  cberry, 
  common 
  in 
  Nevada. 
  Those 
  found 
  by 
  Mr. 
  Eaves 
  changed 
  to 
  clirjsalis 
  

   late 
  in 
  April, 
  and 
  from 
  ten 
  specimens 
  presented 
  to 
  me, 
  I 
  was 
  fortunate 
  enough 
  

   to 
  raise 
  six 
  males 
  and 
  four 
  females, 
  all 
  in 
  perfect 
  condition. 
  They 
  emerged 
  from 
  

   the 
  27 
  ih 
  of 
  May 
  to 
  the 
  8th 
  of 
  June.

  Larva. 
  ''Average 
  fcngth 
  when 
  full 
  grown, 
  1.15 
  in. 
  Cylindrical, 
  with 
  the 
  

   middle 
  segments 
  largest. 
  Most 
  common 
  ground 
  color, 
  green, 
  verging 
  on 
  blue, 
  

   sometimes 
  clear 
  pale 
  blue, 
  and 
  at 
  others, 
  deep 
  indigo 
  or 
  purplish 
  blue. 
  Each 
  

   segment 
  has 
  six 
  transverse 
  wrinkles, 
  (of 
  which 
  the 
  first 
  and 
  fourth 
  are 
  somewhat 
  

   wider 
  than 
  the 
  others) 
  four 
  longitudinal 
  yellow 
  lines 
  equidistant 
  from 
  each 
  other, 
  

   and 
  each 
  interrupted 
  by 
  a 
  pale 
  blue 
  spot 
  on 
  the 
  before 
  mentioned 
  first 
  and 
  fourth 
  

   transverse 
  wrinkles. 
  There 
  are 
  traces 
  of 
  two 
  additional 
  longitudinal 
  lines 
  below, 
  

   one 
  on 
  each 
  side, 
  immediately 
  above 
  the 
  prolegs. 
  On 
  each 
  transverse 
  wrinkle 
  

   is 
  a 
  row 
  of 
  various 
  sized, 
  round, 
  black, 
  polisl?ed, 
  slightly 
  raised 
  piliferous 
  spots, 
  

   those 
  on 
  wrinkles 
  one 
  and 
  four 
  being 
  largest 
  and 
  most 
  regularly 
  situated. 
  The 
  hairs 
  

   arising 
  from 
  these 
  spots 
  are 
  stiff 
  and 
  black. 
  Venter 
  rather 
  lighter 
  than 
  ground 
  

   color 
  above, 
  and 
  minutely 
  speckled 
  more 
  or 
  less 
  with 
  dull 
  black. 
  Head 
  same 
  

   color 
  as 
  the 
  body, 
  covered 
  with 
  black 
  piliferous 
  spots, 
  and 
  usually 
  with 
  a 
  yellow 
  

   or 
  orange 
  patch 
  on 
  each 
  side, 
  quite 
  variable. 
  The 
  black 
  piliferous 
  spots 
  fre- 
  

   quently 
  have 
  a 
  pale 
  blue 
  annulation 
  around 
  the 
  base, 
  especially 
  in 
  the 
  darker 
  

   specimens. 
  When 
  newly 
  batched, 
  the 
  larvae 
  are 
  of 
  an 
  uniform 
  orange 
  color 
  

   with 
  a 
  black 
  head, 
  but 
  become 
  dull 
  brown 
  before 
  the 
  first 
  moult, 
  though 
  the 
  

   longitudinal 
  stripes 
  and 
  black 
  spots 
  are 
  only 
  visible 
  after 
  that 
  moult 
  has 
  taken 
  

   place.

  Average 
  length, 
  0.65

  " 
  It 
  is 
  as 
  variable 
  in 
  depth 
  of 
  ground 
  color 
  as 
  the 
  larva. 
  The 
  general 
  color 
  is 
  

   light 
  bluish-gray, 
  more 
  or 
  less 
  intensely 
  speckled 
  with 
  black, 
  with 
  the 
  edges 
  and 
  

   prominence 
  marked 
  with 
  buff 
  or 
  flesh 
  color,

  The 
  caterpillar 
  of 
  this 
  common 
  species 
  feeds 
  on 
  various 
  cruciferous 
  plants, 
  

   and 
  may 
  be 
  sought 
  for 
  in 
  the 
  San 
  Joaquin 
  and 
  other 
  valleys, 
  where 
  the 
  butterfly 
  

   occurs 
  in 
  great 
  abundance, 
  though 
  it 
  is 
  somewhat 
  periodical 
  in 
  its 
  appearance. 
  It 
  

   is 
  probable 
  that 
  it 
  will 
  one 
  day 
  become 
  a 
  serious 
  pest 
  to 
  our 
  market 
  gardener, 
  

   as 
  cabbages 
  and 
  other 
  allied 
  plants 
  suffer 
  largely 
  from 
  its 
  attacks.

  Larva. 
  Head 
  round, 
  green, 
  speckled 
  with 
  black. 
  Body 
  long, 
  slender, 
  dot- 
  

   ted 
  with 
  black 
  granules, 
  and 
  marked 
  with 
  three 
  lead-colored 
  stripes. 
  Between 
  

   these 
  are 
  two 
  yellow 
  stripes 
  of 
  similar 
  width. 
  The 
  lateral 
  lead-colored 
  ones 
  are 
  

   edged 
  below 
  with 
  white 
  shading 
  into 
  yellow. 
  Under 
  side, 
  bluish-green. 
  Feeds 
  

   on 
  crucifera3, 
  the 
  larva 
  attaining 
  its 
  growth 
  early 
  in 
  July, 
  and 
  changing 
  to 
  a 
  

   curiously-horned 
  chrysalis, 
  which 
  tapers 
  gradually 
  and 
  almost 
  equally 
  towards 
  

   each 
  extremity. 
  At 
  first 
  glance, 
  it 
  much 
  resembles 
  a 
  brown 
  and 
  curled-up 
  leaf. 
  

   The 
  perfect 
  insect 
  escapes 
  the 
  following 
  season."
