  I 
  have 
  refrained 
  from 
  giving 
  a 
  key 
  to 
  the 
  included 
  forms 
  because 
  

   the 
  numerous 
  species 
  described 
  by 
  Blanchard 
  and 
  Philippi 
  are 
  almost 
  

   certainly 
  a 
  mixture 
  of 
  several 
  genera, 
  and 
  until 
  more 
  of 
  these 
  species 
  

   ,are 
  rediscovered 
  it 
  would 
  be 
  foolhardy 
  to 
  attempt 
  a 
  key 
  in 
  this 
  group. 
  

  

  I 
  am 
  including 
  in 
  Limnofhila 
  the 
  species 
  described 
  as 
  Polymoria 
  

   Philippi. 
  The 
  only 
  species 
  I 
  have 
  ever 
  seen, 
  P. 
  lutea, 
  is 
  represented 
  

   by 
  a 
  single 
  legless 
  specimen, 
  and 
  I 
  am 
  unable 
  to 
  decide 
  as 
  to 
  whether 
  

   or 
  not 
  this 
  insect 
  has 
  spurred 
  tibiae.
