  equal 
  sections 
  by 
  a 
  distinct, 
  longitudinal, 
  median 
  carina 
  that 
  extends 
  back 
  part 
  way 
  

   upon 
  the 
  occiput 
  ; 
  sides 
  of 
  the 
  foyeola 
  parallel 
  between 
  the 
  eyes, 
  and 
  bending 
  abruptly 
  

   inward 
  toward 
  the 
  fastigium, 
  in 
  front, 
  continuous 
  with 
  the 
  sides 
  of 
  the 
  frontal 
  costa 
  ; 
  

   fastigium 
  with 
  a 
  double 
  indentation. 
  Frontal 
  costa 
  slightly 
  sulcate, 
  sub-tricarinate 
  

   at 
  the 
  fastigium, 
  widening 
  at 
  the 
  ocellus 
  and 
  extending 
  nearly 
  or 
  quite 
  totheclypeus, 
  

   but 
  not 
  expanding 
  below 
  ; 
  in 
  the 
  $ 
  the 
  width 
  is 
  almost 
  uniform 
  throughout. 
  Pro- 
  

   notum, 
  with 
  the 
  median 
  carina 
  sub-cristate, 
  distinctly 
  and 
  deeply 
  notched 
  about 
  the 
  

   middle 
  by 
  the 
  posterior 
  sulcus 
  ; 
  anterior 
  portion 
  irregularly 
  arched, 
  more 
  elevated 
  than 
  

   the 
  posterior 
  portion, 
  which 
  has 
  only 
  the 
  front 
  part 
  arched 
  ; 
  lateral 
  carinas 
  irregular 
  

   and 
  indistinct 
  ; 
  the 
  notch 
  of 
  the 
  median 
  carina 
  is 
  of 
  the 
  oblique 
  type, 
  more 
  distinctly 
  

   so 
  in 
  the 
  male 
  than 
  in 
  the 
  female. 
  Posterior 
  lobe 
  expanding 
  rapidly 
  from 
  the 
  posterior 
  

   sulcus, 
  nearly 
  flat 
  on 
  the 
  disk, 
  which 
  is 
  more 
  or 
  less 
  covered 
  with 
  elongate 
  rugosities, 
  

   more 
  distinct 
  and 
  numerous 
  in 
  the 
  female 
  than 
  in 
  the 
  male 
  ; 
  posterior 
  extremity 
  ob- 
  

   tuse-angled 
  ; 
  anterior 
  margin 
  extended 
  in 
  a 
  very 
  obtuse 
  angle 
  upon 
  the 
  occiput. 
  Ely- 
  

   tra 
  extending 
  about 
  one-third 
  their 
  length 
  beyond 
  the 
  abdomen, 
  of 
  medium 
  width, 
  

   sinuous 
  and 
  obliquely 
  excised 
  at 
  the 
  tip. 
  Wings 
  narrow, 
  the 
  length 
  very 
  nearly 
  twice 
  

   the 
  width, 
  and 
  slightly 
  undulate 
  on 
  the 
  outer 
  margin 
  ; 
  the 
  nervules 
  unusually 
  regular 
  

   and 
  straight. 
  Posterior 
  femora 
  with 
  sharp 
  and 
  elevated 
  carinas 
  above 
  and 
  below. 
  

   Antennae 
  rather 
  short, 
  scarcely 
  flattened, 
  and 
  very 
  slightly 
  acuminate 
  at 
  the 
  tip. 
  

  

  Color 
  (recent 
  specimens 
  dried). 
  — 
  Female 
  somewhat 
  darker 
  than 
  the 
  male 
  ; 
  face 
  pale 
  

   purplish, 
  dotted 
  with 
  fuscous 
  ; 
  occiput 
  and 
  pronotum 
  fuscous 
  brown, 
  the 
  latter 
  with 
  

   a 
  carneous 
  stripe 
  along 
  each 
  lateral 
  carina, 
  which 
  connect 
  at 
  the 
  anterior 
  sulcus 
  and 
  

   fade 
  out 
  near 
  the 
  posterior 
  extremity 
  ; 
  the 
  disk 
  of 
  the 
  posterior 
  lobe 
  dark 
  brown. 
  

   Elytra 
  pale, 
  dirty 
  yellow, 
  slightly 
  tinged 
  with 
  rufous, 
  crossed 
  by 
  three 
  irregular 
  bands 
  

   formed 
  of 
  dark 
  fuscous 
  spots, 
  the 
  middle 
  one 
  broadest 
  and 
  usually 
  the 
  best 
  defined 
  ; 
  

   apex 
  with 
  irregular, 
  cellular, 
  fuscous 
  spots, 
  those 
  next 
  the 
  costal 
  margin 
  most 
  distinct. 
  

