  observation, 
  whicli 
  was, 
  in 
  fact, 
  made 
  a 
  little 
  earlier.

  W.

  Lamborn

  :— 
  

  

  "' 
  I 
  saw 
  a 
  most 
  interesting 
  incident 
  only 
  this 
  evening. 
  Two 
  

   tiny 
  birds, 
  no 
  larger 
  than 
  the 
  little 
  Cordon 
  Bleu 
  [Esfrilda 
  

   flioenicotis 
  , 
  Swains.] 
  or 
  Rouge, 
  were 
  vieing 
  with 
  each 
  other 
  in 
  

   pursuit 
  of 
  what 
  at 
  a 
  distance 
  I 
  took 
  to 
  be 
  a 
  large 
  black 
  Noctuid 
  

   now 
  common 
  in 
  the 
  house. 
  The 
  two 
  birds 
  got 
  it 
  down 
  and 
  

   pecked 
  it 
  vigorously, 
  but 
  it 
  escaped, 
  only 
  to 
  be 
  attacked 
  by 
  

   another 
  similar 
  little 
  bird 
  near 
  by. 
  Then 
  all 
  three 
  attacked 
  

   it, 
  and 
  so 
  I 
  flung 
  a 
  stick 
  at 
  them, 
  and 
  they 
  flew 
  off. 
  To 
  my 
  

   astonishment 
  the 
  insect 
  turned 
  out 
  to 
  be 
  a 
  Pap. 
  nireus, 
  Cram., 
  

   or 
  one 
  of 
  the 
  closely 
  allied 
  species, 
  with 
  both 
  fore-wings, 
  the 
  

   right 
  especially, 
  badly 
  torn 
  behind, 
  but 
  its 
  energies 
  were 
  

   little 
  impaired. 
  I 
  could 
  not 
  catch 
  it, 
  and 
  by 
  and 
  by 
  it 
  

   flew 
  into 
  a 
  lime 
  tree 
  and 
  finally 
  escaped." 
  

  

  Observations 
  on 
  the 
  larva 
  and 
  pupa 
  of 
  Uropteryx 
  

   SAMBUCARiA, 
  L.' 
  — 
  Prof. 
  PoULTON 
  exhibited 
  a 
  pale 
  yellowish- 
  

   grey 
  pupa 
  of 
  sambucaria 
  in 
  its 
  open 
  network 
  cocoon 
  spun 
  

   among 
  strips 
  and 
  small 
  pieces 
  of 
  white 
  paper. 
  It 
  had 
  been 
  

   already 
  shown 
  that 
  the 
  colours 
  were 
  adjusted 
  so 
  as 
  to 
  har- 
  

   monise 
  with 
  those 
  of 
  the 
  normal 
  surroundings 
  — 
  dark 
  or 
  pale

  of 
  Animals,"

  Trans. 
  

   Ent. 
  Soc, 
  1910, 
  pp. 
  143, 
  144). 
  Although 
  this 
  power 
  was 
  

   present 
  in 
  many 
  butterflies, 
  sambucaria 
  was 
  the 
  only 
  moth 
  

   pupa 
  in 
  which 
  it 
  had 
  been 
  observed. 
  The 
  chrysalis 
  also 
  

   resembled 
  that 
  of 
  certain 
  butterflies, 
  e. 
  g. 
  Pyrameis 
  atalanta, 
  

   L., 
  in 
  the 
  rapid 
  lashing 
  movements 
  of 
  the 
  abdominal 
  segments 
  

   which 
  took 
  place 
  on 
  disturbance 
  and 
  were 
  probably 
  a 
  defence 
  

   against 
  enemies. 
  

  

  The 
  larva, 
  found 
  upon 
  pear 
  in 
  the 
  summer 
  of 
  1918, 
  was 
  

   over 
  2f 
  in. 
  long 
  when 
  mature. 
  Living 
  by 
  itself 
  in 
  a 
  large 
  

   sleeve 
  out 
  of 
  doors 
  in 
  almost 
  normal 
  conditions, 
  this 
  single 
  

   larva 
  offered 
  the 
  opportunity 
  of 
  studying 
  certain 
  instincts 
  

   with 
  a 
  precision 
  unattainable 
  when 
  many 
  caterpillars 
  are 
  

   kept 
  together 
  and 
  disturb 
  one 
  another. 
  I 
  especially 
  wished 
  to 
  

   determine 
  the 
  time 
  at 
  which 
  the 
  rigid, 
  wonderfully 
  twig-like, 
  

   diurnal 
  attitude 
  was 
  abandoned 
  and 
  feeding 
  begun. 
  The 
  

   hours 
  are 
  summer 
  time.
