  Two 
  undetermined 
  Hymenopterous 
  parasites 
  have 
  been 
  captured, 
  

   one 
  on 
  the 
  hibernating 
  nymphs, 
  and 
  one 
  on 
  the 
  eggs. 
  Chilocorus 
  

   bivulnerus, 
  is 
  also 
  predaceous 
  on 
  the 
  young 
  stages. 
  After 
  somewhat 
  

   extensive 
  sprajdng 
  experiments, 
  the 
  author 
  recommends 
  a 
  thorough 
  

   spraying 
  in 
  March, 
  using 
  any 
  of 
  the 
  three 
  following 
  formulae 
  : 
  (a) 
  

   Schnarr's 
  Insecticide, 
  1 
  to 
  20. 
  (6) 
  Junior 
  red 
  engine 
  oil, 
  2 
  gallons 
  ; 
  

   whale-oil 
  soap, 
  1 
  gallon 
  ; 
  water, 
  50 
  gallons, 
  (c) 
  Diamond 
  paraffin 
  oil, 
  

   2 
  gallons 
  ; 
  whale-oil 
  soap, 
  1 
  gallon 
  ; 
  water, 
  50 
  gallons. 
  In 
  preparing 
  

   (6) 
  and 
  (c) 
  the 
  oil 
  should 
  be 
  slowly 
  added 
  to 
  the 
  soap 
  solution 
  and 
  when 
  

   thoroughly 
  mixed, 
  about 
  3 
  quarts 
  of 
  water 
  should 
  be 
  added 
  slowly 
  and 
  

   the 
  whole 
  emulsified 
  ; 
  dilute 
  to 
  50 
  gallons 
  and 
  the 
  mixture 
  is 
  ready 
  for 
  

   use. 
  One 
  thorough 
  apphcation 
  every 
  four 
  or 
  five 
  years, 
  wetting 
  all 
  

   sides 
  of 
  all 
  twigs, 
  will 
  control 
  this 
  pest, 
  as 
  the 
  scale 
  spreads 
  very 
  slowly 
  

   from 
  tree 
  to 
  tree.

  In 
  this 
  monograph 
  a 
  complete 
  rearrangement 
  of 
  the 
  genera 
  of 
  

   Psyllidae 
  is 
  presented, 
  and 
  the 
  American 
  genera 
  have 
  been 
  arranged 
  

   in 
  six 
  sub-famihes, 
  viz. 
  : 
  — 
  Liviinae, 
  Pauropsyllinae, 
  Carsidarinae, 
  

   Ceriacreminae, 
  Triozinae 
  and 
  Psyllinae. 
  Some 
  of 
  these 
  are 
  new 
  

   names, 
  and 
  those 
  which 
  have 
  already 
  been 
  used 
  have 
  here 
  difierent 
  

   limits. 
  The 
  old 
  subfamily, 
  Aphalarinae, 
  is 
  not 
  recognised, 
  and 
  the 
  

   genus 
  Aphalara 
  has 
  been 
  transferred 
  to 
  the 
  Liviinae, 
  and 
  the 
  other 
  

   genera 
  formerly 
  placed 
  in 
  it 
  have 
  been 
  referred 
  to 
  Psyllinae 
  or 
  

   other 
  subfamiHes. 
  After 
  deahng 
  with 
  the 
  morphology 
  of 
  these 
  insects 
  

   and 
  their 
  relations 
  to 
  other 
  Homoptera, 
  the 
  author 
  describes 
  a 
  large 
  

   number 
  of 
  species, 
  many 
  being 
  new.

  An 
  unusual 
  outbreak 
  is 
  recorded 
  in 
  northern 
  Pennsylvania 
  of 
  the 
  

   Bed 
  Leaf 
  Beetle 
  (Galericcella 
  rufosanguinea), 
  which 
  eats 
  the 
  foliage 
  

   of 
  cherry, 
  peach, 
  apple 
  and 
  grapes, 
  and 
  has 
  already 
  done 
  such 
  damage 
  

   that 
  it 
  will 
  seriously 
  check 
  the 
  growth 
  and 
  development 
  of 
  the 
  trees. 
  

   Trees 
  should 
  be 
  sprayed 
  at 
  once, 
  using 
  two 
  pounds 
  of 
  lead 
  arsenate 
  in 
  

   50 
  U.S. 
  gallons 
  (42J

  care 
  being 
  taken 
  to

   sides 
  of 
  the 
  leaves.

  In 
  the 
  " 
  dark-tobacco 
  " 
  districts 
  of 
  Kentucky 
  and 
  Tennessee 
  

   tobacco 
  hornworms 
  (Phlegethontius 
  quinquemaculata, 
  Haw., 
  and 
  

   P. 
  sexta, 
  Joh.), 
  are 
  the 
  most 
  serious 
  problem 
  of 
  the 
  tobacco-grower. 
  

   Hand-picking 
  being 
  no 
  longer 
  practicable, 
  owing 
  to 
  the 
  scarcity 
  and 
  

   inefficiency 
  of 
  labour, 
  growers 
  have 
  been 
  forced 
  to 
  employ 
  an 
  insecticide.
