  Notes 
  and 
  exhibition 
  of 
  specimens 
  

  

  Dr. 
  Howard, 
  Mr. 
  Schwarz, 
  and 
  Mr. 
  Caudell 
  gave 
  brief 
  reminiscences 
  of 
  

   the 
  late 
  Dr. 
  W. 
  H. 
  Fox. 
  

  

  Mr. 
  Rohwer 
  exhibited 
  some 
  letters 
  from 
  the 
  late 
  H. 
  F. 
  Bassett 
  to 
  Dr. 
  

   IjNTNER 
  and 
  read 
  one 
  relating 
  to 
  one 
  of 
  Dr. 
  Lintner's 
  reports. 
  

  

  C. 
  J. 
  Bridwell 
  exhibited 
  the 
  elytra 
  of 
  an 
  Elodes 
  on 
  which 
  he 
  has 
  found 
  

   two 
  eggs 
  of 
  a 
  Tachinid 
  parasite 
  and 
  from 
  which 
  he 
  had 
  removed 
  two 
  larvae 
  

   of 
  the 
  fly. 
  He 
  commented 
  on 
  the 
  similarity 
  in 
  the 
  method 
  of 
  attachment 
  of 
  

   the 
  egg 
  to 
  that 
  of 
  the 
  Bruchidae, 
  by 
  a 
  firm 
  cement 
  which 
  gives 
  the 
  larva 
  a 
  

   good 
  purchase 
  for 
  penetrating 
  the 
  hard 
  elytron, 
  in 
  the 
  same 
  manner 
  as 
  the 
  

   bruchid 
  larva 
  penetrates 
  the 
  hard 
  shell 
  of 
  the 
  seed. 
  

  

  Dr. 
  Aldrich 
  was 
  reminded 
  by 
  Mr. 
  Bridwell's 
  remarks 
  of 
  the 
  Tachinid 
  eggs 
  

   that 
  are 
  sometimes 
  found 
  on 
  the 
  adults 
  of 
  the 
  potato 
  beetle, 
  stating 
  that 
  

   nothing 
  has 
  ever 
  been 
  reared 
  from 
  these 
  eggs 
  and 
  that 
  they 
  cannot 
  be 
  those 
  of 
  

   Doryphorophaga 
  since 
  this 
  has 
  a 
  piercer 
  and 
  probably 
  deposits 
  its 
  eggs 
  within 
  

   the 
  host. 
  

  

  Dr. 
  EwiNG 
  had 
  found 
  these 
  eggs 
  and 
  had 
  succeeded 
  in 
  getting 
  them 
  to 
  

   hatch, 
  but 
  had 
  never 
  reared 
  the 
  adult 
  fly. 
  

  

  Mr. 
  Caudell 
  told 
  of 
  having 
  received 
  specimens 
  of 
  Zorotypus 
  from 
  Hawaii 
  

   and 
  thought 
  it 
  probably 
  a 
  species 
  introduced 
  from 
  the 
  East 
  Indies. 
  He 
  

   also 
  exhibited 
  specimens 
  of 
  a 
  rare 
  walkingstick-like 
  mantid 
  that 
  Dr. 
  .C. 
  J. 
  

   Drake 
  had 
  found 
  in 
  considerable 
  numbers 
  in 
  Mississippi. 
  

  

  Mr. 
  CuSHMAN 
  spoke 
  of 
  the 
  confusion 
  resulting 
  from 
  an 
  old 
  misdetermi- 
  

   nation 
  of 
  Habrocracon 
  brevicornis 
  (Wesmael), 
  whereby 
  the 
  name 
  has 
  long 
  

   been 
  associated 
  with 
  the 
  common 
  parasite 
  of 
  stored 
  grain 
  insects. 
  The 
  re- 
  

   cent 
  rearing 
  of 
  the 
  true 
  brevicornis 
  from 
  the 
  European 
  Corn 
  Borer 
  in 
  imported 
  

   material 
  has 
  been 
  the 
  means 
  of 
  correcting 
  the 
  error. 
  

  

  Mr. 
  Gahan 
  discussed 
  the 
  habits 
  of 
  a 
  recently 
  discovered 
  parasite 
  of 
  Di- 
  

   abrotica 
  vittata 
  adults, 
  Syrrhizus 
  n. 
  sp., 
  as 
  given 
  him 
  by 
  the 
  discoverer, 
  Mr. 
  

   W. 
  V. 
  Balduff, 
  of 
  the 
  Ohio 
  State 
  Agricultural 
  Experiment 
  Station. 
  Mr. 
  

   Gahan 
  outlined 
  the 
  similarities 
  and 
  differences 
  between 
  the 
  habits 
  of 
  this 
  in- 
  

   sect 
  and 
  of 
  the 
  common 
  parasite 
  of 
  lad> 
  -bird 
  beetles, 
  Dinocampus 
  terminatus 
  

   Nees.
