  W. 
  B. 
  Wood 
  told 
  of 
  the 
  finding 
  at 
  the 
  inspection 
  house 
  of 
  a 
  living 
  larva 
  of 
  

   the 
  pink 
  boll 
  worm 
  in 
  wild 
  cotton 
  from 
  India. 
  This 
  cotton 
  has 
  small 
  seeds 
  

   and 
  the 
  larva 
  was 
  working 
  from 
  the 
  outside. 
  Mr. 
  Barber 
  stated 
  that 
  the 
  

   insect 
  feeds 
  in 
  the 
  same 
  way 
  on 
  okra 
  seed. 
  

  

  Dr. 
  Howard 
  told 
  of 
  the 
  death 
  by 
  suicide 
  of 
  the 
  Russian 
  Entomologist 
  

  

  KjURDUMOV. 
  

  

  S. 
  A. 
  RoHWER 
  spoke 
  of 
  a 
  paper 
  by 
  Prof. 
  CockerEll 
  on 
  the 
  Bees 
  of 
  Ma- 
  

   deira. 
  Madeira 
  originally 
  had 
  no 
  bee 
  fauna 
  and 
  all 
  the 
  present 
  species 
  are 
  

   related 
  to 
  the 
  Palearctic 
  forms.

  J. 
  M. 
  Aldrich: 
  Collecting 
  in 
  Alaska. 
  

  

  Dr. 
  Aldrich 
  gave 
  an 
  account, 
  illustrated 
  by 
  lantern 
  slides, 
  of 
  his 
  summer's 
  

   collecting 
  in 
  Alaska, 
  during 
  which 
  he 
  traversed 
  the 
  entire 
  length 
  of 
  the 
  gov- 
  

   ernment 
  railway. 
  He 
  also 
  described 
  the 
  differences 
  in 
  climate, 
  topography 
  

   and 
  flora 
  of 
  the 
  various 
  parts 
  of 
  the 
  road, 
  and 
  mentioned 
  some 
  of 
  the 
  more 
  in- 
  

   teresting 
  insects, 
  especially 
  Diptera, 
  that 
  he 
  captured. 
  He 
  commented 
  es- 
  

   pecially 
  upon 
  the 
  great 
  abundance 
  of 
  mosquitoes 
  and 
  the 
  apparent 
  absence 
  

   of 
  the 
  house 
  fly. 
  

  

  Notes 
  and 
  exhibition 
  of 
  specimens 
  

  

  Dr. 
  J. 
  M. 
  Aldrich 
  exhibited 
  photographs 
  of 
  two 
  series 
  of 
  exuvia 
  of 
  larvae 
  

   of 
  the 
  museum 
  pest, 
  Trogoderma 
  iarsale, 
  one 
  showing 
  the 
  decrease 
  in 
  size 
  from 
  

   instar 
  to 
  instar 
  in 
  starved 
  larvae, 
  and 
  the 
  other 
  showing 
  the 
  successive 
  in- 
  

   stars 
  of 
  a 
  single 
  larva 
  that 
  had 
  been 
  alternately 
  starved 
  and 
  fed 
  for 
  nine 
  years 
  

   During 
  this 
  period 
  it 
  had 
  three 
  times 
  attained 
  maximum 
  size 
  and 
  twice 
  de- 
  

   creased 
  practically 
  to 
  first 
  instar 
  size. 
  

  

  A. 
  N. 
  Caudell 
  read 
  a 
  note 
  from 
  his 
  entomological 
  journal 
  recording 
  his 
  

   observations 
  on 
  a 
  specimen 
  of 
  the 
  psammocharid 
  wasp, 
  Anoplius 
  illinoiensis 
  

   Robertson. 
  This 
  wasp 
  was 
  apparently 
  bathing, 
  during 
  the 
  operation 
  de- 
  

   scending 
  into 
  the 
  water 
  to 
  the 
  depth 
  of 
  three 
  inches 
  and 
  walking 
  on 
  the 
  bottom. 
  

  

  R. 
  A. 
  St. 
  George 
  gave 
  some 
  phenological 
  records 
  on 
  cerambycids 
  in 
  com- 
  

   parison 
  with 
  plant 
  events 
  in 
  1921. 
  The 
  season 
  in 
  this 
  respect 
  was 
  as 
  a 
  whole 
  

   abnormal, 
  but 
  especially 
  in 
  two 
  species, 
  Neoclytus 
  erythrocephalus 
  and 
  Xylo- 
  

   trechus 
  colonus, 
  each 
  of 
  which 
  passed 
  through 
  two 
  generations 
  instead 
  of 
  the 
  

   normal 
  one 
  generation. 
  

  

  Dr. 
  A. 
  L. 
  Quaintance 
  exhibited 
  apples 
  from 
  Wenatchee, 
  Washington, 
  

   injured 
  by 
  the 
  pear 
  leaf 
  blister 
  mite. 
  

  

  A. 
  B. 
  Gahan 
  spoke 
  of 
  having 
  recently 
  received 
  a 
  specimen 
  of 
  Pac/z^^cr^- 
  

   poideus 
  dubius 
  Ashm., 
  a 
  chalcid 
  parasite 
  of 
  diptera, 
  reared 
  from 
  the 
  cheese 
  

   skipper, 
  Piophila 
  casei. 
  This 
  is 
  the 
  first 
  record 
  of 
  a 
  parasite 
  of 
  this 
  species 
  

   of 
  which 
  he 
  had 
  heard. 
  

  

  J. 
  C. 
  Bridwell 
  exhibited 
  living 
  specimens 
  of 
  the 
  Bethylid, 
  Sclerodermus 
  

   macrogastcr, 
  and 
  briefly 
  outlined 
  the 
  habits 
  of 
  members 
  of 
  the 
  genus, 
  which 
  

   live 
  gregariously 
  on 
  insect 
  larvae, 
  feeding 
  both 
  as 
  larva 
  and 
  as 
  adult 
  on 
  the 
  

   juices 
  of 
  the 
  host.
