  feed 
  on 
  a 
  large 
  variety 
  of 
  forest 
  trees, 
  including 
  many 
  conifers,

   are

  a 
  single 
  example 
  on 
  the 
  beach 
  

   near 
  Sandy 
  Hook, 
  some 
  years 
  ago. 
  The 
  fact 
  that 
  it 
  has 
  not 
  been 
  

   taken 
  since 
  by 
  the 
  many 
  collectors 
  who 
  have 
  scoured 
  the 
  State 
  raises 
  

   a 
  doubt 
  as 
  to 
  the 
  correctness 
  of 
  the 
  identifications. 
  The 
  larva 
  is 
  

   reported 
  as 
  feeding 
  on 
  "Gleditschia."

  Reported 
  from 
  all 
  sections 
  of 
  the 
  State 
  in 
  July 
  and 
  

   August 
  and 
  sometimes 
  rather 
  common. 
  The 
  caterpillar 
  feeds 
  on 
  

   oak, 
  hazel

  A.

  Sm. 
  & 
  Abb. 
  Occurs 
  from 
  June 
  to 
  August 
  throughout 
  the 
  

   State. 
  The 
  larva 
  is 
  the 
  common 
  "oak-worm," 
  which 
  is 
  sometimes 
  

   locally 
  abundant 
  and 
  destructive.

  have 
  seen 
  acres 
  of 
  oak 
  scrub 
  

   almost 
  defoliated 
  in 
  South 
  Jersey, 
  and 
  occasionally 
  larger 
  trees 
  are 
  

   badly 
  eaten; 
  but 
  no 
  permanent 
  injury 
  is 
  caused, 
  and 
  the 
  natural 
  

   enemies 
  of 
  the 
  species 
  speedily 
  regain 
  control.
