  Tvitli 
  fuscous 
  clots 
  of 
  greater 
  or 
  less 
  depth 
  and 
  distinetuess 
  throughout 
  

   the 
  greater 
  part 
  of 
  the 
  discoidal 
  area, 
  but 
  rarely 
  to 
  any 
  considerable 
  

   extent 
  or 
  conspicuousuess 
  beyond 
  the 
  middle; 
  wings 
  moderately 
  broad, 
  

   hyaline, 
  glistening, 
  with 
  fuscous 
  veins 
  and 
  cross 
  veins 
  darkest 
  apically 
  

   and 
  anteriorly. 
  Thoracic 
  pleura 
  piceous 
  or 
  blackish 
  fuscous, 
  the 
  meta- 
  

   thoracic 
  episterua 
  with 
  a 
  mesial 
  streak 
  of 
  flavous 
  of 
  greater 
  or 
  less 
  

   clarity. 
  Fore 
  and 
  middle 
  femora 
  distinctly 
  but 
  not 
  greatly 
  tumid 
  in 
  

   the 
  male; 
  hind 
  femora 
  olivaceo-testaceous, 
  more 
  or 
  less 
  heavily 
  and 
  

   very 
  variably 
  obscured 
  or 
  clouded 
  with 
  fuscous, 
  the 
  fuscous 
  coloring 
  

   generally 
  confined 
  to 
  the 
  upper 
  half, 
  and 
  above 
  generally 
  concentrated 
  

   in 
  two 
  fasciae, 
  which 
  sometimes 
  extend 
  partly 
  in 
  an 
  oblique 
  direction 
  

   on 
  the 
  outer 
  face, 
  but 
  generally 
  in 
  a 
  very 
  obscure 
  fashion, 
  if 
  at 
  all, 
  

   while 
  the 
  whole 
  under 
  surface 
  and 
  at 
  least 
  the 
  basal 
  half 
  of 
  the 
  inner 
  

   surface 
  is 
  more 
  or 
  less 
  impure 
  flavous, 
  sometimes 
  deepening, 
  especially 
  

   beneath, 
  to 
  ferruginous 
  or 
  even 
  carmine; 
  hind 
  tibiae 
  normally 
  red, 
  

   sometimes 
  with 
  a 
  slight 
  fuscous 
  patellar 
  spot, 
  occasionally 
  more 
  or 
  

   less 
  tinged 
  with 
  yellowish, 
  very 
  rarely 
  pale 
  green 
  with 
  a 
  yellowish 
  

   tinge, 
  the 
  spines 
  black 
  nearly 
  to 
  their 
  base, 
  ten 
  to 
  thirteen, 
  usually 
  

   eleven, 
  in 
  number 
  in 
  the 
  outer 
  series. 
  Extremity 
  of 
  male 
  abdomen 
  

   rather 
  strongly 
  clavate, 
  well 
  recurved, 
  the 
  supraanal 
  plate 
  clypeate, 
  

   strongly 
  and 
  rather 
  abruptly 
  contracted 
  mesially, 
  the 
  apex 
  subrect- 
  

   angulate, 
  the 
  lateral 
  margins 
  elevated, 
  the 
  ajjical 
  portion 
  more 
  or 
  less 
  

   deflexed, 
  the 
  median 
  sulcus 
  rather 
  large, 
  not 
  very 
  deep, 
  bounded 
  by 
  

   moderate 
  but 
  rather 
  abrupt 
  walls, 
  apically 
  expanding 
  and 
  obsoles- 
  

   cent; 
  furcula 
  consisting 
  of 
  a 
  pair 
  of 
  subparallel 
  or 
  sometimes 
  feebly 
  

   divergent, 
  tapering, 
  subacuminate, 
  apically 
  well 
  separated, 
  more 
  or 
  

   less 
  feebly 
  depressed 
  fingers, 
  falling 
  a 
  little 
  short 
  of 
  the 
  middle 
  of 
  the 
  

   supraanal 
  plate, 
  and 
  except 
  at 
  extreme 
  base 
  lying 
  on 
  the 
  outer 
  side 
  of 
  

   the 
  ridges 
  bounding 
  its 
  median 
  sulcus; 
  cerci 
  rudely 
  subfalciform, 
  com- 
  

   pressed 
  laminae, 
  tapering 
  considerably 
  and 
  rather 
  rapidly 
  from 
  base 
  to 
  

   middle, 
  beyond 
  that 
  subequal 
  but 
  apically 
  very 
  obliquely 
  truncate, 
  so 
  

   that 
  the 
  upper 
  angle 
  is 
  considerably 
  produced 
  but 
  blunt, 
  the 
  whole 
  

   somewhat 
  incurved 
  and 
  failing 
  to 
  reach 
  the 
  tip 
  of 
  the 
  supraanal 
  plate; 
  

   infracercal 
  plates 
  exceedingly 
  broad 
  at 
  base, 
  extending 
  laterally 
  far 
  

   beyond 
  the 
  sides 
  of 
  the 
  cerci, 
  as 
  long 
  as 
  the 
  supraanal 
  plate; 
  subgeni- 
  

   tal 
  plate 
  very 
  short 
  apically 
  so 
  as 
  to 
  be 
  less 
  than 
  half 
  the 
  breadth 
  of 
  

   the 
  base, 
  the 
  lower 
  margin 
  straight, 
  the 
  lateral 
  margin 
  very 
  sinuous, 
  

   the 
  apical 
  margin 
  not 
  elevated, 
  strongly 
  rounded, 
  entire.
