  almost 
  circular 
  in

  Primaries, 
  wholly 
  pale 
  gray, 
  with 
  narrow 
  black 
  longitudinal 
  lines, 
  only 
  

   slightly 
  bent, 
  the 
  two 
  largest 
  resting 
  on 
  the 
  centre 
  of 
  the 
  median

  Along 
  

   the 
  posterior 
  margin 
  is 
  a 
  whitish, 
  irregular, 
  submarginal 
  band, 
  not 
  reaching

  angle.

  undulating 
  whitish 
  bands, 
  the 
  outer 
  

   one 
  not 
  quite 
  reaching 
  to 
  the 
  apex.

  Taken 
  on 
  the 
  wing, 
  about 
  flowers 
  of 
  California 
  Laurel 
  [Oreodaphne 
  Califor- 
  

   nica), 
  near 
  St. 
  Helena, 
  Napa 
  County, 
  in 
  June, 
  1872. 
  A 
  strongly 
  marked 
  spe- 
  

   cies, 
  readily 
  distinguished 
  by 
  its 
  pale 
  fore-wings, 
  and 
  by 
  the 
  triangular 
  mark 
  of 
  

   the 
  thorax. 
  The 
  head 
  was, 
  unfortunately, 
  broken 
  from 
  my 
  unique 
  specimen 
  

   before 
  it 
  reached 
  my 
  hands.

  I 
  had 
  the 
  good 
  fortune 
  to 
  take 
  a 
  fine 
  $ 
  of 
  this 
  rare 
  species 
  in 
  Bear 
  Valley, 
  in 
  

   June, 
  1872. 
  It 
  was 
  hovering 
  at 
  mid-day 
  over 
  a 
  pool 
  of 
  water, 
  darting 
  down 
  

   occasionally 
  to 
  drink. 
  The 
  specimen 
  from 
  which 
  Dr. 
  Boisduval 
  made 
  his 
  de- 
  

   scription 
  was 
  captured 
  by 
  the 
  late 
  M. 
  Lorquin, 
  at 
  Grass 
  Valley, 
  resting 
  on 
  the 
  

   bark 
  of 
  a 
  Eedwood 
  tree, 
  {Sequoia 
  sempervirens 
  — 
  Lamb.)
