  This 
  species 
  differs 
  from 
  Nigilgia 
  adjectella, 
  Wkr., 
  in 
  

   the 
  second 
  fascia 
  having 
  but 
  one 
  metalhc 
  Kne 
  or 
  bar 
  

   instead 
  of 
  two, 
  in 
  the 
  absence 
  of 
  a 
  metalhc 
  hne 
  from 
  this 
  

   fascia 
  to 
  the 
  apex, 
  and 
  in 
  its 
  paler 
  colour 
  and 
  white 
  

   hind 
  wings.

  I 
  am 
  unable 
  to 
  separate 
  Nigilgia 
  from 
  Phycodes, 
  Gn., 
  

   a 
  genus 
  which 
  has 
  hitherto 
  been 
  confined 
  to 
  the 
  Indian 
  

   region, 
  but 
  which 
  is 
  apparently 
  equally 
  well 
  represented 
  

   in 
  Africa. 
  Walker's 
  type 
  was 
  received 
  from 
  Sierra 
  

   Leone. 
  I 
  have 
  in 
  my 
  collection 
  a 
  specimen, 
  also 
  a 
  

   female, 
  received 
  from 
  Mr. 
  F. 
  J. 
  Jackson, 
  who 
  met 
  with 
  

   it 
  at 
  Tangani, 
  Kolumbi 
  Creek 
  (East 
  Africa), 
  in 
  August, 
  

   1885.
