  indistinctly 
  blotched 
  with 
  white 
  toward 
  the 
  

   middle 
  of 
  the 
  costa 
  and 
  the 
  posterior 
  margin. 
  'J'he 
  velveiy 
  black 
  markings, 
  

   which 
  give 
  so 
  beauiiful 
  an 
  appearance 
  to 
  this 
  insect, 
  are 
  very 
  variable 
  in. 
  their 
  

   intensity 
  ; 
  but 
  the 
  following 
  may 
  be 
  regarded 
  as 
  tlieir 
  normal 
  form. 
  Central 
  

   fascia 
  much 
  waved 
  posteriorly, 
  in 
  its 
  middle 
  approaching 
  the 
  disc, 
  and 
  inclosing 
  

   a 
  clouded 
  patch 
  near 
  the 
  costa, 
  which 
  surrounds 
  a 
  deep 
  black 
  discal 
  spot. 
  An- 
  

   teriorly, 
  the 
  central 
  fascia 
  is 
  only 
  slightly 
  waved, 
  very 
  distinct 
  on 
  the 
  outer 
  

   edge, 
  but 
  shading 
  to 
  a 
  black 
  cloud 
  on 
  the 
  inner 
  margin. 
  At 
  the 
  ba^e 
  of 
  the 
  

   wing 
  are 
  four 
  more 
  or 
  less 
  waved 
  black 
  lines, 
  the 
  two 
  broad 
  ones 
  being 
  most 
  

   distinct, 
  and 
  the 
  others 
  broken 
  up 
  into 
  irregular 
  patches. 
  Near 
  the 
  posterior 
  

   margin 
  is 
  a 
  notched 
  line 
  of 
  black, 
  which 
  joins 
  the 
  central 
  fascia 
  on 
  the 
  interior 
  

   margin, 
  and 
  on 
  the 
  posterior 
  margin 
  itself, 
  is 
  a 
  row 
  of 
  nine 
  minute 
  angular 
  

   patches, 
  also 
  velvety 
  black. 
  Fringe

  Posterior 
  wings, 
  smoky 
  white, 
  clouded 
  toward 
  the 
  outer 
  margin, 
  which 
  has 
  

   occasionally 
  some 
  faint 
  black 
  lines 
  at 
  the 
  base 
  of 
  the 
  fringe.

  I 
  at 
  first 
  thought 
  that 
  this 
  insect 
  might 
  be 
  one 
  of 
  the 
  numerous 
  varieties 
  of 
  

   the 
  European 
  S. 
  Revaijana, 
  but 
  a 
  comparison 
  has 
  convinced 
  me 
  that 
  they 
  are 
  

   distinct. 
  The 
  present 
  species 
  may 
  be 
  known 
  by 
  its 
  beauiiful 
  pale 
  but 
  rich 
  sea 
  

   green 
  color, 
  by 
  the 
  distribution 
  of 
  the 
  n\arkings 
  of 
  the 
  thorax, 
  and 
  by 
  the 
  

   greater 
  width 
  and 
  more 
  rounded 
  apices 
  of 
  the 
  fore 
  wings. 
  It 
  does 
  not 
  appear 
  to 
  

   be 
  rare, 
  though 
  its 
  habit 
  of 
  sitting 
  in 
  close 
  proximiiy 
  to 
  lichens 
  resembling 
  it 
  

   in 
  color 
  renders 
  it 
  liable 
  to 
  be 
  overlooked.

  This
