  to 
  be 
  more 
  usual 
  for 
  the 
  American 
  specimens 
  to 
  have 
  them 
  

   broader 
  and 
  shorter 
  than 
  the 
  European. 
  

  

  " 
  Only 
  to 
  the 
  first-named 
  modification 
  in 
  the 
  mixture 
  of 
  

   gray 
  and 
  brown 
  colors, 
  might 
  some 
  importance 
  be 
  attached, 
  

   since 
  it 
  seems 
  to 
  pertain, 
  although 
  not 
  without 
  exception, 
  

   to 
  the 
  majority 
  of 
  compared 
  species, 
  and 
  may 
  therefore 
  be 
  

   referred 
  to 
  a 
  common 
  cause, 
  arising 
  from 
  the 
  different 
  climates 
  

   of 
  continental 
  eastern 
  North 
  America 
  and 
  insular 
  western 
  

   Europe. 
  Which 
  of 
  the 
  many 
  climatic 
  factors 
  influences 
  this 
  

   modification 
  of 
  color 
  — 
  whether 
  it 
  is 
  due 
  to 
  the 
  more 
  intense 
  

   heat 
  and 
  dryness, 
  or 
  to 
  the 
  severe 
  winter 
  of 
  the 
  transatlantic 
  

   faunal 
  territory, 
  or 
  to 
  both 
  combined 
  and 
  as 
  opposed 
  to 
  the 
  

   cooler 
  and 
  damper 
  summers 
  and 
  milder 
  winters 
  of 
  the 
  cis- 
  

   atlantic 
  — 
  cannot 
  now 
  be 
  determined. 
  It 
  is 
  well 
  known 
  that 
  

   the 
  coloration 
  becomes 
  generally 
  darker 
  and 
  blacker 
  as 
  we 
  

   approach 
  the 
  pole 
  or 
  ascend 
  in 
  elevation 
  ; 
  but 
  it 
  is 
  doubtful 
  

   if 
  the 
  greater 
  cold 
  of 
  the 
  winter 
  is 
  the 
  real 
  cause 
  of 
  this 
  effect.'

  C. 
  fidicularia 
  appears 
  to 
  be 
  a 
  rare 
  species 
  with 
  us. 
  Mr. 
  

   von 
  Meske 
  has 
  taken 
  it, 
  at 
  sugar, 
  at 
  Sharon 
  Springs, 
  N. 
  Y., 
  

   on 
  August 
  15th, 
  in 
  two 
  examples. 
  Mr. 
  W. 
  W. 
  Hill 
  has 
  cap- 
  

   tured 
  it 
  in 
  Lewis 
  county, 
  1ST. 
  Y., 
  on 
  August 
  1st, 
  also 
  at 
  sugar. 
  

   I 
  have 
  taken 
  it 
  on 
  but 
  one 
  occasion, 
  at 
  Schoharie, 
  N. 
  Y., 
  on 
  

   5th 
  of 
  September. 
  It 
  has 
  not 
  made 
  its 
  appearance, 
  at 
  sugar, 
  

   during 
  my 
  two 
  years' 
  collecting 
  by 
  that 
  method 
  at 
  Schenec- 
  

   tady. 
  Mr. 
  Morrison's 
  example 
  was 
  from 
  the 
  Adirondack 
  

   region. 
  A 
  species, 
  believed 
  to 
  be 
  the 
  same,- 
  and 
  referred 
  to 
  

   C. 
  multifera 
  Walker, 
  in 
  Vol. 
  I, 
  of 
  the 
  Canadian 
  Entomologist 
  

   (page 
  84) 
  was 
  captured 
  at 
  Coburg, 
  Ontario. 
  Mr. 
  Walker's 
  

   specimen 
  was 
  from 
  Nova 
  Scotia. 
  

  

  C. 
  cubicularis 
  is 
  stated 
  by 
  Gfuenee 
  to 
  be 
  very 
  common 
  in 
  

   the 
  months 
  of 
  June 
  and 
  September. 
  Wood 
  {Index 
  Entomolo- 
  

   gtcus, 
  p. 
  44) 
  refers 
  to 
  it 
  as 
  common 
  in 
  gardens 
  and 
  meadows 
  

   during 
  the 
  middle 
  of 
  June. 
  Dr. 
  Speyer 
  in 
  his 
  Fauna 
  of 
  

   Waldeck, 
  represents 
  it 
  as 
  common 
  throughout 
  the 
  month 
  of 
  

   May, 
  and 
  with 
  a 
  second 
  generation, 
  less 
  abundant, 
  extending 
  

   from. 
  the 
  latter 
  part 
  of 
  June 
  to 
  the 
  last 
  of 
  August. 
  

  

  A 
  delay 
  in 
  the 
  printing 
  of 
  these 
  papers 
  enables 
  me 
  to 
  add 
  

   to 
  the 
  manuscript 
  as 
  above 
  prepared, 
  a 
  comparison 
  made 
  by 
  

   Dr. 
  Speyer, 
  at 
  my 
  request, 
  of 
  C. 
  fidicularia 
  with 
  the 
  Euro- 
  

   pean 
  species.
