  Of

  three

  The 
  author 
  

   gives 
  a 
  full 
  description 
  of 
  the 
  last-named 
  species 
  in 
  all 
  stages. 
  The 
  

   eggs 
  are 
  laid 
  at 
  night 
  in 
  the 
  second 
  half 
  of 
  September 
  and 
  early 
  in 
  

   October. 
  The 
  females 
  seem 
  to 
  prefer 
  dewy 
  nights, 
  when 
  they 
  cUmb 
  

   up 
  the 
  stems 
  of 
  the 
  lucerne, 
  on 
  which 
  they 
  feed, 
  and 
  drop 
  their 
  eggs 
  

   on 
  to 
  the 
  ground. 
  In 
  the 
  laboratory 
  the 
  eggs 
  hatched 
  out 
  in 
  14 
  to 
  24 
  

   days, 
  and 
  the 
  larvae 
  almost 
  immediately 
  disappeared 
  into 
  the 
  soil. 
  The 
  

   adults 
  begin 
  to 
  die 
  in 
  October 
  and 
  none 
  are 
  to 
  be 
  found 
  by 
  November. 
  

   The 
  author 
  could 
  not 
  ascertain 
  if 
  any 
  hibernate. 
  The 
  larvae 
  have 
  

   considerably 
  increased 
  in 
  size 
  by 
  the 
  end 
  of 
  November, 
  and 
  are 
  then 
  

   at 
  a 
  depth 
  of 
  4 
  to 
  6 
  inches, 
  feeding 
  on 
  the 
  tender 
  rootlets 
  of 
  the 
  lucerne. 
  

   The 
  larval 
  stage 
  lasts 
  about 
  6 
  months, 
  till 
  the 
  following 
  May 
  ; 
  the 
  

   pupal 
  stage 
  lasts 
  from 
  10 
  to 
  15 
  days 
  and 
  the 
  imago 
  appears 
  about 
  the 
  

   middle 
  of 
  June. 
  It 
  is 
  then 
  often 
  the 
  prey 
  of 
  an 
  Ascarid, 
  which 
  is 
  at 
  

   present 
  being 
  studied. 
  During 
  July, 
  August, 
  and 
  September 
  the 
  

   immature 
  adults 
  remain 
  hidden 
  by 
  day 
  a 
  couple 
  of 
  inches 
  beneath 
  

   the 
  surface, 
  whence 
  they 
  issue 
  at 
  night 
  to 
  feed. 
  Although 
  the 
  damage 
  

   done 
  by 
  larvae 
  and 
  adults 
  to 
  the 
  lucerne 
  plantations 
  at 
  Portici 
  are 
  by 
  

   no 
  means 
  negligible, 
  yet 
  it 
  is 
  not 
  such 
  as 
  to 
  cause 
  alarm.

  The 
  larva 
  of 
  Sitones 
  humeralis, 
  Steph., 
  feeds 
  on 
  the 
  roots 
  of 
  various

  the 
  slight 
  differences 
  existing 
  between 
  the 
  larva

  for 
  instance, 
  that 
  of 
  Otiorrhynchus

  the

   believes 
  that 
  the 
  distinctive 
  characteristics 
  of 
  the 
  larval 
  stage 
  of 
  the 
  

   various 
  species 
  of 
  Sitones 
  will 
  not 
  be 
  markedly 
  different. 
  A 
  very 
  

   fully 
  detailed 
  description 
  is 
  given 
  of 
  S. 
  humeralis, 
  the 
  full-grown 
  larvae 
  

   of 
  which 
  were 
  found 
  at 
  Portici 
  early 
  in 
  May. 
  About 
  the 
  middle 
  of 
  

   the 
  same 
  month 
  nearly 
  all 
  had 
  transformed 
  into 
  pupae. 
  The 
  pupal 
  

   stage 
  lasts 
  from 
  10 
  to 
  14 
  days. 
  In 
  captivity 
  the 
  imago 
  appeared 
  in 
  

   the 
  first 
  week 
  of 
  June.

  a 
  detailed 
  account 
  of 
  the 
  best 
  methods 
  of 
  packing 
  

   apples

  Regarding 
  the 
  wiping 
  of 
  apples 
  there 
  has 
  been 
  some 
  

   discussion. 
  The 
  advent 
  of 
  the

  has 
  made 
  spraying 
  impera- 
  

   tive 
  and 
  it 
  is 
  this 
  spray 
  that 
  is 
  objectionable.
