  notch 
  in 
  the 
  outer 
  margin. 
  Their 
  color 
  is 
  a 
  yellowish 
  brown, 
  with 
  a 
  

   metallic 
  lustre* 
  and 
  several 
  dull-whitish 
  streaks 
  and 
  spots. 
  The 
  hind 
  

   wings 
  are 
  similar 
  in 
  color 
  to 
  the 
  anterior 
  pair, 
  and 
  are 
  divided 
  into 
  

   three 
  lobes; 
  the 
  lower 
  division 
  is 
  complete, 
  extending 
  to 
  the 
  base, 
  the 
  

   upper 
  one 
  not 
  more 
  than 
  two-thirds 
  of 
  the 
  distance. 
  The 
  outer 
  and 
  

   hind 
  margins 
  of 
  the 
  wings, 
  as 
  well 
  as 
  all 
  the 
  edges 
  of 
  their 
  lobes, 
  

   are 
  bordered 
  with 
  a 
  deep 
  whitish 
  fringe, 
  sprinkled 
  here 
  and 
  there 
  

   with 
  brown 
  ; 
  the 
  body 
  is 
  long 
  and 
  slender, 
  and 
  a 
  little 
  darker 
  than 
  the 
  

   wings. 
  The 
  antennae 
  are 
  moderately 
  long 
  and 
  thread-like, 
  nearly 
  black, 
  

   but 
  beautifully 
  dotted 
  with 
  white 
  throughout 
  their 
  whole 
  length. 
  The 
  

   legs 
  are 
  long, 
  banded 
  alternately 
  with 
  yellowish 
  brown 
  and 
  white, 
  the 
  

   hind 
  ones 
  ornamented 
  with 
  two 
  pairs 
  of 
  diverging 
  spines, 
  having 
  at 
  

   their 
  base 
  a 
  garter-like 
  tuft 
  of 
  long 
  brown 
  scales, 
  from 
  which 
  feature 
  

   the 
  moth 
  derives 
  its 
  name."

  The 
  Pupa. 
  

   The 
  greenish 
  or 
  yellowish 
  pupa 
  of 
  this 
  insect 
  has 
  a 
  very 
  peculiar 
  form. 
  

   It 
  may 
  be 
  found 
  hanging 
  from 
  the 
  leaves 
  or 
  bark 
  of 
  the 
  grape, 
  as 
  an 
  

   irregular, 
  ragged 
  looking 
  object 
  with 
  an 
  inclination 
  to 
  the 
  supporting 
  

   surface 
  of 
  about 
  40°, 
  The 
  head 
  is 
  obliquely 
  truncate, 
  from 
  which 
  the 
  

   body 
  tapers, 
  slightly 
  curving 
  dorsally 
  to 
  the 
  tip 
  (fig. 
  5, 
  PI, 
  IV). 
  It 
  is 
  ridged, 
  

   angulatcd, 
  and 
  with 
  numerous 
  projections 
  — 
  the 
  most 
  prominent 
  of 
  which 
  

   is 
  the 
  dorsal, 
  located 
  about 
  midway 
  of 
  its 
  length. 
  Dr. 
  Fitch 
  has 
  com- 
  

   pared 
  it 
  to 
  the 
  dead 
  fragments 
  of 
  a 
  little 
  scraggy 
  twig. 
  The 
  pupae 
  vary 
  

   considerably 
  in 
  color, 
  being 
  either 
  green 
  or 
  some 
  shade 
  of 
  brown. 
  It 
  is 
  

   said 
  that 
  the 
  green 
  ones 
  are 
  found 
  only 
  on 
  the 
  green 
  leaves 
  and 
  the 
  

   brown 
  on 
  the 
  brown 
  bark 
  of 
  the 
  twigs; 
  in 
  each 
  case 
  they 
  harmon- 
  

   ize 
  so 
  perfectly 
  with 
  their 
  surroundings 
  that 
  it 
  is 
  not 
  easy 
  to 
  detect 
  them 
  ; 
  

   and 
  such 
  was 
  found 
  to 
  be 
  the 
  rule 
  among 
  a 
  large 
  number 
  reared 
  re- 
  

   cently. 
  The 
  changing 
  of 
  the 
  numerous 
  larvae 
  to 
  this 
  state 
  under 
  such 
  

   protective 
  conditions, 
  has 
  frequently 
  led 
  to 
  the 
  statement 
  that 
  the 
  insect 
  

   had 
  suddenly 
  disappeared. 
  The 
  duration 
  of 
  the 
  pupa 
  state 
  is 
  usually 
  

   six 
  or 
  eight 
  days, 
  but 
  it 
  may 
  be 
  prolonged 
  to 
  fourteen 
  by 
  cold 
  or 
  other 
  

   unfavorable 
  conditions. 
  

  

  The 
  Larva. 
  

  

  In 
  the 
  early 
  spring 
  as 
  the 
  leaves 
  of 
  the 
  grape 
  begin 
  to 
  unfold, 
  here 
  

   and 
  there 
  some 
  of 
  them 
  may 
  be 
  seen 
  webbed 
  together. 
  Within 
  these 
  

   clusters 
  of 
  developing 
  leaves, 
  represented 
  in 
  figure 
  3, 
  PI. 
  IV, 
  the 
  greenish 
  

   white-haired 
  larvae 
  of 
  this 
  insect 
  may 
  be 
  found. 
  As 
  an 
  aid 
  in

   tion,

  description 
  by 
  Dr. 
  Fitch
