  chloroformed. 
  " 
  These 
  insects 
  were 
  in 
  no 
  wise 
  discon- 
  

   certed," 
  says 
  Dr. 
  Lamborn, 
  " 
  even 
  by 
  the 
  frantic 
  endeavours 
  of 
  the 
  captured 
  

   Anophelines 
  to 
  escape." 
  Observations 
  snowed 
  that 
  the 
  parasites 
  were 
  either 
  attached
