  8. 
  LASIOPODES. 
  

  

  In 
  this 
  group 
  I 
  have 
  comprised 
  two 
  genera, 
  containing 
  species 
  of 
  small 
  size, 
  living 
  

   upon 
  flowers. 
  Although 
  differing 
  remarkably 
  in 
  appearance 
  and 
  characters, 
  not 
  less 
  

   from 
  each 
  other 
  than 
  from 
  all 
  other 
  genera 
  of 
  the 
  tribe 
  known 
  to 
  me, 
  I 
  have 
  been 
  

   induced 
  to 
  associate 
  them 
  together 
  on 
  account 
  of 
  the 
  following 
  characters, 
  which 
  they 
  

   have 
  in 
  common. 
  

  

  The 
  anterior 
  coxae 
  are 
  large, 
  conical 
  and 
  protuberant 
  ; 
  the 
  abdomen 
  is 
  very 
  small, 
  

   and 
  the 
  sutures 
  between 
  the 
  anterior 
  segments 
  are 
  nearly 
  effaced 
  ; 
  the 
  last 
  segment 
  

   is 
  conical, 
  free, 
  and 
  larger 
  than 
  usual. 
  The 
  parapleurae 
  are 
  narrow. 
  The 
  claws 
  are 
  

   diverging, 
  with 
  a 
  very 
  short 
  bisetose 
  onychium 
  ; 
  the 
  posterior 
  tibiae 
  are 
  armed 
  with 
  

   two 
  spurs, 
  but 
  the 
  anterior 
  tibiae 
  have 
  no 
  spur.
