  This 
  species 
  is 
  distinguished 
  from 
  all 
  its 
  congeners 
  by 
  its 
  

   minute, 
  almost 
  rudimentary 
  eyes 
  and 
  very 
  long 
  slender 
  

   antennae.

  This 
  large 
  and 
  very 
  distinct 
  species 
  has, 
  owing 
  to 
  the 
  

   parallel 
  lines 
  on 
  its 
  thorax, 
  been 
  confounded 
  with 
  Pt. 
  a,ffine, 
  

   Ericlis., 
  but, 
  with 
  the 
  exception 
  of 
  the 
  thoracic 
  lines, 
  differs 
  

   entirely 
  from 
  that 
  species 
  in 
  size, 
  form, 
  colour, 
  and 
  sculpture. 
  

   It 
  appears 
  to 
  be 
  very 
  rare. 
  I 
  found 
  it 
  in 
  Wicken 
  Fen, 
  Cam- 
  

   bridgeshire, 
  but 
  have 
  met 
  with 
  it 
  in 
  only 
  two 
  continental 
  

   collections 
  ; 
  in 
  both 
  of 
  these 
  it 
  was 
  labelled 
  u 
  Pt. 
  ajfine."
