  and 
  the 
  latter 
  emerges 
  as 
  an 
  adult 
  moth 
  (PI. 
  IV, 
  

   fig. 
  1). 
  These 
  moths 
  of 
  the 
  first 
  brood 
  deposit 
  their 
  eggs 
  on 
  the 
  

   now 
  nearly 
  full-grown 
  berries 
  (see 
  fig. 
  7). 
  These 
  second-brood 
  eggs 
  

   are 
  usually 
  more 
  numerous 
  than 
  those 
  of 
  the 
  first 
  brood, 
  if 
  the 
  

   infestation 
  is 
  at 
  all 
  serious. 
  They 
  are 
  deposited 
  upon 
  the 
  surface 
  

   of 
  the 
  fruit 
  and 
  are 
  quite 
  conspicuous 
  as 
  white 
  scale-like 
  spots 
  (see 
  

   fig. 
  7). 
  When 
  the 
  infestation

  the 
  berries

  Cluster 
  of 
  Concord 
  grapes

  which 
  many 
  second-brood 
  

   eggs 
  of 
  Ihe 
  grape-berry 
  moth 
  are 
  present. 
  The 
  white 
  spots 
  indi- 
  

   cate 
  the 
  appearance 
  and 
  position 
  of 
  the 
  eggs. 
  Eggs 
  with 
  black 
  

   centers

  parasitized. 
  (Original.) 
  

  

  in 
  the 
  cluster 
  may 
  l>e 
  attacked 
  and 
  the 
  fruit 
  rendered 
  worthless. 
  

   The 
  larva 
  feeds 
  upon 
  the 
  pulp 
  of 
  the 
  fruit 
  and 
  sometimes 
  attacks 
  

   the 
  seeds 
  before 
  these 
  commence 
  to 
  harden. 
  By 
  the 
  time 
  the 
  grape 
  

   crop 
  is 
  ready 
  to 
  harvest 
  it 
  is 
  not 
  unusual 
  to 
  find 
  large 
  numbers 
  of 
  

   clusters 
  injured 
  to 
  the 
  extent
