  latter 
  are 
  rather 
  short, 
  and 
  the 
  hnid 
  tibiae 
  either 
  red 
  or 
  glaucous, 
  vritli 
  

   niue 
  to 
  eleven 
  spines 
  in 
  tlie 
  outer

  The 
  supraanal 
  plate 
  is 
  triangular, 
  with 
  raised 
  margins; 
  the 
  furcula 
  

   consists 
  of 
  a 
  pair 
  of 
  slight 
  and 
  distant 
  or 
  very 
  distant 
  projections; 
  the 
  

   cerci 
  are 
  stout 
  and 
  heavy, 
  two 
  or 
  three 
  times 
  as 
  long- 
  as 
  broad, 
  mesially 
  

   contracted 
  and 
  apically 
  angulate; 
  the 
  subgenital 
  plate 
  is 
  broad, 
  

   broader 
  than 
  long 
  by 
  the 
  greater 
  or 
  less 
  elevation 
  of 
  the 
  entire 
  and 
  

   well-rounded 
  apical 
  margin. 
  

  

  There 
  are 
  but 
  two 
  species 
  known, 
  of 
  medium 
  size, 
  one 
  from 
  'New 
  

   Mexico 
  and 
  the 
  other 
  from 
  Iowa 
  and 
  Dakota.
