  Contributions 
  towards 
  the 
  

  

  the 
  third, 
  fourth 
  and 
  last 
  disposed 
  more 
  in 
  a 
  transverse 
  line 
  ; 
  on 
  

   the 
  side 
  is 
  a 
  row 
  of 
  black 
  dots, 
  one 
  on 
  each 
  segment, 
  and 
  another 
  

   similar 
  row 
  lower 
  down 
  above 
  the 
  legs. 
  Six 
  pectoral 
  legs 
  black, 
  

   eight 
  ventral 
  and 
  two 
  anal 
  legs 
  the 
  colour 
  of 
  the 
  body. 
  

  

  Found 
  from 
  the 
  beginning 
  of 
  April 
  to 
  the 
  middle 
  of 
  May 
  on 
  

   the 
  young 
  shoots 
  of 
  Stellaria 
  idiginosa 
  (fig. 
  3 
  a), 
  the 
  leaves 
  of 
  

   which 
  it 
  fastens 
  together, 
  making 
  a 
  habitation 
  in 
  which 
  it 
  lives 
  and 
  

   eats, 
  and 
  from 
  which 
  it 
  removes 
  and 
  forms 
  another 
  as 
  often 
  as 
  the 
  

   supply 
  of 
  food 
  becomes 
  exhausted. 
  Unlike 
  its 
  congeners, 
  it 
  is 
  

   very 
  dull 
  and 
  inactive 
  in 
  its 
  movements.

  Imago 
  (fig.

  — 
  Appears 
  in 
  July. 
  I 
  described 
  this 
  species 
  in 
  

   the 
  Transactions 
  of 
  this 
  Society 
  (Vol. 
  I. 
  (N.S.) 
  p. 
  101) 
  from 
  a 
  

   specimen 
  taken 
  in 
  Mr. 
  Stainton's 
  hedges, 
  but 
  now, 
  compared 
  with 
  

   a 
  bred 
  specimen, 
  the 
  colours 
  are 
  dull 
  and 
  faded. 
  

  

  First 
  the 
  perfect 
  insect 
  and 
  then 
  the 
  larva 
  were 
  discovered 
  by 
  

   Mr. 
  Stainton 
  at 
  Lewisham, 
  and 
  I 
  found 
  the 
  latter 
  at 
  Penge 
  and 
  

   West 
  Wickham. 
  

  

  Genus 
  Coleophora, 
  Zeller. 
  

   The 
  larvae 
  of 
  this 
  genus 
  are 
  singularly 
  interesting. 
  They 
  make 
  

   cases, 
  which 
  in 
  the 
  several 
  species 
  differ 
  greatly 
  in 
  form 
  and 
  colour; 
  

   in 
  these 
  they 
  live 
  and 
  literally 
  move, 
  for 
  they 
  carry 
  them 
  about 
  

   throughout 
  the 
  whole 
  period 
  of 
  their 
  existence. 
  They 
  feed 
  on 
  

   the 
  leaves 
  of 
  plants, 
  subsisting 
  on 
  the 
  parenchyma, 
  to 
  obtain 
  

   which 
  they 
  partially 
  emerge 
  from 
  their 
  cases, 
  and 
  thrust 
  their 
  

   bodies 
  into 
  leaves 
  between 
  the 
  cuticles, 
  often 
  so 
  far 
  that 
  but 
  a 
  

   small 
  portion 
  remains 
  in 
  the 
  case, 
  but 
  they 
  appear 
  to 
  have 
  no 
  dif- 
  

   ficulty 
  in 
  returning. 
  As 
  they 
  grow 
  they 
  enlarge 
  their 
  cases 
  by 
  

   adding 
  portions 
  of 
  the 
  leaves 
  of 
  the 
  plant 
  upon 
  which 
  they 
  feed, 
  

   the 
  sutures 
  of 
  the 
  pieces 
  joined 
  on 
  usually 
  remaining 
  visible 
  ; 
  

   they 
  also 
  have 
  the 
  power 
  of 
  forming 
  entirely 
  new 
  cases. 
  As 
  might 
  

   be 
  expected 
  from 
  these 
  larvae 
  having 
  to 
  carry 
  such 
  cumbersome 
  

   cases, 
  their 
  movements 
  are 
  not 
  very 
  active, 
  and 
  in 
  some 
  instances 
  

   are 
  very 
  grotesque. 
  When 
  full-fed 
  they 
  turn 
  round 
  in 
  their 
  cases, 
  

   after 
  having 
  made 
  the 
  mouth-end 
  fast, 
  and 
  then 
  become 
  pupae 
  ; 
  

   and 
  when 
  they 
  assume 
  the 
  perfect 
  state, 
  the 
  pupa 
  skin 
  does 
  not 
  

   project 
  from 
  the 
  case, 
  but 
  remains 
  within, 
  so 
  that 
  it 
  frequently 
  

   happens 
  to 
  the 
  collector 
  that 
  he 
  takes 
  cases 
  fastened 
  up, 
  but 
  from 
  

   which 
  the 
  tenant 
  has 
  escaped.
