  Before 
  taking 
  the 
  orders 
  of 
  Insects 
  seriatim 
  and 
  listing 
  the 
  

   species 
  found 
  on 
  Tantalus, 
  it 
  is 
  proper 
  to 
  say 
  that, 
  excepting 
  the 
  

   Aculeate 
  Hymenoptera 
  and 
  in 
  a 
  rather 
  less 
  degree 
  the 
  beetles, 
  

   no 
  serious 
  attempt 
  has 
  been 
  made 
  by 
  me 
  to 
  acquire 
  a 
  complete 
  

   collection 
  of 
  insects 
  frequenting 
  the 
  locality. 
  Practically 
  my 
  

   whole 
  collection 
  thence 
  was 
  obtained 
  incidentally 
  to 
  special 
  

   researches 
  on 
  the 
  variation 
  of 
  certain 
  species 
  of 
  Coleoptera 
  and 
  

   other 
  insects 
  and 
  on 
  the 
  habits 
  and 
  foodplants, 
  etc., 
  of 
  these. 
  

  

  I 
  will 
  first 
  take 
  the 
  species 
  of 
  Macrolepidoptera, 
  that 
  is 
  to 
  

   say, 
  the 
  butterflies 
  and 
  moths, 
  excepting 
  the 
  Tortricina, 
  Tineina 
  

   and 
  the 
  Pterophoridae, 
  which 
  three 
  groups 
  I 
  cannot 
  at 
  present 
  

   name. 
  The 
  species 
  here 
  listed 
  are 
  such 
  as 
  I 
  have 
  myself 
  met 
  

   with 
  on 
  the 
  slopes 
  of 
  Tantalus, 
  but 
  I 
  believe 
  that 
  nearly 
  all 
  the 
  

   species 
  of 
  Macrolepidoptera 
  known 
  on 
  Oahu 
  might 
  be 
  found 
  

   there, 
  either 
  regularly 
  or 
  as 
  stragglers, 
  since 
  the 
  larger 
  moths 
  are 
  

   not 
  usually 
  much 
  localized 
  in 
  their 
  range 
  on 
  the 
  island 
  they 
  

   inhabit. 
  Most 
  of 
  my 
  work 
  on 
  the 
  Lepidoptera 
  of 
  Oahu 
  has 
  

   been 
  done 
  in 
  the 
  mountains 
  behind 
  Waialua 
  and 
  to 
  a 
  less 
  degree 
  

   in 
  the 
  Waianae 
  Mountains. 
  

  

  Of 
  the 
  stout-bodied 
  night 
  flying 
  moths 
  of 
  the 
  family 
  Noc- 
  

   tuidae, 
  I 
  can 
  report 
  very 
  few, 
  but 
  others 
  are 
  certainly 
  to 
  be 
  

   found. 
  Leucania 
  euclidias, 
  a 
  species 
  remarkable 
  for 
  its 
  variation 
  

   in 
  colour, 
  is 
  of 
  course 
  found, 
  as 
  in 
  all 
  other 
  mountain 
  localities 
  

   throughout 
  the 
  islands, 
  and 
  is 
  well 
  worth 
  examining 
  in 
  numbers 
  

   for 
  the 
  more 
  beautiful 
  and 
  unusual 
  varieties. 
  Leucania 
  amhly- 
  

   casis 
  is 
  found 
  as 
  far 
  down 
  as 
  the 
  plains 
  and 
  could 
  no 
  doubt 
  be 
  

   taken 
  in 
  numbers 
  on 
  the 
  flowers 
  of 
  the 
  Ohia 
  at 
  night, 
  as 
  in 
  other 
  

   parts 
  of 
  the 
  islands. 
  It 
  is 
  hardly 
  distinguishable 
  from 
  the 
  moth 
  

   of 
  the 
  " 
  army-worm" 
  (L. 
  unipuncta) 
  . 
  Once 
  I 
  saw 
  it 
  in 
  countless 
  

   thousands 
  on 
  those 
  flowers, 
  but 
  mistaking 
  it 
  for 
  the 
  common 
  pest 
  

   I 
  took 
  only 
  a 
  few 
  examples. 
  Agrotis 
  dislocata 
  and 
  A. 
  crinigera, 
  

   the 
  produce 
  of 
  two 
  of 
  our 
  commoner 
  cut-worms, 
  are 
  naturally 
  

   present, 
  and 
  I 
  obtained 
  one 
  handsome 
  specimen 
  of 
  the 
  more 
  

   recently 
  described 
  A. 
  hephaestea. 
  Hypenodes 
  altivolans 
  is 
  com- 
  

   mon 
  and 
  worth 
  examining 
  for 
  its 
  remarkable 
  variations 
  in 
  

   colour; 
  it 
  comes 
  to 
  light 
  and 
  sugar, 
  just 
  as 
  the 
  very 
  similar 
  H. 
  

   costaestrigalis 
  does 
  in 
  England. 
  No 
  other 
  Hawaiian 
  Noctuids 
  

   visit 
  sugared 
  trees. 
  Nesamipiis 
  obsoleta, 
  an 
  extraordinarily 
  

   variable 
  species, 
  abounds, 
  Cosmophila 
  noctivolans, 
  also 
  variable, 
  

   is 
  worth 
  collecting 
  in 
  series, 
  with 
  the 
  allied 
  but 
  not 
  endemic
