  very

  Oligota, 
  one 
  or 
  two 
  Myllaena 
  all 
  rare, 
  and 
  an 
  occa- 
  

   sional 
  Diestota 
  are 
  all 
  I 
  have 
  noted. 
  Glyptoma 
  blackburni 
  and 
  

   the 
  much 
  rarer 
  Lispinodes 
  I 
  have 
  already 
  mentioned 
  under 
  

   ■Colydiidae. 
  The 
  Staphylinidae 
  of 
  Oahu 
  require 
  a 
  very 
  special 
  

   study 
  extending 
  over 
  several 
  years 
  to 
  get 
  together 
  a 
  fairly 
  good 
  

   collection. 
  

  

  The 
  Carabidae 
  are 
  well 
  represented 
  by 
  one 
  or 
  two 
  extremely 
  

   •common 
  and 
  some 
  very 
  scarce 
  species. 
  Chalcomenus 
  corruscMS 
  

   may 
  be 
  found 
  running 
  in 
  the 
  day 
  time 
  on 
  bare 
  ground 
  or 
  at 
  the 
  

   bottom 
  of 
  gulches. 
  It 
  is 
  interesting 
  as 
  being 
  the 
  first 
  known 
  

   Hawaiian 
  Carabid. 
  It 
  was 
  described 
  in 
  1834 
  or 
  half 
  a 
  century 
  

   before 
  any 
  other 
  species. 
  Colpocaccus 
  tantalus 
  is 
  very 
  common 
  

   in 
  many 
  situations 
  and 
  fifty 
  or 
  a 
  hundred 
  individuals 
  are 
  some- 
  

   times 
  found 
  in 
  a 
  single 
  batch. 
  Mesothriscus 
  muscicola 
  is 
  not 
  rare 
  

   .and 
  M. 
  prognathtis 
  probably 
  came 
  from 
  the 
  same 
  locality. 
  

   Metromenus 
  has 
  the 
  following 
  species; 
  palmae 
  common 
  on 
  

   Freycinctia; 
  mv.tahilis 
  in 
  stems 
  of 
  tree 
  ferns; 
  epicurus 
  abundant 
  

   and 
  very 
  variable 
  in 
  colour 
  and 
  structure; 
  fraternus 
  rare, 
  fossi- 
  

   pennis 
  local, 
  jugitivus 
  not 
  rare; 
  protervtis 
  very 
  rare; 
  cuneipennis 
  

   rather 
  common. 
  

  

  M. 
  cuneipennis 
  and 
  jugitivus 
  are 
  true 
  ground 
  species, 
  while 
  

   the 
  others 
  named 
  are 
  found 
  in 
  various 
  situations. 
  There 
  are 
  

   also 
  three 
  or 
  four 
  other 
  species, 
  which 
  have 
  not 
  been 
  accurately 
  

   determined 
  at 
  present. 
  Thriscothorax 
  brevis 
  is 
  not 
  rare 
  and 
  is 
  

   always 
  found 
  on 
  the 
  ground, 
  and 
  Metrothorax 
  simiolus 
  is 
  some- 
  

   times 
  with 
  it, 
  but 
  more 
  often 
  found 
  in 
  cavities 
  of 
  tree 
  ferns 
  or 
  

   rotting 
  wood. 
  Bembidium 
  teres 
  runs 
  on 
  the 
  ground 
  in 
  gulches 
  

   or 
  damp 
  places, 
  as 
  also 
  does 
  B. 
  pacijicum. 
  Though 
  abundant 
  

   elsewhere 
  in 
  the 
  islands, 
  neither 
  is 
  common 
  on 
  Tantalus. 
  Prob- 
  

   ably 
  many 
  other 
  Oahuan 
  Carabidae 
  remain 
  to 
  be 
  found 
  in 
  this 
  

   locality 
  and 
  the 
  unique 
  Deropristus 
  blaptoides, 
  the 
  finest 
  of 
  all 
  

   Hawaiian 
  Carabidae, 
  should 
  be 
  looked 
  for 
  under 
  stones, 
  and 
  the 
  

   green 
  metallic 
  species 
  of 
  Derobrosctts 
  and 
  Brosconymus 
  in 
  cavities 
  

   in 
  the 
  higher 
  branches 
  of 
  Koa 
  trees. 
  

  

  HEMIPTERA 
  HOMOPTERA. 
  

  

  Three 
  or 
  four 
  species 
  of 
  Psyllidae 
  are 
  found, 
  causing 
  gall-like 
  

   growths 
  on 
  the 
  leaves 
  of 
  Pelea 
  and 
  Metrosideros. 
  Those 
  with 
  

   pigmented 
  wings 
  are 
  always 
  rare 
  or 
  local 
  species. 
  There 
  are 
  

   some 
  four 
  species 
  of 
  Jassidae, 
  but 
  the 
  Fulgorids 
  are 
  better 
  repre-
