  The 
  classification 
  of 
  the 
  Hemiptera 
  has, 
  in 
  the 
  past, 
  been 
  

   based 
  entirely 
  C) 
  upon 
  characters 
  afforded 
  by 
  the 
  imago, 
  so 
  

   that 
  it 
  is 
  not 
  surprising 
  that 
  the 
  Hemiptera 
  remain, 
  in 
  that 
  

   respect, 
  in 
  a 
  very 
  unsatisfactory 
  state. 
  

  

  The 
  Ontogeny 
  of 
  a 
  living 
  thttig 
  is 
  an 
  epitome 
  of 
  its 
  Phylo- 
  

   geny, 
  though 
  this 
  may 
  sometimes 
  be 
  partially 
  obscured, 
  among 
  

   Insects 
  perhaps 
  less 
  in 
  an 
  exopterygote, 
  paurometabolous 
  

   Homomorph, 
  as, 
  e. 
  g., 
  a 
  Hemipteron, 
  than 
  in 
  an 
  endopterygote 
  

   homometabolous 
  Heteromorph, 
  such 
  as 
  a 
  Lepidopteron 
  ( 
  ). 
  

   It 
  is 
  therefore 
  remarkable 
  that 
  the 
  usually 
  easily 
  reared 
  Hemip- 
  

   tera 
  have 
  been 
  neglected 
  in 
  this 
  wise 
  to 
  a 
  greater 
  extent 
  than 
  

   any 
  of 
  the 
  larger 
  Orders 
  of 
  Hexapoda 
  C), 
  neglected 
  so 
  greatly 
  

   that 
  a 
  biologic 
  note 
  on 
  any 
  Hemipteron 
  save 
  a 
  destructive 
  pest 
  

   is 
  a 
  matter 
  for 
  happy 
  surprise. 
  

  

  This 
  is 
  all 
  the 
  more 
  remarkable 
  when 
  it 
  is 
  considered 
  that 
  

   the 
  form 
  of 
  the 
  ova 
  and 
  the 
  manner 
  of 
  their 
  deposition 
  and 
  the 
  

   colours, 
  patterns 
  and 
  structures 
  of 
  the 
  nymphal 
  instars, 
  are 
  in 
  

   themselves 
  profoundly 
  interesting 
  and 
  that 
  they 
  also 
  yield 
  

   characters 
  of 
  generic 
  or 
  specific 
  value. 
  

  

  In 
  former 
  times, 
  the 
  adult 
  wingless 
  forms 
  of 
  certain 
  Hemip- 
  

   tera 
  were 
  rejected 
  as 
  being 
  immature 
  ; 
  of 
  recent 
  years, 
  nymphs 
  

   have 
  been 
  mistaken 
  for 
  adults 
  and 
  relied 
  upon 
  for 
  the 
  creation 
  

   of 
  genera 
  ! 
  for 
  example, 
  Budaeus 
  and 
  Critobulus 
  in 
  the 
  Geocor-

  (1) 
  Except 
  in 
  the 
  Sternorhynchous 
  Homoptera. 
  

  

  (2) 
  In 
  many 
  Diptera, 
  this 
  recapitulation 
  is 
  exceedingly 
  rapid, 
  and 
  

   probably 
  greatly 
  obscured.

  Easily 
  reared 
  under 
  sufficiently 
  natural 
  conditions, 
  but, 
  in 
  these 
  

   Islands, 
  it 
  is 
  almost 
  impossible 
  to 
  rear-up, 
  at 
  sea-level, 
  from 
  ova 
  or 
  

   young 
  nymphs, 
  bugs 
  and 
  hoppers 
  inhabiting 
  the 
  mountain 
  forests.
