  An 
  ant, 
  Holenopain 
  uioleiita, 
  is 
  both 
  a 
  scavenger 
  and 
  a 
  pest, 
  as 
  it 
  

   preys 
  on 
  chinch-bug 
  eggs, 
  and 
  on 
  the 
  larvae 
  of 
  the 
  codling 
  moth, 
  

   but 
  it 
  also 
  feeds 
  on 
  saccharine 
  substances, 
  and 
  the 
  tender 
  leaves 
  of 
  

   corn.

  this

  a

  Nematode

  *The

  was 
  60C

  F 
  ; 
  it 
  was 
  found 
  necessary 
  to

  some 
  

   form 
  of 
  instrument, 
  which 
  would 
  indicate

  entirely 
  excluded. 
  A
