  with 
  a 
  transverse 
  band 
  on 
  each 
  segment, 
  formed 
  of 
  

   alternate 
  bands 
  of 
  black 
  and 
  yellow, 
  excepting 
  on 
  the 
  first 
  three, 
  where 
  the 
  

   black 
  band 
  is 
  interrupted 
  by 
  the 
  yellow 
  points 
  only 
  toward 
  the 
  spiracles

   whilst 
  on 
  the 
  back, 
  the 
  yellow

  Chrysalis. 
  Very 
  similar 
  in 
  size 
  and 
  shape 
  to 
  that 
  of 
  P. 
  Zolicaon, 
  but 
  differ- 
  

   ing 
  in 
  its 
  lighter 
  color, 
  and 
  the 
  absence 
  of 
  the 
  dark 
  shading 
  on 
  the 
  dorsal 
  and 
  

   lateral 
  regions. 
  

  

  The 
  perfect 
  insect 
  has 
  occurred 
  in 
  Marin 
  County, 
  and 
  a 
  fine 
  specimen 
  was 
  

   taken 
  some 
  years 
  ago 
  near 
  Oakland 
  by 
  Mr. 
  Jas. 
  Behrens 
  ; 
  so 
  that 
  the 
  larva 
  

   may 
  be 
  sought 
  for 
  in 
  these 
  localities. 
  

  

  Papilio 
  Eurymedon. 
  Boisd. 
  

  

  Larva. 
  Head 
  pale 
  brown, 
  with 
  a 
  fleshy 
  tinge. 
  Entire 
  upper 
  surface 
  of 
  

   body 
  pale 
  apple 
  green, 
  with 
  the 
  following 
  markings. 
  The 
  first 
  segment 
  has 
  its 
  

   anterior 
  margin 
  broadly 
  yellow. 
  The 
  third 
  segment 
  is 
  much 
  thickened, 
  with 
  its 
  

   posterior 
  margin 
  broadly 
  yellow, 
  surmounted 
  by 
  a 
  row 
  of 
  small 
  black 
  dots, 
  and 
  

   in 
  front 
  with 
  a 
  series 
  of 
  about 
  si.x 
  irregular 
  yellow 
  patches, 
  edged 
  with 
  black, 
  

   enclosing 
  a 
  black 
  spot 
  with 
  a 
  yellow 
  centre. 
  Between 
  the 
  third 
  and 
  fourth 
  

   segments 
  is 
  a 
  broad 
  black 
  band, 
  which 
  is 
  concealed 
  by 
  the 
  margins 
  of 
  the 
  seg- 
  

   ments 
  at 
  the 
  will 
  of 
  the 
  insect. 
  On 
  the 
  fifth 
  and 
  si.xth 
  segments 
  are 
  two 
  black- 
  

   ish 
  dots, 
  and 
  on 
  the 
  seventh, 
  eighth, 
  and 
  ninth 
  are 
  four 
  black 
  or 
  purplish 
  dots. 
  

   Feet, 
  prolegs, 
  and 
  entire 
  under 
  surface, 
  greenish 
  white. 
  Body 
  tapering 
  very 
  

   much 
  posteriorly 
  from 
  the 
  third 
  segment. 
  Retractile 
  horns 
  bright 
  orange. 
  

   When 
  irritated, 
  the 
  insect 
  draws 
  in 
  its 
  head, 
  folding 
  it 
  almost 
  so 
  as 
  to 
  be 
  con- 
  

   cealed 
  by 
  the 
  first 
  segment, 
  and 
  swelling 
  out 
  the 
  third 
  in 
  front, 
  it 
  presents 
  a 
  

   most 
  grotesque 
  appearance 
  : 
  the 
  horns 
  being 
  protruded, 
  and 
  the 
  curious 
  yellow 
  

   markings, 
  which 
  have 
  some 
  resemblance 
  in 
  form 
  to 
  a 
  pair 
  of 
  spectacles, 
  repre- 
  

   senting 
  eyes. 
  It 
  must 
  under 
  these 
  circumstances 
  be 
  a 
  very 
  formidable 
  looking 
  

   monster 
  to 
  its 
  insect 
  enemies. 
  

  

  Food 
  plant, 
  Frangida 
  californica. 
  

  

  Chrysalis. 
  Long, 
  tapering 
  very 
  much 
  toward 
  the 
  anal 
  extremity, 
  which 
  is 
  

   very 
  sharply 
  pointed. 
  Color, 
  pale 
  fawn 
  color, 
  with 
  dashes 
  of 
  black 
  and 
  brown 
  

   very 
  irregularly 
  scattered 
  over 
  the 
  entire 
  surface, 
  a 
  little 
  more 
  intense 
  and 
  con- 
  

   nected 
  at 
  the 
  sides. 
  The 
  protuberances 
  of 
  the 
  head 
  and 
  thorax 
  are 
  brown, 
  

   mottled 
  with 
  dirty 
  white, 
  and 
  the 
  seventh, 
  eighth, 
  and 
  ninth 
  segments 
  have 
  each 
  

   two 
  raised 
  black 
  dots. 
  The 
  spiracles, 
  which 
  are 
  distinctly 
  seen, 
  are 
  dark 
  

   brown. 
  The 
  under 
  side 
  is 
  marked 
  with 
  dashes 
  of 
  brown 
  and 
  black, 
  irregularly
