  First 
  stages. 
  — 
  ''When 
  newly 
  hatched, 
  I.71"™ 
  long, 
  dull 
  translucent 
  white 
  in 
  color, 
  

   with 
  very 
  minute 
  piliferous 
  points 
  giving 
  rise 
  to 
  pale 
  hairs. 
  Head 
  large 
  and 
  uni- 
  

   formly 
  brown-black. 
  Two 
  front 
  pair 
  of 
  prologs 
  atrophied 
  so 
  as 
  to 
  necessitate 
  loopirig 
  

   in 
  motion. 
  Drops 
  by 
  means 
  of 
  a 
  web. 
  In 
  the 
  second 
  stage 
  it 
  is 
  quite 
  active, 
  still 
  

   loops, 
  and 
  spins 
  a 
  web, 
  and 
  drops 
  at 
  least 
  disturbance. 
  Head 
  copal 
  yellow, 
  with 
  six 
  

   black 
  ocelli 
  (the 
  two 
  inferior 
  somewhat 
  separated 
  from 
  the 
  others), 
  the 
  brown 
  jaws 
  

   and 
  brown 
  marks 
  on 
  the 
  legs 
  conspicuous. 
  Color 
  of 
  body 
  yellowish-greeu, 
  darker 
  

   anteriorly, 
  the 
  venter 
  being 
  quite 
  pale. 
  The 
  lines 
  of 
  mature 
  larva 
  barely 
  indicated 
  

   in 
  faint 
  rose-brown, 
  the 
  most 
  conspicuous 
  being 
  the 
  broad 
  stigmatal, 
  a 
  narrower 
  one 
  

   above 
  it, 
  and 
  two 
  which 
  are 
  medio-dorsal. 
  In 
  the 
  better 
  marked 
  specimens, 
  the 
  body 
  

   above 
  the 
  pale 
  substigmatal 
  line 
  consists 
  of 
  8 
  dark 
  and 
  7 
  pale 
  lines, 
  the 
  middle 
  pale 
  

   line 
  medio-dorsal, 
  the 
  second 
  dark 
  one 
  from 
  it 
  most 
  faint 
  and 
  most 
  often 
  obsolete, 
  and 
  

   the 
  lower 
  or 
  stigmatal 
  one 
  broadest 
  and 
  most 
  conspicuous. 
  Black 
  piliferous 
  dots 
  dis- 
  

   tinct 
  and 
  normally 
  arranged, 
  i. 
  e. 
  : 
  on 
  the 
  middle 
  joints 
  4 
  trapezbidally 
  on 
  dorsum; 
  2 
  

   in 
  stignaatal 
  dark 
  line, 
  one 
  just 
  above, 
  the 
  other 
  just 
  behind 
  stigmata; 
  one 
  at 
  lower 
  

   edge 
  of 
  pale 
  substigmatal 
  line 
  near 
  the 
  middle 
  of 
  the 
  joint, 
  and 
  several 
  that 
  are 
  ven- 
  

   tral 
  : 
  the 
  dorsal 
  ones 
  on 
  joints 
  1 
  and 
  12 
  forming 
  a 
  reversed 
  trapezoid 
  to 
  those 
  on 
  mid- 
  

   dle 
  joints; 
  on 
  jt. 
  11 
  a 
  square, 
  and 
  on 
  jts. 
  2 
  and 
  3 
  a 
  transverse 
  line. 
  In 
  the 
  third 
  stage 
  

   there 
  is 
  little 
  change. 
  The 
  head 
  has 
  still 
  a 
  copal 
  yellow 
  aspect, 
  being 
  pale, 
  with 
  faint 
  

   yellowish-brown 
  mottlings; 
  the 
  ocelli 
  still 
  conspicuous. 
  The 
  body 
  is 
  more 
  decidedly 
  

   striped, 
  the 
  dark 
  stigmatal 
  and 
  pale 
  substigmatal 
  lines 
  more 
  strongly 
  relieved, 
  and 
  

   all 
  the 
  lines 
  approach 
  more 
  to 
  those 
  of 
  final 
  stage. 
  The 
  pale 
  hairs 
  from 
  piliferous 
  dots 
  

   are 
  still 
  quite 
  noticeable, 
  especially 
  before 
  and 
  behind, 
  and 
  the 
  dots 
  themselves 
  are 
  

   generally 
  relieved 
  by 
  a 
  pale 
  basal 
  annulus. 
  The 
  looping 
  habit 
  is 
  lost, 
  but 
  the 
  front 
  

   prologs 
  are 
  still 
  somewhat 
  the 
  smallest. 
  It 
  now 
  curls 
  round, 
  and 
  does 
  not 
  spin 
  in 
  

   dropping. 
  In 
  the 
  foiiriJi 
  stage 
  the 
  aspect 
  is 
  quite 
  changed, 
  the 
  general 
  color 
  being 
  

