  had 
  been 
  laid 
  some 
  time 
  during 
  the 
  interval 
  between 
  5 
  p. 
  m. 
  on 
  

   June 
  23 
  and 
  8 
  a. 
  m. 
  on 
  June 
  24. 
  The 
  female 
  was 
  dead 
  on 
  June 
  25 
  

   (8 
  a. 
  m.). 
  The 
  female 
  lived 
  for 
  about 
  four 
  days 
  and 
  the 
  male 
  only 
  

   about 
  two 
  days. 
  Eggs 
  were 
  deposited 
  in 
  two 
  and 
  one-half 
  days. 
  

  

  On 
  July 
  1 
  (8 
  a. 
  m.) 
  a 
  male 
  moth 
  and 
  a 
  female 
  moth 
  just 
  emerged 
  

   were 
  placed 
  in 
  a 
  jar 
  with 
  an 
  apple 
  twig. 
  Food 
  was 
  furnished 
  the 
  

   pair 
  of 
  moths 
  by 
  supplying 
  them 
  with 
  a 
  piece 
  of 
  absorbent 
  cotton 
  

   which 
  had 
  been 
  saturated 
  in 
  a 
  weak 
  solution 
  of 
  sirup. 
  The 
  cage 
  

   was 
  examined 
  the 
  next 
  day 
  at 
  9 
  o'clock 
  and 
  both 
  moths 
  were 
  quite 
  

   restless. 
  On 
  July 
  3 
  at 
  8 
  a. 
  m. 
  an 
  egg 
  mass 
  was 
  found 
  on 
  the 
  twig 
  

   and 
  both 
  moths 
  were 
  still 
  active. 
  The 
  male 
  had 
  died 
  by 
  9 
  a. 
  m. 
  on 
  

   July 
  4 
  and 
  the 
  female 
  by 
  8 
  a. 
  m. 
  on 
  July 
  5. 
  Copulation 
  was 
  not 
  

   observed. 
  In 
  this 
  case 
  the 
  male 
  lived 
  about 
  three 
  days 
  and 
  the 
  

   female 
  about 
  four 
  days. 
  The 
  eggs 
  were 
  laid 
  inside 
  of 
  two 
  days 
  after 
  

   emergence 
  of 
  the 
  moths. 
  

  

  On 
  July 
  16 
  two 
  moths 
  were- 
  observed 
  mating 
  and 
  at 
  noon 
  were 
  put 
  

   in 
  breeding 
  jar. 
  The 
  cage 
  was 
  again 
  examined 
  on 
  July 
  17 
  and 
  the 
  

   moths 
  had 
  ceased 
  copulating 
  and 
  were 
  crawling 
  over 
  the 
  sides 
  of 
  the 
  

   jar. 
  On 
  July 
  18 
  at 
  4 
  p. 
  m. 
  the 
  cage 
  was 
  again 
  looked 
  over 
  and 
  an 
  

   egg 
  mass 
  was 
  found 
  deposited 
  on 
  the 
  twig. 
  The 
  life 
  of 
  the 
  moths 
  

   could 
  not 
  be 
  determined, 
  as 
  the 
  time 
  of 
  emergence 
  was 
  not 
  known. 
  

   A 
  period 
  of 
  about 
  two 
  days 
  is 
  shown 
  between 
  the 
  time 
  of 
  copulation 
  

   and 
  the 
  time 
  of 
  deposition 
  of 
  the 
  egg 
  mass. 
  

  

  There 
  are 
  not 
  sufficient 
  data 
  bearing 
  on 
  the 
  length 
  of 
  life 
  of 
  the 
  

   adults 
  to 
  justify 
  any 
  generalization. 
  The 
  writer 
  believes 
  there 
  is 
  

   a 
  wide 
  variation 
  in 
  the 
  longevity 
  of 
  the 
  moths 
  and 
  that 
  the 
  females 
  

   usually 
  outlive 
  the 
  males. 
  It 
  is 
  also 
  reasonable 
  to 
  expect 
  the 
  moths 
  

   to 
  live 
  for 
  a 
  longer 
  period 
  under 
  natural 
  conditions 
  than 
  is 
  the 
  case 
  

   when 
  they 
  are 
  kept 
  in 
  confinement. 
  It 
  is 
  also 
  likely 
  that 
  the 
  females 
  

   do 
  not 
  oviposit 
  out 
  of 
  doors 
  as 
  readily 
  as 
  when 
  confined 
  in 
  rearing 
  

   jars 
  with 
  the 
  males. 
  

  

  Observations 
  under 
  insectary 
  conditions 
  go 
  to 
  prove 
  that 
  the 
  

   female 
  if 
  left 
  unmolested 
  during 
  oviposition 
  deposits 
  all 
  her 
  eggs 
  

   in 
  a 
  single 
  mass. 
  All 
  egg 
  masses 
  deposited 
  in 
  rearing 
  cages 
  consisted 
  

   of 
  more 
  than 
  100 
  eggs, 
  the 
  greatest 
  number 
  from 
  one 
  female 
  being 
  

   140. 
  In 
  the 
  orchard 
  it 
  is 
  not 
  difficult 
  to 
  find 
  rather 
  small 
  egg 
  masses. 
  

   The 
  smallest 
  one 
  observed 
  was 
  composed 
  of 
  25 
  eggs. 
  In 
  making 
  

   field 
  observations 
  the 
  writer 
  noticed 
  that 
  the 
  female 
  when 
  oviposit- 
  

   ing 
  would 
  cease 
  the 
  operation 
  very 
  readily 
  if 
  disturbed 
  in 
  any 
  way 
  

   and 
  fly 
  or 
  crawl 
  away. 
  Ovipositing 
  females 
  were 
  observed 
  changing 
  

   position 
  when 
  insects 
  such 
  as 
  ants, 
  ground 
  beetles, 
  and 
  ladybird 
  

   larvae 
  or 
  adults 
  came 
  too 
  near 
  them. 
  One 
  species 
  of 
  Coccinellidae 
  

   that 
  is 
  especially 
  prcdaceous 
  on 
  the 
  green 
  aphis 
  of 
  the 
  apple 
  was 
  

   noticed 
  several 
  times 
  disturbing 
  females 
  in 
  the 
  act 
  of 
  oviposition, 
  

   compelling 
  them 
  to 
  crawl 
  or 
  fly 
  to 
  another 
  place 
  to 
  deposit 
  the
