  PSEUDAPHYCUS 
  HERACUS, 
  new 
  species 
  

  

  This 
  species 
  is 
  very 
  similar 
  to 
  meritoritts, 
  new 
  species, 
  described 
  

   elsewhere 
  in 
  this 
  paper, 
  and 
  the 
  two 
  species 
  are 
  found 
  infesting 
  appar- 
  

   ently 
  the 
  same 
  species 
  of 
  mealybug 
  in 
  some 
  localities 
  in 
  Virginia. 
  

   It 
  differs 
  from 
  jrwritorius, 
  however, 
  by 
  having 
  the 
  segments 
  of 
  the 
  

   funicle 
  shorter 
  and 
  more 
  transverse, 
  by 
  having 
  the 
  club 
  somewhat 
  

   longer 
  than 
  the 
  entire 
  funicle, 
  and 
  by 
  having 
  the 
  anterior 
  ocellus 
  

   situated 
  distinctly 
  above 
  the 
  middle 
  of 
  frontovertex.