   Wings 
  pellucid, 
  with 
  a 
  narrow 
  marginal, 
  rather 
  pale, 
  fuscous 
  band, 
  commencing 
  be- 
  

   hind 
  the 
  sub-costal 
  area, 
  where 
  it 
  is 
  broadest, 
  narrowing 
  and 
  fading 
  toward 
  the 
  anal 
  

   angle 
  ; 
  the 
  nerves 
  and 
  nervules, 
  except 
  in 
  the 
  apical 
  portion 
  of 
  the 
  sub-costal 
  area 
  

   and 
  in 
  the 
  fuscous 
  band, 
  pale 
  yellow, 
  or 
  white. 
  Posterior 
  femora 
  crossed 
  externally 
  

   and 
  internally 
  by 
  three 
  oblique 
  fuscous 
  bands 
  ; 
  posterior 
  tibiae 
  pale 
  yellow 
  ; 
  spines 
  

   tipped 
  with 
  black. 
  

  

  One 
  male 
  and 
  one 
  female 
  from 
  Sierra 
  Valley, 
  California, 
  furnished 
  by 
  Mr. 
  J. 
  G. 
  

   Lemmon. 
  

  

  This 
  species 
  approaches 
  very 
  near 
  Mr. 
  Scudder's 
  Trachyrhachys, 
  but 
  appears 
  to 
  belong 
  

   to 
  (Edipoda, 
  as 
  at 
  present 
  limited. 
  If 
  Mr. 
  Scudder's 
  genus 
  Dissosteira 
  (of 
  which 
  he 
  has 
  

   given 
  but 
  an 
  incomplete 
  diagnosis) 
  stands, 
  this 
  species 
  will 
  scarcely 
  find 
  a 
  lodging- 
  

   place 
  in 
  any 
  of 
  the 
  numerous 
  genera 
  of 
  this 
  group. 
  

  

  In 
  his 
  paper 
  on 
  the 
  Orthoptera 
  collected 
  by 
  Lieutenant 
  Wheeler's 
  survey, 
  published 
  

   in 
  1876, 
  where 
  he 
  first 
  proposes 
  this 
  genus, 
  he 
  makes 
  the 
  following 
  statement 
  : 
  " 
  Stal's 
  

   limitations 
  of 
  the 
  genus 
  (Edipoda, 
  in 
  his 
  Recensio 
  Orthopt. 
  I, 
  forces 
  us 
  to 
  consider 
  Ch-yU 
  

   lus 
  coerulescens, 
  Linn, 
  as 
  the 
  type, 
  and 
  not, 
  as 
  stated 
  by 
  Thomas, 
  (Edipoda 
  Carolina 
  

   (Burm)." 
  

  

  He 
  alludes 
  to 
  a 
  statement 
  made 
  in 
  my 
  paper 
  on 
  Orthoptera, 
  in 
  a 
  previous 
  report 
  of 
  

   the 
  same 
  survey, 
  where 
  I 
  simply 
  remark 
  that 
  Stal 
  has 
  retained 
  our 
  (E. 
  Carolina, 
  and 
  

   that 
  "this 
  appears 
  to 
  &e-his 
  typical 
  [species]" 
  (by 
  typographical 
  or 
  clerical 
  error 
  

   "genus"). 
  By 
  reference 
  to 
  Proceedings 
  Davenport 
  Acad. 
  Nat. 
  Sci., 
  vol. 
  i, 
  1876, 
  page 
  

   257, 
  it 
  will 
  there 
  be 
  seen 
  that 
  I 
  make 
  the 
  following 
  statement 
  in 
  reference 
  to 
  the 
  genus 
  

   (Edipoda 
  as 
  given 
  by 
  Stal 
  : 
  "In 
  my 
  opinion 
  (E. 
  coerulescens, 
  Linn, 
  is 
  the 
  proper 
  type 
  of 
  

   (Edipoda." 
  This 
  paper 
  was 
  published 
  in 
  June 
  and 
  July, 
  1876, 
  the 
  entire 
  manuscript 
  

   having 
  been 
  forwarded 
  to 
  Mr. 
  Putnam 
  some 
  time 
  previous 
  thereto. 
  I 
  cannot 
  give 
  the 
  

   exact 
  date 
  of 
  publication 
  of 
  Mr. 
  Scudder's 
  paper, 
  but 
  his 
  letter 
  of 
  transmittal 
  to 
  Lieu- 
  

   tenant 
  Wheeler 
  bears 
  date 
  Cambridge, 
  Mass., 
  May 
  29, 
  1876. 
  

  

  I 
  simply 
  mention 
  this 
  in 
  j 
  ustico 
  to 
  myself. 
  

  

  As 
  I 
  have 
  here 
  referred 
  to 
  this 
  paper 
  by 
  Mr. 
  Scudder 
  I 
  may 
  as 
  well 
  correct 
  another
