﻿REPORT 
  OF 
  THE 
  STATE 
  ENTOMOLOGIST 
  2iy 
  

  

  tinues 
  its 
  course 
  downward, 
  and 
  on 
  the 
  stalks 
  examined 
  could 
  usually 
  

   be 
  found 
  at 
  the 
  end 
  of 
  a 
  freshly 
  cut 
  channel 
  of 
  about 
  one-half 
  inch 
  in 
  

   length. 
  Tn 
  several 
  instances 
  a 
  small 
  opening 
  was 
  visible 
  in 
  the 
  petiole 
  

   through 
  which 
  the 
  larva 
  had 
  emerged 
  to 
  undergo 
  its 
  transformations 
  

   within 
  a 
  fold 
  of 
  a 
  shriveling 
  leaf, 
  or 
  possibly 
  among 
  the 
  leaves 
  on 
  the 
  

   ground. 
  

  

  Its 
  Habits 
  Compared 
  with 
  Those 
  of 
  Proteoteras 
  aesculana. 
  

  

  These 
  closely 
  allied 
  insects 
  have 
  different 
  habits 
  that 
  are 
  of 
  value 
  in 
  

   distinguishing 
  the 
  species. 
  S. 
  Claypoliana 
  bores 
  the 
  leaf-stalk 
  of 
  both 
  

   the 
  buckeye 
  and 
  maple 
  and 
  very 
  rarely 
  the 
  twigs 
  of 
  the 
  former. 
  It 
  is 
  

   also 
  known 
  to 
  feed 
  on 
  the 
  blossoms 
  of 
  the 
  buckeye. 
  The 
  larva 
  of 
  

   JP. 
  cesculana 
  bores 
  the 
  slender 
  terminal 
  twigs 
  of 
  both 
  these 
  trees 
  and 
  

   often 
  forms 
  a 
  sweUing 
  or 
  pseudo-g?ill 
  — 
  the 
  former 
  insect 
  never 
  produces 
  

   a 
  gall. 
  F. 
  cesculana 
  bores 
  the 
  petioles 
  and 
  terminal 
  twigs 
  for 
  a 
  distance 
  

   of 
  from 
  one-half 
  an 
  inch 
  to 
  two 
  inches, 
  and 
  lives 
  in 
  the 
  gall, 
  apparently 
  

   through 
  most 
  of 
  its 
  larval 
  existence. 
  It 
  feeds 
  also 
  on 
  the 
  winged 
  

   seeds 
  of 
  the 
  maple. 
  S. 
  Claypoliana, 
  on 
  the 
  contrary, 
  seldom 
  or 
  never 
  

   bores 
  along 
  the 
  leaf-stem 
  more 
  than 
  half 
  an 
  inch, 
  very 
  rarely 
  enters 
  

   the 
  terminal 
  twigs, 
  and 
  lives 
  in 
  the 
  rolled 
  up 
  leaf 
  after 
  the 
  first 
  two 
  or 
  

   three 
  days. 
  

  

  Remedies. 
  

  

  The 
  mining 
  within 
  the 
  leaf-stalk 
  by 
  this 
  insect 
  has 
  caused 
  many 
  leaves 
  

   of 
  the 
  buckeye 
  and 
  maple 
  to 
  fall 
  in 
  certain 
  localities, 
  yet 
  it 
  is 
  not 
  proba- 
  

   ble 
  that 
  it 
  will 
  multiply 
  and 
  spread 
  to 
  such 
  an 
  extent 
  as 
  to 
  become 
  a 
  

   serious 
  pest, 
  although 
  in 
  one 
  ot 
  the 
  maple 
  twigs 
  sent, 
  four 
  of 
  the 
  five 
  

   leaves 
  that 
  it 
  bore 
  contained 
  larvae 
  within 
  the 
  petioles. 
  

  

  Should 
  further 
  observations 
  show 
  that 
  many 
  of 
  the 
  fallen 
  leaves 
  carry 
  

   with 
  them 
  to 
  the 
  ground 
  the 
  infested 
  portion 
  of 
  the 
  petiole 
  or 
  the 
  insect 
  

   within 
  the 
  folds 
  of 
  the 
  leaf, 
  as 
  they 
  appear 
  to 
  do 
  in 
  some 
  instances, 
  then 
  

   it 
  would 
  be 
  of 
  service 
  to 
  collect 
  and 
  burn 
  the 
  leaves 
  as 
  soon 
  as 
  they 
  fall, 
  

   and 
  before 
  the 
  larva 
  has 
  left 
  them.
