  the 
  hind 
  wings, 
  the 
  apex 
  rounded 
  (rarely 
  subacute), 
  and 
  

   the 
  hind 
  margin 
  either 
  regularly 
  rounded 
  or 
  convex. 
  

   The 
  hind 
  wings 
  are 
  regularly 
  rounded, 
  and 
  more 
  dis- 
  

   tinctly 
  sinuated 
  than 
  the 
  fore 
  wings, 
  and 
  the 
  fringes 
  

   are 
  entire 
  or 
  very 
  slightly 
  sinuated, 
  and 
  rather 
  long 
  for 
  

   moths 
  of 
  comparatively 
  large 
  size. 
  

  

  Although 
  the 
  species 
  are 
  numerous 
  and 
  handsome, 
  

   their 
  colours 
  and 
  pattern 
  are 
  rather 
  uniform. 
  The 
  fore 
  

   wings 
  are 
  always 
  black, 
  with 
  pale 
  yellow, 
  or 
  more 
  rarely, 
  

   white 
  spots, 
  those 
  nearest 
  the 
  hind 
  margin 
  often 
  more 
  

   or 
  less 
  connected, 
  and 
  sometimes 
  coalescing 
  (except 
  the 
  

   spot 
  near 
  the 
  hinder 
  angle) 
  into 
  one 
  continuous 
  band 
  or 
  

   blotch. 
  The 
  hind 
  wings 
  are 
  usually 
  of 
  the 
  bright 
  

   crimson 
  colour 
  so 
  common 
  among 
  African 
  Lepidoptera 
  

   (which 
  is 
  liable 
  to 
  fade 
  to 
  a 
  yellowish 
  shade), 
  but 
  more 
  

   rarely 
  distinctly 
  yellow, 
  or 
  even 
  white 
  ; 
  and 
  the 
  fringes 
  

   here 
  also 
  are 
  sometimes 
  narrowly 
  edged 
  with 
  white, 
  or 
  

   other 
  pale 
  colour, 
  towards 
  the 
  upper 
  part 
  of 
  the 
  hind 
  

   margin. 
  The 
  abdomen 
  generally 
  extends 
  a 
  little 
  beyond 
  

   the 
  hind 
  wings, 
  and 
  is 
  nearly 
  always 
  yellow, 
  banded 
  

   with 
  black, 
  and 
  tufted 
  at 
  the 
  extremity 
  with 
  yellow, 
  or 
  — 
  

   in 
  the 
  males 
  — 
  usually 
  with 
  black. 
  

  

  The 
  spotting 
  of 
  the 
  fore 
  wings 
  is 
  very 
  uniform, 
  and 
  

   the 
  ordinary 
  spots 
  may 
  often 
  be 
  conveniently 
  referred 
  to 
  

   by 
  numbers. 
  There 
  is, 
  firstly, 
  a 
  spot 
  near 
  the 
  base 
  of 
  the 
  

   cell, 
  and 
  sometimes 
  continued 
  below 
  it 
  (No. 
  1) 
  ) 
  ; 
  a 
  second, 
  

   larger 
  and 
  more 
  square, 
  towards 
  the 
  end 
  of 
  the 
  cell 
  

   (No. 
  2) 
  ; 
  an 
  irregularly- 
  shaped 
  spot 
  below 
  No. 
  2, 
  often 
  

   filling 
  up 
  the 
  space 
  between 
  the 
  median 
  and 
  submedian 
  

   nervures 
  (No. 
  3) 
  ; 
  a 
  long 
  dash 
  on 
  the 
  inner 
  margin, 
  

   below 
  No. 
  1 
  (No. 
  4) 
  ; 
  the 
  apical 
  spot 
  (No. 
  5), 
  which 
  is 
  

   sometimes 
  broken 
  up 
  into 
  a 
  row 
  of 
  more 
  or 
  less 
  con- 
  

   tiguous 
  spots 
  (No. 
  5), 
  and 
  a 
  spot 
  towards 
  the 
  hinder 
  

   angle 
  (No. 
  6). 
  No. 
  4 
  is 
  sometimes 
  represented 
  by 
  an 
  

   irregular 
  mark 
  above, 
  instead 
  of 
  below, 
  the 
  submedian 
  

   nervure. 
  There 
  are 
  usually 
  some 
  obsolete 
  pale 
  blue 
  or 
  

   plumbeous 
  markings 
  formed 
  of 
  scattered 
  scales, 
  and 
  the 
  

   tibiae 
  are 
  nearly 
  always 
  more 
  or 
  less 
  yellow. 
  

  

  terms, 
  "primaries" 
  and 
  "secondaries," 
  to 
  the 
  wings 
  of 
  Lepi- 
  

   doptera, 
  because 
  tliey 
  are 
  in 
  imiversal 
  employment 
  in 
  another 
  

   branch 
  of 
  Zoology 
  in 
  a 
  totally 
  different 
  sense. 
  Such 
  an 
  application 
  

   of 
  well-known 
  scientific 
  terms 
  seems 
  to 
  me 
  to 
  be 
  both 
  unnecessary 
  

   and 
  inconvenient, 
  and 
  well 
  deserving 
  of 
  rejection 
  on 
  the 
  ground 
  of 
  

   pre 
  -occupation.'
