  specimens 
  of 
  a 
  lagre 
  red-brown 
  Julid 
  (Myriapod), 
  not 
  recorded 
  

   in 
  the 
  " 
  Fauna 
  Hawaiiensis, 
  " 
  and 
  a 
  recent 
  introduction. 
  

   Dr. 
  Perkins 
  made 
  the 
  following 
  three 
  exhibits 
  : 
  

  

  (1) 
  A 
  Jassid, 
  common 
  on 
  the 
  mountains 
  near 
  Honolulu, 
  of 
  a 
  

   pale 
  yellow 
  or 
  bone 
  colour, 
  is 
  remarkable 
  for 
  the 
  fact 
  that 
  the 
  

   male 
  has 
  a 
  pronounced 
  pattern 
  of 
  black 
  markings 
  while 
  the 
  female 
  

   is 
  unicolorous. 
  Rarely 
  the 
  male 
  is 
  like 
  the 
  female, 
  without 
  a 
  

   pattern. 
  Still 
  more 
  rarely 
  it 
  has 
  the 
  pattern 
  miuch 
  reduced; 
  the 
  

   female 
  on 
  the 
  other 
  hand 
  appears 
  very 
  rarely 
  indeed 
  to 
  have 
  

   black 
  markings. 
  Other 
  Hawaiian 
  Jassids 
  exhibit 
  a 
  similar 
  

   striking 
  sexual 
  dichromatism. 
  Elsewhere 
  the 
  phenomenon 
  seems 
  

   not 
  to 
  be 
  common, 
  as 
  I 
  can 
  only 
  recall 
  one 
  species 
  of 
  Jassid 
  

   amongst 
  our 
  large 
  Australian 
  material 
  that 
  exhibits 
  it, 
  the 
  very 
  

   abundant 
  green 
  Nephotettix 
  apicalis 
  (Motschulsky) 
  . 
  

  

  (2) 
  A 
  species 
  of 
  Reduviolus 
  (R. 
  rubritinctus 
  Kirkaldy, 
  but 
  

   probably 
  not 
  R. 
  rubritinctus 
  of 
  Blackburn) 
  is 
  as 
  is 
  well 
  known, 
  re- 
  

   markable 
  for 
  the 
  incrassate 
  basal 
  joint 
  of 
  the 
  antennae. 
  

   Recently 
  on 
  picking 
  up 
  a 
  specimen 
  on 
  Tantalus 
  I 
  noticed 
  with 
  

   the 
  naked 
  eye 
  a 
  peculiar 
  projection 
  on 
  the 
  head 
  and 
  on 
  examin- 
  

   ing 
  this 
  at 
  home 
  with 
  a 
  lens 
  I 
  saw 
  that 
  it 
  was 
  one 
  of 
  two 
  stout 
  

   blunt 
  spines, 
  there 
  being 
  one 
  of 
  these 
  on 
  each 
  side 
  of 
  the 
  head 
  

   in 
  front 
  of 
  the 
  insertion 
  of 
  the 
  antennae. 
  Blackburn 
  makes 
  no 
  

   mention 
  of 
  these 
  spines 
  in 
  his 
  long 
  description 
  of 
  the 
  unique 
  type, 
  

   and 
  as 
  his 
  example 
  was 
  from 
  Maui, 
  while 
  all 
  those 
  mentioned 
  in 
  

   the 
  "Fauna 
  Hawaiiensis" 
  were 
  from 
  Oahu, 
  it 
  is 
  probable 
  that 
  

   these 
  are 
  distinct. 
  There 
  is 
  no 
  such 
  structure 
  in 
  any 
  other 
  

   Hawaiian 
  Reduviolus 
  that 
  I 
  possess 
  here. 
  

  

  (3) 
  A 
  collection 
  of 
  over 
  fifty 
  species 
  of 
  bugs 
  recently 
  col- 
  

   lected 
  at 
  Kilauea, 
  Hawaii. 
  

  

  The 
  President 
  then 
  read 
  the 
  annual 
  address: 
  

  

  Insects 
  at 
  Kilauea, 
  Hawaii. 
  

  

  By 
  R. 
  C. 
  L. 
  Perkins, 
  D. 
  Sc. 
  

  

  In 
  last 
  year's 
  address 
  I 
  gave 
  an 
  account 
  of 
  the 
  insect 
  fauna 
  

   of 
  a 
  portion 
  of 
  the 
  main 
  mountain 
  range 
  of 
  Oahu, 
  to 
  illustrate 
  

   in 
  a 
  general 
  way 
  what 
  one 
  may 
  expect 
  to 
  find 
  in 
  a 
  reasonably 
  

   good 
  locality 
  on 
  the 
  leeward 
  side 
  of 
  the 
  less 
  lofty 
  mountains, 
  

   such 
  as 
  are 
  found 
  on 
  Oahu, 
  Kauai 
  and 
  Molokai. 
  Tonight 
  I 
  

   will 
  speak 
  of 
  the 
  insects 
  that 
  are 
  found 
  in 
  the 
  vicinity 
  of 
  the 
  crater
