  Bruner 
  in 
  an 
  unpublished 
  account 
  of 
  this 
  species 
  gives 
  its 
  habitat 
  as 
  

   *'in 
  the 
  mountains 
  near 
  Ogden,Utah, 
  among 
  the 
  low 
  trees 
  and 
  bushes, 
  

   at 
  an 
  elevation 
  slightly 
  above 
  the 
  highest 
  of 
  the 
  ancient 
  shore 
  lines 
  of 
  

   Salt 
  Lake; 
  also 
  among 
  the 
  foothills 
  of 
  the 
  Big 
  Horn 
  Mountains, 
  near 
  

   Fort 
  McKinney, 
  Wyoming." 
  

  

  In 
  the 
  same 
  manuscript, 
  Bruner 
  compares 
  the 
  present 
  species 
  with 
  

   M. 
  aflanis, 
  as 
  follows 
  : 
  

  

  Closely 
  related 
  to 
  M. 
  atlavis 
  in 
  many 
  respects 
  ; 
  from 
  wliirli 
  it 
  is 
  to 
  be 
  tlistiuguisbed 
  

   liy 
  its 
  somewhat 
  larger 
  size 
  and 
  more 
  robust 
  form, 
  also 
  by 
  its 
  larger 
  bead 
  and 
  more 
  

   promiiieut 
  eyes. 
  The 
  last 
  ventral 
  segment 
  [subgenital 
  plate] 
  of 
  the 
  male 
  is 
  shorter 
  

   and 
  the 
  male 
  cerci 
  are 
  narrower 
  than 
  in 
  the 
  typical 
  atlanis. 
  The 
  color 
  of 
  the 
  hind 
  

   tibiae 
  is 
  pale 
  glaucous 
  as 
  in 
  hifermedius 
  instead 
  of 
  red, 
  as 
  is 
  usually 
  the 
  case 
  in 
  

   typical 
  specimens 
  of 
  atlanis.

  A 
  medium-sized 
  or 
  rather 
  small 
  species,

  flecked 
  with 
  fuscous 
  above, 
  or 
  wholly 
  

   infuscated, 
  with 
  a 
  broad 
  ])iceous 
  or 
  fuscous 
  postocular 
  band; 
  vertex 
  

   gently 
  tumid, 
  a 
  little 
  (sometimes 
  considerably) 
  elevated 
  above 
  the 
  level 
  

   of 
  the 
  pronotum, 
  tlie 
  interspace 
  between 
  the 
  eyes 
  fully 
  half 
  as 
  broad 
  

   again 
  as 
  the 
  first 
  antenna! 
  joint, 
  slightly 
  broader 
  in 
  the 
  female 
  than
