  Thea 
  22-punctata 
  is 
  an 
  abundant 
  ladybird 
  in 
  all 
  parts 
  of 
  Sicily. 
  In 
  

   June 
  it 
  completes 
  its 
  cycle 
  in 
  19-21 
  days, 
  while 
  in 
  August 
  this 
  takes 
  

   24-28 
  days. 
  According 
  to 
  these 
  figures 
  seven 
  generations 
  may 
  occur 
  

   from 
  May 
  to 
  October. 
  The 
  author 
  finds 
  that 
  neither 
  the 
  adult 
  nor 
  

   the 
  larva 
  feeds 
  on 
  aphids, 
  and 
  if 
  aphid-infested 
  leaves 
  or 
  twigs 
  are 
  

   fed 
  to 
  them 
  they 
  die 
  of 
  starvation. 
  They 
  feed 
  on 
  the 
  conidia 
  and 
  

   spores 
  of 
  various 
  species 
  of 
  Oidium 
  found 
  on 
  the 
  pumpkin, 
  Plantago 
  sp.. 
  

   Beta 
  vulgaris, 
  various 
  Brassicaceae, 
  the 
  oak, 
  the 
  hawthorn. 
  Clematis 
  

   vitalba, 
  Euonymus 
  sp., 
  and 
  the 
  vine. 
  The 
  adult 
  is 
  also 
  able 
  to 
  use 
  

   the 
  sugary 
  substances 
  excreted 
  by 
  the 
  leaves 
  of 
  some 
  plants 
  and 
  the 
  

   larva 
  sometimes 
  sucks 
  the 
  eggs 
  of 
  Thea 
  itself. 
  The 
  author 
  thus 
  

   establishes 
  the 
  fact 
  that 
  Thea 
  22-punctata 
  is 
  normally 
  mycophagous.

  Coconut 
  cultivation 
  on 
  the 
  island 
  of 
  Viti 
  Levu 
  was 
  practically 
  given 
  

   up 
  many 
  years 
  ago, 
  owing 
  to 
  the 
  serious 
  injury 
  done 
  to 
  the 
  leaves 
  by 
  

   a 
  small 
  moth, 
  Levuana 
  iridescens, 
  B.B., 
  not 
  hitherto 
  found 
  elsewhere. 
  

   Since 
  the 
  end 
  of 
  1912 
  a 
  change 
  has 
  taken 
  place 
  in 
  the 
  appearance 
  of 
  

   the 
  coconuts 
  in 
  most 
  parts 
  of 
  the 
  island 
  and 
  the 
  author 
  thinks 
  the 
  

   chance 
  of 
  combating 
  the 
  pest 
  successfully 
  has 
  now 
  considerably 
  

   increased. 
  No 
  control 
  measures 
  are

  This 
  insect 
  is 
  widely 
  distributed 
  in 
  Ceylon 
  as 
  a 
  pest 
  of 
  tea. 
  Its 
  

   presence 
  is 
  indicated 
  by 
  the 
  withering 
  of 
  the 
  leaves 
  and 
  by 
  castings 
  

   ejected 
  by 
  the 
  caterpillar 
  from 
  its 
  burrow. 
  These 
  castings 
  are 
  oval- 
  

   cylindrical 
  in 
  shape 
  and 
  yellowish 
  or 
  crimson 
  in 
  colour. 
  If 
  one 
  of 
  the 
  

   attacked 
  branches 
  is 
  cut 
  open, 
  a 
  tunnel, 
  widening 
  out 
  at 
  irregular 
  

   intervals, 
  will 
  be 
  found 
  running 
  along 
  its 
  centre. 
  These 
  wider 
  portions 
  

   are 
  of 
  the 
  nature 
  of 
  lateral 
  galleries 
  that 
  may 
  reach 
  almost 
  to 
  the 
  out- 
  

   side. 
  The 
  width 
  of 
  the 
  tunnel 
  depends 
  on 
  the 
  age 
  of 
  the 
  caterpillar, 
  

   and 
  the 
  galleries 
  of 
  the 
  young 
  larvae 
  are 
  usually 
  straight. 
  The 
  

   galleries 
  may 
  be 
  so 
  extensive 
  as 
  to 
  girdle 
  the 
  stem 
  ; 
  they 
  may 
  also 
  go 
  

   down 
  into 
  the 
  roots. 
  When 
  full-grown 
  the 
  larva 
  cuts 
  a 
  circular 
  trap- 
  

   door 
  for 
  the 
  exit 
  of 
  the 
  moth. 
  A 
  variety 
  of 
  insects 
  has 
  been 
  found 
  in 
  

   the 
  tunnels 
  and 
  in 
  some 
  cases 
  they 
  have 
  been 
  mistaken 
  for 
  the 
  real 
  

   culprit. 
  

  

  The 
  Zeuzera 
  has 
  been 
  found 
  feeding 
  on 
  the 
  following 
  plants 
  in
