  The 
  President 
  informed 
  the 
  meeting 
  that 
  among 
  the 
  insects 
  received 
  from 
  Mr. 
  

   Thvvaites, 
  were 
  many 
  rare 
  species, 
  and 
  nearly 
  half 
  the 
  number 
  were 
  unique 
  specimens. 
  

  

  Mr. 
  Adam 
  White 
  exhibited 
  drawings 
  of 
  the 
  nests 
  of 
  two 
  species 
  of 
  spiders 
  ; 
  the 
  

   one, 
  found 
  by 
  S. 
  S. 
  Saunders, 
  Esq., 
  in 
  Albania, 
  was 
  formed 
  of 
  the 
  seed-vessels 
  of 
  Pa- 
  

   liurus 
  aculeatus, 
  four 
  of 
  wLich 
  were 
  arranged 
  symmetrically, 
  and 
  connected 
  by 
  a 
  web: 
  

   the 
  other 
  was 
  found 
  by 
  M. 
  Weilenmann, 
  of 
  St. 
  Gall, 
  Switzerland, 
  in 
  a 
  wood 
  near 
  Per- 
  

   nambuco 
  ; 
  it 
  was 
  of 
  a 
  grayish 
  white 
  colour, 
  with 
  a 
  penthouse-like 
  roof, 
  on 
  which 
  were 
  

   seven 
  rows 
  of 
  scale-like 
  appendages, 
  and 
  a 
  row 
  round 
  the 
  margin 
  : 
  it 
  was 
  attached 
  by 
  

   a 
  pedicel, 
  three 
  inches 
  long, 
  to 
  a 
  leaf. 
  M. 
  Weilenmann 
  informed 
  Mr. 
  White 
  that 
  the 
  

   spider 
  was 
  small, 
  but 
  Mr. 
  White 
  believed 
  he 
  had 
  seen 
  only 
  the 
  young 
  ones. 
  

  

  Mr. 
  White 
  exhibited 
  specimens 
  of 
  a 
  minute 
  Podura, 
  found 
  by 
  Dr. 
  Sutherland 
  on 
  

   the 
  ice, 
  some 
  miles 
  from 
  the 
  shore 
  of 
  Wellington 
  Channel, 
  under 
  a 
  species 
  of 
  Nostoc 
  

   growing 
  there. 
  It 
  was 
  closely 
  related 
  to 
  the 
  Desoria 
  glacialis, 
  Nicolet, 
  which 
  M. 
  De- 
  

   sor 
  found 
  among 
  tbe 
  glaciers 
  of 
  the 
  Swiss 
  Alps, 
  in 
  countless 
  numbers, 
  under 
  stones 
  or 
  

   on 
  the 
  margins 
  of" 
  crevasses 
  et 
  des 
  baignoires." 
  MM. 
  Desor, 
  Pourtales, 
  and 
  Agassiz 
  

   also 
  saw 
  them 
  running 
  into 
  ice, 
  apparently 
  very 
  compact, 
  but 
  on 
  breaking 
  off 
  a 
  piece 
  

   it 
  was 
  found 
  to 
  be 
  pierced 
  with 
  numerous 
  canals, 
  into 
  which 
  the 
  Desoriae 
  leaped 
  and 
  

   ran, 
  looking 
  like 
  drops 
  of 
  blood.

  Dr. 
  Sutherland 
  added, 
  in 
  answer 
  to 
  a 
  question 
  from 
  the 
  President, 
  that 
  he 
  only 
  

   found 
  this 
  Podura 
  under 
  the 
  Nostoc 
  ; 
  and 
  that 
  although 
  it 
  was 
  in 
  plenty, 
  the 
  indivi- 
  

   duals 
  remained 
  free, 
  and 
  did 
  not 
  assemble 
  in 
  masses 
  after 
  the 
  manner 
  of 
  the 
  common 
  

   English 
  Podura. 
  But 
  he 
  had 
  also 
  found 
  what 
  he 
  thought 
  were 
  two 
  other 
  distinct 
  

   species, 
  under 
  stones 
  where 
  no 
  Nostoc 
  grew. 
  

  

  Mr. 
  White 
  also 
  exhibited 
  some 
  more 
  of 
  the 
  insects 
  collected 
  in 
  the 
  Himalayas 
  by 
  

   Dr. 
  J. 
  D. 
  Hooker, 
  pointing 
  out 
  especially 
  a 
  beautiful 
  minute 
  Cicindela, 
  a 
  Cercidocerus 
  

   with 
  two 
  white 
  lines 
  on 
  the 
  thorax, 
  a 
  Distenia, 
  several 
  pretty 
  Phytophaga, 
  including 
  

   Adimonia 
  variolaris, 
  Aplosonyx 
  fasciatus, 
  &c., 
  the 
  Hemipterous 
  Poecilocoris 
  Chil- 
  

   dreni, 
  a 
  new 
  spider 
  of 
  the 
  genus 
  Gastrocantha, 
  and 
  one 
  of 
  the 
  Myriapodous 
  genus 
  

   Zephronia. 
  

  

  Mr. 
  A. 
  F. 
  Sheppard 
  exhibited 
  specimens 
  of 
  Halias 
  clorana, 
  bred 
  from 
  osiers 
  at 
  

   Fulham, 
  and 
  a 
  Cerura 
  vinula, 
  var. 
  minax, 
  Hiib. 
  

  

  Mr. 
  Grant 
  exhibited 
  twelve 
  specimens 
  of 
  the 
  rare 
  Adela 
  cuprella, 
  obtained 
  by 
  re- 
  

   peated 
  visits 
  to 
  the 
  dwarf 
  sallows 
  on 
  Wimbledon 
  Common 
  during 
  the 
  late 
  cold 
  month 
  

   of 
  April. 
  

  

  Mr. 
  S. 
  Stevens 
  exhibited 
  a 
  fine 
  series 
  of 
  Goliathus 
  Polyphemus 
  from 
  Cape 
  Palmas, 
  

   and 
  of 
  Callithea 
  Sapphira, 
  male 
  and 
  female, 
  collected 
  by 
  Mr. 
  Bates 
  at 
  Santarem, 
  on 
  

   the 
  Amazon 
  river. 
  

  

  The 
  President 
  read 
  the 
  following 
  letter, 
  addressed 
  to 
  him 
  by 
  Mr. 
  Ainger 
  : 
  — 
  

  

  " 
  2, 
  Carlton 
  Hill, 
  Edgware 
  Road, 
  

  

  " 
  April 
  17, 
  1852. 
  

   " 
  Sir, 
  

  

  " 
  I 
  observe 
  that 
  at 
  a 
  recent 
  meeting 
  of 
  the 
  Entomological 
  Society, 
  you 
  

   read 
  a 
  paper 
  of 
  inquiry 
  as 
  to 
  the 
  best 
  method 
  of 
  extirpating 
  cock-roaches. 
  

  

  " 
  I 
  have 
  for 
  many 
  years, 
  and 
  in 
  three 
  different 
  houses, 
  used 
  a 
  plan 
  which 
  gets 
  rid 
  

   of 
  ihcin 
  more 
  rapidly 
  and 
  more 
  completely 
  than 
  any 
  I 
  have 
  heard 
  of. 
  

  

  " 
  In 
  the 
  kitchen 
  hearth, 
  within 
  the 
  fender, 
  but 
  at 
  one 
  side 
  of 
  the 
  fire, 
  I 
  cut 
  a 
  hole
