  regular 
  rows 
  radiating 
  from 
  the 
  apex. 
  They 
  are 
  deposited 
  

   singly 
  on 
  the 
  under 
  surface 
  of 
  leaves. 
  I 
  observed 
  a 
  female 
  

   ovipositing, 
  one 
  evening 
  just 
  before 
  it 
  was 
  too 
  dark 
  to 
  see 
  the 
  

   eggs. 
  She 
  was 
  fluttering 
  around 
  some 
  bean 
  vines, 
  and 
  would 
  

   occasionally 
  alight 
  but 
  an 
  instant 
  on 
  the 
  edge 
  of 
  a 
  leaf, 
  bending 
  

   her 
  abdomen 
  beneath 
  to 
  place 
  the 
  egg 
  on 
  the 
  under 
  surface 
  ; 
  then 
  

   she 
  would 
  fly 
  about 
  a 
  few 
  moments 
  and 
  go 
  to 
  another 
  leaf. 
  I 
  

   watched 
  her 
  several 
  minutes, 
  and 
  she 
  oviposited 
  at 
  the 
  rate 
  of 
  

   about 
  two 
  eggs 
  per 
  minute. 
  

  

  Some 
  of 
  the 
  eggs 
  hatched 
  in 
  six 
  days. 
  The 
  freshly 
  hatched 
  

   larvae 
  are 
  2 
  mm. 
  long, 
  green 
  with 
  black 
  hairs 
  situated 
  in 
  

   small 
  black 
  tubercles. 
  At 
  first 
  they 
  ate 
  small 
  patches 
  of 
  the 
  

   substance 
  of 
  the 
  leaf, 
  leaving 
  the 
  opposite 
  epidermis; 
  but 
  when 
  

   five 
  days 
  old 
  they 
  ate 
  small 
  holes 
  entirely 
  thru 
  the 
  leaf. 
  Larger 
  

   caterpillars 
  ate 
  larger 
  holes, 
  and 
  ate 
  the 
  leaves 
  from 
  the 
  margin 
  

   as 
  well. 
  

  

  There 
  is 
  very 
  little 
  change 
  in 
  the 
  larva 
  at 
  the 
  successive 
  

   molts, 
  except 
  in 
  size. 
  The 
  full-grown 
  larva 
  is 
  about 
  36 
  

   mm. 
  long; 
  bright 
  green, 
  with 
  a 
  white 
  line 
  just 
  above 
  the 
  line 
  of 
  

   spiracles, 
  and 
  several 
  faint, 
  crinkly, 
  white 
  lines 
  down 
  the 
  back, 
  

   often 
  a 
  black 
  spiracular 
  line; 
  tubercles 
  mostly 
  white, 
  except 
  a 
  

   row 
  just 
  above 
  the 
  spiracles 
  which 
  are 
  black 
  and 
  larger 
  than 
  the 
  

   others. 
  (Usually 
  all 
  tubercles 
  were 
  black 
  previous 
  to 
  the 
  last 
  

   molt). 
  Feet 
  often 
  black; 
  head 
  green, 
  with 
  black 
  dots 
  where 
  the 
  

   hairs 
  are 
  situated, 
  and 
  a 
  black 
  line 
  on 
  lateral 
  margins; 
  mandibles 
  

   blackish 
  on 
  tip 
  and 
  edges. 
  The 
  prolegs 
  are 
  situated 
  on 
  segments 
  

   9, 
  10 
  and 
  13, 
  and 
  the 
  caterpillar 
  crawls 
  by 
  a 
  looping 
  motion; 
  

   when 
  at 
  rest, 
  its 
  back 
  is 
  humped 
  up. 
  

  

  A 
  caterpillar 
  in 
  breeding 
  cage 
  obtained 
  its 
  growth 
  and 
  ready 
  

   to 
  pupate 
  in 
  twenty-three 
  days. 
  The 
  pupa 
  is 
  pale 
  green 
  with 
  a 
  

   broad 
  brown 
  streak 
  on 
  the 
  back, 
  darker 
  on 
  the 
  margins 
  of 
  the 
  

   segments, 
  the 
  whole 
  pupa 
  turning 
  brownish 
  a 
  little 
  before 
  the 
  

   adult 
  emerges 
  ; 
  wing 
  and 
  leg-cases 
  extend 
  just 
  a 
  little 
  beyond 
  the 
  

   posterior 
  margin 
  of 
  the 
  fourth 
  abdominal 
  segment; 
  cremaster 
  

   short, 
  with 
  several 
  tiny 
  brown 
  hooks 
  attaching 
  the 
  pupa 
  to 
  the 
  

   slight 
  white 
  silken 
  cocoon, 
  which 
  is 
  made 
  between 
  leaves 
  fastened 
  

   together, 
  or 
  in 
  the 
  fold 
  of 
  a 
  single 
  leaf; 
  length 
  of 
  pupa 
  19 
  mm., 
  

   width 
  4.5 
  mm. 
  The 
  pupal 
  period 
  is 
  eight 
  to 
  eleven 
  days. 
  

  

  Food 
  plants. 
  — 
  Caterpillars 
  of 
  this 
  species 
  are 
  quite 
  general 
  

   feeders. 
  I 
  have 
  found 
  them 
  feeding 
  upon 
  the 
  following 
  plants:
