  FAMILY 
  COCCID^. 
  

  

  Our 
  species 
  of 
  this 
  family 
  have 
  not 
  as 
  yet 
  been 
  investigated 
  in 
  

   their 
  living 
  state. 
  The 
  dried 
  shield-like 
  bodies 
  of 
  the 
  dead 
  fe- 
  

   males 
  have 
  been 
  met 
  with 
  on 
  several 
  of 
  our 
  indigenous 
  trees. 
  In 
  

   addition 
  to 
  the 
  species 
  so 
  abundant 
  upon 
  the 
  apple-tree, 
  and 
  cur- 
  

   rently 
  regarded 
  as 
  the
