  Female. 
  — 
  Color 
  as 
  in 
  male; 
  form 
  of 
  abdomen 
  much 
  the 
  same, 
  

   seventh 
  tergite 
  about 
  one-third 
  shorter 
  than 
  sixth, 
  the 
  lateral 
  angles 
  

   produced 
  distinctly 
  beyond 
  the 
  keeled 
  and 
  slightly 
  tuberculate 
  mid- 
  

   dle 
  of 
  hind 
  margin; 
  eighth 
  tergite 
  about 
  semicircular,

   tudinally 
  and 
  corrugated

  ninth 
  somewhat 
  longer

  herringbone 
  fashion, 
  narrowed, 
  rounded,

  less 
  sinuate

  seventh 
  sternite 
  somewhat 
  shorter 
  than 
  sixth, 
  its 
  hind 
  

   margin 
  concave 
  laterally 
  and 
  forming 
  a 
  distinct 
  rounded 
  process 
  

   medianly; 
  eighth 
  sternite 
  appearing 
  as 
  an 
  elliptical 
  plate 
  on

  In 
  the 
  male 
  nymph 
  the 
  eighth 
  tergite 
  is 
  broadly 
  visible 
  across 
  

   base 
  of 
  anal 
  tube, 
  the 
  ninth 
  apparently 
  is 
  membraneous, 
  the 
  seventh 
  

   has 
  a 
  large 
  upwardly 
  and 
  backwardly 
  projecting 
  pointed 
  process, 
  

   and 
  the 
  lateral 
  angles 
  slightly 
  pointed 
  tuberculate; 
  in 
  the 
  female 
  

   nymph 
  the 
  seventh 
  tergite 
  has 
  a 
  rather 
  prominent 
  erect 
  tubercle, 
  the 
  

   eighth 
  and 
  ninth 
  are 
  keeled 
  and 
  less 
  rounded 
  apically 
  than 
  in 
  adult 
  

   since 
  they 
  form 
  the 
  roof 
  of 
  complete 
  segments 
  inclosing 
  the 
  anal 
  tube. 
  

  

  GHILIANELLA 
  PERSIMILIS. 
  new 
  species. 
  

  

  Male. 
  — 
  Very 
  similar 
  to 
  male 
  of 
  prdductilis; 
  the 
  only 
  tangible 
  

   difference 
  seems 
  to 
  be 
  that 
  in 
  this 
  species 
  the 
  narrowed 
  portion 
  of 
  the 
  

   seventh 
  tergite 
  is 
  distinctly 
  longer 
  than 
  the 
  terminal 
  expanded, 
  then 
  

   apiculate 
  part 
  (fig. 
  170), 
  while 
  in 
  productilis 
  it 
  is 
  distinctly 
  shorter.

  Female. 
  — 
  Color 
  much 
  as 
  in 
  male 
  ; 
  very 
  similar 
  to 
  female 
  of 
  produc- 
  

   tilis, 
  the 
  chief 
  distinction, 
  being 
  in 
  the 
  form 
  of 
  tergites 
  7-9 
  and 
  

   sternite 
  7 
  ; 
  these 
  have 
  been 
  mentioned 
  in 
  the 
  key, 
  to 
  the 
  descriptions 
  

   in 
  which 
  may 
  be 
  added 
  that 
  the 
  eighth 
  tergite 
  is 
  much 
  broader 
  than 
  

   long, 
  transversely 
  wrinkled, 
  and 
  very 
  obtusely 
  angulate 
  at 
  apex; 
  

   tergite 
  9 
  is 
  somewhat 
  wrinkled 
  above 
  and 
  much 
  narrowed 
  apically 
  ; 
  

   hind 
  margin 
  of 
  sternite 
  7 
  is 
  only 
  slightly 
  convex 
  medianly 
  and 
  con- 
  

   cave 
  laterally 
  (fig. 
  172).
