  This 
  method 
  of 
  treatment 
  is 
  reported 
  to 
  be 
  gaining 
  ground 
  rapidly 
  in 
  

   Bohemia, 
  in 
  spite 
  of 
  the 
  relatively 
  high 
  cost 
  of 
  the 
  spray 
  material 
  ; 
  

   experiments 
  are 
  in 
  progress 
  with 
  Demilysol 
  and 
  other 
  insecticides 
  in 
  

   the 
  hope 
  of 
  finding 
  something 
  cheaper 
  and 
  at 
  the 
  same 
  time 
  as 
  effective 
  

   as 
  the 
  tobacco 
  spray. 
  

  

  Hylemijia 
  coarctata, 
  Fall., 
  is 
  now 
  to 
  be 
  definitely 
  regarded 
  as 
  a 
  pest 
  

   of 
  cereals 
  in 
  Austria, 
  and 
  fears 
  as 
  to 
  its 
  spread 
  are 
  expressed, 
  for 
  it 
  is 
  

   more 
  or 
  less 
  clear 
  that 
  the 
  insect 
  has 
  been 
  present 
  unrecognised 
  in 
  

   Austria 
  for 
  some 
  time, 
  and 
  the 
  damage 
  done 
  has 
  been 
  attributed 
  to 
  

   Oscinis 
  frit. 
  From 
  Bohemia, 
  complaints 
  have 
  been 
  received 
  of 
  a 
  new 
  

   pest 
  of 
  cereals. 
  Trachea 
  (Hadena) 
  basilinea, 
  F. 
  In 
  Dalmatia, 
  Stauro- 
  

   notiis 
  (Dociostaurus) 
  maroccanus, 
  Thbg., 
  has 
  appeared 
  in 
  increasing 
  

   numbers. 
  Large 
  quantities 
  of 
  Rhynchites 
  pauxillus, 
  Germ., 
  have 
  been 
  

   taken 
  on 
  apple 
  trees 
  near 
  Krems, 
  and 
  Cheimatobia 
  brumata, 
  L., 
  was 
  

   reported 
  from 
  many 
  districts 
  in 
  the 
  spring 
  of 
  last 
  year. 
  The 
  

   Lasiocampid 
  moth, 
  Dendrolimus 
  pini, 
  L., 
  appeared 
  again 
  in 
  the 
  

   neighbourhood 
  of 
  Wiener-Neustadt, 
  and 
  in 
  Bohemia, 
  Panolis 
  flammea, 
  

   Schiff., 
  (griseovariegata, 
  Goeze) 
  frequently 
  in 
  company 
  with 
  Bwpalus 
  

   jyiniarms, 
  L., 
  has 
  done 
  a 
  good 
  deal 
  of 
  damage. 
  The 
  larvae 
  of 
  the 
  

   former 
  are 
  apparently 
  attacked 
  by 
  an 
  as 
  yet 
  undescribed 
  form 
  of 
  

   fungus 
  which 
  has 
  kept 
  them 
  in 
  check. 
  

  

  Isosoma 
  orchidearum, 
  Westw\, 
  has 
  been 
  found 
  on 
  Cattleyas 
  in 
  orchid 
  

   houses 
  in 
  Graz 
  and 
  Pseudococcus 
  nipae, 
  Mask., 
  on 
  Kentias 
  in 
  a 
  

   greenhouse 
  in 
  Vienna. 
  

  

  Heliothrips 
  haemorrhoidalis, 
  Bche., 
  on 
  Kentias 
  was 
  successfully 
  

   treated 
  with 
  lime-sulphur 
  mixture, 
  diluted 
  with 
  35 
  volumes 
  of 
  water 
  and 
  

   suflScient 
  tobacco-extract 
  to 
  form 
  a 
  IJ 
  per 
  cent, 
  solution. 
  Lime- 
  

   sulphur 
  diluted 
  with 
  20-30 
  andeven 
  40 
  volumes 
  of 
  water 
  was 
  also 
  found 
  

   effective 
  against 
  Tetranychus 
  sp., 
  infesting 
  ivy, 
  though 
  how 
  far 
  this 
  is 
  

   to 
  be 
  regarded 
  as 
  a 
  preventive 
  is 
  not 
  yet 
  demonstrated. 
  Cyanide

  Avas 
  tried 
  against 
  Trioza

  Flor, 
  on 
  laurel 
  with 
  

   complete 
  success, 
  but 
  Aonidia 
  lauri, 
  Bche., 
  resisted 
  this 
  treatment 
  to 
  

   a 
  very 
  considerable 
  extent. 
  The 
  American 
  (1:1:3) 
  formula

   method 
  was 
  used.

  The 
  author 
  gives 
  a 
  list 
  of 
  insect 
  species 
  most 
  largely 
  represented 
  

   in 
  the 
  trial 
  trap-trenches 
  at 
  Puschtscha-Woditza, 
  of 
  the 
  Kiev 
  forestry 
  

   district. 
  The 
  trenches 
  were 
  11 
  inches 
  wide 
  and 
  15 
  inches 
  deep. 
  At 
  

   intervals 
  of 
  about 
  9J 
  yards 
  trap-pits, 
  11 
  inches 
  square 
  and 
  15 
  inches 
  

   deep 
  were 
  arranged. 
  Curculionidae 
  were 
  the 
  most 
  numerous, 
  and 
  of 
  

   these 
  Hylobiiis 
  Metis, 
  L., 
  formed 
  67 
  per 
  cent., 
  Coniocleonus 
  glaucus, 
  var. 
  

   turbatus, 
  Fahrs., 
  24 
  per 
  cent., 
  Lepyrus 
  capucinus, 
  Schall, 
  6 
  per 
  cent., 
  and 
  

   Cyphocleonus 
  tigrinus, 
  Panz., 
  3 
  per 
  cent. 
  Other 
  Curculionidae 
  were 
  

   found 
  in 
  negligible 
  quantities. 
  On 
  the 
  12th 
  June 
  1909 
  all 
  the 
  beetles 
  

   present 
  in 
  the 
  traps 
  were 
  counted. 
  The 
  species 
  named 
  above
