  On 
  the 
  Identification 
  of 
  the 
  yet 
  undetermined 
  Species 
  

   of 
  Microlepidoptera, 
  mentioned

  Memoires" 
  of

  The 
  Memoirs 
  of 
  Reaumur 
  and 
  De 
  Geer 
  contain 
  a 
  fund 
  of 
  useful 
  

   information 
  respecting 
  the 
  food, 
  times 
  of 
  appearance, 
  and 
  habits 
  

   of 
  insects, 
  but 
  as 
  in 
  neither 
  work 
  the 
  species 
  bear 
  scientific 
  names, 
  

   an 
  unassisted 
  reader 
  is 
  rather 
  doubtful 
  what 
  particular 
  species 
  are 
  

   alluded 
  to. 
  The 
  determination 
  of 
  such 
  species 
  of 
  Tineidce 
  as 
  our 
  

   present 
  knowledge 
  enables 
  us 
  to 
  make 
  will 
  therefore 
  be 
  interest- 
  

   ing 
  to 
  the 
  Micro- 
  Lepidopterist 
  of 
  the 
  present 
  day, 
  though 
  many 
  

   species 
  will 
  still 
  remain 
  unrecognized. 
  

  

  The 
  progress 
  that 
  has 
  been 
  made 
  in 
  the 
  investigation 
  of 
  these 
  

   small 
  tribes, 
  since 
  the 
  publication 
  in 
  the 
  " 
  Isis/' 
  1838, 
  of 
  Zeller's 
  

   elaborate 
  review 
  of 
  the 
  Lepidoptera 
  mentioned 
  by 
  Reaumur, 
  en- 
  

   ables 
  us 
  to 
  correct 
  many 
  errors 
  into 
  which 
  he 
  fell 
  from 
  the 
  then 
  

   deficient 
  state 
  of 
  knowledge. 
  

  

  In 
  order 
  to 
  make 
  fully 
  intelligible 
  the 
  following 
  notes 
  on 
  Reau- 
  

   mur's 
  observations 
  on 
  Lepidopterous 
  larvae 
  mining 
  in 
  leaves 
  of 
  

   plants, 
  it 
  was 
  necessary 
  to 
  translate 
  the 
  whole 
  of 
  those 
  which 
  

   occur 
  in 
  his 
  first 
  memoir 
  of 
  the 
  third 
  volume. 
  The 
  accuracy 
  of 
  

   these 
  notices, 
  and 
  the 
  fact 
  that 
  they 
  are 
  nearly 
  unknown 
  to 
  English 
  

   collectors, 
  would 
  be 
  additional 
  reasons, 
  if 
  any 
  were 
  required, 
  for 
  

   occupying 
  therewith 
  so 
  much 
  valuable 
  space. 
  

  

  Special 
  reasons 
  are 
  given, 
  in 
  some 
  instances, 
  for 
  coming 
  to 
  

   a 
  conclusion 
  different 
  from 
  that 
  at 
  which 
  Zeller 
  arrived, 
  in 
  1838. 
  

  

  Zeller's 
  Memoir 
  was 
  the 
  result 
  of 
  an 
  offer 
  by 
  the 
  " 
  Isis 
  von 
  

   Oken" 
  of 
  a 
  prize 
  for 
  the 
  best 
  discriminative 
  essay 
  on 
  the 
  subject 
  

   of 
  the 
  Lepidopterous 
  insects 
  in 
  Reaumur's 
  works 
  ; 
  of 
  those 
  sub- 
  

   mitted 
  in 
  competition, 
  it 
  obtained 
  the 
  first 
  place 
  ; 
  and 
  it 
  is 
  very 
  

   desirable 
  to 
  follow 
  up, 
  from 
  time 
  to 
  time, 
  as 
  our 
  knowledge 
  in- 
  

   creases, 
  a 
  work 
  so 
  well 
  begun. 
  

  

  The 
  idea 
  of 
  so 
  doing 
  is 
  due 
  to 
  Mr. 
  Stainton, 
  who 
  also 
  has 
  fur- 
  

   nished 
  rough 
  notes 
  of 
  the 
  following 
  matter, 
  which 
  his 
  present 
  

   avocations 
  have 
  not 
  left 
  time 
  for 
  him 
  to 
  put 
  into 
  form, 
  a 
  work 
  I 
  

   have 
  endeavoured 
  to 
  do, 
  at 
  his 
  request, 
  adding 
  here 
  and 
  there 
  a 
  

   few 
  remarks.
