  Eucnemids 
  are 
  less 
  numerous, 
  the 
  large 
  black 
  Fornax 
  on 
  Koa 
  

   trees 
  being 
  the 
  most 
  conspicuous 
  and 
  alwaj'S 
  attainable. 
  V/ith 
  

   it 
  the 
  large 
  Cistelid 
  Labetes 
  hawaiiensis 
  is 
  also 
  always 
  to 
  be 
  found. 
  

  

  Of 
  weevils 
  Acalles 
  lateralis, 
  callichroma, 
  melanolepis, 
  ttiber- 
  

   culatus, 
  and 
  one 
  or 
  more 
  undescribed 
  species 
  are 
  all 
  rare. 
  None 
  

   have 
  been 
  collected 
  in 
  Olaa, 
  where 
  other 
  species 
  must 
  occur. 
  

   Drvophthorus 
  squalidus, 
  distingMenchis 
  , 
  and 
  peles 
  are 
  the 
  common 
  

   Kilauea 
  species; 
  gravidus, 
  declivis, 
  modestus 
  and 
  insignis 
  are 
  

   found 
  at 
  lower 
  elevations, 
  though 
  I 
  have 
  not 
  noted 
  them 
  from 
  

   Kilauea, 
  nor 
  should 
  I 
  have 
  taken 
  these 
  common 
  insects, 
  had 
  I 
  

   seen 
  them. 
  Pentarthrum 
  prolixum 
  is 
  abundant, 
  and 
  often 
  very 
  

   large; 
  Deinocossomis 
  nesiotes 
  rare, 
  Nesotocus 
  munroi 
  always 
  at- 
  

   tainable 
  both 
  at 
  Kilauea 
  and 
  in 
  Olaa. 
  Oodemas 
  requires 
  special 
  

   study, 
  individuals 
  being 
  very 
  abundant, 
  but 
  the 
  species 
  are 
  as 
  

   yet 
  yery 
  imperfectly 
  known, 
  being 
  excessively 
  difficult 
  to 
  deter- 
  

   mine. 
  Of 
  the 
  Scolytids 
  several 
  species 
  of 
  Xyleborus 
  are 
  found, 
  

   and 
  others 
  again 
  towards 
  Hilo. 
  It 
  is 
  especially 
  desirable 
  to 
  

   obtain 
  the 
  rare 
  males 
  and 
  associate 
  them 
  with 
  their 
  females, 
  to 
  

   which 
  they 
  bear 
  no 
  superficial 
  resemblance. 
  On 
  my 
  last 
  visit 
  

   I 
  was 
  able 
  to 
  take 
  the 
  sexes 
  of 
  two 
  species 
  in 
  company. 
  

  

  The 
  Longicorns 
  of 
  the 
  genus 
  Plagithmysus 
  and 
  Clytarlus 
  are 
  

   better 
  represented 
  than 
  in 
  any 
  other 
  locality 
  in 
  the 
  islands. 
  No 
  

   less 
  than 
  a 
  dozen 
  species 
  are 
  to 
  be 
  found 
  in 
  the 
  limits 
  of 
  a 
  little 
  

   over 
  two 
  miles 
  of 
  country, 
  and 
  a 
  visit 
  to 
  Olaa 
  may 
  yield 
  one 
  or 
  

   two 
  other 
  species. 
  I 
  discovered 
  a 
  new* 
  Plagithmysus 
  recently 
  

   about 
  half 
  a 
  mile 
  from 
  the 
  Hotel, 
  near 
  the 
  vegetable 
  garden. 
  The 
  

   species 
  are 
  P. 
  vitiicollis 
  (Kau 
  side), 
  P. 
  longulus 
  (Hilo 
  side), 
  P. 
  

   bishopi, 
  P. 
  bilineatus, 
  P. 
  perkinsi, 
  P. 
  varians, 
  P. 
  darwinianus, 
  

   P. 
  lamarckianus, 
  P. 
  sulpMrescens, 
  P. 
  giffardi 
  and 
  P. 
  gracilis 
  

   (which 
  I 
  believe 
  is 
  distinct 
  from 
  P. 
  bishopi). 
  Also 
  Clytarlus 
  

   filipes, 
  C. 
  claviger, 
  and 
  in 
  Olaa 
  C. 
  abnorniis. 
  

  

  Parandra 
  puncticeps 
  and 
  Aegosoma 
  reflexum 
  are 
  both 
  common. 
  

  

  HYMENOPTER.\. 
  

  

  About 
  fifty 
  bees 
  and 
  wasps 
  are 
  here 
  named, 
  mostly 
  from 
  the 
  

   immediate 
  neighborhood 
  of 
  the 
  volcano, 
  but 
  I 
  have 
  added 
  a 
  few 
  

   that 
  are 
  easily 
  obtained 
  in 
  Olaa 
  or 
  near 
  Hilo. 
  It 
  will 
  be 
  seen 
  

  

  *P. 
  giffardi 
  sp. 
  no 
  v. 
  very 
  closely 
  allied 
  to 
  P. 
  sulphurescens 
  Sh., 
  but 
  at 
  

   once 
  distinguished 
  bv 
  the 
  entire 
  absence 
  of 
  a 
  basal 
  fulvous 
  or 
  rufescent 
  

   area 
  on 
  the 
  elvtra. 
  It 
  is 
  attached 
  to 
  a 
  species 
  of 
  Myrsine.
