﻿upon 
  the 
  grass 
  and 
  these 
  were 
  observed 
  by 
  Mr. 
  Koebcle 
  to 
  be 
  par- 
  

   asitized 
  by 
  llymenoptera. 
  No 
  one 
  in 
  AustraUa 
  seems 
  to 
  have 
  

   ever 
  stiuHed 
  the 
  parasites 
  of 
  Fulg-oridae 
  to 
  any 
  extent. 
  After 
  

   leaving 
  Sydney, 
  the 
  next 
  ten 
  days 
  were 
  spent 
  at 
  Lirisliane 
  and 
  in 
  

   the 
  Botanical 
  Gardens 
  the 
  first 
  cane 
  was 
  observed 
  and 
  a 
  few 
  

   hoppers 
  noticed 
  upon 
  it. 
  Here, 
  also, 
  were 
  found 
  the 
  dipterous 
  

   parasites 
  of 
  leaf-hoppers 
  ; 
  some 
  of 
  these 
  parasites, 
  the 
  maggot 
  of 
  

   wiiich 
  lives 
  within 
  the 
  body 
  of 
  the 
  hopper, 
  might 
  have 
  proved 
  

   useful 
  here, 
  but 
  the 
  work 
  of 
  collecting 
  and 
  introducing 
  them 
  suc- 
  

   cessfully 
  would 
  have 
  taken 
  months 
  of 
  exclusive 
  labor 
  and 
  then 
  

   might 
  have 
  failed. 
  It 
  was 
  cold 
  and 
  even 
  frosty 
  there. 
  

  

  "Bundaberg 
  was 
  the 
  next 
  stop 
  ; 
  it 
  was 
  very 
  warm 
  at 
  midday 
  

   and 
  very 
  cold 
  at 
  night, 
  the 
  latter 
  so 
  much 
  so 
  that 
  the 
  cane 
  was 
  

   turned 
  yellow. 
  Leaf-hoppers 
  were 
  found 
  in 
  the 
  cane 
  fields 
  and 
  

   Mr. 
  Koebele 
  verified 
  his 
  prediction 
  by 
  breeding 
  some 
  two 
  or 
  three 
  

   species 
  of 
  hopper-egg 
  parasites 
  from 
  eggs 
  collected 
  there. 
  In 
  our 
  

   anxiety 
  to 
  get 
  north 
  we 
  stopped 
  but 
  ten 
  days. 
  

  

  "One 
  day 
  was 
  spent 
  at 
  Townsville 
  ; 
  this 
  place 
  was 
  found 
  very 
  

   dry 
  and 
  bare 
  ; 
  no 
  green 
  grass, 
  no 
  cane. 
  The 
  most 
  noticeable 
  thing 
  

   was 
  a 
  row 
  of 
  fig-trees, 
  the 
  leaves 
  black 
  with 
  fungus, 
  on 
  which 
  Si- 
  

   phantas 
  had 
  previously 
  swarmed. 
  These, 
  however, 
  had 
  been 
  badly 
  

   parasitized 
  and 
  numerous 
  cocoons 
  of 
  the 
  parasite 
  plastered 
  the 
  

   leaves. 
  

  

  "At 
  Cairns, 
  systematic 
  work 
  on 
  cane- 
  and 
  other 
  leaf-hoppers 
  

   was 
  begun 
  ; 
  the 
  cane 
  was 
  found 
  to 
  be 
  inhabited 
  by 
  half 
  a 
  dozen 
  of 
  

   these, 
  all 
  about 
  equally 
  numerous, 
  and 
  none 
  injurious. 
  Most 
  con- 
  

   spicuous 
  in 
  the 
  cane 
  was 
  a 
  blue 
  lady-bird 
  collected 
  by 
  Koebele 
  

   years 
  ago, 
  and 
  determined 
  by 
  Blackburn 
  as 
  Orcus 
  ovalis. 
  It 
  

   feeds 
  on 
  the 
  rust 
  of 
  cane 
  and 
  grasses, 
  whereas 
  the 
  very 
  similar 
  O. 
  

   chalybcits 
  is 
  distinctly 
  a 
  tree 
  species, 
  and 
  has 
  the 
  usual 
  carnivor- 
  

   ous 
  habits. 
  Specimens 
  of 
  a 
  very 
  fine 
  blue 
  lady-bird 
  were 
  found 
  

   feeding 
  on 
  Diaspines 
  on 
  Pandamis; 
  seemingly 
  a 
  valuable 
  species 
  to 
  

   introduce, 
  thev 
  died 
  out 
  in 
  course 
  of 
  transit. 
  Buth 
  the 
  Coccinel- 
  

   lid 
  and 
  Scale 
  are 
  comparatively 
  rare. 
  A 
  black 
  lady-bird 
  of 
  about 
  

   the 
  same 
  size 
  and 
  shape 
  was 
  also 
  observed, 
  while 
  a 
  small 
  patch 
  

   of 
  forest 
  close 
  to 
  a 
  cane 
  field 
  was 
  examined 
  and 
  some 
  good 
  lady- 
  

   birds 
  were 
  found 
  there. 
  xA-n 
  ant 
  {Phcidolc), 
  which 
  is 
  our 
  com- 
  

   mon 
  species 
  in 
  Hawaii, 
  swarmed 
  everywhere, 
  and 
  no 
  lady-bird 
  

   or 
  its 
  larva 
  could 
  get 
  at 
  the 
  scales 
  on 
  many 
  badly 
  affected 
  trees.
