  A 
  very 
  useful 
  revision 
  of 
  the 
  American 
  members 
  of 
  this 
  family, 
  which 
  

   contains 
  a 
  number 
  of 
  species 
  that 
  are 
  of 
  economic 
  importance. 
  The 
  

   author 
  recognises 
  22 
  genera 
  and 
  deals 
  with 
  132 
  species, 
  a 
  large 
  propor- 
  

   tion 
  of 
  which 
  are 
  described 
  for 
  the 
  first 
  time.

  The 
  Cattedra 
  Ambulante 
  of 
  Fano 
  gives 
  notice 
  that 
  they 
  wall 
  dis- 
  

   tribute 
  in 
  March, 
  to 
  interested 
  persons 
  who 
  may 
  ask 
  for 
  them, 
  branches 
  

   of 
  mulberry 
  covered 
  with 
  Aulacaspis 
  {Diaspis) 
  pentagona 
  infected 
  

   with 
  Prospaltella 
  berlesei. 
  This 
  branch 
  should 
  be 
  sprayed 
  with 
  pure 
  

   water 
  and 
  fastened 
  with 
  iron 
  wire 
  to 
  any 
  mulberry 
  tree 
  which 
  may 
  

   be 
  seriously 
  attacked 
  by 
  Aulacaspis, 
  within 
  twenty-four 
  hours 
  after 
  

   receipt. 
  A 
  large 
  tree 
  should 
  be 
  selected, 
  capable 
  of 
  furnishing 
  at 
  least 
  

   200 
  branches 
  infested 
  with 
  Aulacaspis 
  of 
  the 
  size 
  of 
  the 
  one 
  received 
  

   from 
  the 
  Station, 
  and 
  the 
  tree 
  must 
  not 
  be 
  treated 
  in 
  any 
  way 
  with 
  

   insecticides 
  or 
  other 
  dressings, 
  nor 
  must 
  it 
  be 
  pruned 
  until 
  next 
  year. 
  

   In 
  March 
  of 
  the 
  following 
  year, 
  all 
  the 
  small 
  branches 
  of 
  this 
  mulberry 
  

   tree 
  are 
  to 
  be 
  cut 
  up 
  into 
  small 
  pieces, 
  and 
  each 
  of 
  these 
  should 
  bear 
  

   a 
  very 
  much 
  larger 
  quantity 
  of 
  Aulacaspis 
  than 
  that 
  received 
  from 
  

   the 
  Station. 
  These 
  pieces 
  are 
  to 
  be 
  used 
  in 
  the 
  same 
  way 
  as 
  the 
  

   original 
  branch, 
  and 
  it 
  is 
  stated 
  that 
  in 
  two 
  years 
  the 
  mulberry 
  trees 
  

   will 
  be 
  completely 
  freed 
  from 
  A. 
  pentagonal 
  Landowners 
  and 
  farmers 
  

   are 
  earnestly 
  requested 
  to 
  examine 
  their 
  mulberry 
  trees, 
  and 
  to 
  do 
  all 
  

   they 
  can 
  to 
  assist 
  in 
  spreading 
  P. 
  berlesei.

  The 
  author's 
  remarks 
  are 
  based 
  on 
  observations 
  and 
  data 
  collected 
  

   during 
  1913. 
  An 
  outbreak 
  of 
  Aporia 
  crataegi 
  may 
  be 
  expected 
  in 
  

   some 
  districts 
  of 
  the 
  government, 
  although 
  last 
  year 
  some 
  40 
  per 
  cent, 
  

   of 
  the 
  caterpillars 
  and 
  pupae 
  perished 
  from 
  pebrine 
  and 
  parasites. 
  

   The 
  Central 
  and 
  Western 
  parts 
  of 
  the 
  government 
  must 
  expect 
  large 
  

   numbers 
  of 
  Cydia 
  pomonella, 
  which 
  yearly 
  does 
  more 
  and 
  more 
  

   damage, 
  so 
  much 
  so 
  that 
  the 
  author 
  thinks 
  that 
  in 
  the 
  near 
  future 
  all 
  

   the 
  orchards 
  will 
  be 
  infested 
  and 
  only 
  the 
  absence 
  of 
  apples 
  will 
  then 
  

   stop 
  its 
  further 
  development. 
  Only 
  30 
  per 
  cent, 
  of 
  caterpillars 
  and 
  

   pupae 
  of 
  Hyponomeuta 
  malinellus 
  were 
  destroyed 
  last 
  year 
  by 
  parasites, 
  

   so 
  this 
  pest 
  may 
  again 
  appear 
  everywhere. 
  The 
  same 
  is 
  also 
  the 
  case 
  

   with 
  regard 
  to 
  Anthonomus 
  pomorum, 
  which 
  last 
  year 
  destroyed 
  in 
  

   some 
  orchards 
  30-40 
  per 
  cent, 
  of 
  the 
  yield, 
  while 
  in 
  others 
  this 
  figure 
  

   reached 
  60 
  per 
  cent., 
  notwithstanding 
  the 
  fact 
  that 
  63 
  per 
  cent, 
  of 
  its
