  pillar 
  which 
  mines 
  in 
  blotches 
  the 
  leaves 
  of 
  the 
  nut,

  which 
  

   makes 
  a 
  ridge 
  on 
  the 
  epidermis 
  of 
  the 
  mined 
  part. 
  This 
  moth 
  

   may 
  vie 
  with 
  all 
  others 
  in 
  beauty, 
  its 
  anterior 
  wings 
  are 
  streaked 
  

   transversely 
  with 
  clouded 
  gold 
  and 
  shining 
  silver; 
  on 
  each 
  wing 
  

   are 
  six 
  or 
  seven 
  gold 
  stripes, 
  and 
  four 
  or 
  five 
  silvery." 
  

  

  Note. 
  — 
  As 
  the 
  larva 
  of 
  Lithocollel'is 
  Coryli, 
  Nicelli, 
  mines 
  the 
  

   upper 
  side 
  of 
  the 
  nut 
  leaf 
  in 
  blotches, 
  and 
  the 
  larvse 
  of 
  L.Nicellii, 
  

   the 
  underside, 
  and 
  Reaumur 
  does 
  not 
  mention 
  on 
  which 
  side 
  his 
  larva 
  

   fed, 
  it 
  would 
  have 
  been 
  impossible 
  to 
  identify 
  the 
  species 
  but 
  for 
  

   his 
  description 
  of 
  the 
  perfect 
  insect, 
  which, 
  though 
  none 
  of 
  the 
  

   best, 
  sufficiently 
  points 
  to 
  NiceUii 
  in 
  preference 
  to 
  Coryli 
  to 
  indi- 
  

   cate 
  that 
  as 
  the 
  species. 
  In 
  other 
  cases 
  I 
  have 
  omitted 
  to 
  refer 
  

   to 
  his 
  descriptions 
  of 
  the 
  perfect 
  insects, 
  as 
  in 
  few 
  instances 
  are 
  

   the 
  species 
  recognizable. 
  The 
  descriptions 
  were 
  probably 
  made, 
  

   as 
  Zeller 
  has 
  suggested, 
  from 
  specimens 
  which 
  had 
  been 
  allowed 
  

   to 
  die 
  in 
  boxes, 
  and 
  afterwards 
  injured 
  in 
  pinning. 
  

  

  " 
  Since 
  these 
  mining 
  larvse 
  are 
  able 
  to 
  spin, 
  as 
  they 
  make 
  

   cocoons, 
  we 
  need 
  no 
  longer 
  wonder 
  how 
  they 
  can 
  form 
  those 
  

   kinds 
  of 
  ridges, 
  those 
  folds 
  of 
  the 
  epidermis, 
  which 
  they 
  have 
  

   loosened, 
  and 
  under 
  which 
  they 
  lodge. 
  We 
  have 
  elsewhere 
  (Vol. 
  

   II. 
  Mem. 
  v.) 
  seen 
  the 
  proceedings 
  of 
  the 
  larvae 
  which 
  roll 
  and 
  

   fold 
  leaves 
  by 
  means 
  of 
  thread, 
  which 
  they 
  place 
  in 
  different 
  di- 
  

   rections, 
  and 
  then 
  load 
  with 
  the 
  weight 
  of 
  their 
  body 
  ; 
  let 
  us 
  

   suppose 
  a 
  similar 
  industry 
  in 
  these 
  miners, 
  and 
  this 
  is 
  all 
  that 
  is 
  

   necessary 
  on 
  their 
  part 
  to 
  cause 
  the 
  loosened 
  membrane 
  to 
  

   assume 
  these 
  folds. 
  It 
  is 
  true 
  that 
  in 
  these 
  folds, 
  among 
  those 
  

   which 
  only 
  form 
  a 
  simple 
  ridge 
  on 
  the 
  leaves 
  of 
  the 
  oak, 
  the 
  

   parts 
  approximate 
  far 
  more 
  closely 
  than 
  when 
  leaves 
  themselves 
  

   are 
  folded, 
  but 
  then 
  our 
  mining 
  insects 
  have 
  to 
  deal 
  with 
  a 
  mem- 
  

   brane 
  incomparably 
  finer 
  and 
  thinner 
  than 
  a 
  leaf. 
  They 
  spin 
  

   webs 
  on 
  the 
  interior 
  portion 
  of 
  their 
  cavity, 
  and 
  it 
  is 
  these 
  webs 
  

   which 
  force 
  the 
  membrane 
  to 
  bend. 
  Their 
  webs 
  are 
  so 
  fine 
  and 
  

   close 
  that 
  I 
  should 
  not 
  have 
  recognized 
  them 
  had 
  I 
  not 
  known 
  

   that 
  our 
  insects 
  must 
  have 
  made 
  them." 
  

  

  " 
  All 
  the 
  miners 
  which 
  mine 
  in 
  blotches 
  do 
  not, 
  however, 
  form 
  

   folds 
  in 
  the 
  membrane 
  which 
  covers 
  them. 
  M. 
  Vallisnieri 
  has 
  

   mentioned 
  a 
  larva 
  which 
  mines 
  galleries 
  in 
  the 
  rose 
  leaves 
  of 
  our 
  

   gardens." 
  

  

  Note. 
  — 
  The 
  gallery 
  miner 
  of 
  the 
  rose 
  leaves 
  in 
  our 
  gardens 
  is 
  a 
  

   Nepticula, 
  but 
  unfortunately 
  for 
  deciding 
  on 
  the 
  specific 
  name, 
  it 
  

   happens 
  that 
  two 
  species 
  feed 
  in 
  the 
  rose 
  leaves. 
  However, 
  that 
  

   which 
  seems 
  the 
  most 
  common 
  is 
  Nepticula 
  anomalella; 
  these 
  larvse, 
  

   when 
  full 
  grown, 
  emerge 
  from 
  their 
  galleries, 
  and 
  generally 
  form 
  

   their 
  yellowish-brown 
  cocoons 
  at 
  the 
  base 
  of 
  the 
  footstalk 
  of 
  the
