  This 
  is 
  a 
  very 
  strong 
  indication 
  that 
  the 
  insect 
  is 
  native 
  to 
  the 
  district 
  and 
  has 
  gone 
  

   to 
  the 
  cultivated 
  cacao 
  from 
  the 
  related 
  wild 
  species. 
  

  

  Distribution 
  (fig.

  — 
  The 
  insect 
  was 
  found 
  in 
  the 
  following 
  localities, 
  which 
  are 
  

   all 
  on 
  or 
  near

  In 
  addition 
  to 
  the 
  above, 
  Mr. 
  J. 
  B. 
  Rorer, 
  then 
  Mycologist 
  to 
  the 
  Department 
  

   of 
  Agriculture 
  of 
  Trinidad, 
  reported 
  to 
  me 
  that 
  he 
  had 
  seen 
  similar 
  froth-masses 
  on 
  

   the 
  flower-stalks 
  of 
  cultivated 
  cacao 
  at 
  Machala, 
  Province 
  of 
  El 
  Oro 
  (Pacific 
  Coast), 
  

   Ecuador, 
  in 
  December 
  1918, 
  but 
  no 
  specimens 
  were 
  obtained 
  for 
  examination. 
  

  

  In 
  Panama 
  the 
  insect 
  was 
  only 
  seriously 
  abundant 
  on 
  a 
  few 
  acres 
  near 
  Changuinola, 
  

   and 
  its 
  present 
  status 
  is 
  that 
  of 
  a 
  potential 
  pest 
  which 
  should 
  be 
  carefully 
  watched 
  

   in 
  case 
  conditions 
  should 
  become 
  suitable 
  for 
  its 
  rapid 
  multiplication 
  and 
  spread.
