  iinfumigated 
  grain 
  and 
  no 
  naphthalene 
  served 
  as 
  a 
  control. 
  The 
  insects 
  

   found 
  were 
  Rhizopertha 
  dominica, 
  Triboliumferrugineum, 
  and 
  Calandra 
  

   oryzae 
  ; 
  of 
  these 
  T. 
  ferrugineum 
  is 
  harmless, 
  living 
  merely 
  in 
  the 
  

   dust 
  amongst 
  the 
  grain. 
  The 
  results 
  show 
  that 
  storing 
  with 
  naphtha- 
  

   lene 
  it 
  practically 
  as 
  effective 
  as 
  fumigation 
  with 
  carbon 
  bisulphide 
  ; 
  

   that 
  it 
  has 
  no 
  bad 
  effect 
  on 
  the 
  grain 
  from 
  the 
  point 
  of 
  view 
  of 
  its 
  

   suitability 
  as 
  food 
  for 
  cattle 
  and 
  that 
  it 
  does 
  not 
  alter 
  the 
  germina- 
  

   tive 
  capacity 
  to 
  any 
  appreciable 
  extent. 
  It 
  has 
  the 
  following 
  advan- 
  

   tages 
  over 
  fumigation 
  with 
  carbon 
  bisulphide 
  : 
  — 
  It 
  is 
  easy 
  to 
  use, 
  

   and 
  is 
  less 
  dangerous, 
  no 
  special 
  apparatus 
  being 
  necessary 
  ; 
  the 
  cost 
  

   is 
  less 
  and 
  the 
  effect 
  is 
  continuous, 
  whereas 
  carbon 
  bisulphide 
  must 
  

   be 
  allowed 
  to 
  evaporate 
  and 
  any 
  insects 
  which 
  gained 
  access 
  to 
  the 
  

   grain 
  after 
  that 
  would 
  breed 
  unchecked. 
  

  

  In 
  the 
  experiments 
  described, 
  flake 
  naphthalene 
  was 
  used 
  at 
  the 
  rate 
  

   of 
  1 
  lb. 
  per 
  bin, 
  the 
  bin 
  being 
  6 
  ft. 
  high 
  and 
  3 
  ft. 
  in 
  diameter, 
  holding 
  

   between 
  25 
  and 
  30 
  maunds 
  (2,000-2,400 
  lb.) 
  of 
  maize. 
  The 
  naphthalene 
  

   was 
  divided 
  into 
  four 
  parts, 
  each 
  of 
  which 
  was 
  wrapped 
  in 
  a 
  muslin 
  

   bag 
  and 
  suspended 
  at 
  different 
  levels 
  in 
  the 
  bin. 
  It 
  is 
  important 
  that 
  

   the 
  naphthalene 
  should 
  not 
  mix 
  with 
  the 
  grain, 
  and 
  before 
  feeding 
  the 
  

   grain 
  to 
  cattle 
  it 
  should 
  be 
  exposed 
  to 
  the 
  sun 
  for 
  from 
  6 
  to 
  12 
  hours.

  An 
  account 
  is 
  given 
  of 
  the 
  habits 
  and 
  hfe-history 
  of 
  Phylloxera 
  

   vastatrix, 
  with 
  an 
  historical 
  description 
  of 
  its 
  discovery 
  in 
  America 
  

   and 
  its 
  introduction 
  and 
  spread 
  in 
  Europe. 
  In 
  1875 
  it 
  was 
  introduced 
  

   accidentally 
  into 
  Victoria 
  in 
  some 
  vines 
  imported 
  from 
  Europe 
  ; 
  the 
  

   first 
  attacks 
  were 
  noticed 
  near 
  Geelong. 
  Under 
  legislative 
  authority 
  

   whole 
  areas 
  of 
  vines 
  were 
  destroyed 
  to 
  annihilate 
  the 
  pest, 
  but 
  in 
  spite 
  

   of 
  this 
  further 
  attacks 
  occurred 
  in 
  the 
  Bendigo, 
  Goulburn 
  Valley 
  and 
  

   Rutherglen 
  districts, 
  where 
  similar 
  measures 
  were 
  taken, 
  but 
  with 
  as 
  

   little 
  success. 
  These 
  attacks 
  caused 
  a 
  considerable 
  set-back 
  to 
  the 
  

   important 
  industry 
  of 
  viticulture 
  in 
  Victoria 
  ; 
  it 
  is, 
  however, 
  steadily 
  

   recovering, 
  owing 
  to 
  the 
  reconstitution 
  of 
  the 
  vineyards 
  with 
  American 
  

   resistant 
  vines.

  The 
  author 
  figures 
  and 
  briefly 
  describes 
  Fidicina 
  pidlata, 
  Berg, 
  and 
  

   Carineta 
  fasciculata, 
  Ger. 
  These 
  two 
  species 
  occur 
  together 
  in 
  Brazil, 
  

   though 
  the 
  former 
  is 
  more 
  numerous 
  in 
  Caconde 
  and 
  the 
  latter 
  in 
  

   Campinas 
  and 
  Itatinga. 
  They 
  were 
  first 
  noticed 
  by 
  coffee-planters 
  in 
  

   1904 
  in 
  Caconde, 
  and 
  have 
  since 
  been 
  recorded 
  from 
  various 
  widely 
  

   separated 
  localities 
  in 
  the 
  State. 
  On 
  uncultivated 
  land 
  the 
  insects 
  

   feed, 
  in 
  their 
  larval 
  and 
  nymphal 
  stages, 
  upon 
  the 
  roots 
  of 
  indigenous 
  

   trees. 
  When 
  the 
  bush 
  is 
  cleared 
  and 
  coffee 
  planted 
  on 
  the 
  same 
  ground, 
  

   the 
  nymphs 
  speedily 
  adapt 
  themselves 
  to 
  the 
  new 
  conditions 
  and 
  feed 
  

   upon 
  the 
  roots 
  of 
  the 
  coffee 
  trees, 
  doing 
  considerable 
  damage. 
  It 
  is 
  

   recommended 
  that 
  when 
  the 
  presence 
  of 
  cicada 
  nymphs 
  is 
  suspected 
  

   the 
  soil 
  should 
  be 
  turned 
  over 
  round 
  the 
  roots 
  of 
  the 
  coffee.
