  I 
  can 
  add 
  but 
  a 
  few 
  generalizations 
  on 
  the 
  life-cycle 
  of 
  the 
  

   weevil. 
  Larvae 
  were 
  found 
  in 
  various 
  stages 
  of 
  development 
  

   up 
  to 
  June 
  27th, 
  when 
  the 
  first 
  pupae 
  were 
  observed 
  within 
  in- 
  

   fested 
  seeds. 
  On 
  July 
  3rd 
  the 
  first 
  adult 
  weevil 
  to 
  be 
  seen 
  of 
  

   this 
  year's 
  brood 
  was 
  taken 
  from 
  the 
  seeds 
  of 
  mangoes 
  under 
  ob- 
  

   servation 
  in 
  the 
  laboratory. 
  To 
  summarize 
  — 
  the 
  adults 
  became 
  

   active 
  May 
  16th, 
  the 
  first 
  larva 
  was 
  found 
  May 
  28th, 
  the 
  pupae 
  

   appeared 
  June 
  27th, 
  and 
  the 
  adults 
  on 
  July 
  3rd. 
  In 
  a 
  very 
  gen- 
  

   eral 
  way 
  the 
  life 
  cycle 
  is 
  approximately 
  48 
  days. 
  I 
  am 
  inclined 
  

   to 
  think 
  there 
  is 
  but 
  one 
  brood 
  a 
  year. 
  

  

  This 
  paper 
  was 
  illustrated 
  by 
  specimens 
  and 
  photographs, 
  and 
  

   was 
  followed 
  by 
  general 
  discussion. 
  Mr. 
  O. 
  H. 
  Swezey 
  stated 
  

   that 
  of 
  thirty 
  mangoes 
  collected 
  at 
  Kalihi 
  he 
  found 
  only 
  three 
  

   free 
  from 
  infestation; 
  on 
  the 
  12th 
  of 
  June 
  he 
  observed 
  the 
  first 
  

   adults 
  in 
  mangoes 
  collected 
  at 
  the 
  same 
  place. 
  Mr. 
  F. 
  Muir 
  ex- 
  

   hibited 
  a 
  series 
  of 
  weevils 
  from 
  Fiji. 
  One 
  of 
  these 
  was 
  very 
  sim- 
  

   ilar 
  in 
  appearance 
  to 
  Cryptorhynchus 
  mangiferae 
  and 
  presumably 
  

   injured 
  mangoes 
  in 
  Fiji 
  in 
  a 
  similar 
  manner. 
  Of 
  two 
  sugar 
  cane 
  

   borers 
  one 
  was 
  recognized 
  as 
  identical 
  with 
  the 
  Hawaiian 
  species 
  

   (Sphenophoms 
  ohscurus) 
  while 
  the 
  other 
  was 
  entirely 
  different.

   The 
  nineteenth 
  regular 
  meeting 
  was 
  held 
  at 
  the 
  usual 
  place, 
  

   Mr. 
  G. 
  W. 
  Kirkaldy 
  in 
  the 
  chair. 
  

  

  Notes 
  and 
  Exhibitions 
  of 
  Specimens. 
  

   Mr. 
  D. 
  L. 
  Van 
  Dine 
  exhibited 
  specimens 
  of 
  Buprestis 
  aurii- 
  

   lenta 
  (Linn.) 
  collected 
  by 
  Mr. 
  H. 
  L. 
  Sturtevant, 
  Honokaa, 
  Hawaii, 
  

   on 
  January, 
  1906, 
  and 
  determined 
  by 
  Mr. 
  E. 
  A. 
  Schwarz. 
  It 
  is 
  

   common 
  along 
  the 
  Pacific 
  Coast 
  and 
  British 
  Columbia, 
  and 
  was 
  

   probably 
  introduced 
  into 
  Hawaii 
  in 
  Pine-lumber.
