  SPH/ERIDIUM

  S. 
  sea 
  rabaeo 
  ides 
  Linn. 
  Throughout 
  the 
  State, 
  IV-IX, 
  common 
  on 
  fresh 
  

   cow-dung. 
  This 
  is 
  a 
  European 
  species 
  that 
  was 
  introduced 
  into 
  the 
  

   more 
  northern 
  part 
  of 
  the 
  State 
  about 
  the 
  date 
  of 
  the 
  previous 
  edi- 
  

   tion 
  and 
  was 
  therefore 
  not 
  included. 
  Since 
  that 
  time 
  it 
  has 
  spread 
  

   to 
  all 
  sections 
  and 
  has 
  become 
  plentiful. 
  Fortunately 
  as 
  a 
  scavengei 
  

   it 
  is 
  not 
  a 
  harmful 
  species. 
  

  

  CERCYON 
  Leach. 
  

   The 
  species 
  of 
  this 
  genus 
  are 
  not 
  well 
  determined 
  in 
  collections. 
  It 
  is 
  

   quite 
  probable 
  that 
  we 
  have 
  more 
  species 
  than 
  are 
  listed, 
  and 
  that 
  some 
  

   of 
  those 
  listed 
  do 
  not 
  actually 
  occur 
  with 
  us. 
  Most 
  of 
  them 
  live 
  in 
  dung 
  

   or 
  other 
  decaying 
  and 
  fermenting 
  material.
