  in

  the

   forgotten 
  " 
  Erlangen 
  List 
  " 
  of 
  Panzer 
  and 
  Jurine, 
  by 
  J. 
  

   Chester 
  Bradley, 
  M.Sc, 
  Ph.D., 
  Assistant 
  Professor 
  of 
  

   Systematic 
  Entomology 
  in 
  Cornell 
  University, 
  Ithaca, 
  New 
  

   York; 
  communicated 
  by 
  Prof. 
  Gordon 
  Hewitt, 
  F.E.S. 
  

  

  The 
  Chairman 
  explained 
  that 
  this 
  paper 
  was 
  to 
  some 
  extent 
  

   a 
  criticism 
  of 
  the 
  paper 
  referred 
  to 
  in 
  the 
  title, 
  accepting 
  the 
  

   List 
  as 
  valid, 
  but 
  taking 
  exception 
  to 
  some 
  of 
  the 
  principles 
  

   on 
  which 
  the 
  resulting 
  conclusions 
  were 
  drawn. 
  

  

  Mr. 
  Bethune-Baker 
  pointed 
  out 
  that 
  the 
  points 
  at 
  issue 
  

   were 
  covered 
  by 
  the 
  International 
  Nomenclature 
  Code, 
  but 
  

   Mr. 
  MoRiCE 
  remarked 
  that 
  the 
  interpretation 
  of 
  the 
  code 
  

   was 
  not 
  so 
  clear 
  as 
  was 
  generally 
  supposed, 
  and 
  that 
  certain 
  

   American 
  Entomologists 
  did 
  not 
  understand 
  it 
  in 
  tlie 
  generally 
  

   accepted 
  way. 
  

  

  Dificussioih 
  on 
  Fli(jhl 
  of 
  Male 
  BuUerjlies. 
  

  

  Dr. 
  IjON<;staff 
  asked 
  whether 
  Dr. 
  Neave 
  had 
  ever 
  seen 
  

   butterflies 
  flying 
  as 
  it 
  were 
  in 
  patterns, 
  one 
  behind 
  another, 
  

   independently 
  of 
  sex, 
  as 
  he 
  iiad 
  himself 
  seen 
  male 
  butterflies 
  

   doing 
  in 
  Ceylon. 
  

  

  Dr. 
  Neave 
  replied 
  that 
  he 
  had 
  seen 
  certain 
  common 
  African 
  

   Papilios 
  doing 
  so. 
  Col. 
  Jermyn 
  added 
  that 
  he 
  had 
  seen 
  

   Pierids 
  doing 
  so 
  in 
  Assam. 
  • 
  

  

  Mr. 
  Bethunk-Bakkr 
  suggested 
  that 
  they 
  might 
  have 
  been 
  

   following 
  the 
  scent 
  of 
  a 
  virgin 
  female, 
  but 
  it 
  was 
  pointed 
  out 
  

   that 
  this 
  was 
  not 
  likely 
  as 
  they 
  went 
  over 
  the 
  same 
  ground 
  

   in 
  a 
  somewhat 
  complicated 
  pattern, 
  over 
  and 
  over 
  again. 
  

  

  The 
  Chairman 
  instanced 
  the 
  dashing 
  backwards 
  and 
  

   forwards 
  of 
  the 
  males 
  of 
  an 
  Anthophora, 
  and 
  of 
  certain 
  humble- 
  

   bees, 
  but 
  in 
  these 
  cases 
  the 
  cause 
  was 
  a 
  female, 
  and 
  they 
  did 
  

   not 
  come 
  in 
  orderly 
  succession. 
  

  

  Mr. 
  Sheldon 
  referred 
  to 
  the 
  Processionary 
  Caterpillars 
  

   which 
  were, 
  however, 
  guided 
  by 
  a 
  thread, 
  and 
  Dr. 
  Neave 
  said 
  

   that 
  the 
  leading 
  instinct 
  in 
  certain 
  African 
  species, 
  which 
  were 
  

   not 
  guided 
  by 
  a 
  thread, 
  seemed 
  to 
  be 
  individual 
  rather 
  than 
  

   specific, 
  as 
  he 
  had 
  frequently 
  broken 
  the 
  line 
  experimentally, 
  

   and 
  found 
  that 
  the 
  then 
  leading 
  caterpillar 
  was 
  at 
  a 
  loss 
  how 
  

   to 
  proceed.
