  The 
  author 
  cites 
  a 
  case 
  of 
  two 
  closely 
  allied 
  weevils, 
  which 
  are 
  

   parasitised 
  by 
  different 
  insects 
  ; 
  these 
  are 
  Hypera 
  postica, 
  Gyl., 
  and 
  

   H. 
  punctata, 
  F. 
  The 
  former 
  is 
  infested 
  by 
  several 
  parasites, 
  among 
  which 
  

   nine 
  are 
  frequent 
  and 
  easily 
  distinguished 
  ; 
  three 
  attack 
  the 
  eggs 
  and 
  

   six 
  (including 
  a 
  fungus) 
  the 
  larvae 
  and 
  pupae. 
  Hypera 
  punctata, 
  on 
  

   the 
  contrary, 
  is 
  only 
  parasitised 
  by 
  three 
  species, 
  even 
  when 
  it 
  is 
  in 
  

   the 
  same 
  fields 
  as 
  H. 
  postica 
  ; 
  these 
  three 
  are 
  a 
  Mymarid 
  egg-parasite, 
  

   a 
  fungus, 
  and 
  an 
  Ichneumon 
  parasite 
  of 
  the 
  larvae. 
  The 
  first 
  two 
  are 
  

   also 
  parasitic 
  upon 
  H. 
  postica 
  ; 
  the 
  last 
  is 
  a 
  specific 
  parasite 
  of 
  

   H. 
  punctata.

  Between 
  January 
  and 
  June, 
  1912, 
  the 
  author 
  made 
  a 
  series 
  of 
  

   observations 
  upon 
  the 
  locust 
  (Locusta 
  danica) 
  in 
  North 
  Queensland. 
  

   In 
  January 
  adult 
  specimens 
  were 
  observed 
  in 
  swarms, 
  apparently 
  

   attracted 
  by 
  the 
  lights 
  in 
  houses. 
  Later 
  in 
  the 
  month, 
  at 
  Innisfail, 
  

   from 
  the 
  bank 
  of 
  the 
  Johnstone 
  river, 
  quite 
  a 
  large 
  progressive 
  flight 
  

   was 
  witnessed 
  ; 
  in 
  an 
  adjacent 
  sugar 
  plantation 
  most 
  of 
  the 
  plants 
  

   withered 
  on 
  the 
  next 
  day, 
  the 
  leaves 
  having 
  been 
  stripped 
  of 
  their 
  mid- 
  

   ribs. 
  In 
  February, 
  the 
  young 
  were 
  noticed, 
  and 
  at 
  the 
  same 
  time 
  

   many 
  dead 
  adults, 
  mostly 
  females, 
  w^ere 
  found. 
  These 
  were 
  found 
  

   while 
  ovipositing, 
  with 
  their 
  abdomens 
  half-buried 
  in 
  the 
  earth. 
  

   These 
  adults 
  were 
  no 
  doubt 
  the 
  last 
  of 
  the 
  migrating 
  swarms 
  observed 
  

   in 
  January. 
  In 
  March 
  the 
  adults 
  of 
  the 
  first 
  generation 
  were 
  very 
  

   abundant, 
  and 
  also 
  all 
  larval 
  stages, 
  but 
  in 
  April 
  all 
  had 
  reached 
  

   maturity. 
  At 
  this 
  time 
  injury 
  to 
  cane 
  was 
  noticeable 
  and 
  rather 
  

   extensive. 
  In 
  April, 
  eggs 
  of 
  some 
  locust, 
  probably 
  those 
  of 
  L, 
  danica, 
  

   were 
  found, 
  and 
  an 
  egg-parasite 
  {Scelio 
  ovi, 
  Girault 
  M.S.) 
  was 
  reared 
  

   from 
  them. 
  Later, 
  this 
  parasite, 
  together 
  mth 
  another 
  species 
  (Scelio 
  

   australis, 
  Froggatt), 
  known 
  to 
  be 
  parasitic 
  upon 
  the 
  eggs 
  of 
  X. 
  australis, 
  

   was 
  found 
  in 
  company 
  with 
  the 
  locusts. 
  In 
  May 
  and 
  June, 
  L. 
  danica 
  

   were 
  rare, 
  although 
  larvae 
  of 
  australis 
  were 
  seen 
  in 
  colonies.

  The 
  life-history 
  and 
  occurrence 
  of 
  Aphis 
  euonymi 
  have 
  been 
  given 
  by 
  

   Mordwilko. 
  He 
  was 
  of 
  the 
  opinion 
  that 
  this 
  insect, 
  which 
  causes 
  

   extensive 
  damage 
  to 
  beetroot 
  plantations, 
  had 
  two 
  plant 
  hosts 
  during 
  

   its 
  life-cycle 
  — 
  the 
  beetroot 
  and 
  Viburnum 
  opuliis, 
  L. 
  or 
  Euonymus 
  

   europaeus, 
  L., 
  and 
  that 
  by 
  destroying 
  the 
  latter 
  trees 
  in 
  the 
  neighbour- 
  

   hood 
  of 
  beet 
  plantations, 
  the 
  pest 
  could 
  be 
  got 
  rid 
  of. 
  The 
  present 
  

   author 
  has 
  made 
  further 
  observations 
  at 
  Orleans 
  and 
  at 
  St. 
  Germain- 
  

   des-Pres, 
  and 
  has 
  found 
  that 
  there 
  are 
  yet 
  other 
  alternative 
  hosts 
  

   besides 
  the 
  two 
  mentioned 
  above, 
  viz., 
  Fusain 
  de 
  Japon, 
  Rumex, 
  

   Chenopodium 
  and 
  other 
  wild 
  plants, 
  so 
  that 
  destroying 
  the 
  Viburnum 
  

   or 
  Euonymus 
  is 
  by 
  no 
  means 
  a 
  sufficient 
  remedy.
