  been 
  more 
  assiduously 
  collected, 
  and 
  of 
  the 
  latter 
  class 
  probably 
  

   not 
  many 
  additions 
  are 
  to 
  be 
  expected. 
  

  

  Of 
  the 
  Fossores 
  Nesomimesa 
  antennata, 
  preying 
  on 
  daddy- 
  

   long-legs 
  of 
  the 
  subfam. 
  Limnobiinae, 
  is 
  very 
  common, 
  and 
  was 
  

   collected 
  nearly 
  a 
  century 
  ago 
  by 
  the 
  early 
  explorers. 
  A 
  species 
  

   of 
  Deinomimesa 
  should 
  occur, 
  since 
  on 
  the 
  other 
  islands 
  the 
  two 
  

   genera 
  are 
  found 
  together. 
  Crabro 
  tmnidoventris 
  , 
  monticola, 
  

   tmicolor, 
  and 
  notostictus 
  are 
  all 
  present, 
  and 
  the 
  three 
  latter 
  are 
  

   more 
  noticeable 
  amongst 
  the 
  guava 
  scrub 
  of 
  the 
  lower 
  ridges. 
  

   The 
  very 
  rare 
  and 
  singular 
  Crabro 
  abnormis 
  should 
  be 
  looked 
  for. 
  

   I 
  have 
  found 
  it 
  at 
  elevations 
  of 
  about 
  1500 
  feet 
  elsewhere, 
  but 
  

   not 
  on 
  Tantalus, 
  though 
  Blackburn's 
  type 
  was 
  taken 
  hard 
  by. 
  

  

  Nesocrabro 
  stygius 
  flies 
  on 
  the 
  higher 
  ridges, 
  that 
  are 
  covered 
  

   with 
  "leie," 
  and 
  preys 
  on 
  the 
  metallic 
  green 
  flies 
  of 
  the 
  genus 
  

   Dyscritomyia 
  and 
  Prosthetochaeta. 
  

  

  Fourteen 
  species 
  of 
  Odynerus 
  have 
  been 
  found, 
  including 
  four 
  

   of 
  the 
  rarest 
  species. 
  Three 
  of 
  these, 
  0. 
  leiodemas, 
  eucharis, 
  and 
  

   homoeophanes 
  are 
  red 
  and 
  black 
  species, 
  and 
  fly 
  in 
  company 
  with 
  

   three 
  similarly 
  coloured 
  but 
  common 
  species— 
  O. 
  pseudochromus 
  , 
  

   0. 
  pseudochromoides, 
  and 
  0. 
  oahuensis. 
  I 
  always 
  keep 
  a 
  special 
  

   lookout 
  for 
  these 
  rare 
  species 
  and 
  usually 
  take 
  a 
  specimen 
  of 
  

   one 
  or 
  more 
  of 
  them 
  on 
  each 
  of 
  my 
  visits 
  to 
  Tantalus. 
  The 
  other 
  

   choice 
  species 
  isO. 
  illudens, 
  a 
  black 
  species, 
  which 
  exactly 
  resem- 
  

   bles 
  0. 
  montamis 
  and 
  other 
  common 
  species 
  superficially, 
  and 
  

   flies 
  with 
  these. 
  0. 
  unicus, 
  rudolphi, 
  montanus, 
  and 
  nigripennis 
  

   are 
  generally 
  distributed, 
  whilst 
  threnodes, 
  oblitus, 
  and 
  dubiosus 
  

   are 
  more 
  abundant 
  on 
  the 
  lowest 
  slopes 
  and 
  plains. 
  

  

  The 
  bees 
  of 
  the 
  genus 
  Nesoprosopis 
  are 
  facilis, 
  difficilis, 
  

   anthracina, 
  koae, 
  fuscipennis, 
  the 
  parasitic 
  volatilis, 
  and 
  the 
  rare 
  

   and 
  remarkable 
  anomala. 
  The 
  latter, 
  one 
  of 
  the 
  finest 
  and 
  most 
  

   interesting 
  of 
  the 
  native 
  bees, 
  I 
  have 
  taken 
  in 
  the 
  forest 
  of 
  intro- 
  

   duced 
  trees, 
  and 
  once 
  I 
  saw 
  it 
  on 
  Tantalus 
  itself. 
  It 
  is 
  a 
  very 
  

   desirable 
  insect. 
  The 
  single 
  native 
  ant 
  P 
  oner 
  a 
  perkinsi, 
  is 
  found 
  

   in 
  shady 
  or 
  damp 
  places 
  and 
  is 
  common. 
  Its 
  communities 
  

   consist 
  rarely 
  of 
  more 
  than 
  a 
  dozen 
  individuals. 
  

  

  The 
  parasitic 
  Hymenoptera 
  are 
  very 
  imperfectly 
  known. 
  

   There 
  are 
  two 
  species 
  of 
  Scleroderma, 
  and 
  three 
  of 
  Sierola 
  at 
  least, 
  

   amongst 
  the 
  Bethylidae. 
  They 
  are 
  no 
  doubt 
  parasitic 
  on 
  Cis 
  

   and 
  possibly 
  other 
  small 
  beetles, 
  and 
  they 
  may 
  frequently 
  be 
  

   bred 
  from 
  deadwood 
  infested 
  by 
  these.
