  It 
  may 
  be 
  distinguished 
  from 
  P. 
  cesculana 
  by 
  the 
  following 
  characters, 
  

  

  according 
  to 
  its 
  describer 
  : 
  

  

  Claypoliana 
  lacks 
  the 
  notch 
  in 
  posterior 
  borders 
  of 
  primaries, 
  the 
  tufts 
  

   of 
  raised 
  scales 
  on 
  the 
  discs 
  of 
  same, 
  and 
  the 
  peculiar 
  tuft 
  or 
  pencil 
  of 
  

   hairs 
  on 
  the 
  upper 
  surface 
  of 
  secondaries 
  in 
  the 
  male, 
  between 
  the 
  

   margin 
  and 
  the 
  costal 
  vein. 
  It 
  is 
  a 
  shorter, 
  broader- 
  winged 
  species; 
  

   the 
  ocellate 
  spot 
  is 
  less 
  distinctly 
  relieve'd, 
  the 
  median 
  oblique 
  band 
  more 
  

   broken, 
  the 
  basal-costal 
  portion 
  paler 
  and 
  contrasted 
  along 
  the 
  median 
  

   vein 
  with 
  a 
  dark 
  shade 
  which 
  may 
  be 
  almost 
  black, 
  and 
  which 
  broadens 
  

   posteriorly 
  till 
  near 
  the 
  middle 
  of 
  wing, 
  where 
  it 
  is 
  abruptly 
  relieved 
  by 
  

   a 
  pale 
  space 
  obliquing 
  basally. 
  

  

  Description 
  of 
  Several 
  Stages. 
  

  

  The 
  moth 
  has 
  been 
  characterized 
  briefly 
  by 
  Prof. 
  Clay 
  pole 
  as 
  follows 
  : 
  

   " 
  It 
  was 
  small, 
  with 
  a 
  peculiar 
  hopping 
  flight, 
  the 
  fore 
  wing 
  mottled 
  

   black 
  and 
  white, 
  and 
  the 
  hind 
  wing 
  more 
  uniform 
  in 
  color, 
  dusky, 
  and 
  

   slightly 
  spotted 
  with 
  black 
  near 
  the 
  tip." 
  

  

  The 
  light 
  red 
  pupa 
  was 
  inclosed 
  in 
  a 
  rolled 
  up 
  leaf 
  lined 
  inside 
  with 
  

   silk. 
  Eight 
  abdominal 
  segments 
  were 
  visible. 
  

  

  A 
  larva 
  examined 
  May 
  13th 
  was 
  two-fifths 
  of 
  an 
  inch 
  long 
  with 
  a 
  

   yellow 
  head 
  and 
  yellowish 
  body. 
  The 
  minute 
  granulations 
  of 
  the 
  skin 
  

   are 
  smooth, 
  — 
  not 
  pointed 
  as 
  in 
  P. 
  cesculana. 
  The 
  same 
  general 
  appear- 
  

   ance 
  was 
  retained 
  until 
  pupation, 
  except 
  that 
  it 
  became 
  a 
  little 
  darker. 
  

  

  Operations 
  and 
  Life-History. 
  

  

  In 
  the 
  leaf-stalks 
  of 
  the 
  buckeye, 
  ^sculus 
  glabra, 
  Prof. 
  Claypole 
  

   found 
  the 
  insect 
  during 
  the 
  early 
  part 
  of 
  May. 
  About 
  the 
  loth, 
  they 
  

   deserted 
  the 
  petioles 
  through 
  the 
  holes 
  by 
  which 
  they 
  had 
  entered, 
  

   and 
  betook 
  themselves 
  to 
  the 
  fading 
  leaves. 
  Upon 
  the 
  dying 
  foliage 
  

   they 
  completed 
  their 
  growth 
  naturally 
  to 
  all 
  appearances. 
  This 
  food- 
  

   habit 
  is 
  apparently 
  normal, 
  as 
  no 
  nibbled 
  green 
  leaves 
  were 
  found 
  on 
  

   the 
  infested 
  trees 
  after 
  the 
  larvse 
  had 
  deserted 
  the 
  leaf-stalks. 
  Pupation 
  

   occurs 
  the 
  latter 
  part 
  of 
  May, 
  — 
  the 
  first 
  pupa 
  being 
  found 
  on 
  the 
  25th. 
  

   The 
  moth 
  appears 
  about 
  fifteen 
  days 
  later. 
  Prof. 
  Claypole 
  was 
  not 
  

   able 
  to 
  ascertain 
  the 
  place 
  and 
  manner 
  of 
  the 
  deposit 
  of 
  its 
  eggs, 
  the 
  

   number 
  of 
  broods, 
  or 
  the 
  form 
  in 
  which 
  it 
  hibernates. 
  

  

  The 
  work 
  of 
  this 
  insect 
  in 
  the 
  maple 
  leaves 
  coincides 
  closely 
  with 
  that 
  

   in 
  the 
  buckeye. 
  The 
  egg 
  of 
  the 
  parent 
  moth 
  appears 
  to 
  be 
  placed 
  at 
  

   the 
  base 
  of 
  the 
  leaf, 
  — 
  perhaps 
  at 
  the 
  divarication 
  of 
  the 
  ribs. 
  As 
  the 
  

   young 
  larva 
  tunnels 
  the 
  petiole, 
  the 
  portion 
  traversed 
  by 
  it 
  shrivels, 
  black- 
  

   ens, 
  dries, 
  and 
  is 
  broken 
  off 
  by 
  the 
  weight 
  of 
  the 
  leaf
