  lobes, 
  the 
  front 
  margin 
  subtruncate, 
  the 
  hind 
  margin 
  very 
  obtusely 
  

   ang'ulate, 
  the 
  very 
  coarsely, 
  feebly, 
  and 
  sparsely 
  punctate 
  prozona 
  half 
  

   as 
  long 
  again 
  as 
  the 
  finely 
  and 
  suddenly 
  punctate 
  metazona, 
  its 
  poste- 
  

   rior 
  margin 
  faintly 
  angularly 
  emarginate, 
  the 
  transverse 
  sulci 
  feeble, 
  

   one 
  dividing 
  it 
  into 
  two 
  equal 
  halves 
  and 
  straight, 
  the 
  other 
  a 
  third 
  

   the 
  way 
  behind 
  it 
  to 
  the 
  metazona 
  and 
  sinuate. 
  Prosternal 
  spine 
  erect, 
  

   moderately 
  slender, 
  conical; 
  interspace 
  between 
  mesosternal 
  lobes 
  

   more 
  than 
  twice 
  as 
  long 
  (male), 
  or 
  nearly 
  half 
  as 
  long 
  again 
  (female) 
  as 
  

   its 
  middle 
  breadth, 
  the 
  shape 
  being 
  strongly 
  clepsydral 
  from 
  the 
  con- 
  

   vexity 
  of 
  the 
  inner 
  margin 
  of 
  the 
  lobes, 
  the 
  metasternal 
  lobes 
  subat- 
  

   tingent, 
  especially 
  in 
  the 
  male. 
  Tegmina 
  abbreviate, 
  acuminate, 
  attin- 
  

   gent 
  or 
  overlapping, 
  about 
  as 
  long 
  as 
  the 
  pronotum. 
  Fore 
  and 
  middle 
  

   femora 
  slightly 
  tumid 
  in 
  the 
  male; 
  hind 
  femora 
  slender, 
  somewhat 
  

   compressed, 
  the 
  lower 
  genicular 
  lobe 
  not 
  free 
  from 
  markings, 
  the 
  liiud 
  

   tibiae 
  with 
  nine 
  to 
  ten 
  spines 
  in 
  the 
  outer 
  series. 
  Abdomen 
  of 
  male 
  

   not 
  clavate 
  nor 
  curved 
  upward 
  apically, 
  the 
  lateral 
  margins 
  of 
  the 
  sub- 
  

   genital 
  plate 
  straight 
  from 
  the 
  very 
  base, 
  acutangulate 
  at 
  tip, 
  with 
  a 
  

   slight, 
  blunt, 
  apical 
  tubercle; 
  cerci 
  very 
  slender 
  and 
  simple; 
  fureula 
  

   consisting 
  of 
  a 
  pair 
  of 
  slight 
  cylindrical 
  slender 
  fingers, 
  subparallel 
  or 
  

   more 
  or 
  less 
  crossing 
  one 
  another, 
  perhaps 
  parallel 
  in 
  life. 
  

  

  This 
  genus 
  was 
  established 
  by 
  Brunner 
  upon 
  three 
  species, 
  one 
  of 
  

   which 
  must 
  be 
  referred 
  to 
  J{€S2)erotetiir, 
  since 
  the 
  lateral 
  margins 
  of 
  

   the 
  subgeuital 
  plate 
  are 
  clearly 
  ampliate 
  at 
  the 
  base; 
  while 
  another 
  has 
  

   here 
  been 
  placed 
  in 
  a 
  near 
  and 
  neighboring 
  genus, 
  CaMpylacantJia, 
  

   leaving 
  H. 
  alba 
  as 
  the 
  type 
  and 
  at 
  present 
  the 
  only 
  known 
  member 
  of 
  

   the 
  genus. 
  It 
  is 
  found 
  in 
  our 
  Western 
  States 
  only, 
  east 
  of 
  the 
  Kocky 
  

   Mountains, 
  and 
  from 
  Nebraska 
  southward.
