  Blennocampa 
  jnisilla, 
  are 
  laid 
  in 
  May 
  on 
  the 
  leaves, 
  which 
  the 
  

   larvae 
  cause 
  to 
  roll 
  up 
  so 
  tightly 
  that 
  spraying 
  is 
  useless, 
  and 
  the 
  

   hand-picking 
  of 
  the 
  rolled 
  leaves 
  and 
  burning 
  them 
  is 
  all 
  that 
  

   can 
  be 
  done. 
  This 
  should 
  be 
  attended 
  to 
  as 
  soon 
  as 
  any 
  sign 
  of 
  

   attack 
  manifests 
  itself, 
  otherwise 
  the 
  larvae 
  will 
  mature 
  and 
  drop 
  to 
  

   the 
  ground 
  to 
  pupate. 
  Against 
  the 
  Aphids, 
  Siphonophora 
  rosae 
  and 
  

   S. 
  rosarum, 
  a 
  spray 
  prepared 
  with 
  4^ 
  lb. 
  soft 
  soap 
  and 
  l.| 
  pints 
  crude 
  

   spirit 
  in 
  19 
  gallons 
  of 
  water 
  is 
  recommended. 
  For 
  roses 
  grown 
  

   under 
  glass 
  the 
  quantities 
  of 
  soap 
  and 
  spirit 
  may 
  be 
  reduced 
  to 
  half. 
  

   Against 
  Tetranychus 
  telarius, 
  a 
  winter 
  dressing 
  with 
  6 
  per 
  cent, 
  car- 
  

   bohneum 
  is 
  recommended. 
  Another 
  good 
  plan 
  is 
  to 
  dust 
  the 
  plants 
  

   with 
  sulphur 
  or 
  to 
  spray 
  mth 
  Cahfornian 
  mixture 
  [see

  Review, 
  

   Ser.

  1 
  part 
  in 
  35 
  parts 
  of 
  water. 
  Typhlocyba 
  rosae, 
  

   both 
  as 
  nymph 
  and 
  perfect 
  insect, 
  attacks 
  the 
  underside 
  of 
  the 
  leaves, 
  

   especially 
  along 
  the 
  principal 
  veins, 
  and 
  if 
  numerous, 
  does 
  great 
  

   damage. 
  As 
  the 
  eggs 
  are 
  laid 
  on 
  the 
  ends 
  of 
  the 
  branches, 
  a 
  dressing 
  

   of 
  6 
  per 
  cent, 
  carbolineum 
  may 
  be 
  useful 
  as 
  a 
  remedy, 
  and 
  this 
  should 
  

   be 
  applied 
  as 
  soon 
  as 
  the 
  first 
  white 
  spots 
  are 
  seen 
  on 
  the 
  leaves, 
  as 
  

   this 
  indicates 
  the 
  presence 
  of 
  the 
  insect.

  C. 
  brumata 
  is 
  a 
  very 
  widespread 
  pest 
  in 
  Holland 
  in 
  orchards, 
  

   nurseries 
  and 
  forests, 
  and 
  the 
  damage 
  done 
  is 
  very 
  considerable. 
  

   One 
  of 
  the 
  most 
  practical 
  remedies 
  consists 
  in 
  the 
  use 
  of 
  sticky 
  bands 
  

   upon 
  the 
  trees, 
  and 
  these 
  must 
  be 
  attached 
  to 
  the 
  trees 
  in 
  such 
  a 
  way 
  

   that 
  the 
  caterpillars 
  cannot 
  creep 
  up 
  between 
  the 
  paper 
  and 
  the 
  bark. 
  

   The 
  band 
  should 
  be 
  placed 
  about 
  3 
  feet 
  above 
  the 
  soil, 
  or 
  higher 
  if 
  

   cattle 
  are 
  grazed 
  in 
  the 
  orchard. 
  It 
  is 
  also 
  well 
  to 
  place 
  bands 
  on 
  

   3 
  or 
  4 
  of 
  the 
  larger 
  branches, 
  and 
  if 
  the 
  infestation 
  be 
  very 
  serious, 
  

   two 
  bands 
  on 
  each 
  trunk. 
  Shade 
  trees, 
  elms, 
  willows, 
  etc., 
  in 
  the 
  hedges 
  

   round 
  the 
  orchard 
  should 
  also 
  be 
  banded. 
  Bush 
  fruit 
  which 
  cannot 
  

   be 
  banded 
  may 
  be 
  sprayed 
  with 
  1 
  ounce 
  of 
  Paris 
  green 
  and 
  1-2 
  lb. 
  of 
  

   lime 
  in 
  19 
  gallons 
  of 
  water, 
  or 
  with 
  1 
  lb. 
  of 
  lead 
  arsenate 
  in 
  the 
  same 
  

   quantity 
  of 
  water. 
  Spraying 
  with 
  these 
  poisonous 
  substances 
  should 
  

   not 
  be 
  done 
  within 
  5 
  weeks 
  of 
  the 
  time 
  at 
  which 
  the 
  fruit 
  is 
  hkely 
  to 
  

   be 
  gathered. 
  

  

  The 
  operations 
  against 
  CJieimatohia 
  brumata 
  also 
  apply 
  to 
  Hybernia 
  

   (Fidonia) 
  defoliaria 
  and 
  Anisopteryx 
  aescularia. 
  The 
  latter 
  generally 
  

   makes 
  its 
  appearance 
  at 
  the 
  end 
  of 
  winter 
  or 
  very 
  early 
  in 
  spring.

  The 
  sawfly, 
  Cephus 
  pygmaeus, 
  is 
  a 
  well-known 
  cereal 
  pest, 
  though 
  

   allied 
  species 
  are 
  not 
  of 
  sufficiently 
  frequent 
  occurrence 
  to 
  be 
  feared 
  

   as 
  yet. 
  The 
  larvae 
  of 
  many 
  species 
  attack 
  young 
  rose 
  shoots. 
  Two 
  

   North 
  American 
  species 
  of 
  the 
  allied 
  genus 
  Janus 
  attack 
  currants 
  and 
  

   osiers 
  in 
  this 
  manner, 
  whilst
