   The 
  species 
  of 
  this 
  world-wide 
  genus 
  are 
  difficult 
  to 
  

   separate 
  owing

  their 
  extreme 
  similarity 
  in 
  colour, 
  

   structure, 
  and 
  sculpture. 
  The 
  species 
  here 
  described 
  fall 
  

   into 
  two 
  clearly-defined

  the 
  

   first 
  having 
  especially 
  well 
  marked
