  This 
  is 
  the 
  "Sugar-Cane 
  Aphis," 
  which 
  is 
  found 
  in 
  Java 
  and 
  

   Hawaii, 
  wherever 
  cane 
  is 
  grown. 
  The 
  following 
  enemies 
  attack 
  

   it 
  here: 
  

  

  Diptera: 
  Xanthogramnia 
  grandicornis 
  and 
  Leucopis

  Coleoptera: 
  Coccinella 
  repanda 
  and 
  abdominalis; 
  Scymnus 
  

   note 
  sc 
  ens 
  and 
  vividus. 
  

  

  It 
  is 
  visited 
  and 
  milked 
  by 
  Pheidole 
  megacephala. 
  

  

  The 
  following

  it 
  in 
  Java:

  Zehntner 
  has 
  figured 
  the 
  Aphis, 
  its 
  metamorphoses 
  and 
  

   enemies.

  An 
  Aphis 
  sacchari 
  from 
  the 
  Antilles 
  was 
  mentioned 
  by 
  an 
  anon- 
  

   ymous 
  writer 
  in 
  1833 
  in 
  Loudoun's 
  Magazine 
  of 
  Natural 
  History, 
  VI, 
  407-9 
  

   (with 
  appendix 
  by 
  Westwood 
  409-13), 
  fig. 
  54, 
  and 
  it 
  might 
  be 
  thought 
  

   that 
  Zehntner's 
  name 
  was 
  invalid. 
  The 
  Grenadan 
  insect, 
  however, 
  was 
  

   not 
  described 
  and 
  was 
  confused 
  with 
  the 
  Asiracid 
  Stenocranus 
  saccharivora 
  

   (Westwood), 
  the 
  drawings 
  actually 
  being 
  those 
  of 
  the 
  latter. 
  I 
  think, 
  

   therefore, 
  that 
  Zehntner's 
  name 
  is 
  not 
  preoccupied 
  and 
  can 
  stand.
