  not 
  stout, 
  conico-cyliDdrical; 
  meso- 
  and 
  raetastetliia 
  together 
  iitueli 
  

   longer 
  than 
  broad 
  in 
  both 
  sexes, 
  the 
  latter 
  narrowing 
  rapidly 
  behind, 
  

   so 
  that 
  the 
  portion 
  behind 
  the 
  lobes, 
  more 
  than 
  twice 
  as 
  broad 
  as 
  long, 
  

   is 
  scarcely 
  more 
  than 
  half 
  as 
  broad 
  as 
  the 
  metastethium 
  ; 
  interspace 
  

   between 
  mesosternal 
  lobes 
  much 
  longer 
  than 
  broad 
  in 
  both 
  sexes 
  and 
  

   much 
  narrower 
  than 
  the 
  lobes 
  themselves, 
  the 
  metasternal 
  lobes 
  more 
  

   (male) 
  or 
  less 
  (female) 
  approximate, 
  the 
  interspace 
  in 
  the 
  female 
  scarcely 
  

   so 
  broad 
  as, 
  in 
  the 
  male 
  much 
  narrower 
  than, 
  the 
  frontal 
  costa. 
  Teg- 
  

   miua 
  abbreviate, 
  overlapping, 
  acuminate. 
  Hind 
  femora 
  very 
  long, 
  the 
  

   inferior 
  genicular 
  lobe 
  subpallid, 
  uniform, 
  the 
  hind 
  tibiae 
  Avith 
  eight 
  to 
  

   twelve 
  spines 
  in 
  the 
  outer 
  series. 
  Sides 
  of 
  the 
  first 
  abdominal 
  segment 
  

   with 
  a 
  distinct 
  tympanum. 
  Subgenital 
  plate 
  of 
  male 
  with 
  no 
  apical 
  

   tubercle, 
  its 
  lateral 
  margins 
  ampliate, 
  basally 
  rectangulate; 
  cerci 
  lamel- 
  

   late, 
  subpyriform, 
  tapering 
  strongly 
  and 
  unequally, 
  the 
  apex 
  produced, 
  

   subacuminate 
  and 
  incurved. 
  Abdomen 
  of 
  female 
  regularly 
  tapering, 
  

   the 
  ovipositor 
  normally 
  exserted, 
  the 
  valves 
  nearly 
  straight 
  with 
  acute 
  

   but 
  smooth 
  costae. 
  

  

  The 
  genus 
  is 
  represented 
  by 
  a 
  single 
  species 
  found 
  in 
  the 
  western 
  

   Mississippi 
  valley. 
  When 
  published 
  by 
  Brunner, 
  no 
  species 
  was 
  de- 
  

   scribed 
  or 
  even 
  named, 
  but 
  the 
  species 
  here 
  given 
  is 
  the 
  one 
  upon 
  

   which 
  the 
  genus 
  was 
  founded 
  and 
  is 
  therefore 
  the 
  type.

  distinctly 
  iufuscated 
  ; 
  vertex 
  feebly 
  tumid, 
  

   not 
  elevated 
  above 
  the 
  pronotum, 
  the 
  interspace 
  between 
  the 
  eyes 
  

   exceptionally 
  broad, 
  being 
  nearly 
  four 
  times 
  as 
  broad

  portion 
  of 
  the 
  genae;

   passing 
  by 
  abrupt 
  angles, 
  forming 
  distinct 
  and 
  continuous 
  feebly 
  and 
  

   oppositely 
  arcuate 
  lateral 
  carinae 
  facing 
  inward, 
  into 
  the 
  vertical 
  lateral 
  

   lobes, 
  Avhich 
  above 
  are 
  very 
  steeply 
  and 
  convexly 
  declivont;
