  This

  agrees 
  with 
  MonelUa

  that 
  it 
  carries 
  its

   of 
  flight 
  horizontally 
  while 
  walking 
  and 
  in 
  repose,

  No 
  Thysanoptera 
  have 
  yet 
  been 
  described 
  from 
  the 
  Hawaiian 
  

   Islands; 
  a 
  large 
  number 
  were, 
  I 
  believe, 
  collected 
  by 
  Dr. 
  R.

   Perkins 
  for 
  the 
  Hawaiian 
  Exploration

  but 
  they 
  have 
  

   apparently 
  not 
  been 
  yet 
  worked 
  out.
