  The 
  second 
  generation 
  of 
  Lithocolletis 
  populifoliella 
  Fr., 
  [see 
  this 
  

   Review, 
  Ser. 
  A, 
  i, 
  p. 
  495] 
  was 
  more 
  numerous 
  than 
  the 
  first 
  one, 
  not- 
  

   withstanding 
  that 
  35-40 
  per 
  cent, 
  of 
  the 
  latter 
  were 
  infested 
  by 
  

   parasites. 
  In 
  August, 
  most 
  of 
  the 
  poplar 
  trees 
  in 
  Charkov 
  were 
  

   devastated 
  and 
  the 
  plague 
  spread 
  along 
  the 
  railway 
  line 
  as 
  far 
  as 
  the 
  

   station 
  of 
  Meref 
  ; 
  it 
  was 
  noticed 
  that 
  the 
  poplar 
  trees 
  situated 
  along 
  

   the 
  line 
  have 
  suffered 
  most, 
  the 
  damage 
  disappearing 
  totally 
  at 
  a 
  

   distance 
  of 
  600 
  yards 
  from 
  the 
  line 
  ; 
  solitary 
  trees 
  or 
  isolated 
  avenues 
  

   have 
  also 
  suffered 
  more 
  than 
  dense 
  groups 
  of 
  trees, 
  which 
  sometimes 
  

   were 
  not 
  affected 
  at 
  all. 
  The 
  greatest 
  injury 
  was 
  done 
  to 
  " 
  balsam 
  

   poplar 
  " 
  {Populus 
  balsamifera), 
  the 
  least 
  to 
  " 
  silver 
  poplar" 
  ; 
  the 
  first 
  

   generation 
  did 
  not 
  attack 
  the 
  latter 
  trees 
  at 
  all 
  and 
  even 
  the 
  second 
  

   one 
  attacked 
  them 
  only 
  where 
  all 
  the 
  other 
  varieties 
  of 
  poplar 
  were 
  

   overcrowded 
  with 
  caterpillars. 
  Besides 
  poplar 
  trees, 
  the 
  pests 
  attacked 
  

   also 
  some 
  varieties 
  of 
  Avillow, 
  but 
  the 
  caterpillars 
  on 
  the 
  latter 
  usually 
  

   perished 
  without 
  becoming 
  adult. 
  The 
  second 
  generation 
  appeared 
  on 
  

   the 
  28th 
  August, 
  but 
  in 
  the 
  middle 
  of 
  September 
  some 
  of 
  the 
  moths 
  

   had 
  not 
  emerged 
  and 
  even 
  adult 
  caterpillars 
  were 
  still 
  found. 
  The 
  

   second 
  generation 
  was 
  infested 
  with 
  parasites 
  to 
  the 
  extent 
  of 
  98 
  

   per 
  cent., 
  most 
  of 
  them 
  being 
  ectoparasites. 
  The 
  author 
  has 
  noticed 
  

   that 
  the 
  caterpillars 
  get 
  into 
  cracks 
  of 
  the 
  bark, 
  and 
  recommends 
  

   smearing 
  the 
  trees 
  in 
  late 
  autumn 
  or 
  early 
  spring 
  with 
  " 
  wolf's 
  paste 
  " 
  

   as 
  a 
  preventive 
  measure.

  Haltica, 
  Clysia 
  ambiguella, 
  Polychrosis 
  botrana, 
  Sparganothis 
  and 
  

   CocciDAE 
  are 
  the 
  insects 
  the 
  winter 
  treatment 
  of 
  which 
  is 
  

   discussed. 
  One 
  method 
  is 
  directed 
  against 
  the 
  sites 
  of 
  hibernation 
  

   by 
  using 
  shelter 
  traps 
  or 
  undertaking 
  decortication. 
  The 
  other 
  

   method 
  includes 
  washing 
  with 
  insecticides 
  or 
  hot 
  water 
  and 
  

   fumigation, 
  and 
  aims 
  at 
  destropng 
  the 
  pests 
  in 
  situ. 
  If 
  shelter 
  

   traps 
  are 
  used 
  against 
  Haltica 
  they 
  must 
  be 
  placed 
  not 
  later 
  than 
  

   August 
  ; 
  natural 
  shelters 
  (bushes, 
  grass, 
  cracks 
  in 
  the 
  ground, 
  etc.) 
  

   must 
  be 
  eUminated 
  and 
  the 
  area 
  under 
  treatment 
  must 
  be 
  as 
  

   extended 
  as 
  possible. 
  The 
  latter 
  conditions 
  can 
  only 
  be 
  satisfied
