  two, 
  and 
  we 
  have 
  them 
  6-jointed. 
  There 
  is, 
  however, 
  no 
  

   true 
  articuhition 
  between 
  the 
  subdivisions, 
  and 
  the 
  antenna? 
  

   are 
  little, 
  if 
  at 
  all, 
  bent 
  at 
  these 
  points. 
  A 
  similar 
  process 
  

   of 
  subdivision 
  takes 
  place 
  in 
  the 
  genus 
  Heteromurus, 
  Wankel 
  

   r=TempIetonia, 
  Lubbock), 
  except 
  that 
  only 
  the 
  first 
  segment 
  

   is 
  divided, 
  resulting 
  in 
  5-jointed 
  antenna?. 
  This 
  has 
  been 
  

   ilhistiated 
  in 
  the 
  case 
  of 
  11. 
  nitidus 
  (Tempi.) 
  by 
  Bonier 
  

   (1901),

  I 
  regard 
  all 
  species 
  of 
  Collembola 
  as 
  having 
  primarily 
  

   •4-jointed 
  antenna^, 
  and 
  these 
  may 
  be 
  secondarily 
  divided 
  as 
  

   above, 
  or 
  ant. 
  iii. 
  and 
  iv. 
  may 
  be 
  divided 
  as 
  in 
  the 
  genus 
  

   Pttnothrix, 
  or 
  only 
  ant. 
  iv. 
  as 
  in 
  Arrhopalites 
  and 
  some 
  other 
  

   genera 
  of 
  the 
  Sminthuridse. 
  

  

  Orchesella 
  flavescens 
  (Bourl.), 
  Agr.^ 
  in 
  England. 
  

  

  = 
  Heterotoma 
  flavescens, 
  Bourlet 
  (1839). 
  

   Orchesella 
  rufescens, 
  Lubbock, 
  (1862) 
  p. 
  592. 
  

   Orchesella 
  Jlavescens, 
  Agren, 
  (1903) 
  pp. 
  149-1.51. 
  

  

  This 
  species 
  has 
  been 
  recorded 
  from 
  England 
  under 
  the 
  

   n&.vnQo{ 
  0. 
  rufescens; 
  but 
  Agren, 
  in 
  his 
  paper 
  on 
  the 
  Aptery- 
  

   gotal 
  Fauna 
  of 
  ISouth 
  Sweden 
  (1903) 
  has 
  shown 
  that 
  it 
  should 
  

   be 
  known 
  as 
  . 
  jlavescens 
  of 
  Bourlet, 
  the 
  earlier 
  references 
  to 
  

   Podura 
  rnfeseens 
  being 
  insufficient 
  for 
  identification. 
  It 
  is 
  

   apparently 
  not 
  very 
  common 
  in 
  Enghind, 
  for 
  it 
  has 
  only 
  

   been 
  found 
  and 
  recorded 
  on 
  iQ.w 
  occasions. 
  The 
  early 
  

   records, 
  however, 
  for 
  Illngland 
  seem 
  to 
  have 
  been 
  overlooked, 
  

   for 
  Bagnall 
  (1908), 
  p. 
  82, 
  includes 
  Orchesella 
  rufescens 
  from 
  

   Delamere 
  Forest, 
  Clieshire, 
  in 
  a 
  list 
  of 
  *■' 
  Additions 
  to 
  the 
  

   Fauna 
  of 
  Great 
  Britain," 
  and 
  (1909), 
  p. 
  504, 
  writes 
  of 
  it 
  

   being 
  '' 
  found 
  nut 
  uncommonly 
  in 
  Delamere 
  Forest," 
  and 
  

   " 
  though 
  this 
  is 
  a 
  widely 
  distributed 
  European 
  species, 
  and 
  is 
  a 
  

   common 
  one 
  in 
  many 
  countries, 
  it 
  is 
  only 
  now 
  that 
  we 
  are 
  

   able 
  to 
  record 
  it 
  as 
  a 
  British 
  Insect." 
  

  

  The 
  previous 
  references 
  to 
  this 
  insect 
  in 
  England 
  are 
  a3 
  

   follows 
  :

  Lubbock 
  (1862), 
  p. 
  592, 
  says 
  of 
  0. 
  rufescens: 
  — 
  "The 
  

   body 
  is 
  rather 
  narrow, 
  and 
  much 
  less 
  heavy 
  than 
  iu 
  i\\& 
  other 
  

   English 
  species." 
  The 
  paper 
  is 
  written 
  of 
  Collembola 
  found 
  

   by 
  Lubbock 
  since 
  writing 
  Part 
  I. 
  of 
  his 
  " 
  Notes 
  on 
  the 
  Thysa- 
  

   nura," 
  and 
  for 
  some 
  of 
  the 
  species 
  he 
  mentions 
  Kent 
  as 
  a 
  

   locality 
  ; 
  so 
  that 
  I 
  regard 
  the 
  above 
  as 
  a 
  distinct 
  record 
  of 
  the 
  

   species 
  from 
  England. 
  

  

  (Sir 
  John 
  Lubbock, 
  in 
  his 
  Monograph 
  (1873), 
  himself 
  seems 
  

   to 
  have 
  overlooked 
  the 
  fact 
  that 
  he 
  had 
  previously 
  found 
  and 
  

   recorded 
  this 
  species, 
  for
