  • 
  Dr. 
  R. 
  C. 
  L. 
  Perkins 
  exhibited 
  two 
  species 
  of 
  the 
  Coleop- 
  

   teron 
  Xylebonis, 
  a 
  male 
  and 
  female 
  of 
  each. 
  The 
  scooped-out 
  

   head 
  of 
  the 
  former 
  as 
  distinct 
  from 
  the 
  normal 
  head 
  of 
  the 
  lat- 
  

   ter 
  was 
  the 
  principal 
  feature 
  of 
  the 
  exhibit. 
  Dr. 
  Perkins 
  also 
  

   exhibited 
  six 
  species 
  of 
  Plagithmysus 
  and 
  one 
  of 
  Clytarlus, 
  col- 
  

   lected 
  at 
  the 
  Volcano 
  House. 
  One 
  species 
  of 
  the 
  former 
  was 
  

   undescribed 
  and 
  would 
  shortly 
  be 
  namicd 
  by 
  him 
  after 
  Mr. 
  

   Giffard. 
  He 
  also 
  exhibited 
  a 
  specimen 
  of 
  an 
  undescribed 
  species 
  

   of 
  Callithymsus, 
  taken 
  on 
  a 
  stump 
  of 
  Mamake 
  {Pipturus 
  albidus) 
  

   on 
  Mt. 
  Tantalus.

  On 
  a 
  Species 
  of 
  Proterhinus 
  from 
  Samoa 
  [Coleoptera], 
  

  

  By 
  R. 
  C. 
  L. 
  Perkins,

  Sc. 
  

  

  The 
  genus 
  Proterhinus, 
  constituting 
  the 
  family 
  Proterhinidae, 
  

   with 
  not 
  less 
  than 
  130 
  known 
  species 
  inhabitating 
  the 
  Hawaiian 
  

   group, 
  has 
  hitherto 
  been 
  recorded 
  only 
  from 
  these 
  islands. 
  I 
  am 
  

   now 
  able 
  to 
  describe 
  a 
  species 
  from 
  the 
  Samoan 
  group, 
  distant 
  

   from 
  the 
  Hawaiian 
  by 
  more 
  than 
  two 
  thousand 
  miles, 
  and 
  lying 
  

   directly 
  between 
  the 
  latter 
  and 
  New 
  Zealand. 
  If 
  will 
  be 
  remem- 
  

   bered 
  that 
  New 
  Zealand 
  is 
  the 
  home 
  of 
  one 
  of 
  the 
  two 
  species 
  of 
  

   Aglycyderes, 
  constituting 
  by 
  themselves 
  a 
  peculiar 
  family, 
  and 
  

   one 
  which 
  alone 
  amongst 
  the 
  Coleoptera 
  has 
  any 
  possible 
  affinity 
  

   to 
  the 
  Proterhinidae. 
  I 
  anticipate 
  that 
  when 
  the 
  islands 
  of 
  the 
  

   Southern 
  Pacific 
  are 
  thoroughly 
  investigated 
  by 
  skilled 
  collectors 
  

   of 
  Micro-coleoptera 
  that 
  other 
  forms 
  of 
  Proterhinidae 
  will 
  be 
  

   discovered, 
  and 
  possibly 
  some 
  that 
  will 
  more 
  nearly 
  connect 
  these 
  

   with 
  Aglycyderes. 
  The 
  Samoan 
  species 
  here 
  described 
  is 
  one 
  of 
  

   the 
  sm.allest 
  in 
  the 
  genus, 
  and 
  superficially 
  (in 
  form 
  colour 
  and 
  

   clothing) 
  quite 
  resembles 
  some 
  of 
  the 
  more 
  commonplace 
  Hawaii- 
  

   an 
  forms, 
  so 
  far 
  as 
  the 
  $ 
  sex 
  (which 
  alone 
  is 
  known 
  to 
  me) 
  is 
  con- 
  

   cerned. 
  The 
  single 
  example 
  was 
  bred 
  from 
  the 
  woody 
  drupe 
  or 
  

   the 
  stem 
  of 
  attachment 
  of 
  a 
  cocoanut, 
  imported 
  as 
  seed 
  from 
  

   Samoa. 
  No 
  species 
  of 
  Proterhinus 
  is 
  known 
  to 
  affect 
  the 
  cocoa- 
  

   nut 
  in 
  the 
  Hawaiian 
  islands, 
  nor 
  indeed 
  is 
  any 
  native 
  wood-eating 
  

   beetle 
  to 
  be 
  found 
  on 
  the 
  lowlands 
  here, 
  all 
  such 
  having 
  been 
  

   exterminated 
  by 
  certain 
  foreign 
  ants 
  within 
  the 
  range 
  of 
  which 
  

   they 
  cannot 
  exist.
