  Segment 
  VI. 
  

  

  E 
  — 
  a 
  small 
  delicate 
  seta 
  ; 
  single, 
  double, 
  or 
  triple. 
  D 
  — 
  a 
  delicate 
  seta 
  ; 
  usually 
  

   single, 
  sometimes 
  double. 
  C 
  — 
  not 
  represented. 
  B 
  — 
  a 
  small 
  stoutish 
  seta 
  ; 
  single. 
  

   A 
  — 
  a 
  minute 
  seta. 
  A 
  little 
  internal 
  to 
  B 
  there 
  is 
  a 
  delicate 
  single 
  seta 
  of 
  moderate 
  

   length 
  (B'). 
  

  

  Segment 
  VII. 
  

  

  E 
  — 
  a 
  small 
  delicate 
  seta 
  ; 
  single, 
  or 
  more 
  frequently 
  double 
  or 
  triple. 
  D 
  — 
  a 
  

   delicate 
  seta 
  ; 
  single. 
  C 
  — 
  not 
  represented. 
  B 
  — 
  a 
  small 
  stoutish. 
  seta 
  ; 
  single. 
  B' 
  — 
  

   a 
  delicate 
  single 
  seta, 
  similar 
  to 
  that 
  on 
  the 
  sixth 
  segment, 
  a 
  little 
  internal 
  to 
  B. 
  

   A 
  — 
  a 
  minute 
  seta. 
  The 
  correlation 
  of 
  the 
  setae 
  near 
  the 
  posterior 
  margin 
  of 
  this 
  

   segment 
  and 
  the 
  sixth 
  is 
  not 
  quite 
  clear, 
  and 
  the 
  difficulty 
  is 
  increased 
  on 
  this 
  

   segment 
  because, 
  owing 
  to 
  the 
  reduced 
  width, 
  the 
  relative 
  positions 
  are 
  misleading. 
  

   The 
  interpretation 
  suggested 
  is 
  based 
  on 
  the 
  facts 
  that 
  the 
  seta 
  D 
  is 
  in 
  line 
  with 
  the 
  

   corresponding 
  setae 
  on 
  the 
  more 
  anterior 
  segments, 
  and 
  the 
  seta 
  B 
  is 
  in 
  line 
  with, 
  

   and 
  similar 
  in 
  appearance 
  to 
  the 
  seta 
  B 
  on 
  the 
  other 
  segments. 
  

  

  Segment 
  VIII. 
  

  

  The 
  only 
  seta 
  found 
  on 
  this 
  segment 
  is 
  a 
  very 
  small 
  single 
  seta 
  situated 
  close 
  to 
  

   the 
  anterior 
  margin 
  of 
  the 
  segment 
  at 
  a 
  point 
  nearly 
  two-thirds 
  of 
  the 
  distance 
  

   from 
  the 
  lateral 
  border 
  to 
  the 
  middle 
  line. 
  This 
  seta 
  may 
  represent 
  A, 
  which 
  

   appears 
  to 
  be 
  absent, 
  but 
  if 
  so 
  it 
  is 
  displaced 
  outwards 
  and 
  a 
  little 
  backwards. 
  

  

  Segment 
  IX. 
  

  

  No 
  setae. 
  

  

  A 
  typical 
  segment 
  may 
  be 
  regarded 
  as 
  having 
  the 
  following 
  setae 
  : 
  a 
  medio-lateral 
  

   seta, 
  a 
  postero-lateral 
  seta, 
  an 
  outer 
  ventral 
  seta, 
  an 
  inner 
  ventral 
  seta, 
  and 
  a 
  minute 
  

   anterior 
  ventro-central 
  seta.
