  gave 
  an 
  outline 
  of 
  his 
  recent 
  five 
  months' 
  trip 
  in 
  the 
  tropics, 
  on 
  a 
  

   survey 
  of 
  the 
  pink 
  boll 
  worm. 
  

  

  Dr. 
  Hooker 
  of 
  the 
  Experiment 
  Station 
  Record 
  spoke 
  on 
  the 
  subject 
  

   How 
  can 
  abstracts 
  in 
  the 
  Record 
  he 
  made 
  more 
  useful? 
  There 
  was 
  a 
  discussion 
  

   by 
  Messrs. 
  Hyslop, 
  Cushman, 
  Schwarz, 
  Rohwer 
  and 
  others. 
  

  

  Mr. 
  Caudell 
  exhibited 
  a 
  specimen 
  of 
  the 
  imported 
  Japanese 
  preying 
  man- 
  

   tid 
  Tenodera 
  sinensis 
  Sauss., 
  taken 
  in

  Mr. 
  Schwarz 
  exhibited 
  a 
  specimen 
  of 
  a 
  male 
  and 
  female 
  of 
  the 
  curious 
  

   Calandriid 
  beetle 
  Cyrtotrachelus 
  longimanus 
  Fabr. 
  from 
  Mt. 
  Omei, 
  Province 
  

   Tseschauan, 
  northeast

  Mr. 
  Sasscer 
  reported 
  the 
  interception 
  at 
  Baltimore, 
  Md., 
  by 
  Mr. 
  C. 
  E. 
  

   Prince, 
  an 
  Inspector 
  of 
  the 
  Federal 
  Horticultural 
  Board, 
  of 
  a 
  box 
  in 
  the 
  pos- 
  

   session 
  of 
  a 
  passenger 
  from 
  Brazil 
  containing 
  miscellaneous 
  tree 
  and 
  garden 
  

   seeds 
  and 
  fifty 
  odd 
  packages 
  of 
  cotton 
  and 
  cotton 
  lint. 
  The 
  cotton 
  seed 
  

   contained 
  living 
  adults, 
  pupae 
  and 
  larvae 
  of 
  the 
  Pink 
  Boll 
  worm. 
  He 
  also 
  

   exhibited 
  a 
  string 
  of 
  so-called 
  "Italian 
  Beads" 
  found 
  in 
  mail 
  at 
  San 
  Francisco. 
  

   The 
  so-called 
  beads 
  were 
  filberts 
  infested 
  with 
  larvae 
  of 
  Plodia 
  inter 
  punctella 
  

   Hbn. 
  

  

  C. 
  T. 
  Greene 
  exhibited 
  three 
  photographs 
  showing 
  the 
  adult 
  spider 
  

   parasite 
  fly 
  Oncodes 
  costatus 
  Loew, 
  and 
  its 
  eggs.

  The 
  348th 
  meeting 
  was 
  held 
  April

  1922, 
  at 
  the 
  New 
  National 
  Museum. 
  

   Vice-President 
  R.

  Cushman 
  presided 
  and 
  34

  present. 
  

  

  Notes 
  and 
  exhibition 
  of 
  specimens 
  

  

  Dr. 
  Howard 
  spoke 
  of 
  a 
  note 
  recently 
  published 
  by 
  Dr. 
  Feysand 
  regarding 
  

   the 
  Hymenopterous 
  parasite 
  Habrobracon 
  johannseni 
  Viereck 
  stinging 
  the 
  

   larva 
  of 
  the 
  potato 
  tuber 
  moth 
  Phthorimaea 
  opercullella 
  Zeller 
  after 
  it 
  had 
  

   spun 
  the 
  cocoon. 
  The 
  parasite 
  afterwards 
  feeds 
  through 
  the 
  oviposition 
  hole. 
  

  

  Mr. 
  Cushman 
  spoke 
  of 
  the 
  feeding 
  of 
  Calliephialtes, 
  parasite 
  of 
  the 
  codling 
  

   moth. 
  They 
  feed 
  at 
  the 
  punctures 
  made 
  by 
  the 
  ovipositor. 
  He 
  described 
  

   the 
  pumping 
  motion 
  employed 
  by 
  the 
  parasite 
  to 
  bring 
  the 
  juice 
  of 
  the 
  host 
  

   within 
  its 
  reach. 
  

  

  Dr. 
  Aldrich 
  said 
  that 
  several 
  species 
  of 
  Agromyza 
  puncture 
  the 
  leaf 
  with 
  

   the 
  ovipositor 
  and 
  suck 
  the 
  juice 
  for 
  nutriment. 
  

  

  Dr. 
  Howard 
  brought 
  up 
  the 
  matter 
  of 
  the 
  estimates 
  that 
  have 
  been 
  made 
  

   of 
  the 
  total 
  number 
  of 
  described 
  species 
  of 
  insects 
  and 
  of 
  the 
  total 
  number 
  

   of 
  species 
  that 
  exist 
  in 
  the 
  world. 
  A 
  general 
  discussion 
  followed. 
  

  

  Hymenoptera. 
  — 
  Mr. 
  RohwER 
  had 
  counted 
  sample 
  pages 
  of 
  Dalla 
  Torre's 
  

   catalogue 
  and 
  considered 
  it 
  would 
  be 
  conservative 
  to 
  consider 
  ten 
  valid 
  names 
  

   per 
  page 
  for 
  Dalla 
  Torre's 
  catalogue. 
  For 
  the 
  species 
  described 
  since 
  Dalla 
  

   Torre, 
  Mr. 
  RohwER 
  used 
  the 
  card 
  catalogue 
  in 
  the 
  National 
  Museum, 
  and 
  

   after 
  carefully 
  estimating 
  the 
  number 
  of 
  cards 
  he 
  subtracted 
  one-third 
  for 
  

   generic 
  transfers, 
  synonomy, 
  reference 
  to 
  biology, 
  etc. 
  After 
  completing 
  

   these 
  estimates 
  he 
  had 
  talked 
  to 
  some 
  of 
  his 
  colleagues 
  and 
  Mr. 
  Gahan 
  had 
  

   pointed 
  out 
  that 
  for 
  the 
  Chalcids 
  the 
  estimate 
  was, 
  in 
  his 
  opinion, 
  about 
  two 
  

   thousand 
  too 
  few. 
  To 
  prove 
  this 
  Mr. 
  Gahan 
  had 
  estimated 
  the 
  index 
  of 
  

   the 
  volume 
  of 
  the 
  Genera 
  Insectorum 
  and 
  found 
  it 
  contained 
  about 
  6500 
  spe- 
  

   cies. 
  It 
  must 
  be 
  remembered 
  that 
  this 
  volume 
  of 
  the 
  Genera 
  Insectorum 
  

   contains 
  but 
  very 
  little 
  synonomy 
  and 
  but 
  few 
  species 
  other 
  than 
  those 
  which 
  

   occur 
  in 
  Dalla 
  Torre's 
  catalogue. 
  Mr. 
  Gahan's 
  estimate 
  for 
  the 
  Chalcidoids
