  The 
  author 
  says 
  that, 
  with 
  the 
  exception 
  of 
  Phylloxera 
  and 
  

   Hemileia 
  vastatrix, 
  there 
  are 
  no 
  enemies 
  or 
  diseases 
  of 
  cultivated 
  plants 
  

   in 
  the 
  Far 
  East 
  which 
  threaten 
  complete 
  destruction 
  of 
  any 
  particular 
  

   crop, 
  but 
  that, 
  nevertheless, 
  nearly 
  every 
  form 
  of 
  cultivation 
  is 
  subject 
  

   to 
  the 
  attack 
  of 
  some 
  parasite. 
  Up 
  to 
  the 
  present 
  the 
  principal 
  work 
  

   on 
  this 
  subject 
  in 
  the 
  Far 
  East 
  has 
  been 
  done 
  by 
  the 
  Botanical 
  Garden 
  

   at 
  Buitenzorg, 
  the 
  Agricultural 
  Research 
  Institute 
  at 
  Pusa 
  and 
  the 
  

   Bureau 
  of 
  Science 
  at 
  Manila. 
  

  

  Twenty-two 
  pages 
  of 
  the 
  work 
  are 
  devoted 
  to 
  a 
  detailed 
  statement 
  

   of 
  the 
  fungus 
  parasites 
  of 
  the 
  various 
  cultivated 
  plants 
  of 
  Tongking. 
  

   A 
  chapter 
  is 
  contributed 
  by 
  the 
  Abbe 
  J. 
  de 
  Joannis 
  as 
  to 
  the 
  best 
  means 
  

   of 
  capturing 
  and 
  despatching 
  insect 
  specimens, 
  followed 
  by 
  a 
  list, 
  

   covering 
  eleven 
  pages, 
  of 
  271 
  species 
  of 
  Lepidoptera 
  known 
  to 
  be 
  

   injurious 
  to 
  vegetation 
  in 
  the 
  Far 
  East, 
  with 
  the 
  plants 
  they 
  attack. 
  

  

  The 
  author 
  then 
  gives 
  a 
  list 
  of 
  the 
  principal 
  agricultural 
  pests 
  in 
  

   the 
  Far 
  East, 
  compiled 
  from 
  the 
  literature 
  on 
  the 
  subject. 
  Only 
  

   those 
  pests 
  of 
  the 
  more 
  important 
  crops 
  reported 
  from 
  Tongking 
  

   are 
  here 
  dealt 
  with. 
  

  

  Rice 
  is 
  attacked 
  by 
  the 
  following 
  : 
  — 
  Schoenobius 
  bipimctifer, 
  Wlk., 
  and 
  

   Sesamia 
  inferens, 
  Wlk., 
  the 
  larvae 
  of 
  which 
  bore 
  into 
  the 
  stems 
  of 
  rice, 
  

   sugar-cane, 
  millet, 
  maize, 
  etc., 
  and 
  against 
  which 
  flooding 
  of 
  the 
  rice- 
  

   fields 
  is 
  recommended. 
  Cnapholocrocis 
  niedinalis, 
  Gn., 
  is 
  a 
  minute 
  

   species, 
  the 
  larvae 
  of 
  which 
  bore 
  into 
  the 
  stems. 
  All 
  rice 
  stems 
  

   which 
  show 
  signs 
  of 
  attack 
  should 
  be 
  pulled 
  up 
  and 
  burnt. 
  The 
  

   leaves 
  are 
  attacked 
  by 
  the 
  caterpillars 
  of 
  several 
  Lepidoptera, 
  

   including 
  Mycalesis 
  minens, 
  L., 
  Precis 
  [Junonia) 
  almana, 
  L., 
  Parnara 
  

   mathias, 
  F., 
  Padraona 
  dara, 
  KolL, 
  Telicota 
  augias, 
  L., 
  Diacrisia 
  

   ohliqua, 
  Wlk., 
  Amsacta 
  lactinea, 
  Cr., 
  Chloridea 
  obsoleta, 
  F., 
  Cirphis 
  

   loreyi, 
  Dup. 
  (which 
  is 
  one 
  of 
  the 
  most 
  dangerous 
  species), 
  Cirphis 
  

   unipuncta, 
  Haw. 
  (also 
  a 
  formidable 
  pest), 
  Prodenia 
  litura, 
  F., 
  Spodoptera 
  

   mauritia, 
  Bd. 
  (against 
  which 
  trap-trenches 
  should 
  be 
  dug), 
  Mods 
  

   (Chalciope) 
  frugalis, 
  F., 
  Grammodes 
  (Chalciope) 
  geometrica, 
  F., 
  

   Dasychira 
  securis, 
  Hb., 
  Dinara 
  (Antycira) 
  combiista, 
  Wlk., 
  Artona 
  

   walkeri, 
  Moore, 
  Doloessa 
  viridis, 
  L., 
  Ancylolomia 
  chrysographella, 
  

   Koll., 
  Pyralis 
  pictalis, 
  Curt., 
  Nymphula 
  jiuctuosalis 
  y 
  Z. 
  Other 
  pests 
  

   include 
  : 
  — 
  Hispa 
  aenescens, 
  Baly, 
  and 
  Tetroda 
  histeroides, 
  F. 
  (an 
  

   Hemipteron 
  which 
  feeds 
  on 
  the 
  grains). 
  Leptocorisa 
  varicornis, 
  F., 
  

   does 
  considerable 
  damage 
  ; 
  when 
  very 
  numerous 
  on 
  rice, 
  dragging 
  a 
  

   net, 
  of 
  rather 
  large 
  mesh, 
  which 
  is 
  kept 
  stretched 
  over 
  the 
  heads 
  of 
  

   rice, 
  will 
  catch 
  a 
  large 
  number 
  of 
  them. 
  Although 
  their 
  nauseous 
  

   smell 
  protects 
  them 
  from 
  the 
  attacks 
  of 
  birds, 
  they 
  are 
  preyed 
  upon 
  

   by 
  Cicindela 
  sexpunctata, 
  L. 
  Leptocorisa 
  acuta, 
  Thunb., 
  does 
  similar 
  

   damage 
  to 
  the 
  last-named. 
  

  

  Maize 
  is 
  attacked 
  by 
  many 
  of 
  the 
  above-mentioned 
  Lepidopterous 
  

   rice-pests 
  and 
  also 
  by 
  Chilo 
  simplex, 
  Butl., 
  Parnara 
  conjuncta, 
  H. 
  S., 
  

   Diacrisia 
  strigatula,
