  from 
  eggs 
  laid 
  in 
  the 
  larvae 
  of 
  the 
  Horn-fly 
  ( 
  Haematobia 
  serrata) 
  . 
  

   They 
  were 
  bred 
  from 
  eggs 
  laid 
  by 
  a 
  female 
  confined 
  with 
  200 
  

   maggots 
  in 
  a 
  jar 
  about 
  a 
  month 
  previously. 
  In 
  all, 
  29 
  females 
  

   and 
  6 
  males 
  issued 
  from 
  these 
  larvae. 
  As 
  these 
  numbers 
  do 
  not 
  

   represent 
  an 
  average, 
  it 
  is 
  not 
  certain 
  that 
  they 
  are 
  normal. 
  

   The 
  metamorphoses 
  of 
  Stomoxys 
  consumed 
  about 
  14 
  days, 
  those 
  

   of 
  Haematobia 
  close 
  on 
  to 
  three 
  weeks; 
  the 
  larvae 
  of 
  the 
  latter 
  

   were 
  more 
  numerous 
  in 
  cow 
  dung 
  five 
  or 
  six 
  days 
  old 
  than 
  that 
  

   three 
  or 
  four 
  days 
  old. 
  In 
  the 
  latter 
  those 
  of 
  the 
  larger 
  flies 
  

   were 
  more 
  abundant.

  A 
  Note 
  On 
  The 
  Immigpation 
  of 
  Hemiptera 
  Into 
  Oceanic 
  

  

  Islands.

  The 
  geographical 
  distribution 
  of 
  Insects 
  is 
  now 
  so 
  greatly 
  

   vitiated 
  by 
  interisland 
  and 
  intercontinental 
  commerce, 
  that 
  the 
  

   smallest 
  record 
  of 
  immigration, 
  showing 
  whether 
  it 
  is 
  natural 
  or 
  

   artificial, 
  is 
  of 
  value. 
  

  

  At 
  a 
  recent 
  meeting 
  of 
  this 
  Society, 
  exhibition 
  was 
  made 
  of 
  a 
  

   Hemipteron, 
  Piezodorus 
  rubrofasciatiis 
  (Fabr.). 
  This 
  Cimicid 
  

   has 
  a 
  very 
  wide 
  distribution, 
  occurring 
  in 
  northern 
  Australia, 
  

   New 
  Caledonia, 
  Murua, 
  Lifu, 
  Fiji, 
  Tahiti, 
  Japan, 
  the 
  Philip- 
  

   pines, 
  Cochin 
  China, 
  India, 
  Sumatra, 
  Java, 
  Abyssinia 
  and 
  Zanzi- 
  

   bar, 
  that 
  is 
  to 
  say, 
  it 
  may 
  be 
  expected 
  almost 
  anywhere 
  in 
  the 
  

   Australasian, 
  Oriental 
  or 
  Ethiopian 
  Regions, 
  as 
  well 
  as 
  in 
  the 
  

   Manchurian 
  Subregion. 
  It 
  has 
  not 
  established 
  itself 
  in 
  the 
  

   Hawaiian 
  Islands, 
  at 
  least 
  it 
  has 
  not 
  yet 
  been 
  found, 
  but 
  it 
  is 
  

   very 
  interesting 
  to 
  hear 
  that 
  an 
  example 
  was 
  detected 
  and 
  killed 
  

   by 
  Mr. 
  Craw, 
  while 
  inspecting 
  introduced 
  plants, 
  at 
  the 
  Port 
  of 
  

   Honolulu. 
  It 
  is 
  pretty 
  certain 
  that 
  Piezodorus 
  rubrofasciatiis 
  

   would 
  have 
  become 
  established 
  here 
  sooner 
  or 
  later, 
  if 
  systematic 
  

   plant-inspection 
  had 
  not 
  been 
  enforced.
