  be 
  found 
  the 
  latter 
  part 
  of 
  August 
  or 
  in 
  early 
  September 
  to 
  the 
  number 
  

   of 
  30-75 
  under 
  one 
  scale, 
  where 
  they 
  remain 
  dormant 
  till 
  the 
  following 
  

   spring. 
  It 
  is 
  stated 
  that 
  two 
  and 
  possibly 
  three 
  generations 
  may 
  develop 
  

   in 
  one 
  season 
  in 
  the

  Food 
  plants. 
  This 
  scale 
  insect 
  is 
  specially 
  abundant 
  in 
  New 
  York 
  

   on 
  apple, 
  pear, 
  Japan 
  quince 
  and 
  blackcap 
  raspberry 
  bushes. 
  Dr 
  How- 
  

   ard 
  found 
  it 
  so 
  numerous 
  on 
  mountain 
  ash 
  in 
  the 
  Catskill 
  mountains, 
  

   that 
  hardly 
  a 
  twig 
  or 
  branch 
  was 
  uninfested. 
  It 
  has 
  also 
  been 
  recorded 
  

   on 
  the 
  following 
  : 
  crab 
  apple, 
  peach, 
  quince, 
  black 
  cherry, 
  choke 
  cherry, 
  

   wild 
  red 
  cherry, 
  shad 
  bush, 
  cherry 
  currant, 
  wild 
  flowering 
  currant, 
  black 
  

   walnut 
  and 
  black 
  alder 
  (C

  a 
  alni

  The 
  identity 
  of 
  the 
  

   insect 
  on 
  all 
  these 
  food 
  plants 
  has 
  not 
  been 
  estabhshed 
  beyond 
  question. 
  

   I 
  have 
  since 
  learned 
  that 
  Mr 
  King 
  has 
  succeeded 
  in 
  bringing 
  the 
  list 
  up 
  

   to 
  23 
  food 
  plants 
  ; 
  so 
  this 
  species 
  can 
  be 
  classed 
  as 
  a 
  general 
  feeder.
