  In 
  tbis 
  small 
  and 
  compact 
  group 
  the 
  prozona 
  of 
  the 
  male 
  is 
  longitu- 
  

   dinal, 
  and 
  the 
  interspace 
  between 
  the 
  niesosternal 
  lobes 
  in 
  the 
  same 
  

   sex 
  longer 
  than 
  broad, 
  sometimes 
  twice 
  as 
  long 
  as 
  broad. 
  The 
  anten- 
  

   nae 
  are 
  rather 
  short. 
  The 
  tegmina 
  are 
  but 
  little 
  longer 
  than 
  the 
  pro- 
  

   notnm, 
  overlapping, 
  and 
  apically 
  acuminate. 
  The 
  hind 
  tibiae 
  are 
  glau- 
  

   cous 
  (or 
  pale 
  red) 
  with 
  nine 
  to 
  twelve 
  (normally 
  ten) 
  spines 
  in 
  the 
  ouler 
  

   series. 
  

  

  The 
  supraanal 
  plate 
  is 
  subtriangular, 
  with 
  rather 
  plane 
  surface, 
  

   except 
  for 
  the 
  rather 
  prominent 
  ridges 
  bordering 
  and 
  forming 
  between 
  

   them 
  the 
  median 
  sulcus; 
  the 
  furcula 
  consists 
  of 
  a 
  pair 
  of 
  pointed 
  slen- 
  

   der 
  teeth 
  but 
  little 
  longer 
  than 
  tlie 
  last 
  dorsal 
  segment; 
  the 
  cerci 
  are 
  

   very 
  peculiar, 
  enlarging 
  and 
  bullate 
  beyond 
  the 
  base, 
  but 
  with 
  angu- 
  

   lar 
  margins, 
  sulcate 
  inferiorly, 
  compressed 
  but 
  longitudinally 
  convex 
  

   exteriorly, 
  abruptly 
  narrowing 
  beyond 
  the 
  middle 
  and 
  incurved, 
  ending 
  

   in 
  a 
  superior, 
  short, 
  flattened 
  finger 
  directed 
  toward 
  the 
  tip 
  of 
  the 
  

   .supraanal 
  plate; 
  the 
  subgenital 
  plate 
  is 
  very 
  short 
  and 
  apically 
  very 
  

   broad, 
  subconical, 
  with 
  a 
  strongly 
  and 
  abruptly 
  elevated 
  though 
  

   laterally 
  brief 
  ai)ical 
  margin. 
  

  

  The 
  three 
  species 
  belonging 
  here 
  are 
  rather 
  bulky 
  iuvsects, 
  rather 
  

   above 
  the 
  medium 
  size 
  for 
  the 
  genus, 
  and 
  they 
  range 
  from 
  southwestern 
  

   Nebraska 
  and 
  Colorado 
  to 
  central 
  Mexico.
