  the 
  ravages 
  of 
  harmful 
  insects. 
  Although 
  they 
  eat 
  fruit 
  and 
  berries 
  

   they 
  prefer 
  animal 
  food, 
  particularly 
  insects, 
  including 
  the 
  follo'v\ing 
  

   important 
  pests 
  : 
  — 
  Grasshoppers, 
  ants, 
  potato 
  beetle 
  (Leptinotarsa 
  

   decemlineata), 
  plum 
  curculio 
  {Conotrachelus 
  nenuphar), 
  clover-leaf 
  

   weevil, 
  may 
  beetle 
  (Lachnosterna 
  sp.), 
  com 
  weevil 
  (Calandra 
  sp.), 
  

   alfalfa 
  weevil, 
  army 
  worm, 
  cutworms, 
  codHng 
  moth 
  {Cydia 
  ponionella), 
  

   cabbage 
  worm, 
  chinch 
  bug 
  {Blissus 
  leucoptera), 
  black 
  oHve 
  scale 
  

   (Saissetia 
  oleae), 
  etc. 
  If 
  they 
  become 
  too 
  numerous 
  they 
  are 
  obHged 
  

   to 
  seek 
  for 
  food 
  in 
  the 
  orchards 
  and 
  are 
  destructive 
  to 
  fruit, 
  but 
  in 
  this 
  

   case 
  they 
  are 
  best 
  kept 
  off 
  with 
  scarecrows 
  and 
  should 
  not 
  be 
  killed.

  This 
  new 
  species, 
  which 
  the 
  author 
  proposes 
  to 
  call 
  Coccus 
  ciiricola, 
  

   was 
  first 
  identified 
  as 
  C 
  longulus, 
  Doug., 
  and 
  later 
  as 
  C. 
  elongatus, 
  

   Sign. 
  It 
  occurs 
  in 
  various 
  parts 
  of 
  Cahfornia, 
  where 
  it 
  is 
  probable 
  

   that 
  in 
  the 
  past 
  it 
  has 
  been 
  confused 
  with 
  C. 
  hesperidum, 
  L. 
  C. 
  

   citricola 
  has 
  hitherto 
  been 
  only 
  found 
  on 
  the 
  leaves 
  and 
  twigs 
  of 
  citrus 
  

   trees. 
  The 
  young 
  scales 
  settle 
  mostly 
  on 
  the 
  leaves 
  and 
  when 
  about 
  

   half-grown 
  migrate 
  to 
  the 
  small 
  twigs. 
  No 
  scales 
  have 
  been 
  found 
  

   on 
  twigs 
  larger 
  than 
  one-half 
  inch 
  in 
  diameter, 
  and 
  the 
  infestations 
  are 
  

   largely 
  confined 
  to 
  the 
  lower 
  half 
  of 
  the 
  tree. 
  They 
  are 
  usually 
  

   abundant, 
  and 
  are 
  arranged 
  on 
  the 
  twigs 
  in 
  a 
  curiously 
  imbricated 
  

   and 
  quite 
  characteristic 
  manner.

  The 
  author 
  refers 
  to 
  the 
  law 
  of 
  the 
  26th 
  June 
  1913, 
  dealing 
  with 
  

   plant 
  pest 
  control, 
  one 
  of 
  the 
  clauses 
  of 
  which 
  provides 
  that 
  a 
  state 
  

   subsidy 
  of 
  up 
  to 
  50 
  per 
  cent, 
  of 
  the 
  cost 
  may 
  be 
  granted 
  in 
  cases 
  where 
  

   universal 
  control 
  is 
  required. 
  Another 
  clause 
  gives 
  the 
  authorities 
  

   power 
  to 
  compel 
  agriculturists 
  to 
  form 
  an 
  association 
  where 
  the 
  lack 
  

   of 
  such 
  an 
  association 
  involves 
  danger 
  to 
  agricultural 
  interests.

  Besides 
  causing 
  direct 
  injury, 
  Saissetia 
  (Lecanium) 
  oleae 
  favours 
  

   the 
  sooty 
  fungus, 
  and 
  is 
  thus 
  doubly 
  harmful. 
  To 
  ascertain 
  the 
  correct 
  

   date 
  for 
  beginning 
  control, 
  MartelU 
  advises 
  that 
  small 
  pieces 
  of 
  twigs 
  

   be 
  cut 
  from 
  badly 
  infested 
  trees 
  and 
  placed 
  under 
  a 
  glass 
  tumbler 
  

   on 
  a 
  sheet 
  of 
  white 
  paper. 
  The 
  contents 
  are 
  carefully 
  watched 
  daily, 
  

   and 
  when 
  a 
  number 
  of 
  small 
  reddish 
  insects 
  are 
  observed 
  at 
  the 
  top 
  or 
  

   on 
  the 
  side 
  nearest 
  the 
  light, 
  spraying 
  should 
  begin 
  with 
  the 
  same 
  lime- 
  

   sulphur 
  as 
  that 
  used 
  against 
  Chrysomphalus 
  dictyospermi.
