  tropical 
  character. 
  Both 
  seem 
  to 
  be 
  particularly 
  hardy, 
  and 
  are 
  

   ruthlessly 
  and 
  relentlessly 
  destroyed 
  by 
  the 
  people. 
  They 
  ring- 
  

   bark 
  and 
  burn 
  everything 
  to 
  provide 
  a 
  miserably 
  poor 
  pasture 
  

   land. 
  In 
  some 
  places 
  acres 
  and 
  acres 
  of 
  valuable 
  trees 
  have 
  been 
  

   destroyed 
  and 
  the 
  land 
  allowed 
  to 
  become 
  covered 
  with 
  injurious 
  

   weeds, 
  so 
  that 
  it 
  is 
  absolutely 
  valueless 
  from 
  any 
  point 
  of 
  view, 
  

   yielding 
  neither 
  timber 
  nor 
  forage. 
  Many 
  of 
  the 
  Australian 
  

   woods 
  are 
  very 
  fine 
  for 
  building 
  and 
  other 
  purposes 
  ; 
  they 
  are 
  

   much 
  more 
  hardy 
  and 
  quick-growing 
  than 
  our 
  Hawaiian 
  trees, 
  

   and 
  many 
  could 
  be 
  no 
  doubt 
  imported 
  here 
  with 
  great 
  advantage.

  "Probably 
  all 
  these 
  are

  to 
  science

  In 
  reply 
  to 
  Mr. 
  Craw, 
  Mr. 
  Perkins 
  said 
  that 
  all 
  cane 
  insects 
  

   from 
  Queensland 
  should 
  be 
  kept 
  out. 
  They 
  have 
  moth-borers, 
  

   including 
  a 
  Nonagria, 
  which 
  is 
  parasitized, 
  however, 
  by 
  an 
  Eni- 
  

   cospilus. 
  There 
  are 
  at 
  least 
  twelve 
  species 
  of 
  leaf-hoppers 
  on 
  

   their 
  cane. 
  The 
  cane-hopper 
  of 
  Fiji 
  is 
  not 
  the 
  same 
  as 
  the 
  one 
  

   in 
  Australia 
  ; 
  it 
  has 
  a 
  Stylopid 
  parasite, 
  which 
  might 
  be 
  useful 
  

   here. 
  The 
  Australian 
  forests 
  did 
  not 
  seem 
  to 
  suffer 
  much 
  from 
  

   insect 
  injury, 
  when 
  in 
  their 
  natural 
  condition. 
  

  

  There 
  are 
  many 
  fruit-flies 
  of 
  the 
  genus 
  Dacus 
  in 
  Australia. 
  

   On 
  the 
  coast 
  steamers 
  the 
  larvae 
  and 
  pupae 
  were 
  seen 
  dropping 
  

   from 
  crates 
  of 
  bananas 
  and 
  tomatoes 
  in 
  dozens 
  on 
  the 
  deck. 
  They 
  

   do 
  much 
  damage 
  in 
  Queensland, 
  and 
  the 
  oranges 
  are 
  also 
  badly 
  

   infested. 
  

  

  Exhibitions. 
  

  

  Mr. 
  Kotinsky 
  exhibited 
  specimens 
  of 
  the 
  Elaterid, 
  Chalcolcpi- 
  

   dius 
  erythroloma, 
  44 
  specimens 
  of 
  which 
  were 
  collected 
  in 
  the 
  

   course 
  of 
  a 
  couple 
  of 
  months 
  by 
  Mr. 
  Giffard 
  on 
  one 
  Koa 
  tree
