  Head 
  pallid 
  fuscous, 
  flecked 
  ou 
  the 
  sides 
  with 
  brown 
  and 
  with 
  a 
  

   mediodorsal 
  blackish 
  brown 
  stripe, 
  which 
  fills 
  the 
  narrow 
  sulcus 
  of 
  the 
  

   fastigiuni 
  and 
  passes 
  backward 
  much 
  broadened, 
  continuing 
  with 
  less 
  

   depth 
  of 
  color 
  but 
  with 
  equal 
  width 
  upon 
  the 
  pronotum, 
  as 
  far 
  as 
  the 
  

   posterior 
  limit 
  of 
  the 
  ijrozona; 
  a 
  similar 
  but 
  weaker 
  brown 
  stripe 
  

   passes 
  from 
  behind 
  the 
  eye 
  a 
  similar 
  distance, 
  broader 
  and 
  weaker 
  

   upon 
  the 
  pronotum; 
  antennae 
  pale 
  salmon 
  red, 
  paler 
  at 
  base; 
  frontal 
  

   costa 
  equal, 
  as 
  wide 
  as 
  or 
  slightly 
  wider 
  than 
  the 
  interval 
  between 
  the 
  

   eyes, 
  feebly 
  sulcate 
  below 
  the 
  ocellus; 
  fastigium 
  narrowly 
  and 
  rather 
  

   deeply 
  sulcate, 
  the 
  sulcation 
  of 
  equal 
  width 
  but 
  varying 
  depth. 
  

   Ground 
  color 
  of 
  pronotum 
  yellowish 
  brown, 
  the 
  posterior 
  margin 
  dis- 
  

   tinctly 
  but 
  obtusely 
  and 
  not 
  sharply 
  angulate, 
  the 
  disk 
  of 
  the 
  prozona 
  

   distinctly 
  though 
  but 
  slightly 
  transverse, 
  with 
  no 
  median 
  carina. 
  

   Prosternal 
  spine 
  short, 
  conical, 
  erect. 
  Tegmina 
  considerably 
  surpass- 
  

   ing 
  the 
  abdomen, 
  exceptionally 
  slender, 
  with 
  very 
  slight 
  subbasal 
  

   expansion 
  of 
  the 
  costal 
  area, 
  subacuminate 
  apically, 
  brown, 
  but 
  with 
  

   the 
  larger 
  distal 
  portion 
  pellucid, 
  tlecked 
  with 
  brown 
  by 
  the 
  alternately 
  

   deeper 
  and 
  lighter 
  brown 
  of 
  the 
  veins, 
  the 
  cross- 
  veins 
  mostly 
  white 
  or 
  

   pellucid; 
  wings 
  not 
  much 
  shorter 
  than 
  the 
  tegmina, 
  not 
  very 
  broad, 
  

   the 
  veins 
  blackish 
  brown 
  anteriorly, 
  brownish 
  blue 
  in 
  the 
  anal 
  area. 
  

   Hind 
  femora 
  dull

  with 
  three 
  more 
  or 
  less 
  con- 
  

   fluent, 
  transverse, 
  blackish 
  brown 
  stripes, 
  indicated 
  by 
  transverse 
  fus- 
  

   cous 
  cloudy 
  bars 
  on 
  the 
  upper 
  faces, 
  the 
  arc 
  of 
  the 
  geniculation 
  heavily 
  

   marked 
  in 
  black; 
  hind 
  tibiae 
  pink, 
  becoming 
  gradually 
  plumbeous 
  

   distally, 
  the 
  spines 
  pallid 
  on 
  the 
  basal, 
  black 
  on 
  the 
  apical 
  half. 
  

   Supraanal 
  plate 
  of 
  male 
  subtriangular 
  with 
  sinuous 
  sides 
  and 
  a 
  pro- 
  

   duced 
  and 
  rounded 
  apex, 
  the 
  surface 
  plane 
  or 
  nearly 
  plane, 
  but 
  with 
  

   two 
  pairs 
  of 
  very 
  slight 
  longitudinal 
  ridges, 
  one 
  pair 
  bounding 
  the 
  

   basal 
  median 
  sulcation, 
  which 
  narrows 
  distally 
  and 
  terminates 
  beyond 
  

   the 
  middle 
  of 
  the 
  plate, 
  the 
  other 
  lateral, 
  oblique, 
  and 
  less 
  sharp, 
  prox- 
  

   imally 
  at 
  the 
  lateral 
  margin, 
  distally 
  a 
  little 
  removed 
  from 
  it 
  and 
  ter- 
  

   minating 
  at 
  a 
  similar 
  distance 
  from 
  the 
  base 
  as 
  the 
  other 
  pair; 
  furcula 
  

   barely 
  indicated 
  by 
  an 
  attingent 
  pair 
  of 
  scarcely 
  projecting 
  disks; 
  

   cerci 
  rapidly 
  tapering 
  at 
  base, 
  nearly 
  the 
  entire 
  distal 
  three 
  fifths 
  sub- 
  

   equal, 
  slender, 
  cylindrical, 
  straight, 
  blunt 
  tipped, 
  surpassing 
  slightly 
  

   the 
  length 
  of 
  the 
  supraanal 
  plate; 
  subapical 
  tubercle 
  of 
  subgenital
