  It 
  has 
  also 
  been 
  reported 
  from 
  Quebec 
  (Provancher, 
  Scudder), 
  Dodge 
  

   County, 
  Nebraska 
  (Dodge), 
  and 
  the 
  Mackenzie 
  River, 
  British 
  America, 
  

   at 
  latitude 
  65° 
  (Kirby); 
  the 
  last, 
  however, 
  is 
  uncertain, 
  dependingon 
  the 
  

   determination 
  of 
  Kirby's 
  species. 
  It 
  probably 
  occurs 
  throughout 
  the 
  

   larger 
  part 
  of 
  Canada 
  and 
  the 
  northernmost 
  United 
  States. 
  

  

  As 
  indicated 
  in 
  the 
  description, 
  this 
  insect 
  appears 
  in 
  two 
  forms: 
  a 
  

   short 
  winged 
  {M. 
  e. 
  Junius), 
  in 
  which 
  the 
  tegmina 
  at 
  rest 
  do 
  not 
  reach 
  

   the 
  tips 
  of 
  the 
  hind 
  femora; 
  and 
  a 
  long-winged 
  (for 
  which 
  I 
  propose 
  

   the 
  name 
  31. 
  e. 
  scandens), 
  in 
  which 
  they 
  surpass 
  them, 
  generally 
  con- 
  

   siderably. 
  The 
  latter 
  has 
  also 
  a 
  slightly 
  slenderer 
  body, 
  though 
  the 
  

   difference 
  is 
  not 
  marked. 
  It 
  appears 
  to 
  affect 
  high 
  latitudes 
  and 
  alti- 
  

   tudes, 
  being 
  found 
  in 
  all 
  the 
  localities 
  in 
  the 
  high 
  north 
  where 
  Kennicott 
  

   collected, 
  on 
  the 
  Big 
  Horn 
  Mountains 
  in 
  Wyoming, 
  and 
  on 
  the 
  summits 
  

   of 
  Greylock 
  in 
  Massachusetts, 
  and 
  the 
  White 
  Mountaiusin 
  New 
  Hamp- 
  

   shire, 
  in 
  all 
  of 
  which 
  (unless 
  in 
  Wyoming, 
  whence 
  I 
  have 
  only 
  seen 
  two 
  

   specimens) 
  it 
  is 
  the 
  i)revailing 
  or 
  exclusive 
  form. 
  The 
  short-winged 
  

   form, 
  however, 
  occurs 
  in 
  all 
  these 
  places 
  excepting 
  the 
  Alpine 
  region 
  of 
  

   the 
  White 
  Mountains, 
  where 
  it 
  has 
  not 
  been 
  taken 
  ; 
  and 
  the 
  long 
  winged 
  

   occurs 
  also 
  at 
  lower 
  levels 
  in 
  New 
  England, 
  as 
  at 
  North 
  Conway, 
  New 
  

   Hampshire, 
  Jay 
  and 
  Montgomery, 
  Vermont, 
  and 
  Winchendon, 
  Massa- 
  

   chusetts, 
  but 
  it 
  is 
  only 
  found 
  in 
  these 
  places 
  exceptionally, 
  to 
  judge 
  

   from 
  the 
  specimens 
  seen. 
  The 
  two 
  specimens 
  from 
  the 
  Big 
  Horn 
  

   Mountains, 
  the 
  male 
  scandensj 
  the 
  female 
  Junius, 
  are 
  of 
  exceptional 
  

   size, 
  and 
  Arctic 
  American 
  specimens 
  are 
  also 
  distinctly 
  larger 
  than 
  

   those 
  from 
  New 
  England 
  or 
  Nebraska.
