  COERECTION. 
  

  

  Since 
  the 
  first 
  part 
  of 
  this 
  paper 
  has 
  gone 
  to 
  press, 
  I 
  

   find 
  that 
  I 
  have 
  overlooked 
  two 
  species 
  described 
  by 
  

   Mr. 
  P. 
  C. 
  T. 
  Snellen 
  :— 
  

  

  DiCHELIA, 
  Gn.

   Dichelia 
  alhardana,

  (Dichelia) 
  alhardana, 
  Snell.,

  v. 
  Ent., 
  

   XV., 
  108—9, 
  PL 
  VIII., 
  10. 
  (1872). 
  

  

  Lower 
  Guinea. 
  

  

  I 
  have 
  re-described 
  this 
  species 
  as 
  Conchylis 
  tricolor 
  

   (ante, 
  pp. 
  69 
  — 
  70), 
  having 
  mistaken 
  vein 
  3 
  of 
  the 
  fore 
  

   wings 
  for 
  vein 
  2. 
  It 
  is 
  not 
  a 
  Conchylis, 
  and 
  is 
  probably 
  

   rightly 
  referred 
  to 
  the 
  genus 
  Dichelia, 
  though 
  the 
  stalk 
  

   to 
  veins 
  7 
  and 
  8 
  of 
  the 
  fore 
  wings 
  is 
  shorter 
  than 
  in 
  the 
  

   typical 
  species. 
  Argyrotoxa 
  viridis, 
  Wlsm., 
  though 
  

   resembling 
  this 
  species 
  in 
  appearance, 
  has 
  these 
  veins 
  

   separate, 
  though 
  somewhat 
  approximate 
  at 
  their 
  bases.
