  The 
  '"Rose-bug" 
  or 
  "Rose 
  chafer"; 
  common 
  

   throughout 
  the 
  State, 
  often 
  coming 
  in 
  such 
  hordes 
  as 
  to 
  destroy 
  the 
  

   blossoms 
  of 
  roses 
  and 
  other 
  plants 
  blooming 
  in 
  June, 
  and 
  in 
  vine- 
  

   yards 
  in 
  some 
  sections 
  utterly 
  destroying 
  the 
  grape 
  crop 
  by 
  eating 
  

   the 
  blossoms. 
  They 
  also 
  eat 
  into 
  a 
  variety 
  of 
  fruits, 
  including 
  apples 
  

   and 
  do 
  great 
  mischief 
  in 
  that 
  way. 
  The 
  larvae 
  feed 
  on 
  the 
  roots 
  

   of 
  grasses 
  and 
  other 
  vegetation 
  in 
  waste 
  land 
  and 
  are 
  beyond 
  reach 
  

   of 
  destructive 
  measures. 
  Practically, 
  spraying 
  plants 
  to 
  be 
  protected 
  

   with 
  heavy 
  doses 
  of 
  arsenate 
  of 
  lead 
  or 
  collecting 
  the 
  adult 
  beetles 
  

   as 
  they 
  come 
  on, 
  by 
  collectors 
  adapted 
  to 
  the 
  special 
  work, 
  are 
  our 
  

   only 
  resorts.
