  sented 
  with 
  at 
  least 
  eight 
  species 
  of 
  Delphacidae, 
  four 
  or 
  five 
  

   Olianis, 
  and 
  a 
  common 
  lolania. 
  Compared 
  with 
  the 
  orders 
  

   already 
  dealt 
  with, 
  however, 
  the 
  Rhynchota 
  are 
  very 
  common- 
  

   place 
  and 
  poorly 
  represented. 
  

  

  HETEROPTERA. 
  

  

  Lasiochihts 
  denigratus 
  is, 
  so 
  far 
  as 
  I 
  remember, 
  not 
  abundant, 
  

   and 
  is 
  probably 
  the 
  only 
  truly 
  endemic 
  Anthocorid 
  on 
  Tantalus. 
  

   Orthotylus 
  of 
  the 
  Capsidae 
  yields 
  five 
  or 
  six 
  species, 
  and 
  there 
  are 
  

   probably 
  more. 
  The 
  one 
  described 
  Kamehameha 
  is 
  scarce 
  but 
  

   there 
  is 
  a 
  second 
  species 
  or 
  very 
  distinct 
  variety 
  of 
  this. 
  Koanoa 
  

   is 
  sometimes 
  common. 
  Nesidiorchestes 
  is 
  abundant, 
  but 
  tedious 
  

   to 
  collect 
  in 
  numbers. 
  Pseudoclerada 
  moral 
  is 
  not 
  common 
  but 
  

   is 
  nearly 
  always 
  obtainable. 
  Oronomiris 
  is 
  abundant 
  on 
  grass 
  

   at 
  all 
  elevations. 
  Acanthia 
  oakuensis 
  is 
  found 
  amongst 
  wet 
  

   leaves 
  and 
  on 
  bare 
  ground 
  while 
  some 
  species 
  of 
  Ploiariodes 
  are 
  

   common 
  and 
  there 
  is 
  a 
  Nesidiorchestes. 
  Of 
  Reduviolus, 
  blackburni, 
  

   subrufus, 
  rubritinctiis 
  and 
  lusciosus, 
  the 
  latter 
  as 
  defined 
  in 
  the 
  

   Fauna 
  Hawaiiensis, 
  embracing 
  at 
  least 
  three 
  distinct 
  species 
  

   from 
  Tantalus. 
  A 
  Sephora, 
  probably 
  calvus, 
  is 
  terrestrial 
  and 
  

   three 
  or 
  four 
  Nysius 
  are 
  more 
  or 
  less 
  common. 
  Three 
  species 
  of 
  

   Metrarga 
  occur 
  together, 
  M. 
  nuda 
  is 
  commonest 
  and 
  is 
  both 
  

   arboreal 
  and 
  terrestrial, 
  contracta 
  and 
  villosa 
  are 
  generally, 
  if 
  not 
  

   always, 
  terrestrial, 
  amongst 
  decaying 
  vegetation. 
  I 
  once 
  took 
  

   all 
  three 
  species 
  on 
  one 
  day, 
  on 
  a 
  certain 
  ridge. 
  Oechalia 
  grisea 
  

   is 
  periodically 
  abundant, 
  Coleotichus 
  less 
  common, 
  but 
  not 
  rare, 
  

   and 
  frequents 
  ferns 
  and 
  Koa 
  trees. 
  

  

  DIPTERA. 
  

  

  The 
  Dip 
  tera' 
  have 
  been 
  studied 
  least 
  of 
  aU 
  Hawaiian 
  insects 
  

   and 
  no 
  doubt 
  many 
  new 
  species 
  can 
  be 
  taken 
  on 
  Tantalus, 
  or 
  in 
  

   any 
  other 
  mountain 
  locality. 
  The 
  rather 
  fine 
  Sarcophagid 
  flies 
  

   of 
  the 
  genus 
  Prosthetochaeta 
  and 
  Dyscritomyia 
  occur 
  but 
  only 
  one 
  

   or 
  two 
  species 
  of 
  either. 
  Somewhat 
  resembling 
  flesh-flies 
  of 
  the 
  

   genus 
  Lucilia, 
  they 
  are 
  by 
  far 
  the 
  finest 
  Hawaiian 
  Diptera, 
  but 
  in 
  

   other 
  countries 
  would 
  attract 
  little 
  attention. 
  The 
  small 
  flight- 
  

   less 
  Dolichopodid 
  of 
  the 
  genus 
  Eniperoptera 
  is 
  locally 
  common. 
  

   Of 
  Pipunculus 
  there 
  are 
  at 
  least 
  three 
  species, 
  parasitic 
  on 
  leaf- 
  

   hoppers. 
  The 
  species 
  of 
  Drosophila, 
  of 
  which 
  several 
  are 
  known 
  

   breeding 
  in 
  banana 
  stems, 
  Pisonia 
  and 
  other 
  trees,
