  Immediately 
  above 
  the 
  anal 
  orifice, 
  at 
  the 
  junction 
  of 
  the 
  pygidium 
  with 
  the 
  free 
  

   abdominal 
  segment, 
  is 
  a 
  transverse 
  linear 
  group 
  of 
  14-15 
  circular 
  gland-pores 
  of 
  

   a 
  similar 
  form 
  to 
  those 
  surrounding 
  the 
  genital 
  orifice. 
  The 
  large 
  glandular 
  pores 
  

   of 
  the 
  dorsum 
  extending 
  as 
  far 
  as 
  the 
  region 
  of 
  the 
  mesothoracic 
  stigmata. 
  

  

  Female, 
  second 
  stage. 
  A 
  little 
  more 
  than 
  one- 
  third 
  the 
  length 
  of 
  the 
  adult 
  female 
  ; 
  

   narrowly 
  elongate, 
  sides 
  parallel 
  ; 
  cephalic 
  margin 
  slightly 
  narrower 
  than 
  the 
  

   pygidium. 
  The 
  last-named 
  (fig. 
  24, 
  e, 
  j) 
  with 
  the 
  marginal 
  appendages 
  similar 
  

   to 
  those 
  in 
  the 
  adult 
  ; 
  but 
  the 
  serrations 
  of 
  the 
  median 
  lobes 
  more 
  strongly 
  defined, 
  

   and 
  the 
  second 
  lobe 
  relatively 
  narrower 
  and 
  longer.
