   KEY 
  TO 
  ALL 
  SPECIES 
  OF 
  CRYPTANURA* 
  

  

  This 
  key 
  is 
  based 
  partly 
  on 
  specimens 
  and 
  is 
  partly 
  compiled 
  from 
  

   characters 
  gleaned 
  from 
  published 
  descriptions. 
  Of 
  necessity 
  it 
  de- 
  

   pends 
  very 
  largely 
  on 
  color 
  characters 
  and 
  is 
  purely 
  artificial.
