  Hort.

  Committee, 
  Mr. 
  A. 
  J. 
  Bliss 
  writes 
  stating 
  that, 
  

   although 
  more 
  knowledge 
  is 
  wanted, 
  evidence 
  is 
  strongly 
  in 
  favour 
  of 
  

   E. 
  lunulattis 
  being 
  merely 
  a 
  scavenger, 
  feeding 
  on 
  the 
  excreta 
  of 
  

   Merodon 
  grubs 
  which 
  inhabit 
  the 
  bulbs, 
  or 
  on 
  decayed 
  bulbs 
  which 
  

   have 
  been 
  attacked 
  by 
  fungoid 
  diseases 
  ; 
  the 
  facts 
  that 
  the 
  larva 
  can 
  

   live 
  on 
  a 
  variety 
  of 
  plants 
  (rhizomes 
  of 
  iris, 
  etc.), 
  has 
  no 
  special 
  food- 
  

   plant, 
  and 
  has 
  only 
  done 
  harm 
  when 
  Merodon 
  or 
  fungi 
  have 
  previously 
  

   attacked 
  the 
  bulb, 
  support 
  the 
  author's 
  arguments. 
  Mr. 
  C. 
  E. 
  Shea, 
  

   however, 
  beheves 
  that 
  the 
  larvae 
  are 
  not 
  hatched 
  on 
  the 
  bulbs 
  and 
  

   he 
  does 
  not 
  think 
  that 
  the 
  larva 
  is 
  only 
  a 
  scavenger, 
  since 
  his 
  own 
  

   experience 
  does 
  not 
  clearly 
  demonstrate 
  the 
  relationship 
  with 
  Merodon 
  

   or 
  fungoid 
  diseases.

  The 
  author 
  suggests 
  the 
  following 
  remedies 
  against 
  ants 
  : 
  — 
  Spraying 
  

   over 
  ant-hills 
  and 
  spots 
  attacked 
  by 
  ants 
  with 
  powdered 
  caustic 
  hme 
  

   gives 
  good 
  results 
  ; 
  if 
  scattered 
  round 
  the 
  trunks 
  of 
  trees 
  it 
  will 
  prevent 
  

   the 
  ants 
  from 
  passing 
  on 
  to 
  them, 
  but 
  the 
  lime 
  must 
  be 
  renewed 
  from 
  

   time 
  to 
  time. 
  A 
  lump 
  of 
  caustic 
  lime 
  placed 
  inside 
  an 
  ant-hill 
  will 
  

   soon 
  exterminate 
  the 
  insects 
  if 
  plenty 
  of 
  water 
  is 
  poured 
  over 
  the 
  spot. 
  

   Ant-hills 
  may 
  be 
  treated 
  with 
  one-half 
  to 
  one 
  pint 
  of 
  tar 
  or 
  kerosene 
  in 
  

   3 
  gallons 
  of 
  boihng 
  water. 
  A 
  solution 
  of 
  f 
  lb. 
  of 
  hyposulphite 
  of 
  soda 
  

   in 
  5 
  pints 
  of 
  warm 
  water 
  is 
  also 
  useful 
  and 
  is 
  harmless 
  to 
  the 
  roots 
  of 
  

   trees, 
  though 
  on 
  beds 
  of 
  plants 
  a 
  weaker 
  solution 
  must 
  be 
  appHed 
  and 
  

   repeated 
  in 
  1-2 
  weeks. 
  In 
  order 
  to 
  prevent 
  ants 
  getting 
  on 
  to 
  trees, 
  

   belts 
  of 
  cotton 
  wool 
  moistened

  20

  carbohc

  may

   used.

  A 
  general 
  account 
  is 
  given 
  of 
  the 
  usefulness 
  of 
  certain 
  insects, 
  them- 
  

   selves 
  phytophagous, 
  in 
  combating 
  pests 
  of 
  cultivated 
  plants. 
  They 
  

   may 
  be 
  useful 
  in 
  acting 
  as 
  hosts 
  for 
  entomophagous 
  species 
  which 
  prey 
  

   upon 
  the 
  pest, 
  such 
  as 
  Siphonophora 
  leptadeniae, 
  which 
  harbours 
  the 
  

   parasites 
  of 
  Aphis 
  sorghi, 
  and 
  Barathra 
  (Mamestra) 
  brassicae, 
  which 
  

   acts 
  as 
  a 
  host 
  for 
  the 
  parasite 
  Trichograrmna 
  semblidis 
  of 
  the 
  vine 
  pest 
  

   Polychrosis 
  botrana. 
  Another 
  example 
  given 
  is 
  Alaba^na 
  argillacea, 
  

   a 
  casual 
  pest 
  on 
  cotton,, 
  but 
  which 
  is 
  nevertheless 
  useful, 
  provided 
  it 
  

   appears 
  late, 
  in 
  suppressing 
  indirectly 
  the 
  far 
  more 
  dreaded 
  annual 
  

   pest 
  Anthonomus 
  grandis 
  by 
  robbing 
  it 
  of 
  its 
  food 
  supply.
