  put 
  among 
  the 
  well-coloured 
  ones. 
  The 
  ground 
  colour 
  is 
  a 
  yel- 
  

   lowish 
  white, 
  but 
  all 
  along 
  the 
  back 
  is 
  a 
  reddish-brown 
  stripe, 
  

   and 
  on 
  each 
  side 
  are 
  two 
  rows 
  of 
  spots, 
  redder 
  than 
  the 
  dorsal 
  

   stripe, 
  and 
  well 
  defined, 
  one 
  spot 
  being 
  placed 
  directly 
  above 
  the 
  

   other 
  on 
  each 
  segment." 
  

  

  Note. 
  — 
  Gelechia 
  ncev'iferella 
  is 
  here 
  alluded 
  to, 
  and 
  not 
  G. 
  Her- 
  

   mannella, 
  as 
  Zeller, 
  in 
  1838, 
  had 
  imagined. 
  Hermannella 
  makes 
  

   a 
  green 
  blotch, 
  afterwards 
  becoming 
  yellowish, 
  but 
  rK^viferella 
  

   an 
  extremely 
  white 
  and 
  transparent 
  one 
  ; 
  the 
  description 
  of 
  the 
  

   larva 
  agrees 
  well 
  with 
  that 
  of 
  ncev'iferella, 
  but 
  not, 
  as 
  Zeller 
  had 
  

   remarked, 
  with 
  that 
  of 
  G. 
  Hermannella. 
  

  

  " 
  The 
  place 
  at 
  which 
  a 
  gallery 
  miner 
  (just 
  emerged 
  from 
  the 
  

   egg) 
  has 
  entered 
  a 
  leaf 
  is 
  easy 
  to 
  recognize 
  ; 
  it 
  is 
  so 
  narrow 
  as 
  to 
  

   be 
  hardly 
  as 
  wide 
  as 
  the 
  finest 
  thread 
  ; 
  but 
  the 
  path 
  gradually 
  

   widens, 
  and 
  at 
  the 
  other 
  end 
  is 
  nearly 
  as 
  wide 
  as 
  a 
  narrow 
  riband 
  ; 
  

   for 
  by 
  degrees, 
  as 
  the 
  miner 
  excavates 
  and 
  opens 
  out 
  a 
  road 
  be- 
  

   fore 
  him, 
  he 
  eats 
  and 
  grows, 
  the 
  diameter 
  of 
  his 
  body 
  increases, 
  

   and 
  requires 
  a 
  wider 
  habitation. 
  If 
  we 
  take 
  a 
  leaf 
  mined 
  in 
  this 
  

   way, 
  and 
  hold 
  it 
  up 
  to 
  a 
  light, 
  or 
  better 
  still, 
  to 
  the 
  sun, 
  such 
  

   places: 
  being 
  transparent, 
  we 
  shall 
  not 
  fail 
  to 
  see 
  the 
  insect, 
  if 
  in- 
  

   deed 
  it 
  has 
  not 
  already 
  quitted 
  the 
  leaf; 
  and 
  its 
  head 
  will 
  be 
  

   always 
  at 
  the 
  broadest 
  end 
  of 
  the 
  gallery. 
  In 
  the 
  entire 
  space 
  

   which 
  it 
  has 
  previously 
  inhabited 
  (Ncplicula), 
  we 
  observe 
  little 
  

   black 
  grains, 
  which 
  are 
  nothing 
  but 
  the 
  excrement 
  it 
  has 
  made 
  on 
  

   its 
  road. 
  These 
  grains 
  are 
  placed 
  in 
  a 
  row 
  behind 
  one 
  another, 
  

   but 
  in 
  the 
  wider 
  galleries 
  there 
  are 
  several 
  rows 
  placed 
  side 
  by 
  

   side. 
  In 
  the 
  leaves 
  mined 
  in 
  blotches, 
  the 
  excrements 
  are 
  all 
  col- 
  

   lected 
  in 
  a 
  little 
  heap 
  ; 
  some 
  species 
  place 
  them 
  in 
  the 
  centre 
  of 
  

   the 
  mined 
  place, 
  and 
  others 
  in 
  a 
  corner. 
  

  

  " 
  If, 
  when 
  we 
  examine 
  the 
  mining 
  larva, 
  it 
  happens 
  to 
  be 
  

   at 
  work, 
  we 
  shall 
  see 
  it 
  seize 
  between 
  its 
  teeth, 
  as 
  between 
  

   pincers, 
  and 
  detach 
  the 
  parenchyma 
  of 
  the 
  leaf; 
  or 
  at 
  least 
  we 
  

   shall 
  perceive 
  that 
  a 
  part 
  of 
  the 
  leaf 
  previously 
  opaque 
  has 
  be- 
  

   come 
  transparent, 
  because 
  the 
  fleshy 
  portion 
  has 
  passed 
  into 
  the 
  

   body 
  of 
  the 
  insect. 
  The 
  two 
  jaws, 
  which 
  form 
  a 
  point 
  in 
  front 
  of 
  

   the 
  head, 
  are 
  well 
  fitted 
  to 
  open 
  a 
  road 
  in 
  the 
  substance 
  of 
  the 
  

   leaf 
  and 
  to 
  seize 
  minute 
  portions. 
  One 
  can 
  very 
  easily 
  observe 
  

   the 
  blotch 
  miner 
  of 
  the 
  rose, 
  while 
  excavating 
  in 
  the 
  thickness 
  of 
  

   the 
  leaf(?) 
  We 
  observe 
  still 
  more 
  easily 
  that 
  of 
  the 
  goosefoot, 
  

   or 
  orach, 
  because 
  in 
  the 
  places 
  which 
  it 
  mines 
  it 
  only 
  leaves 
  a 
  

   white 
  and 
  very 
  fine 
  skin 
  (G. 
  ncevferella). 
  

  

  " 
  The 
  labours 
  of 
  the 
  blotch 
  miners, 
  roughly 
  considered, 
  seem 
  

   to 
  have 
  in 
  them 
  nothing 
  more 
  singular 
  than 
  those 
  of 
  the 
  gallery 
  

   miners, 
  except 
  that 
  whereas 
  the 
  latter 
  always 
  mine 
  before 
  them,
