  The 
  present 
  study 
  is 
  the 
  result 
  of 
  an 
  attempt 
  to 
  classify 
  the 
  speciea 
  

   of 
  the 
  coleopterous 
  genus 
  Eupagoderes 
  in 
  my 
  own 
  collection. 
  Typical 
  

   and 
  nearly 
  typical 
  specimens 
  are 
  relatively 
  easy 
  to 
  place 
  by 
  the 
  use 
  of 
  

   existing 
  keys, 
  which 
  depend 
  upon 
  external 
  characters 
  entirely. 
  Many 
  

   specimens, 
  however, 
  vary 
  so 
  much 
  from 
  the 
  usual 
  condition 
  in 
  size, 
  

   shape, 
  and 
  vestiture 
  that 
  all 
  attempts 
  to 
  assign 
  them 
  to 
  their 
  proper 
  

   species 
  are 
  futile. 
  Other 
  specimens 
  fall 
  by 
  the 
  keys 
  into 
  species 
  to 
  

   which 
  they 
  do 
  not 
  belong, 
  because 
  of 
  the 
  student's 
  unfamiliarity 
  with 
  

   llie 
  amount 
  of 
  variation 
  allowable 
  in 
  certain 
  characters. 
  

  

  In 
  such 
  instances, 
  before 
  any 
  further 
  progress 
  can 
  be 
  made 
  in 
  

   identification, 
  it 
  is 
  necessary 
  to 
  go 
  beyond 
  the 
  external 
  characters 
  

  

  commonlv 
  employed 
  and 
  find, 
  if 
  possible, 
  at 
  least 
  one 
  definite 
  char-
