  attempted 
  repeatedly 
  to 
  get 
  hold 
  of 
  the 
  viscera 
  with 
  its 
  

   proboscis 
  but 
  was 
  obviously 
  too 
  frightened 
  of 
  the 
  ant 
  to 
  be 
  

   successful. 
  After 
  watching 
  it 
  for 
  some 
  little 
  time 
  I 
  took 
  it, 
  

   in 
  doing 
  which 
  I 
  disturbed 
  the 
  ants 
  ; 
  and 
  the 
  beetle, 
  freed 
  

   from 
  most 
  of 
  its 
  assailants, 
  escaped 
  into 
  a 
  fissure 
  in 
  the 
  ground, 
  

   where 
  I 
  was 
  unafele 
  to 
  secure 
  it. 
  

  

  " 
  The 
  next 
  day 
  I 
  again 
  saw 
  Bengalia 
  [2 
  ^ 
  of 
  same 
  sp.] 
  

   robbing 
  the 
  same 
  ants, 
  392a, 
  393a 
  [many 
  workers 
  of 
  same 
  sp.], 
  

   as 
  they 
  returned 
  food-laden 
  to 
  their 
  burrow, 
  and 
  farther 
  on 
  

   found 
  three 
  or 
  four 
  more 
  of 
  the 
  flies 
  [2 
  (^ 
  of 
  same 
  sp.] 
  at 
  rest 
  

   near 
  a 
  column 
  of 
  the 
  Ponerines, 
  3936 
  [three 
  workers 
  of 
  Lepto- 
  

   genys 
  pavesii, 
  Emery], 
  emerging 
  from 
  a 
  hole 
  at 
  the 
  base 
  of 
  a 
  

   dead 
  tree, 
  in 
  formation 
  as 
  for 
  a 
  marauding 
  expedition. 
  In 
  

   this 
  case 
  the 
  instincts 
  of 
  the 
  Diptera 
  were 
  evidently 
  much 
  at 
  

   fault, 
  for 
  they 
  had 
  failed 
  to 
  distinguish 
  between 
  the 
  out- 
  

   going 
  army 
  and 
  one 
  returning 
  laden 
  with 
  spoil, 
  and 
  from 
  

   time 
  to 
  time, 
  poised 
  over 
  the 
  ants, 
  occasionally 
  swooped 
  

   down 
  as 
  if 
  they 
  could 
  hardly 
  conceive 
  that 
  prey 
  might 
  be 
  

   entirely 
  absent. 
  

  

  " 
  Continuing 
  my 
  observations 
  on 
  13th 
  January, 
  I 
  saw 
  at 
  

   the 
  base 
  of 
  a 
  baobab 
  the 
  Camponotine, 
  394a 
  [^ 
  min. 
  of 
  C'ani- 
  

   fonotus 
  {Myrmoturha) 
  sp.,* 
  impossible 
  to 
  identify 
  without 
  ^ 
  

   maj.], 
  climbing 
  up 
  backwards 
  and 
  dragging 
  up 
  after 
  it 
  the 
  

   dead 
  and 
  fully 
  grown 
  larva 
  of 
  the 
  Pierine 
  butterfly 
  Cafopsilia 
  

   florella, 
  ¥., 
  held 
  head 
  down. 
  Near 
  by 
  was 
  a 
  Bengalia, 
  394a 
  

   [^ 
  of 
  same 
  sp.]. 
  Whenever 
  the 
  ant 
  had 
  got 
  a 
  little 
  distance 
  

   away, 
  the 
  fly 
  followed 
  but 
  did 
  nothing, 
  as 
  if 
  loth 
  to 
  let 
  it 
  get 
  

   out 
  of 
  sight 
  but 
  uncertain 
  what 
  action 
  to 
  take; 
  and 
  in 
  the 
  

   course 
  of 
  about 
  five 
  minutes 
  the 
  ant 
  had 
  dragged 
  its 
  prey 
  

   up 
  the 
  tree 
  for 
  about 
  a 
  couple 
  of 
  feet. 
  The 
  Bengalia 
  then 
  

   suddenly 
  made 
  up 
  its 
  mind, 
  for 
  it 
  ran 
  up, 
  seized 
  the 
  larva 
  

   just 
  behind 
  the 
  head 
  in 
  its 
  forelegs 
  so 
  strongly 
  as 
  markedly 
  

   to 
  constrict 
  it, 
  and 
  made 
  most 
  frantic 
  suctorial 
  efforts 
  with 
  

   its 
  proboscis, 
  deeply 
  depressing 
  the 
  surface 
  of 
  the 
  dorsum 
  

   but 
  without 
  puncturing 
  it. 
  The 
  ant 
  was 
  too 
  strong 
  for 
  the 
  

  

  * 
  This 
  Camponotus 
  is 
  superficially 
  extremely 
  like 
  the 
  Ponerine 
  ant 
  

   Leptogenys 
  stuhlmanni. 
  It 
  is 
  possible 
  that 
  the 
  likeness 
  has 
  been 
  in- 
  

   creased 
  by 
  the 
  shrinkage 
  of 
  the 
  former, 
  but 
  it 
  is 
  difficult 
  to 
  believe 
  that 
  

   no 
  bionomic 
  principle 
  is 
  at 
  Avork. 
  It 
  would 
  be 
  very 
  interesting 
  to 
  

   examine 
  a 
  long 
  series 
  of 
  the 
  apparent 
  mimic.
