of  the  prothorax  is  golden  green,  with  the  exception  of  two  dorsal  spots  of  velvety 
black..  The  tergum  of  the  rest  of  the  thorax  and  abdomen  is  also  black,  but  marked  by 
three  longitudinal  golden  green  lines,  one  on  each  side  of  a  medial  one.  'The.  pectus  of 
the  mesothorax  is  black,  marked  at  least  by  one  oblique  white /asda  on  each  side.  The 
wings  are  velvety  black,  with  an  undulated  rim,  the  hollows  of  which  are  more  or  less 
slightly  tipped  with  white. 
The  upper  side  of  the  upper  wings  has  eleven  golden  green  transverse  lines,  which  are 
narrowest  towards  the  posterior  angled  The  seventh  of  these  lines  from  the  humeral 
angle  is  bifid  towards  the  anterior  margin  of  the  wing ;  and  between  the  second  and 
third  line  on  the  same  anterior  margin  are  two  golden  green  linear  dots,  and  a  longer 
one  between  the  ninth  and  tenth. 
The  under  side  of  the  upper  wings  has  the  interior  margin  brown,  but  all  the  rest 
velvety  black,  with  transverse  lines  of  a  bluish  green  colour.  Of  these  the  first  six 
from  the  humeral  angle  are  parallel ;  and  the  seventh  line,  which  is  somewhat  bifid  at 
the  anterior  margin,  meets  at  the  anal  angle  of  the  wing  the  eighth  line,  which  is  trifid 
or  even  quadrifid  at  the  anterior  margin,  and  is  by  far  the  longest.  The  three  or  four 
apical  lines  are  filiform,  the  ninth  generally  meeting  the  tenth  at  the  anterior  margin 
of  the  wing. 
The  upper  side  of  the  under  wings  is  velvety  black,  with  a  longitudinal  broad  discal 
band  of  a  golden  green  colour,  reaching  from  nearly  the  middle  of  the  anterior  margin 
to  the  anal  angle,  and  which  is  only  interrupted  by  two  or  three  black  spots  towards  the 
anal  angle.  The  interior  margin,  fringed  with  blackish  down,  is  also  lined  by  a  broad 
obscure  green  fascia,  which  meets  the  former  band  towards  the  anal  angle,  and  which 
is  interrupted  by  four,  or  even  more,  black  transverse  spots  towards  the  same  angle. 
The  posterior  margin  has  at  least  eight  transverse  golden  green  abbreviated  lines,  of 
which  the  fourth  and  eighth  are  the  shortest,  and  the  fifth  is  the  longest.  The  tail  of 
the  wing  is  long,  tapering,  black,  with  the  central  line  bluish  green. 
The  under  side  of  the  under  wings  is  golden  green,  becoming  more  bluish  towards  the 
tail.  The  interior  margin  is  fringed  towards  the  scutellar  angle  with  a  cinereous  down, 
and  has  four  abbreviated  parallel  black  transverse  spots  towards  the  anal  angle.  The 
anterior  margin  has  eight  abbreviated  transverse  black  bands,  of  which  the  shortest  are 
the  first  and  sixth,  counting  from  the  humeral  angle,  and  the  longest  the  eighth,  while 
the  third  and  fourth,  the  seventh  and  eighth,  meet  each  other  towards  the  disc  of  the 
wing.  The  posterior  margin  has  two  black  bands,  of  which  the  superior  one  is  furcated 
towards  the  posterior  angle  of  the  wing  ;  and  four  or  five  large  black  spots  towards  the 
anal  angle,  which  sometimes  coalesce  into  two  bands,  of  which  the  upper  is  abbreviated. 
The  tail  is  bluish  green,  with  the  margins  black. 
'  For  the  technical  terras  expressing  the  limits  of  a  Lepidopterous  wing,  I  use  the  nomenclature  given  by 
Messrs.  Kirby  and  Spence,  Introduction,  vol.  iii.  p.  727.  PI.  xiv.
