  may 
  be 
  distinguished 
  from 
  all 
  others 
  known 
  to 
  me 
  by 
  the 
  

   black 
  marking 
  cf 
  the 
  veins 
  sub-apically. 
  The 
  conspicuous 
  

   black

  in 
  one 
  example 
  (the 
  $ 
  , 
  the 
  

   £ 
  being 
  without 
  its 
  abdomen) 
  may 
  also 
  prove 
  to 
  be 
  a 
  good 
  dis- 
  

   tinctive 
  feature.

  From 
  a 
  specimen 
  in 
  my 
  Collection, 
  received 
  from 
  Mr. 
  H. 
  

   Strecker. 
  

  

  This 
  beautiful 
  species 
  is 
  allied 
  to 
  C. 
  scitiscripta 
  Walk.,* 
  and 
  

   C. 
  multiscripta 
  Riley. 
  f 
  It 
  cannot 
  be 
  the 
  former, 
  which 
  it 
  

   more 
  nearly 
  resembles, 
  as 
  that 
  is 
  described 
  with 
  three 
  thoracic 
  

   bands, 
  the 
  fore-wings 
  with 
  an 
  ochraceous 
  tinge, 
  and 
  the 
  wings 
  

   [the 
  four] 
  with 
  black 
  marginal 
  dots. 
  In 
  a 
  pen-and-ink 
  sketch 
  

   of 
  the 
  typical 
  specimen 
  in 
  the 
  British 
  Museum, 
  kindly 
  sent 
  

   me 
  by 
  Mr. 
  Butler, 
  the 
  marginal 
  dots 
  of 
  the 
  secondaries 
  are 
  

   represented. 
  C. 
  Candida 
  is 
  the 
  only 
  species 
  of 
  the 
  genus 
  

   which 
  we 
  have 
  seen, 
  in 
  which 
  these 
  spots 
  are 
  absent 
  from 
  the 
  

   secondaries, 
  and 
  in 
  which 
  the 
  wings 
  are 
  entirely 
  white.
