  Extremity

  considerably 
  clavate, 
  somewhat 
  

   recurved,

  nearly 
  half 
  as 
  long

  the 
  sujiraanal 
  plate, 
  lying

  which 
  taper 
  rajiidly

  Dodge 
  originally 
  described 
  it 
  from 
  Glencoe, 
  Dodge 
  County, 
  Nebraska, 
  

   and 
  it 
  has 
  since 
  been 
  recorded 
  by 
  Bruner 
  from 
  Canj^ou 
  City, 
  Fremont 
  

   County, 
  Colorado, 
  and 
  the 
  plains 
  of 
  Wyoming. 
  

  

  This 
  species, 
  especiallj' 
  in 
  life, 
  is 
  strikingly 
  different 
  from 
  the 
  next 
  

   two 
  in 
  coloring, 
  though 
  the 
  male 
  abdominal 
  appendages 
  are 
  exceedinglj* 
  

   similar. 
  According 
  to 
  Bruner. 
  it 
  is 
  more 
  clumsj' 
  in 
  its 
  movements 
  than
