  species 
  now 
  found 
  on 
  the 
  Islands, 
  but 
  it 
  mip^ht 
  be 
  the 
  C. 
  oceanic 
  a 
  

   of 
  Walker, 
  gathered 
  by 
  the 
  Beechey 
  expedition 
  three 
  quarters 
  of 
  

   a 
  century 
  ago. 
  If 
  not, 
  it 
  is 
  no 
  doubt 
  new, 
  and 
  in 
  any 
  case 
  interest- 
  

   ing. 
  The 
  Coleoptera 
  are 
  represented 
  by 
  the 
  two 
  Cossonidae 
  from 
  

   Midway, 
  the 
  first 
  being 
  identical 
  with 
  the 
  unique 
  specimen 
  from 
  

   Lanai 
  described 
  by 
  me 
  in 
  the 
  Fauna 
  Hawaiiensis 
  ; 
  the 
  second 
  is 
  

   a 
  commonplace 
  Pcntarthrum, 
  possibly 
  the 
  common 
  P. 
  obscuritm 
  

   of 
  these 
  Islands. 
  I 
  advised 
  Mr. 
  Wilder 
  not 
  to 
  collect 
  the 
  Dermes- 
  

   tids 
  found 
  in 
  dead 
  birds, 
  the 
  Sarcophagid 
  flies, 
  etc., 
  as 
  I 
  had 
  pre- 
  

   viously 
  seen 
  such 
  from 
  Laysan 
  and 
  they 
  were 
  of 
  little 
  interest, 
  

   though 
  most 
  abundant 
  there. 
  But 
  for 
  this 
  he 
  would 
  no 
  doubt 
  

   have 
  obtained 
  more 
  specimens 
  and 
  species 
  in 
  spite 
  of 
  the 
  limited 
  

   time. 
  

  

  Mr. 
  Perkins 
  further 
  exhibited 
  six 
  female 
  specimens 
  of 
  Redu- 
  

   I'iolus, 
  two 
  from 
  Oahu, 
  two 
  from 
  Molokai, 
  and 
  two 
  from 
  Hiwaii. 
  

   He 
  said 
  that 
  according 
  to 
  Mr. 
  Kirkaldy's 
  views 
  in 
  the 
  Fauna 
  

   Hawaiiensis 
  these 
  would 
  all 
  be 
  placed 
  under 
  R. 
  Ittsciosiis, 
  but 
  that 
  

   in 
  his 
  opinion 
  these 
  six 
  individuals 
  represented 
  four 
  distinct 
  spe- 
  

   cies, 
  since 
  they 
  exhibit 
  marked 
  differences 
  in 
  the 
  structure 
  of 
  th^ 
  

   terminal 
  segments. 
  It 
  was 
  observed 
  that 
  while 
  the 
  two 
  Oahu 
  

   examples 
  agreed 
  together 
  exactly, 
  as 
  also 
  did 
  the 
  two 
  from 
  Ivlolo- 
  

   kai, 
  the 
  two 
  from 
  Hawaii 
  were 
  not 
  alike, 
  and 
  were 
  also 
  unlike 
  

   those 
  from 
  Molokai 
  or 
  Oahu, 
  and 
  that 
  these 
  sexual 
  differences 
  

   were 
  accompanied 
  by 
  other 
  cuiite 
  evident 
  but 
  more 
  superficial 
  dis- 
  

   tinctions 
  in 
  each 
  case. 
  .^, 
  

  

  Mr. 
  Perkins 
  also 
  exhibited 
  two 
  specimens 
  and 
  drawings 
  of 
  a 
  

   Chalcid 
  parasite, 
  and 
  its 
  host, 
  an 
  Australian 
  Jassid 
  leaf-hopper, 
  

   being 
  one 
  of 
  the 
  two 
  species 
  of 
  Chalcids 
  known 
  to 
  be 
  parasitic 
  on 
  

   nymph 
  or 
  adult 
  hoppers. 
  The 
  form 
  exhibited 
  represents 
  a 
  new 
  

   genus 
  and 
  species, 
  which 
  he 
  proposed 
  to 
  describe 
  as 
  Neocladia 
  

   hoivardi. 
  

  

  DECEMBER 
  7th, 
  1905. 
  

  

  No 
  regular 
  meeting 
  was 
  held 
  on 
  this 
  date, 
  owing 
  to 
  the 
  lack 
  

   of 
  a 
  quorum.
