  eleven 
  to 
  twelve, 
  usually 
  eleven, 
  in

   outer 
  series. 
  Extremity 
  of 
  male 
  abdomen 
  strongly 
  clavate, 
  somewhat 
  

   recurved, 
  the 
  supraanal 
  plate 
  long 
  clypeate, 
  with 
  sides 
  strongly 
  com- 
  

   pressed 
  in 
  the 
  middle, 
  the 
  lateral 
  margins 
  strongly 
  elevated, 
  the 
  apex 
  

   acutangulate, 
  the 
  median 
  sulcus 
  very 
  narrow 
  and 
  deep, 
  being 
  a 
  mere 
  

   slit 
  between 
  moderately 
  high 
  but 
  rounded 
  walls, 
  apically 
  obsolete; 
  

   furcula 
  consisting 
  of 
  a 
  pair 
  of 
  basally 
  attingeut, 
  basally 
  expanded, 
  and 
  

   depressed 
  lingers, 
  which 
  beyond 
  are 
  straight, 
  parallel, 
  acuminate 
  

   thorns, 
  more 
  than 
  a 
  third 
  as 
  long 
  as 
  the 
  supraanal 
  plate 
  and 
  overlying 
  

   its 
  ridges; 
  cerci 
  coarse 
  and 
  heavy 
  subfalciform 
  laminae, 
  their 
  plane 
  

   obliquely 
  vertical 
  and 
  nearly 
  straight, 
  considerably 
  shorter 
  than 
  the 
  

   supraanal 
  plate, 
  tapering 
  considerably 
  on 
  the 
  basal 
  half, 
  feebly 
  on 
  the 
  

   apical 
  half, 
  which 
  is 
  considerably 
  more 
  than 
  half 
  as 
  broad 
  as 
  the 
  

   extreme 
  base, 
  obhquely 
  truncate 
  at 
  apex, 
  the 
  upper 
  angle 
  very 
  blunt; 
  

   subgenital 
  plate 
  narrowing 
  from 
  base 
  to 
  apex, 
  somewhat 
  longer 
  than 
  

   broad, 
  the 
  lateral 
  margins 
  gently 
  sinuate, 
  the 
  apical 
  margin 
  elevated 
  

   by 
  slight 
  tubercles 
  at 
  its 
  somewhat 
  angular 
  junction 
  with 
  the 
  lateral 
  

   margins, 
  so 
  that 
  it 
  is 
  broadly 
  notched, 
  as 
  viewed

  The 
  species 
  is 
  very 
  closely 
  allied 
  to 
  the 
  last, 
  but 
  differs 
  from 
  it 
  dis- 
  

   tinctly 
  in 
  the 
  character 
  of 
  the 
  subgenital 
  plate.

  CINEREUS 
  SERIES. 
  

  

  In 
  this 
  more 
  than 
  usually 
  homogeneous 
  group, 
  the 
  male 
  prozona 
  is 
  

   quadrate 
  or 
  slightly 
  longitudinal, 
  and 
  the 
  intersi)ace 
  between 
  the 
  

   mesosternal 
  lobes 
  of 
  the 
  same 
  sex 
  varies 
  from 
  a 
  little 
  longer 
  than 
  broad 
  

   to 
  twice 
  as 
  long 
  as 
  broad. 
  The 
  tegmina 
  are 
  always 
  fully 
  developed, 
  

   surpassing 
  somewhat 
  the 
  hind 
  femora, 
  and 
  at 
  most 
  are 
  feebly 
  maculate, 
  

   the 
  flecking 
  not 
  always 
  confined 
  closely 
  to 
  the 
  discoidal 
  area. 
  The 
  

   hind 
  tibiae 
  are 
  blue 
  or 
  green 
  (in 
  one 
  instance 
  apparently 
  reddish 
  yellow) 
  

   and 
  have 
  ten 
  to 
  twelve 
  spines 
  in 
  the 
  outer 
  series.
