  For 
  some 
  years 
  orchardists 
  in 
  the 
  neighbourhood 
  of 
  Sydney 
  have 
  

   been 
  troubled 
  with 
  an 
  undetermined 
  pest 
  of 
  peach-trees 
  ; 
  early 
  in 
  

   the 
  season 
  a 
  minute 
  larva 
  burrows 
  into 
  the 
  tips 
  of 
  the 
  shoots, 
  eating 
  

   its 
  way 
  downw^ard 
  and 
  causing 
  the 
  terminal 
  leaves 
  to 
  die 
  and 
  the 
  

   injured 
  tw4g 
  to 
  exude 
  gum 
  ; 
  sometimes 
  nearly 
  every 
  shoot 
  is 
  attacked 
  

   in 
  this 
  way. 
  Later 
  on 
  in 
  the 
  season 
  a 
  large 
  percentage 
  of 
  the 
  fruit 
  

   is 
  marked 
  with 
  blotches, 
  covered 
  wath 
  exuding 
  gum, 
  under 
  w^hich 
  the 
  

   skin 
  is 
  gnawed 
  through. 
  A 
  few 
  specimens 
  obtained 
  proved 
  to 
  be 
  

   the 
  larvae 
  of 
  a 
  Tortricid 
  moth, 
  not 
  unlike 
  the 
  w^ell-known 
  codling 
  

   moth. 
  This 
  pest 
  has 
  also 
  been 
  found 
  to 
  attack 
  several 
  other 
  fruits 
  

   such 
  as 
  quinces 
  and 
  apples. 
  The 
  eggs 
  are 
  laid 
  on 
  the 
  tips 
  of 
  the 
  peach 
  

   shoots. 
  Adult 
  caterpillars 
  and 
  the 
  pupae 
  were 
  captured 
  under 
  

   bandages 
  wound 
  round 
  the 
  trees. 
  Spraying 
  of 
  all 
  peach 
  trees 
  in 
  the 
  

   early 
  summer, 
  as 
  soon 
  as 
  the 
  first 
  sign 
  of 
  damage 
  is 
  noticed, 
  with 
  

   .arsenate 
  of 
  lead 
  should 
  prove 
  effective.

  Numerous 
  specimens 
  of 
  the 
  leaf-case 
  moth 
  (Hyalarcta 
  hubneri, 
  

   Westw.) 
  have 
  been 
  received 
  from 
  correspondents 
  who 
  state 
  that 
  it 
  

   has 
  caused 
  considerable 
  damage 
  to 
  apples, 
  quinces, 
  grapes, 
  etc. 
  The 
  

   larva 
  usually 
  bites 
  a 
  piece 
  out 
  of 
  one 
  fruit 
  and 
  then 
  passes 
  on 
  to 
  

   another, 
  until 
  much 
  of 
  the 
  fruit 
  is 
  damaged 
  and 
  useless. 
  They 
  also 
  

   attack 
  the 
  leaves 
  and 
  young 
  buds. 
  Native 
  plants, 
  such 
  as 
  the 
  tea- 
  

   tree 
  {Leptospermum), 
  Eucalyptus, 
  and 
  introduced 
  plants, 
  such 
  as 
  pines 
  

   and 
  Cupressu^', 
  are 
  also 
  attacked. 
  A 
  closely 
  allied 
  species, 
  the 
  ribbed 
  

   €ase 
  or 
  bag 
  moth 
  {H. 
  nigrescens), 
  is 
  destructive 
  to 
  Eu/xilyptus, 
  but 
  

   has 
  not 
  yet 
  damaged 
  fruit 
  trees. 
  This 
  pest 
  is 
  easily 
  controlled 
  with 
  

   arsenate 
  of 
  lead.

  The 
  author 
  referring 
  to 
  Professor 
  Werner's 
  paper 
  [see 
  this 
  Review^ 
  

   Ser. 
  A. 
  i, 
  p. 
  548] 
  notes 
  that 
  similar 
  swarms, 
  sometimes 
  on 
  a 
  very 
  large 
  

   scale, 
  of 
  Coccinellids, 
  especially 
  of 
  C. 
  septempunctaia, 
  have 
  been 
  noted. 
  

   In 
  1877, 
  he 
  observed 
  a 
  swarm 
  on 
  Monte 
  Asinara 
  at 
  3,000 
  feet 
  

   above 
  sea-level, 
  and 
  cites 
  a 
  number 
  of 
  observations 
  to 
  the 
  same 
  effect 
  

   at 
  even 
  greater 
  elevations 
  in 
  the 
  Appenines. 
  In 
  order 
  to 
  ascertain 
  

   whether 
  this 
  phenomenon 
  recurs 
  regularly 
  in 
  places 
  in 
  which 
  it 
  has 
  

   once 
  been 
  observed, 
  the 
  author 
  made 
  several 
  journeys 
  into 
  the 
  moun- 
  

   tains, 
  but 
  has 
  not 
  been 
  able 
  to 
  confirm 
  previous 
  observations. 
  He 
  

   iound 
  that 
  C. 
  septempunctata 
  and 
  allied 
  species 
  swarm 
  on 
  mountain 
  

   tops, 
  either 
  in 
  stony 
  places 
  devoid 
  of 
  vegetation, 
  where 
  the 
  insects 
  

   are 
  found 
  under 
  stones 
  or 
  upon 
  them, 
  or 
  on 
  certain 
  species 
  of 
  plants. 
  

   The 
  time 
  of 
  year 
  when 
  C. 
  septempunctata 
  exhibits 
  a 
  tendency 
  to 
  

   swarm 
  seems 
  to 
  be 
  very 
  variable 
  ; 
  in 
  the 
  case 
  of 
  one 
  mountain 
  top
