  Testes 
  and 
  sperm-duct-funnels 
  free 
  in 
  the 
  x. 
  and 
  xi. 
  seg- 
  

   ments. 
  A 
  pair 
  of 
  little 
  grape-like 
  sperm-sacs 
  depends 
  from 
  

   septum 
  xi.-xii. 
  into 
  the 
  xii. 
  segment. 
  

  

  A 
  pair 
  of 
  tubular 
  prostates 
  lies 
  in 
  the 
  xviii. 
  segment, 
  but 
  

   a 
  short 
  proximal 
  part 
  of 
  these 
  organs 
  stretches 
  out 
  into 
  

   the 
  xix. 
  segment 
  through 
  septum 
  xviii.-xix. 
  The 
  delicate 
  

   axial 
  tube 
  of 
  each 
  prostate 
  is 
  not 
  ramified. 
  The 
  sperm-ducts 
  

   enter 
  the 
  proximal 
  part 
  of 
  the 
  muscular 
  ducts 
  of 
  the 
  prostates, 
  

   which 
  is 
  a 
  little 
  coiled. 
  There 
  are 
  no 
  penial 
  setae. 
  

  

  A

  of 
  ovaries

  oviduct-funnels

  A 
  pair 
  of 
  spermathecse 
  in 
  the 
  viii. 
  segment. 
  These 
  organs 
  

   consist 
  only 
  of 
  a 
  long 
  pear-shaped 
  ampulla. 
  There 
  are 
  no 
  

   diverticula.

  This 
  interesting 
  new 
  species 
  is 
  distinguished 
  from 
  others 
  

   of 
  the 
  same 
  genus 
  by 
  the 
  possession 
  of 
  a 
  single 
  pair 
  of 
  

   spermathecse. 
  This 
  character 
  requires 
  some 
  slight 
  modifi- 
  

   cation 
  of 
  the 
  definition 
  of 
  the 
  genus 
  Plutellus 
  as 
  given 
  by 
  

   Michaelsen 
  *. 
  Sperraathecal 
  pores 
  on 
  the 
  viii. 
  segment, 
  in 
  

   the 
  zone 
  of 
  setse, 
  were 
  already 
  found 
  by 
  Michaelsen 
  in 
  

   his 
  Plutellus 
  indicus 
  f. 
  typica 
  f, 
  but 
  that 
  species 
  possesses 
  

   a 
  second 
  pair 
  of 
  spermathecal 
  pores 
  in 
  intersegmental 
  

   furrow 
  viii.-ix.