   dull, 
  dark 
  green. 
  The 
  head 
  has 
  the 
  mottlings 
  of 
  a 
  deeper 
  brown 
  and 
  the 
  character- 
  

   istic 
  brown 
  lines 
  appear. 
  The 
  second 
  pale 
  line 
  (from 
  above) 
  is 
  obsolete, 
  and 
  the 
  other 
  

   five 
  are 
  narrowed, 
  pure 
  white, 
  and 
  sharply 
  relieved 
  by 
  dark 
  shades. 
  The 
  prologs 
  are 
  

   of 
  nearly 
  equal 
  size; 
  the 
  cervical 
  shield 
  better 
  defined: 
  in 
  short, 
  except 
  in 
  the 
  lighter 
  

   substigmatal 
  stripe 
  and 
  more 
  greenish 
  color, 
  iiie 
  characters 
  of 
  the 
  more 
  normal, 
  ma- 
  

   ture 
  larva 
  obtain. 
  In 
  the 
  ff 
  tit 
  and 
  sixth 
  stages 
  the 
  changes 
  are 
  mainly 
  in 
  the 
  increasing 
  

   prevalence 
  of 
  the 
  brown 
  and 
  ferruginous 
  colors, 
  and 
  the 
  greater 
  relief 
  and 
  intensity 
  

   of 
  the 
  black, 
  especially 
  above 
  the 
  upper 
  white 
  lateral 
  line. 
  The 
  front 
  prologs 
  in 
  the 
  

   last 
  stage 
  are, 
  if 
  anything, 
  longer 
  than 
  the 
  hind 
  ones; 
  I 
  reproduce 
  herewith, 
  with 
  a 
  

   few 
  additions, 
  my 
  original 
  description 
  of 
  the 
  

  

  Full-grown 
  larva. 
  — 
  '* 
  General 
  color 
  dingy 
  black, 
  appearing 
  finely 
  mottled 
  and 
  speckled 
  

   under 
  a 
  lens, 
  with 
  the 
  piliferous 
  spots 
  placed 
  in 
  the 
  normal 
  position, 
  but 
  scarcely 
  visi- 
  

   ble, 
  though 
  the 
  soft 
  hairs 
  arising 
  from 
  them 
  are 
  easily 
  seen 
  with 
  the 
  lens. 
  Four 
  

   lateral 
  light 
  lines, 
  of 
  almost 
  equal 
  thickness, 
  at 
  about 
  equal 
  distance 
  from 
  each 
  other, 
  

   the 
  uppermost 
  two 
  white, 
  the 
  lowermost 
  two 
  yellow 
  ; 
  a 
  much 
  less 
  distinct 
  mediodorsal 
  

   white 
  line, 
  frequently 
  obsolete 
  in 
  middle 
  of 
  joints, 
  and 
  always 
  most 
  distinct 
  at 
  the 
  

   ■divisions 
  ; 
  a 
  jet-black 
  line 
  immediately 
  above 
  the 
  upper 
  lateral 
  white 
  one, 
  the 
  dorsum 
  

   near 
  it 
  thickly 
  mottled 
  with 
  dull 
  yellow, 
  but 
  becoming 
  darker 
  as 
  it 
  approaches 
  the 
  

   fine 
  dorsal 
  white 
  line, 
  along 
  each 
  side 
  of 
  which 
  it 
  is 
  perfectly 
  black. 
  Space 
  between 
  

   lateral 
  light 
  lines 
  1 
  and 
  2, 
  from 
  above, 
  dull 
  yellow 
  or 
  reddish, 
  the 
  white 
  lines 
  being 
  

   relieved 
  by 
  a 
  darker 
  edge 
  ; 
  that 
  between 
  lines 
  2 
  and 
  3 
  almost 
  black, 
  being 
  but 
  slightly 
  

   mottled 
  along 
  the 
  middle 
  ; 
  that 
  between 
  3 
  and 
  4 
  yellow, 
  mottled 
  with 
  pink 
  brown, 
  

   and 
  appearing 
  lighter 
  than 
  that 
  between 
  1 
  and 
  2. 
  Venter 
  greenish-glaucous, 
  mottled 
  

   and 
  speckled 
  with 
  neutral 
  color, 
  especially 
  near 
  the 
  edge 
  of 
  the 
  4th 
  lateral 
  line. 
  Legs 
  

   glossy 
  and 
  of 
  same 
  color 
  as 
  venter; 
  those 
  on 
  thoracic 
  joints 
  with 
  black 
  claws; 
  those 
  

   on 
  abdomen 
  with 
  a 
  large, 
  shiny, 
  black 
  spot 
  on 
  the 
  outside. 
  Stigmata 
  oval, 
  black, 
  and 
  

   placed 
  in 
  the 
  3d 
  lateral 
  light 
  line. 
  Head 
  highly 
  polished, 
  pale 
  grayish-yellow, 
  speckled
