  the 
  female 
  more 
  or 
  less 
  infiiscated: 
  above 
  the 
  antenna^ 
  brownish 
  

   fuscous, 
  more 
  or 
  less 
  tinged 
  with 
  castaneous: 
  behind 
  the 
  eyes 
  a 
  broad, 
  

   straight, 
  horizontal, 
  black 
  band, 
  edged 
  more 
  or 
  less 
  distinctly, 
  both 
  

   above 
  and 
  below, 
  with 
  yellowish: 
  antennae 
  varying 
  in 
  length, 
  being 
  

   relatively 
  longer 
  in 
  southern 
  than 
  in 
  northern 
  examples, 
  but 
  generally 
  

   about 
  two-thirds 
  as 
  long 
  as 
  the 
  body 
  in 
  the 
  male, 
  yellow 
  at 
  base, 
  

   beyond 
  testaceous, 
  deepening 
  into 
  fuscous 
  toward 
  the 
  tip, 
  the 
  apices 
  

   of 
  the 
  joints 
  normally 
  pallid. 
  Upper 
  surface 
  of 
  the 
  pronotum 
  of 
  the 
  

   color 
  of 
  the 
  top 
  of 
  the 
  head, 
  the 
  upper 
  half 
  of 
  the 
  detieoted 
  lobes 
  with 
  

   a 
  very 
  broad 
  black 
  band 
  in 
  continuation 
  of 
  that 
  on 
  the 
  head, 
  anteriorly 
  

   edged 
  more 
  or 
  less 
  distinctly, 
  both 
  above 
  and 
  below, 
  with 
  yellowish 
  

   and 
  generally 
  fading 
  out 
  before, 
  or 
  abruptly 
  terminating 
  at. 
  the 
  meta- 
  

   zona 
  (in 
  the 
  earlier 
  stages 
  it 
  continues 
  uninterruptedly 
  across 
  the 
  pro- 
  

   notum, 
  and 
  this 
  persistence 
  is 
  occasionally 
  shown 
  in 
  the 
  adult, 
  or 
  is 
  

   indicated 
  on 
  the 
  metazona 
  by 
  a 
  brown 
  band 
  sometimes 
  percurrent 
  and 
  

   usually 
  reduced 
  in 
  width): 
  pleura 
  with 
  a 
  horizontal 
  stigmatal 
  stripe 
  

   running 
  backward 
  from 
  the 
  hinder 
  edge 
  of 
  the 
  mesothoracic 
  episterna 
  

   (sometimes 
  confined 
  to 
  the 
  mesothoracic 
  epimera), 
  and 
  an 
  oblique 
  stripe 
  

   nearly 
  following 
  the 
  division 
  line 
  between 
  the 
  metathoracic 
  episterna 
  

   and 
  epimera; 
  when 
  the 
  lower 
  stripe 
  is 
  complete 
  it 
  renders 
  the 
  meta- 
  

   thoracic 
  episterna 
  conspicuous, 
  especially 
  in 
  the 
  male, 
  on 
  account 
  of 
  

   the 
  cuneiform 
  oblique 
  yellow 
  dash 
  which 
  lies 
  between 
  these 
  two 
  black 
  

   stripes. 
  Hind 
  margin 
  of 
  pronotum 
  less 
  distinctly 
  aiigulate 
  — 
  that 
  is, 
  

   more 
  uniformly 
  rounded 
  — 
  than 
  in 
  the 
  other 
  species, 
  though 
  the 
  ditier- 
  

   ence 
  is 
  but 
  slight 
  and 
  sometimes 
  disappears. 
  Tegmina 
  nearly 
  uniform 
  

   brownish 
  fuscous, 
  often 
  with 
  a 
  fiiint 
  line 
  of 
  small 
  tieckings 
  down 
  the 
  

   middle 
  in 
  the 
  female. 
  Legs 
  of 
  the 
  color 
  of 
  the 
  body, 
  the 
  middle 
  and 
  

   hind 
  femora 
  generally 
  more 
  or 
  less 
  infuscated 
  on 
  their 
  outer 
  face, 
  the 
  

   upper 
  half 
  of 
  the 
  genicular 
  lobes 
  of 
  the 
  latter 
  black 
  : 
  hind 
  tibiae 
  glaucous 
  

   with 
  black 
  or 
  blackish 
  spines. 
  Supraanal 
  plate 
  of 
  male 
  long 
  triangular 
  

   with 
  a 
  broad 
  mesial 
  rounded 
  ridge 
  extending 
  two-thirds 
  its 
  length, 
  ou 
  

   the 
  summit 
  of 
  which, 
  in 
  the 
  basal 
  half 
  of 
  the 
  plate, 
  is 
  a 
  very 
  narrow 
  

   deep 
  sulcus 
  which, 
  after 
  interruption, 
  is 
  repeated 
  again 
  in 
  the 
  apical 
  

   fourth; 
  furcula 
  consisting 
  of 
  a 
  pair 
  of 
  moderately 
  long, 
  moderately 
  

   slender, 
  cylindrical, 
  slightly 
  tapering, 
  blunt^ 
  adjacent 
  fingers 
  (shorter 
  

   than 
  usual 
  in 
  the 
  specimen 
  figiu'ed 
  and 
  drawn 
  too 
  stout), 
  often 
  diver- 
  

   gent: 
  cerci 
  lamellate, 
  very 
  long, 
  strongly 
  incurved, 
  gradually 
  narrow- 
  

   ing 
  and 
  then 
  as 
  gradually 
  enlarging, 
  so 
  as 
  to 
  make 
  the 
  spatulate 
  tip 
  

   nearly 
  as 
  broad 
  as 
  the 
  base, 
  the 
  apical 
  margin 
  rounded 
  and 
  subemar- 
  

   ginate. 
  

  

  The 
  tegmina 
  are 
  ordinarily 
  of 
  about 
  the 
  length 
  of 
  the 
  body, 
  but, 
  in 
  

   the 
  South 
  particularly, 
  it 
  often 
  occurs 
  with 
  tegmina 
  only 
  reaching 
  a 
  

   little 
  beyond 
  the 
  middle 
  of 
  the 
  abdomen. 
  I 
  have 
  seen 
  one 
  such 
  from 
  

   ^lassachusetts; 
  and 
  in 
  a 
  pair 
  from 
  Fort 
  Worth, 
  Texas, 
  in 
  the 
  National 
  

   Museum 
  the 
  tegmina 
  are 
  scarcely 
  longer 
  than 
  the 
  pronotum 
  and 
  sub- 
  

   acuminate 
  at 
  tip. 
  This 
  form 
  may 
  receive 
  the 
  racial 
  name 
  te.rana.
