  portion 
  of 
  the 
  genae; 
  antennae 
  red, 
  infnscated 
  apically. 
  Pronotum 
  

   snbeqnal, 
  scarcely 
  expanding 
  posteriorly 
  even 
  in 
  the 
  female, 
  the 
  front 
  

   margin 
  subtrnucate, 
  the 
  hind 
  margin 
  broadly 
  angulate, 
  the 
  angle 
  

   rounded; 
  disk 
  very 
  feebly 
  convex 
  and 
  separated 
  by 
  snbdistinct 
  lateral 
  

   carinae 
  formed 
  of 
  a 
  rounded 
  angle 
  from 
  the 
  subvertical 
  lateral 
  lobes, 
  

   the 
  median 
  carina 
  distinct 
  but 
  slight 
  on 
  the 
  metazona, 
  feeble 
  on 
  the 
  

   prozona, 
  sometimes 
  subobsolete 
  between 
  the 
  sulci 
  ; 
  prozona 
  smooth, 
  dis- 
  

   tinctly 
  longitudinal 
  (male) 
  or 
  subtrausverse 
  (female), 
  a 
  third 
  (male) 
  or 
  

   scarcely 
  (female) 
  longer 
  than

  finely 
  and 
  closel}' 
  punctate 
  metazona. 
  the 
  

   principal 
  sulcus 
  between 
  them 
  straight; 
  without 
  lighter 
  markings 
  at 
  

   the 
  lateral 
  carinae, 
  the 
  lateral 
  lobes 
  more 
  or 
  less 
  but 
  feebly 
  discolored, 
  

   the 
  posterior 
  lobe 
  of 
  the 
  prozona 
  usually 
  the 
  darker. 
  Prosternal 
  spine 
  

   rather 
  long, 
  moderately 
  stout, 
  subcylindrical, 
  blunt, 
  a 
  little 
  retrorse. 
  

   Tegmina 
  surpassing 
  the 
  hind 
  femora, 
  rather 
  slender, 
  tapering 
  very 
  

   feebly, 
  brownish 
  testaceous 
  without 
  longitudinal 
  stripes. 
  Fore

   middle 
  femora 
  plumbeo 
  olivaceous,

   femora 
  brown 
  or

  olivaceous 
  on 
  the

   dull 
  flavous 
  beneath 
  and 
  on 
  the 
  inner 
  side, 
  but 
  on 
  the 
  latter 
  more 
  or 
  

   less 
  interrupted 
  with 
  fuscous 
  above, 
  the 
  genicular 
  arc 
  brownish 
  tes- 
  

   taceous; 
  hind 
  tibiae 
  wholly 
  coral 
  red, 
  the 
  spines 
  black 
  almost 
  to 
  tlie 
  

   base, 
  ten 
  to 
  twelve 
  in 
  number 
  in 
  the 
  outer 
  series. 
  Extremity 
  of 
  male 
  

   abdomen 
  feebly 
  clavate, 
  upturned, 
  the 
  supraanal 
  plate 
  triangular 
  with 
  

   gently 
  sinuate 
  margins, 
  subrectangulate 
  apex, 
  nearly 
  flat, 
  with 
  a 
  very 
  

   broad 
  and 
  obscure, 
  feebly 
  percurrent, 
  longitudinal 
  sulcus, 
  bounded 
  by 
  

   low 
  broad 
  walls, 
  a 
  little 
  constricted 
  in 
  the 
  apical 
  half; 
  furcula 
  consist- 
  

   ing 
  of 
  a 
  pair 
  of 
  slight 
  acuminate 
  denticulations, 
  arising 
  from 
  the 
  thick- 
  

   ened 
  inner 
  extremities 
  of 
  the 
  divided 
  halves 
  of 
  the 
  last 
  dorsal 
  seg- 
  

   ment, 
  and 
  overlying 
  the 
  ridges 
  bounding 
  the 
  median 
  sulcus 
  of 
  the 
  

   sui)raanal 
  plate; 
  cerci 
  large 
  and 
  broad, 
  gently 
  incurved, 
  slightly 
  taper- 
  

   ing 
  on 
  the 
  basal 
  half, 
  and 
  then 
  expanding 
  into 
  a 
  transversely 
  suboval 
  

   apical 
  flabellation, 
  nearly 
  half 
  as 
  broad 
  again 
  as 
  the 
  extreme 
  base, 
  

   expanding 
  more 
  above 
  than 
  below, 
  the 
  apical 
  margin 
  broadly 
  convex, 
  

   the 
  whole 
  considerably 
  surpassing 
  the 
  supraanal 
  plate; 
  infracercal 
  

   plates 
  surpassing 
  but 
  slightly 
  the 
  sides 
  of 
  the 
  supraanal 
  plate, 
  about 
  as 
  

   long 
  as 
  it; 
  subgenital 
  plate 
  moderately 
  broad, 
  the 
  lateral 
  margins 
  

   hardly 
  elevated 
  apically, 
  but 
  considerably 
  prolonged, 
  subtuberculate.

  This 
  is 
  the 
  smallest

  PUNCTULATUS 
  SEPvIES. 
  

  

  This 
  group 
  is 
  composed 
  of 
  species 
  with 
  prominent 
  head 
  and 
  rapidly 
  

   declivent 
  fastigium, 
  and, 
  in 
  the 
  male, 
  very 
  prominent 
  eyes. 
  The 
  joints 
  

   of 
  the 
  antennae 
  are 
  unusually 
  long. 
  The 
  pronotum 
  is 
  rather 
  short 
  and
