  removed 
  from 
  the 
  margin, 
  and 
  below 
  the 
  ocellus 
  it 
  is 
  narrowed, 
  sulcate. 
  

   and 
  fails 
  to 
  reach 
  the 
  clypeal 
  suture. 
  Prozoua 
  feebly 
  and 
  sparsely, 
  

   metazona 
  densely 
  and 
  rather 
  strouj^ly, 
  punctate 
  on 
  the 
  disk, 
  the 
  for- 
  

   mer 
  anteriorly 
  with 
  a 
  submarginal 
  transverse 
  series 
  of 
  more 
  distinct 
  

   puncta, 
  becoming 
  mesially 
  a 
  double 
  series; 
  the 
  posterior 
  sulcus 
  of 
  the 
  

   pvozona 
  swerves 
  broadly 
  backward 
  and 
  is 
  completely 
  continuous; 
  that 
  

   in 
  front 
  of 
  it 
  is 
  rather 
  short, 
  not 
  infringing 
  on 
  the 
  hiteral 
  lobes, 
  rigidly 
  

   transverse 
  and 
  feebly 
  continuous. 
  Supraanal 
  plate 
  of 
  male 
  triangular, 
  

   with 
  almost 
  straight 
  lateral 
  margins, 
  subacuminate 
  apex, 
  fully 
  as 
  long- 
  

   as 
  broad, 
  with 
  a 
  pair 
  of 
  submedian, 
  subparallel, 
  rather 
  elevated 
  ridges, 
  

   fading 
  posteriorly, 
  iuclosing 
  a 
  deep 
  median 
  sulcus; 
  furcula 
  consisting 
  

   only 
  of 
  a 
  rather 
  distinct 
  but 
  obtuse 
  angle 
  on 
  either 
  side 
  of 
  a 
  rectangu- 
  

   lar 
  median 
  emargination 
  of 
  the 
  last 
  dorsal 
  segment: 
  cerci 
  very 
  slender 
  

   (slenderer 
  than 
  ai)pears 
  by 
  the 
  tigure), 
  as 
  long 
  as 
  the 
  supraanal 
  plate, 
  

   tapering 
  considerably 
  in 
  the 
  basal 
  half, 
  equal 
  and 
  very 
  feebly 
  incurved 
  

   in 
  the 
  apical 
  half, 
  apical 
  ly 
  blunt 
  ; 
  infracercal 
  plates 
  rather 
  broad, 
  hardly 
  

   narrowing 
  apically, 
  shoiter 
  than 
  the 
  infraanal 
  ])late.

  The 
  tegmina 
  are 
  considerably 
  larger 
  than 
  the 
  abdomen 
  in 
  the 
  male 
  

   from 
  Arizona; 
  somewhat 
  shorter 
  than 
  the 
  abdomen 
  in 
  the 
  female 
  from 
  

   Nevada. 
  I 
  am 
  not 
  at 
  all 
  confident 
  that 
  the 
  two 
  belong 
  together, 
  and 
  

   my 
  description 
  is 
  therefore 
  based 
  almost 
  wholly 
  upon 
  the 
  male.

  Uniform 
  in 
  coloring 
  throughout, 
  and 
  probably 
  testaceous 
  (all 
  speci- 
  

   mens 
  seen 
  have 
  been 
  immersed 
  in 
  alcohol), 
  except 
  that 
  the 
  transverse 
  

   sulci 
  of 
  the 
  pronotum 
  appear 
  to 
  have 
  been 
  marked 
  with 
  bla(;k 
  or 
  fus- 
  

   cous, 
  there 
  are 
  some 
  slight 
  fuscous 
  nuirkings 
  on 
  the 
  upper 
  half 
  of 
  the 
  

   lateral 
  lobes 
  of 
  the 
  prozona, 
  the 
  tegmina 
  are 
  clouded 
  and 
  obscurely 
  

   dotted 
  with 
  fuscous, 
  the 
  hind 
  fe:nora 
  are 
  sometimes 
  twice 
  barred 
  with 
  

   fuscous 
  and 
  have 
  a 
  large 
  fuscous 
  lunule 
  on 
  the 
  geniculation, 
  and 
  the 
  

   tibial 
  spines 
  are 
  black 
  tipped. 
  The 
  eyes 
  of 
  the 
  male 
  are 
  tolerably 
  

   prominent; 
  the 
  fastigium. 
  except 
  at 
  apex, 
  is 
  distinctly 
  and 
  uniformly 
  

   but 
  not 
  deeply 
  sulcate: 
  the 
  frontal 
  costa 
  is 
  subequal, 
  depressed 
  at 
  but 
  

   not 
  sulcate 
  below 
  the 
  ocellus, 
  i)ercurrent. 
  Prozona 
  punctate 
  above 
  

   only 
  in 
  the 
  subnuirginal 
  sulcus; 
  metazona 
  densely 
  and 
  rather 
  strongly 
  

   punctate; 
  posterior 
  sulcus 
  of 
  the 
  prozona 
  oblique 
  on 
  either 
  side, 
  making 
  

   a 
  very 
  open 
  rounded 
  angle 
  mesially, 
  and 
  percurrent, 
  while 
  that 
  next 
  in 
  

   front 
  of 
  it 
  is 
  occasionally 
  subobliterated 
  mesially.
