  REVISION

  or 
  less, 
  generally 
  rather 
  vaguely, 
  maculate 
  or 
  blotched. 
  The 
  hind 
  

   tibiae 
  are 
  either 
  red 
  or 
  green, 
  usually 
  the 
  former, 
  and 
  have 
  ten 
  to 
  four- 
  

   teen 
  spines 
  in 
  the 
  outer 
  series. 
  

  

  The 
  supraanal 
  plate 
  is 
  pretty 
  regularly 
  triangular, 
  the 
  apex 
  never 
  

   obtusangulate 
  and 
  generally 
  has 
  a 
  median 
  transverse 
  ridge 
  of 
  greater 
  

   or 
  less 
  distinctness. 
  The 
  furcula 
  is 
  generally 
  a 
  mere 
  triangular 
  tooth 
  

   shorter 
  than 
  the 
  last 
  dorsal 
  segment, 
  but 
  in 
  one 
  species 
  is 
  wanting 
  and 
  

   in 
  others 
  forms 
  a 
  pair 
  of 
  slender 
  spines 
  a 
  little 
  longer 
  than 
  the 
  last 
  

   dorsal 
  segment. 
  The 
  cerci 
  are 
  of 
  moderate 
  width 
  and 
  invariably 
  forked 
  

   more 
  or 
  less 
  distinctly, 
  sometimes 
  the 
  upper, 
  sometimes 
  the 
  lower 
  fork 
  

   the 
  longer, 
  or 
  they 
  have 
  a 
  strongly 
  angulate 
  median 
  process 
  beneath, 
  

   which 
  stands 
  for 
  an 
  inferior 
  branch. 
  The 
  subgenital 
  plate 
  is 
  variable, 
  

   but 
  is 
  generally 
  rather 
  broad 
  (but 
  sometimes 
  very 
  narrow) 
  and 
  gener- 
  

   ally 
  a 
  little, 
  in 
  one 
  species 
  greatly, 
  elevated 
  apically. 
  

  

  The 
  species, 
  nine 
  in 
  number, 
  are 
  of 
  small 
  or 
  medium 
  size, 
  occasion- 
  

   ally 
  a 
  little 
  above 
  the 
  medium. 
  Some 
  species 
  or 
  other 
  of 
  the 
  group 
  has 
  

   been 
  reported 
  from 
  every 
  i^art 
  of 
  the 
  United 
  States 
  excepting 
  Alaska 
  

   and 
  California, 
  and 
  is 
  known 
  also 
  from 
  the 
  immediately 
  neighboring- 
  

   parts 
  of 
  the 
  Dominion 
  of 
  Canada 
  west 
  of 
  the 
  Great 
  Lakes, 
  but 
  none 
  

   have 
  been 
  reported 
  from 
  Ontario 
  or 
  Quebec, 
  where 
  they 
  doubtless 
  

   exist, 
  nor 
  from 
  the 
  Lower 
  Mississippi 
  Valley, 
  where 
  they 
  also 
  probably 
  

   occur; 
  nor 
  is 
  a 
  single 
  species 
  known 
  from 
  any 
  j)art 
  of 
  Mexico.
