  Specimens 
  from 
  Florida 
  which 
  I 
  formerly 
  referred 
  

   to 
  this 
  species 
  probably 
  belong 
  to 
  the 
  next. 
  

  

  It 
  therefore 
  appears 
  to 
  inhabit 
  the 
  entire 
  United 
  States 
  and 
  the 
  set- 
  

   tled 
  parts 
  of 
  Canada, 
  excepting 
  only 
  Alaska 
  and 
  also 
  the 
  southeastern 
  

   United 
  States 
  (where 
  it 
  is 
  replaced 
  by 
  the 
  next 
  species), 
  and 
  occurs 
  

   south 
  of 
  our 
  border 
  as 
  far 
  as 
  central 
  Mexico. 
  

  

  The 
  species 
  described 
  by 
  me 
  as 
  21. 
  interior 
  was 
  based 
  upon 
  specimens 
  

   from 
  Utah 
  and 
  other 
  parts 
  of 
  the 
  interior 
  of 
  the 
  western 
  country, 
  which 
  

   seem 
  to 
  differ 
  from 
  those 
  found 
  elsewhere 
  in 
  having 
  cerci 
  which 
  taper 
  

   more 
  gradually 
  and 
  show 
  less 
  contrast 
  in 
  the 
  width 
  of 
  the 
  basal 
  and 
  

   apical 
  halves, 
  and 
  at 
  tip 
  are 
  blunter 
  and 
  less 
  manifestly 
  truncate, 
  in 
  

   which 
  also 
  the 
  forks 
  of 
  the 
  furcula 
  are 
  relatively 
  longer 
  and 
  more 
  

   strictly 
  parallel, 
  the 
  tegmina 
  rather 
  shorter 
  and 
  generally 
  lacking 
  any 
  

   macniatiou 
  whatever; 
  the 
  prosternal 
  spine 
  also 
  is 
  more 
  frequently 
  com- 
  

   pressed 
  before 
  the 
  tumid 
  tip; 
  but 
  on 
  comparing 
  a 
  large 
  series 
  of 
  speci- 
  

   mens 
  from 
  these 
  western 
  regions 
  I 
  find 
  it 
  impossible 
  to 
  draw 
  any 
  line 
  

   of 
  demarcation, 
  some 
  specimens 
  having 
  some 
  but 
  not 
  other 
  of 
  these 
  

   characteristics, 
  so 
  that 
  I 
  can 
  only 
  regard 
  the 
  species 
  as 
  in 
  a 
  state 
  of 
  

   flux 
  in 
  this 
  region, 
  preparing, 
  as 
  it 
  were, 
  to 
  divide 
  into 
  distinct 
  races 
  

   not 
  yet 
  clearly 
  enough 
  defined 
  to 
  distinguish 
  them. 
  

  

  1 
  The 
  first 
  three 
  references 
  are 
  doubtful; 
  they 
  probal)ly 
  belong 
  to 
  M. 
  extremus.
