  Genus 
  CAMPOPLEX 
  Gravenhorst 
  

  

  The 
  new 
  species 
  described 
  below 
  runs 
  in 
  Schmiedeknecht's 
  key 
  s 
  

   to 
  couplet 
  30 
  where 
  it 
  agrees 
  with 
  all 
  of 
  the 
  characters 
  assigned 
  to 
  

   Eulimneria 
  Schmiedeknecht 
  except 
  that 
  the 
  head 
  is 
  not 
  broad 
  behind 
  

   the 
  eyes. 
  Beyond 
  this 
  point 
  it 
  runs 
  to 
  IdecMhis 
  Foerster. 
  Both 
  

   Eulimneria 
  and 
  IdecMhis 
  I 
  consider 
  as 
  synonyms 
  of 
  Campoplex 
  

   Gravenhorst.
