  Abdomen

  : 
  Very 
  strongly 
  compressed, 
  its 
  upper 
  

   margin 
  serrate 
  in 
  profile 
  due 
  to 
  the 
  heavily 
  sclerotized 
  and 
  acute 
  

   apices 
  of 
  the 
  compressed 
  tergites; 
  segments

  another 
  genus

  the 
  arid 
  southwestern 
  part 
  of 
  the 
  United 
  

   States, 
  being 
  represented 
  there 
  by 
  five 
  or 
  six 
  species, 
  of 
  which 
  only 
  

   the 
  genotype 
  is

  I 
  have 
  examined 
  the 
  types 
  of 
  both 
  costalis 
  and 
  gilletti 
  and 
  have 
  seen 
  

   three 
  additional 
  specimens, 
  a 
  male

  Colorado 
  (C.

  a 
  

   female

  differing
