   beetles

  — 
  hard, 
  somewhat 
  hairy 
  insects, 
  of 
  slender 
  

   oval 
  form,

  peculiar 
  habit 
  of 
  springing 
  into 
  

   the 
  air 
  with 
  a 
  sudden 
  click 
  when 
  placed 
  upon 
  their 
  backs. 
  A

  laying 
  their 
  eggs 
  most 
  commonly 
  in 
  grass-lands 
  

   in 
  the 
  earth. 
  Of 
  their 
  subsequent 
  life 
  history 
  little 
  is 
  yet 
  definitely 
  

   known. 
  It 
  seems 
  certain 
  that 
  all 
  live 
  more 
  than 
  one

  common 
  

   impression 
  that 
  the 
  period 
  of 
  life 
  in 
  the 
  larval 
  stage 
  does 
  not 
  extend 
  much 
  

   beyond 
  two 
  years.

  infested

  especially

   grass-land,

   The 
  white 
  grubs 
  or 
  grub-worms 
  are 
  the 
  larvae 
  or 
  young 
  of 
  the 
  very 
  

   common 
  insects 
  usually 
  known 
  as 
  May-beetles 
  or 
  June-bugs, 
  and 
  of 
  

   another 
  group, 
  known 
  as 
  manure 
  beetles. 
  These 
  grubs 
  are 
  so 
  common 
  

   and 
  generally 
  recognized 
  that 
  the 
  accompanying 
  figures 
  will 
  serve 
  to 
  

   identify 
  them 
  without 
  further 
  description. 
  They 
  are 
  most 
  abundant 
  in 
  

   grass-lands 
  or 
  in 
  lands 
  recently 
  in 
  grass, 
  although 
  they 
  are 
  occasionally 
  

   bred 
  in 
  large 
  numbers 
  in 
  fields 
  of 
  corn. 
  They 
  do 
  serious 
  injury 
  to
