  Hyppa 
  xylinoides, 
  commencing 
  the 
  latter 
  part 
  of 
  July, 
  con- 
  

   tinned 
  through 
  all 
  of 
  August 
  and 
  September 
  into 
  the 
  early 
  

   part 
  of 
  October. 
  

  

  Luperina 
  reniformis 
  continued 
  throughout 
  August 
  and 
  

   September, 
  and 
  reappeared 
  in 
  the 
  last 
  half 
  of 
  October. 
  

  

  Leucania 
  unipuncta, 
  after 
  the 
  appearance 
  of 
  a 
  single 
  individ- 
  

   ual 
  on 
  two 
  evenings 
  in 
  July, 
  was 
  present 
  each 
  evening 
  for 
  the 
  

   space 
  of 
  two 
  months. 
  It 
  was 
  one 
  of 
  the 
  most 
  common 
  moths 
  

   at 
  sugar, 
  and 
  was 
  nearly 
  always 
  in 
  remarkably 
  good 
  condition. 
  

  

  AmpMpyra 
  pyramidoides. 
  appearing 
  first 
  on 
  July 
  17th, 
  

   continued, 
  not 
  every 
  evening, 
  however, 
  for 
  more 
  than 
  two 
  and 
  

   a 
  half 
  months. 
  

  

  Orthosia 
  ferrugineoides 
  was 
  constant 
  in 
  its 
  presence, 
  and 
  

   also 
  an 
  abundant 
  species 
  from 
  its 
  first 
  appearance 
  until 
  the 
  

   close 
  of 
  the 
  season. 
  

  

  Orthosia 
  helva 
  was 
  confined 
  to 
  the 
  month 
  of 
  August, 
  but 
  

   was 
  uniformly 
  present 
  after 
  the 
  5th. 
  

  

  Of 
  the 
  Xylinas, 
  laticinerea 
  was 
  the 
  last 
  to 
  appear. 
  It 
  was 
  

   in 
  abundance 
  and 
  in 
  perfect 
  condition 
  at 
  the 
  cessation 
  of 
  su- 
  

   garing. 
  It 
  was 
  the 
  first 
  to 
  appear 
  the 
  ensuing 
  spring 
  (1876), 
  

   on 
  the 
  11th 
  of 
  April, 
  followed 
  a 
  few 
  days 
  thereafter 
  (April 
  25) 
  

   by 
  X. 
  Betliunei. 
  

  

  Erastria 
  carneola 
  had 
  a 
  long 
  duration, 
  and 
  was 
  very 
  seldom 
  

   absent, 
  although 
  never 
  appearing 
  in 
  large 
  numbers. 
  It 
  con- 
  

   tinued 
  until 
  late 
  in 
  September. 
  As 
  it 
  is 
  known 
  to 
  occur 
  in 
  

   the 
  month 
  of 
  May, 
  its 
  four 
  months 
  presence 
  with 
  us 
  is 
  evidence 
  

   of 
  a 
  succession 
  of 
  broods, 
  as 
  is 
  also 
  shown 
  in 
  the 
  freshness 
  of 
  

   examples 
  collected 
  at 
  various 
  times 
  throughout 
  the 
  season. 
  

  

  Catocala 
  parta 
  continued 
  for 
  a 
  very 
  long 
  time, 
  having 
  been 
  

   taken 
  on 
  fifteen 
  evenings 
  in 
  the 
  months 
  of 
  July, 
  August 
  and 
  

   September. 
  

  

  C. 
  ultronia 
  was 
  the 
  most 
  abundant 
  of 
  the 
  Catocalas, 
  and, 
  

   although 
  not 
  soen 
  in 
  the 
  month 
  of 
  September, 
  was 
  observed 
  

   on 
  eighteen 
  evenings 
  during 
  the 
  preceding 
  two 
  months. 
  

  

  Homopyralis 
  tactus 
  was 
  a 
  remarkably 
  constant 
  visitor, 
  hav- 
  

   ing 
  been 
  unobserved 
  on 
  one 
  evening 
  only 
  for 
  nearly 
  two 
  

   months. 
  

  

  Pseudothyatira 
  expulirix 
  was 
  present 
  each 
  evening 
  of 
  the 
  

   month 
  commencing 
  July 
  15th. 
  

  

  The 
  following 
  table 
  shows 
  the 
  period 
  of 
  duration 
  of 
  several 
  

   of 
  the 
  species 
  and 
  their 
  comparative 
  constancy 
  of 
  attendance 
  

   at 
  sugar.
