  Head 
  pale, 
  silvery 
  gray, 
  black 
  on 
  occiput. 
  Thora.x 
  with 
  the 
  tegulse 
  and 
  sides 
  

   gray 
  ; 
  disc 
  velvety 
  black, 
  uniting 
  with 
  the 
  black 
  on 
  upper 
  side 
  of 
  head, 
  and 
  

   forming, 
  when 
  viewed 
  from 
  above, 
  a 
  long, 
  triangular 
  patch 
  ; 
  centre 
  of 
  thorax 
  

   gray 
  at 
  the 
  base. 
  Abdomen 
  dark 
  gray, 
  sprinked 
  with 
  black, 
  with 
  narrow 
  black 
  

   dorsal 
  line. 
  The 
  five 
  basal 
  segments 
  are 
  equally 
  divided 
  into 
  black 
  and 
  white 
  

   demi-bands, 
  the 
  black 
  being 
  very 
  intense 
  and 
  glossy.

  surface 
  of 
  thorax 
  

   gray, 
  with 
  central 
  interrupted 
  black 
  line. 
  Antennae

   beneath. 
  Tibiae 
  grayish 
  brown, 
  with 
  tarsi

  Primaries, 
  fuscous 
  with 
  many 
  paler 
  waved 
  lines, 
  and 
  a 
  whitish 
  space 
  reach- 
  

   ing 
  from 
  the 
  base 
  over 
  half-way 
  along 
  the 
  costa, 
  but 
  not 
  extending 
  to 
  its 
  edo-e. 
  

   Besting 
  upon 
  this 
  pale 
  space 
  are 
  five 
  bent 
  black 
  lines 
  of 
  unequal 
  length, 
  and 
  a 
  

   bent 
  line 
  at 
  the 
  apex 
  reaching 
  to 
  the 
  tip. 
  Along 
  the 
  margin, 
  from 
  internal 
  angle 
  

   to 
  apex, 
  is 
  a 
  pale 
  submarginal 
  band, 
  very 
  faintly 
  dentate 
  externally, 
  running 
  

   parallel 
  with 
  the 
  margin 
  until 
  it 
  reaches 
  the 
  apex, 
  where 
  it 
  spreads 
  into 
  a 
  wider 
  

   space, 
  receiving 
  the 
  before-mentioned 
  bent 
  apical 
  line. 
  At 
  the 
  base 
  of 
  interior 
  

   margin 
  is 
  a 
  clouded 
  black 
  patch. 
  The 
  fringes 
  are 
  brownish 
  black, 
  dotted 
  on 
  

   their 
  edges 
  with 
  six 
  conspicuous 
  white 
  patches, 
  which 
  do 
  not, 
  however, 
  entirely 
  

   cross 
  the 
  fringe. 
  The 
  whole 
  of 
  the 
  fringe 
  on 
  the 
  interior 
  margin 
  is 
  brownish 
  

   black. 
  

  

  Secondaries, 
  black, 
  with 
  brownish 
  tinge 
  ; 
  a

  whitish 
  band 
  at 
  the 
  base 
  

   widest 
  posteriorly 
  ; 
  a 
  narrow 
  grayish-white 
  band 
  crossing 
  the 
  wing 
  obliquely, 
  

   almost 
  parallel 
  with 
  the 
  margin, 
  but 
  slightly 
  bent 
  a 
  little 
  behind 
  the 
  middle. 
  

   Fringes 
  white, 
  intersected 
  with 
  brown.

  This 
  beautiful 
  specimen 
  closely 
  resembles 
  Sp. 
  eremitus, 
  Walk., 
  of 
  the 
  Atlantic 
  

   States, 
  but 
  is 
  readily 
  known 
  by 
  its 
  more 
  brilliant 
  gray 
  coloring, 
  by 
  the 
  very 
  

   sharply 
  defined 
  demi-bands, 
  and 
  by 
  the 
  strongly 
  marked 
  whitish 
  submarginal 
  

   band 
  of 
  the 
  fore-wings.

  specimen. 
  

  

  Thorax 
  pale, 
  ashy 
  gray, 
  slightly 
  sprinkled 
  with 
  black 
  hairs, 
  and 
  with 
  a 
  well- 
  

   defined 
  triangular 
  black 
  mark, 
  the 
  vertex 
  of 
  which 
  rests 
  on 
  the 
  prothorax, 
  its
