  The 
  eggs 
  are 
  long 
  and 
  of 
  a 
  bright 
  yellow 
  colour, 
  and 
  are 
  laid 
  in 
  

   rows 
  like 
  a 
  lot 
  of 
  little 
  barrels 
  placed 
  close 
  together. 
  When 
  

   the 
  young 
  larvae 
  hatch 
  in 
  about 
  five 
  days 
  they 
  feed 
  on 
  the 
  

   Aphidae 
  on 
  the 
  trees. 
  Judging 
  from 
  my 
  experience 
  last 
  year 
  

   they 
  become 
  full 
  fed 
  by 
  the 
  beginning 
  of 
  July, 
  pupate 
  on 
  the 
  

   trees 
  and 
  remain 
  in 
  the 
  pupal 
  state 
  for 
  eight 
  and 
  nine 
  days. 
  

   The 
  perfect 
  insect 
  then 
  remains 
  on 
  the 
  trees 
  and 
  near 
  the 
  rufa 
  

   nests 
  for 
  the 
  rest 
  of 
  the 
  year, 
  hibernating 
  on 
  the 
  trees 
  and 
  

   sparingly 
  in 
  the 
  nests.

  and 
  

   Messrs. 
  Champion, 
  Cokbett,

  discussed 
  Mr.

  observations. 
  

  

  PuPARiA 
  UNIDENTIFIED.^ 
  — 
  Mr. 
  E. 
  E. 
  Green 
  exhibited 
  some 
  

   puparia 
  found 
  on 
  decayed 
  wood, 
  at 
  the 
  margin 
  of 
  a 
  lake 
  near 
  

   Shrewsbury, 
  in 
  the 
  month 
  of 
  September. 
  The 
  puparia 
  are 
  of 
  

   the 
  shape 
  of 
  a 
  limpet-shell, 
  open 
  below, 
  with 
  a 
  sub-acute 
  apex 
  ; 
  

   of 
  a 
  dense 
  structure 
  and 
  pitchy 
  black 
  colour 
  ; 
  the 
  outer 
  surface 
  

   rugose. 
  The 
  material 
  of 
  which 
  they 
  are 
  composed 
  is 
  probably 
  

   excrementitious. 
  The 
  pupa 
  of 
  the 
  insect 
  occupies 
  the 
  con- 
  

   cavity 
  of 
  this 
  cover 
  and 
  is 
  exposed 
  below. 
  

  

  Mr. 
  Green 
  asked 
  whether 
  any 
  Fellows 
  present 
  were 
  ac- 
  

   quainted 
  with 
  these 
  puparia, 
  which 
  he 
  thought 
  might 
  be 
  those 
  

   of 
  a 
  Coleopteron. 
  Mr. 
  Collin 
  suggested 
  that 
  they 
  might 
  be 
  

   those 
  of 
  a 
  mycetophilous 
  Dipteron, 
  Mr. 
  Green 
  then 
  remarking 
  

   that 
  he 
  had 
  seen 
  somewhat 
  similar 
  Mycetophiled 
  cases 
  in 
  

   Ceylon.

  — 
  Prof. 
  Poulton 
  said 
  that 
  he 
  had 
  received, 
  on 
  May 
  

   27, 
  a 
  letter 
  from 
  Mr. 
  C. 
  F. 
  M. 
  Swynnerton, 
  giving 
  an 
  account 
  

   of 
  some 
  interesting 
  breeding 
  experiments 
  on

  I 
  have 
  a 
  little 
  news 
  for 
  you 
  at 
  last, 
  not 
  about 
  ethalion 
  

  

  this 
  time 
  but 
  about 
  dardanus. 
  Mr. 
  E. 
  E. 
  Piatt 
  sent 
  me 
  last 
  

  

  year 
  2 
  families 
  of 
  cenea 
  pupae. 
  The 
  first 
  got 
  here 
  just 
  in 
  time, 
  

  

  the 
  second 
  just 
  too 
  late 
  (emerged 
  and 
  dead). 
  Each 
  had 
  a 
  

  

  slight 
  lii2')2')ocoon 
  taint, 
  shown 
  by 
  2 
  or 
  3 
  of 
  the 
  ?? 
  in 
  each 
  being 
  

  

  Jdppocoon. 
  There 
  were 
  no 
  dardanus 
  obtainable 
  here 
  then, 
  

  

  though 
  I 
  searched 
  myself 
  and 
  put 
  on 
  my 
  good 
  native 
  collector
