  pest 
  of 
  the 
  plum 
  was 
  Hyalopterus 
  arundinis, 
  the 
  mealy 
  plum-aphis, 
  

   while 
  cabbages 
  and 
  turnips 
  were 
  injured 
  by 
  Chortophila 
  brassicae. 
  The 
  

   fruit-leaf 
  beetle, 
  Syneta 
  albida, 
  was 
  reported 
  as 
  damaging 
  strawberries 
  

   and 
  clover 
  and 
  no 
  method 
  of 
  controlling 
  it 
  has 
  been 
  found 
  [see 
  this 
  

   Review, 
  Ser. 
  A, 
  i, 
  p. 
  413]. 
  The 
  flea-beetle, 
  Epitrix 
  suhcrinita, 
  fed 
  

   freely 
  on 
  tomatoes, 
  potatoes 
  and 
  various 
  weeds, 
  and 
  the 
  bronze 
  apple- 
  

   borer, 
  Magdalis 
  aenescens, 
  was 
  commonly 
  found 
  boring 
  into 
  the 
  

   injured 
  wood 
  of 
  apple-trees. 
  The 
  most 
  common 
  and 
  injurious 
  Elaterid 
  

   is 
  Corymhites 
  inflatus, 
  but 
  in 
  the 
  spring 
  a 
  very 
  severe 
  infestation 
  of 
  

   Cardiophorus 
  fenestratus 
  occurred 
  ; 
  other 
  species 
  occurring 
  in 
  orchards 
  

   in 
  the 
  Okanagan 
  are 
  : 
  Corymhites 
  morulus, 
  C. 
  fallax, 
  C. 
  maurus, 
  

   C.furtivus, 
  C. 
  conjungens, 
  C. 
  aeripennis, 
  C. 
  cruciatus, 
  C. 
  triundulatus, 
  

   Cardiophorus 
  tenebrosus, 
  C. 
  tumidicollis, 
  Elater 
  nigrinus, 
  Dolopius 
  

   lateralis, 
  Limonius 
  pilosus 
  (infuscatus), 
  L. 
  discoideus, 
  L. 
  venablesi 
  and 
  

   L. 
  canus. 
  The 
  grey 
  leaf-beetle, 
  Glyptoscelis 
  pubescens 
  (?) 
  is 
  present 
  in 
  

   abundance 
  in 
  the 
  spring, 
  feeding 
  mainly 
  on 
  Balsamorrhiza 
  sagittata, 
  

   but 
  occasionally 
  on 
  apple 
  foliage. 
  Hylemyia 
  antiqua 
  (Pegomyia 
  ceparum) 
  

   the 
  onion 
  maggot, 
  was 
  fairly 
  common, 
  and 
  onions 
  were 
  also 
  attacked 
  

   by 
  the 
  hyacinth 
  mite, 
  Rhizoglyphus 
  hyacinthi, 
  which 
  had 
  in 
  many 
  

   cases 
  burrowed 
  deep 
  into 
  the 
  root. 
  Red 
  spider, 
  Tetranychus 
  bimacu- 
  

   latus, 
  was 
  responsible 
  for 
  more 
  damage 
  than 
  the 
  almond 
  mite, 
  Bryobia 
  

   pratensis, 
  and 
  in 
  a 
  few 
  isolated 
  cases 
  Eriophyes 
  pyri, 
  the 
  pear-leaf 
  

   blister-mite, 
  severely 
  injured 
  pears, 
  but 
  has 
  never 
  been 
  found 
  attacking 
  

   apple-trees 
  in 
  British 
  Columbia. 
  The 
  rusty-leaf 
  mite, 
  Phyllocoptes 
  

   schlectendali, 
  Nalepa, 
  feeds 
  upon 
  the 
  upper 
  surface 
  of 
  the 
  apple 
  leaves 
  ; 
  

   in 
  some 
  cases, 
  attacked 
  leaves 
  are 
  of 
  a 
  red 
  rusty 
  colour, 
  but 
  more 
  often 
  

   have 
  a 
  silvery 
  appearance 
  which 
  is 
  invariably 
  confused 
  with 
  the 
  

   disease 
  called 
  " 
  silver-leaf." 
  In 
  the 
  case 
  of 
  " 
  silver-leaf," 
  however, 
  

   the 
  entire 
  leaf 
  is 
  uniformly 
  silvered, 
  with 
  a 
  milky 
  gloss, 
  while 
  when 
  

   the 
  attack 
  is 
  due 
  to 
  the 
  mite, 
  it 
  is 
  usually 
  more 
  or 
  less 
  patchy, 
  with 
  a 
  

   metallic 
  lustre 
  ; 
  a 
  very 
  bad 
  attack 
  of 
  T. 
  bimacidatus 
  frequently 
  pro- 
  

   duces 
  a 
  sheen 
  on 
  plum 
  leaves. 
  A 
  mite, 
  considered 
  by 
  Dr. 
  Banks 
  to 
  be 
  

   probably 
  Eriophyes 
  malifoliae, 
  was 
  found 
  hidden 
  in 
  the 
  pubescence 
  

   on 
  the 
  under-side 
  of 
  apple 
  leaves, 
  and 
  when 
  present 
  in 
  large 
  numbers 
  

   the 
  entire 
  leaf 
  may 
  wither 
  and 
  turn 
  brown, 
  the 
  work 
  often 
  being 
  

   mistaken 
  for 
  apple 
  scab.

  This 
  paper 
  records 
  the 
  results 
  of 
  the 
  past 
  two 
  seasons' 
  observations 
  

   on 
  the 
  insects 
  of 
  economic 
  importance 
  occurring 
  in 
  the 
  Lower 
  Fraser 
  

   Valley. 
  Eucosma 
  (Tmetocera) 
  ocellana, 
  Schiff., 
  the 
  eye-spotted 
  bud- 
  

   moth, 
  ranks 
  first 
  among 
  the 
  insect 
  pests 
  of 
  the 
  apple 
  in 
  the 
  Fraser 
  

   Valley 
  ; 
  Enarmonia 
  prunivora, 
  Walsh, 
  occurs, 
  but 
  its 
  life- 
  history 
  under 
  

   local 
  conditions 
  is 
  but 
  imperfectly 
  known. 
  A 
  leaf 
  -roller 
  of 
  the 
  genus 
  

   Olethreutes, 
  which 
  resembles 
  the 
  bud-moth 
  in 
  habits, 
  has 
  been 
  observed 
  

   in 
  small 
  numbers, 
  and 
  in 
  recent 
  years 
  the 
  fall 
  web-worm, 
  Hyphantria 
  

   cunea, 
  Dru., 
  the 
  tent 
  caterpillar, 
  Malacosoma 
  erosa. 
  Stretch, 
  and 
  the 
  

   apple 
  fruit-miner, 
  Argyresthia 
  conjugella, 
  Z., 
  have 
  been 
  less 
  common. 
  

   No 
  occurrence 
  of 
  the 
  cherry 
  fruit-fly, 
  Rhagoletis 
  cingulata, 
  Lw., 
  has
