  on 
  the 
  mountains 
  a 
  mile 
  or 
  two 
  behind 
  Tantalus, 
  the 
  climate 
  

   becomes 
  more 
  agreeable 
  to 
  the 
  Hawaiian 
  beetles 
  on 
  this 
  moun- 
  

   tain, 
  for 
  it 
  is 
  noteworthy 
  that 
  in 
  most 
  localities 
  with 
  excessive 
  

   precipitation 
  the 
  Coleopterous 
  fauna 
  is 
  scanty. 
  

  

  The 
  native 
  Longicorns 
  are 
  not 
  very 
  numerous 
  consisting 
  of 
  

   our 
  single 
  species 
  of 
  Parandra, 
  Aegosoma 
  refexum, 
  the 
  small 
  

   Clytarlus 
  jragilis 
  of 
  the 
  Koa, 
  and 
  several 
  Plagithmysus. 
  P. 
  

   solitarius 
  is 
  on 
  Eugenia 
  sandivichensis 
  and 
  is 
  not 
  rare. 
  More 
  

   rarely 
  it 
  breeds 
  in 
  Metrosiderus. 
  On 
  one 
  occasion 
  I 
  took 
  eighty 
  

   larvae 
  in 
  a 
  small 
  piece 
  of 
  wood 
  of 
  the 
  "Ohia-ha," 
  but 
  all 
  save 
  

   two 
  were 
  destroyed 
  by 
  Braconid 
  parasites, 
  and 
  the 
  elevation 
  

   being 
  only 
  about 
  1200 
  feet 
  ants 
  also 
  were 
  attacking 
  the 
  beetles. 
  

   P. 
  pulverulentus 
  and 
  cristatus 
  are 
  common 
  on 
  unhealthy 
  Koa 
  

   trees 
  and 
  as 
  these 
  unhealthy 
  trees, 
  owing 
  to 
  the 
  settlement 
  on 
  

   the 
  mountain, 
  are 
  now 
  abundant, 
  the 
  beetles 
  must 
  be 
  extremely 
  

   so. 
  Callithmysus 
  koehelei 
  in 
  shady 
  places 
  on 
  Pipturus, 
  and 
  C. 
  

   microgaster 
  on 
  Bobea 
  are 
  always 
  worth 
  looking 
  for. 
  I 
  have 
  taken 
  

   microgaster 
  in 
  May, 
  June 
  and 
  November, 
  koebelei 
  chiefly 
  in 
  the 
  

   latter 
  month. 
  The 
  larvae 
  of 
  microgaster 
  I 
  have 
  taken 
  in 
  numbers, 
  

   but 
  the 
  beetles 
  rarely 
  and 
  singly. 
  Of 
  the 
  weevils 
  the 
  fine 
  Otior- 
  

   hynchine, 
  Rhyncogonus 
  blackburni 
  is 
  found 
  sparsely 
  on 
  all 
  sorts 
  

   of 
  trees, 
  but 
  its 
  life 
  history 
  is 
  altogether 
  unknown. 
  The 
  hitherto 
  

   unique 
  R. 
  koebelei 
  was 
  found 
  near 
  by, 
  and 
  should 
  be 
  rediscovered. 
  

   The 
  Cryptorhynchines 
  are 
  represented 
  by 
  Acalles 
  duplex 
  and 
  at 
  

   least 
  three 
  or 
  four 
  other 
  species, 
  all 
  but 
  the 
  one 
  named 
  being 
  

   most 
  difficult 
  to 
  collect. 
  I 
  have 
  cut 
  some 
  of 
  them 
  out 
  of 
  very 
  

   hard 
  and 
  dry 
  dead 
  twigs 
  and 
  branches 
  of 
  different 
  forest 
  trees. 
  

   Dryophthorus 
  is 
  well 
  represented 
  by 
  squalidus, 
  distinguenduSy 
  

   gravidus, 
  crassus, 
  declivis, 
  modestus, 
  oahuensis, 
  insignis 
  and 
  

   insignoides; 
  ptisillus, 
  the 
  distinctness 
  of 
  which 
  from 
  modestus 
  

   seems 
  to 
  me 
  doubtful, 
  might 
  be 
  rediscovered 
  in 
  tree-ferns, 
  where 
  

   it 
  was 
  found 
  by 
  Blackburn. 
  The 
  Dryophthorus 
  are 
  gregarious 
  and 
  

   it 
  is 
  quite 
  usual 
  to 
  find 
  from 
  two 
  to 
  half 
  a 
  dozen 
  species 
  in 
  a 
  

   single 
  flock. 
  Pentarthrum 
  prolixum 
  is 
  abundant 
  on 
  tree-ferns, 
  and 
  

   obscurum 
  and 
  blackburni 
  are 
  both 
  to 
  be 
  found, 
  the 
  latter 
  at 
  very 
  

   low 
  elevations 
  or 
  even 
  on 
  the 
  plains. 
  Orothreptes 
  callithrix, 
  orig- 
  

   inally 
  described 
  from 
  Kona, 
  Hawaii, 
  is 
  not 
  rare 
  at 
  1500 
  feet 
  and 
  

   Deinocossonus 
  is 
  taken 
  singly 
  and 
  infrequently, 
  Pseudolus 
  (two 
  

   species) 
  and 
  Phloeophagosoma 
  are 
  in 
  decaying 
  Kukui, 
  Cactus 
  

   and 
  other 
  soft 
  woods, 
  while 
  an 
  undescribed 
  Nesotociis 
  is 
  very 
  rare.
