  lines 
  of 
  black, 
  arranged 
  triangularly, 
  the 
  side 
  of 
  the 
  triangle 
  joining 
  the 
  two 
  

   orange 
  spots, 
  and 
  the 
  apex 
  directed 
  towards 
  the 
  base 
  of 
  the 
  wing. 
  The 
  third 
  

   spot 
  is 
  small, 
  almost 
  square, 
  and 
  divided 
  by 
  a 
  black 
  line. 
  The 
  fourth 
  is 
  the 
  

   largest, 
  oblong, 
  joining 
  a 
  bent 
  orange 
  line, 
  which 
  rests 
  on 
  a 
  small 
  triangular 
  

   mark, 
  behind 
  which 
  is 
  a 
  straight 
  and 
  rather 
  narrow 
  orange 
  patch. 
  The 
  fifth 
  

   spot 
  is 
  the 
  smallest, 
  almost 
  triangular 
  in 
  form, 
  with 
  a 
  small 
  ovate 
  patch 
  beneath 
  

   it. 
  The 
  whole 
  of 
  these 
  orange 
  spots 
  are 
  narrowly 
  edged 
  with 
  black. 
  On 
  the 
  

   disc 
  is 
  a 
  small 
  ring, 
  formed 
  by 
  a 
  black 
  line, 
  and 
  two 
  others, 
  nearly 
  the 
  same 
  

   shape, 
  on 
  the 
  interior 
  margin.
