  * 
  The 
  author 
  has 
  sometimes 
  inadvertently 
  used 
  tbe 
  term 
  urite 
  instead 
  of 
  urostemite 
  ; 
  Lacaze-Duthier's 
  

   term 
  urito 
  is 
  equivalent 
  to 
  our 
  uromere. 
  

  

  Tbe 
  engraver 
  has 
  in 
  some 
  cases 
  omittedl 
  tbe 
  accents 
  distinguishing 
  the 
  parts 
  similarly 
  lettered 
  on 
  tbe 
  

   plates, 
  but 
  no 
  confusion 
  is 
  likely 
  to 
  arise, 
  upon 
  careful 
  examination 
  of 
  tbe 
  figures 
  and 
  comparison 
  with 
  

   the
