  The 
  first 
  part 
  of 
  a 
  catalogue 
  of 
  Australian 
  Coccidae 
  is 
  given, 
  in 
  

   which 
  the 
  species 
  are 
  described, 
  with 
  their 
  mode 
  of 
  occurrence 
  and 
  

   distribution. 
  In 
  the 
  present 
  part, 
  14 
  species 
  of 
  the 
  genus 
  Aspidiotus 
  

   are 
  dealt 
  with, 
  of 
  which 
  three 
  are 
  new, 
  namely 
  A. 
  alatus, 
  occurring 
  

   on 
  the 
  twigs 
  and 
  leaves 
  of 
  Eucalyptus 
  at 
  Dubbo 
  and 
  Wagga, 
  N.S.W. 
  ; 
  

   A.

  the 
  trunk 
  and 
  branches 
  of 
  a 
  white 
  gum 
  (Eucalyptus 
  sp.) 
  

   at 
  Narara 
  ; 
  and 
  A. 
  coralinus, 
  on 
  the 
  young 
  foliage 
  and

  F. 
  W. 
  Urich 
  is 
  reported 
  to 
  have 
  stated 
  (January 
  1914) 
  that 
  he 
  had 
  

   not 
  met 
  with 
  any 
  particularly 
  severe 
  attacks, 
  but 
  on 
  many 
  estates, 
  

   beetles 
  {Stirastoma 
  depressum) 
  and 
  larvae 
  were 
  being 
  caught 
  in 
  large 
  

   numbers 
  and 
  the 
  moment 
  was 
  opportune 
  for 
  spraying 
  trees, 
  especially 
  

   those 
  from 
  three 
  to 
  five 
  years 
  old. 
  The 
  beetles 
  are 
  very 
  active 
  during 
  

   the 
  dry 
  months 
  and 
  spraying 
  should 
  be 
  done 
  immediately. 
  Urich 
  

   recommends 
  that 
  posters 
  be 
  printed 
  calling 
  attention 
  to 
  the 
  beetles 
  

   and 
  the 
  methods 
  of 
  control, 
  which 
  should 
  be 
  put 
  in 
  conspicuous 
  places 
  

   in 
  the 
  badly 
  affected 
  districts. 
  Thrips 
  {Heliothrips 
  suhrocinctus) 
  were 
  

   on 
  the 
  increase. 
  To 
  prevent 
  damage 
  to 
  the 
  June 
  crop, 
  spraying 
  is 
  

   required 
  before 
  the 
  new 
  growth 
  of 
  leaves 
  begins.

  and 
  

   limed 
  in 
  the 
  latter 
  part

  The 
  pink 
  boll 
  worms, 
  Gelechia 
  gossypiella, 
  are 
  now 
  present 
  hterally 
  

   in 
  millions, 
  in 
  the 
  dry 
  cotton 
  bolls 
  stored 
  on 
  the 
  tops 
  of 
  the 
  fellahin 
  

   houses. 
  According 
  to 
  A. 
  Andres, 
  the 
  larvae 
  form 
  cocoons 
  in 
  the 
  

   interior 
  of 
  the 
  seeds 
  and 
  remain 
  in 
  a 
  dormant 
  state 
  for 
  as 
  long 
  as 
  

   seven 
  months, 
  without 
  requiring 
  any 
  nutriment. 
  The 
  storing 
  of 
  

   cotton 
  sticks 
  containing 
  dried 
  and 
  diseased 
  bolls, 
  which 
  afford 
  pro- 
  

   tection 
  to 
  the 
  moth 
  and 
  larva, 
  allows 
  the 
  generation 
  to 
  be 
  carried 
  on 
  

   from 
  one 
  season 
  to 
  another. 
  It 
  might 
  be 
  advisable 
  to 
  introduce 
  

   into 
  the 
  ordinance 
  now 
  under 
  reconstruction, 
  a 
  proviso 
  that 
  all 
  cotton 
  

   sticks 
  be 
  destroyed 
  by 
  fire 
  or 
  carbonized 
  before 
  a 
  fixed 
  date. 
  It 
  is 
  

   obviously 
  of 
  importance 
  to 
  retain 
  as 
  much 
  fuel 
  as 
  possible 
  and 
  the 
  

   carbonization 
  of 
  the 
  wood 
  suggests 
  a 
  compromise 
  of 
  economic 
  value. 
  

   The 
  inconvenience 
  that 
  cultivators 
  will 
  be 
  put 
  to 
  is 
  not 
  a 
  sufficient 
  

   reason 
  for 
  refusing 
  to 
  carry 
  out 
  what 
  will 
  not 
  only 
  be 
  a 
  means 
  of 
  

   destroying 
  and 
  preventing 
  the 
  reproduction 
  of 
  the 
  pink 
  boll 
  worm, 
  

   but 
  also 
  of 
  reducing 
  the 
  numbers 
  of 
  the 
  common 
  boll 
  worm 
  (Earias 
  

   insulana). 
  It 
  is 
  recommended 
  that 
  all 
  cotton 
  sticks 
  be 
  converted 
  

   into 
  charcoal 
  before 
  removal 
  from 
  the 
  fields. 
  A 
  table 
  is

  in 
  7
