  The

  cleared 
  in 
  potash, 
  so 
  that 
  it 
  is 
  possible 
  

   to 
  get 
  but 
  an 
  approximate 
  idea 
  of 
  the 
  coloration 
  ; 
  the 
  colour 
  

   of 
  the 
  antennae 
  is 
  taken 
  from 
  a 
  second 
  example 
  captured 
  by 
  

   Prof. 
  Sahlberg 
  at 
  Heluan, 
  This 
  example, 
  carded, 
  showed 
  

   a 
  pronounced 
  metallic 
  purplish 
  coloration, 
  but 
  I 
  do 
  not 
  think 
  

   it 
  was 
  natural.
