  My 
  experimental 
  trial 
  of 
  my 
  new 
  method 
  of 
  destroying 
  

   Glossina 
  palpalis 
  so 
  far 
  promises 
  well. 
  I 
  knew 
  from 
  my 
  

   previous 
  work 
  that 
  the 
  maximum 
  effect 
  was 
  reached 
  about 
  

   2 
  months 
  after 
  the 
  erection 
  of 
  the 
  shelters. 
  They 
  have 
  been 
  

   going 
  three 
  weeks 
  now. 
  The 
  totals 
  obtained 
  for 
  the 
  three 
  

   weeks 
  from 
  Bulago 
  Island 
  (7 
  collecting 
  places) 
  are 
  48, 
  157, 
  

   260; 
  and 
  from 
  Kimmi 
  Island 
  (6 
  collecting 
  places) 
  104, 
  200, 
  

   313. 
  So 
  the 
  number 
  is 
  going 
  up 
  by 
  leaps 
  and 
  bounds 
  and 
  it 
  

   looks 
  as 
  if 
  I 
  should 
  get 
  a 
  couple 
  of 
  hundred 
  weekly 
  from 
  

   each 
  shelter, 
  which 
  is 
  what 
  I 
  expect 
  if 
  the 
  method 
  is 
  to 
  succeed. 
  

   The 
  interesting 
  thing 
  is 
  that 
  on 
  each 
  island 
  I 
  have 
  left 
  un- 
  

   touched 
  one 
  ideal 
  natural 
  collecting 
  spot 
  (a 
  tree 
  trunk) 
  — 
  and 
  

   my 
  shelters 
  are 
  just 
  as 
  attractive 
  judging 
  by 
  the 
  comparative 
  

   numbers 
  obtained. 
  So 
  I'm 
  feeling 
  quite 
  cock-a-hoop 
  ! 
  ! 
  

   The 
  fact 
  that 
  the 
  maximum 
  effect 
  is 
  not 
  reached 
  for 
  some 
  

   weeks 
  seems 
  to 
  show 
  that 
  the 
  2 
  fly 
  hunts 
  very 
  carefidly 
  all 
  

   over 
  tlie 
  island 
  until 
  she 
  is 
  satisfied 
  which 
  is 
  the 
  best 
  place 
  !

   FALLAX, 
  Br. 
  — 
  Prof. 
  Poulton 
  said 
  that 
  he 
  had 
  received 
  the 
  

   following 
  note 
  from 
  Mr. 
  C. 
  N. 
  Barker 
  who 
  had 
  written 
  from 
  

   Durban 
  on 
  March 
  7, 
  1919. 
  The 
  Locustid 
  referred 
  to 
  was 
  

   probably 
  /aHrta;, 
  Br., 
  and 
  was 
  certainly 
  the 
  species 
  spoken 
  of 
  

   by 
  Dr. 
  G. 
  A. 
  K. 
  Marshall 
  in 
  Trans. 
  Ent. 
  Soc, 
  1902, 
  pp. 
  535-6. 
  

   The 
  insect, 
  with 
  its 
  very 
  long 
  antennae, 
  was 
  shown 
  in 
  the 
  

   accompanying 
  Plate 
  XIX, 
  fig. 
  59, 
  together 
  with 
  Camponotine 
  

   ants 
  of 
  three 
  species 
  (figs. 
  53-56) 
  and 
  an 
  ant-mimicking 
  bug 
  

   (figs. 
  57, 
  58), 
  all 
  captured, 
  Feb. 
  17, 
  1901, 
  on 
  a 
  small 
  bushy 
  

   vetch 
  at 
  Salisbury, 
  Mashonaland. 
  Dr. 
  Marshall 
  stated 
  that 
  

   the 
  Locustid, 
  " 
  in 
  spite 
  of 
  its 
  long 
  antennae, 
  bears 
  a 
  very 
  

   strong 
  resemblance 
  to 
  an 
  ant 
  " 
  (p. 
  535). 
  The 
  fineness 
  of 
  the 
  

   antennae 
  was 
  such 
  that 
  they 
  were 
  probably 
  invisible 
  at 
  a 
  

   short 
  distance. 
  Mr. 
  Barker 
  wrote 
  : 
  — 
  

  

  " 
  I 
  came 
  across 
  lately 
  whilst 
  staying 
  at 
  Winkle 
  Spruit 
  

   some 
  of 
  those 
  curious 
  little 
  Locustids 
  {Mrymecophava 
  sp.) 
  (a 
  

   North 
  African 
  species 
  is 
  figured 
  by 
  Dr. 
  Sharp 
  in 
  " 
  Insecta," 
  

   Part 
  I, 
  p. 
  223), 
  which 
  mimic 
  ants. 
  The 
  illusion 
  is 
  wonderful
