  noticed 
  in 
  one 
  mass, 
  is 
  figured. 
  About 
  21 
  per 
  cent, 
  of 
  the 
  eggs 
  

   were 
  infested 
  by 
  parasites, 
  the 
  parasites 
  of 
  the 
  second 
  generation 
  

   attacking 
  also 
  the 
  hosts 
  of 
  the 
  first 
  one. 
  The 
  author 
  corrects 
  a 
  former 
  

   statement 
  of 
  his, 
  that 
  sorghum 
  is 
  not 
  attacked 
  by 
  these 
  caterpillars, 
  

   as 
  it 
  is 
  now 
  found 
  to 
  be 
  one 
  of 
  their 
  food-plants. 
  

  

  Pegomyia 
  hijoscyami, 
  Panz. 
  (Anthomyia 
  conformis, 
  Fall.) 
  Injury 
  to 
  

   the 
  leaves 
  of 
  beet 
  by 
  the 
  larvae 
  of 
  these 
  flies 
  was 
  noticed 
  in 
  May. 
  On 
  

   the 
  lower 
  side 
  of 
  the 
  leaves 
  at 
  the 
  entrance 
  of 
  the 
  mines 
  the 
  empty 
  

   shells 
  of 
  the 
  eggs 
  may 
  be 
  found 
  ; 
  the 
  number 
  of 
  eggs 
  in 
  a 
  mass 
  is 
  from 
  

   2 
  to 
  12, 
  usually 
  4 
  or 
  5 
  ; 
  they 
  are 
  arranged 
  either 
  in 
  two 
  lines 
  or 
  

   irregularly. 
  The 
  eggs 
  were 
  also 
  noticed 
  on 
  leaves 
  of 
  Hyoscyamus 
  niger. 
  

   Oviposition 
  of 
  the 
  first 
  generation 
  extended 
  over 
  two 
  months, 
  the 
  first 
  

   flies 
  of 
  the 
  next 
  generation 
  appearing 
  on 
  26th 
  July. 
  The 
  eggs 
  hatch 
  

   in 
  2 
  to 
  3 
  days 
  and 
  when 
  emerging 
  from 
  the 
  egg, 
  the 
  larva 
  drills 
  a 
  hole 
  

   in 
  the 
  shell, 
  sufficient 
  for 
  its 
  mouth-parts 
  to 
  protrude 
  and 
  seize 
  the 
  

   parenchyma 
  of 
  the 
  leaf 
  ; 
  it 
  then 
  proceeds 
  to 
  mine 
  into 
  the 
  leaf. 
  

   The 
  larvae 
  pass 
  through 
  three 
  stages, 
  moulting 
  twice. 
  About 
  60 
  per 
  

   cent, 
  of 
  these 
  insects 
  were 
  attacked 
  by 
  parasites, 
  sometimes 
  in 
  the 
  

   larval 
  stage. 
  Spraying 
  with 
  barium 
  chloride 
  was 
  tried 
  ; 
  a 
  7 
  per 
  cent, 
  

   solution 
  gave 
  good 
  results, 
  a 
  6 
  per 
  cent, 
  solution 
  killed 
  54 
  per 
  cent, 
  of 
  

   the 
  larvae 
  and 
  a 
  5 
  per 
  cent 
  one 
  destroyed 
  25 
  per 
  cent.

  13 
  species

   and 
  makes 
  some 
  notes 
  with 
  regard 
  to 
  the 
  nomenclature. 
  Aphis 
  

   cKCumeris, 
  Forbes, 
  is 
  stated 
  to 
  be 
  synonymous 
  with 
  Aphis 
  gossypii, 
  

   Glover 
  ; 
  Aphis 
  papaveris 
  and 
  A. 
  rumicis, 
  with 
  A. 
  euonymi 
  papaveris, 
  

   or 
  A. 
  euonymi; 
  Siphonophora 
  pisi, 
  Williams, 
  knovv^n 
  in 
  America 
  

   as 
  Nectarophora 
  pisi, 
  Kalt., 
  is 
  synonymous 
  with 
  Macrosiphum 
  pisi, 
  

   Kalt. 
  

  

  Poeciloscytus 
  cognatus, 
  Fieb. 
  (Capsidae) 
  attacks 
  plants 
  of 
  many 
  

   orders. 
  Destruction 
  of 
  w^eeds 
  and 
  catching 
  by 
  means 
  of 
  movable 
  

   shields 
  moistened 
  with 
  kerosene 
  are 
  recommended 
  as 
  remedies. 
  

   Campylomma 
  verbasci 
  injures 
  beetroot 
  and 
  apple-trees 
  by 
  sucking 
  

   the 
  growing 
  tips 
  and 
  leaves 
  of 
  young 
  seedlings. 
  This 
  pest 
  is 
  found 
  in 
  

   South 
  Russia, 
  W^estern 
  Europe, 
  Caucasia, 
  Turkestan, 
  Algeria 
  and 
  

   North

  The 
  Tyroglyphid 
  mite, 
  Rhizoglyphus 
  echinopus, 
  Fum. 
  & 
  Rob., 
  has 
  

   been 
  noticed 
  yearly 
  on 
  beetroot 
  since 
  1909, 
  and 
  also 
  attacks 
  plants 
  of 
  

   many 
  other 
  orders. 
  

  

  The 
  second 
  part 
  of 
  the 
  report 
  deals 
  with 
  insect 
  pests 
  of 
  plants 
  other 
  

   than 
  beetroot. 
  

  

  Byctiscus 
  betulae, 
  L., 
  injures 
  vines 
  and 
  must 
  be 
  distinguished 
  from 
  

   Rhyachites 
  betulae, 
  Jj. 
  Crioceris 
  12-punctata,Jj., 
  C. 
  li-punctata, 
  Scop., 
  

   and 
  C. 
  b-punctata, 
  Scop., 
  were 
  found 
  on 
  asparagus 
  up 
  to 
  the 
  22nd 
  of 
  

   September 
  ; 
  usually 
  they 
  appear 
  about 
  18th 
  May, 
  the 
  first 
  genera- 
  

   tion 
  damaging 
  the 
  foliage 
  and 
  the 
  second 
  the 
  fruits 
  ; 
  spraying 
  with 
  

   Djipsin 
  is 
  suggested. 
  Dermestes 
  frischi, 
  Kugel, 
  was 
  imported 
  in 
  1913 
  

   from 
  Tiflis 
  in 
  collections 
  of 
  fungi, 
  but 
  has 
  been 
  previously 
  recorded 
  

   near 
  Kiev. 
  Entomoscelis 
  adonidis, 
  Pall., 
  and 
  E. 
  sacra, 
  L., 
  were 
  found 
  

   in 
  small 
  numbers 
  ; 
  it 
  is 
  probable 
  that 
  the 
  adult 
  beetles 
  of 
  the 
  latter 
  

   winter 
  in 
  the 
  earth. 
  Harpalus 
  tardus, 
  Panz., 
  was 
  found 
  last
