  Some 
  thirty 
  species 
  of 
  Australian 
  Odynerus, 
  or 
  closely 
  allied 
  

   forms, 
  were 
  exhibited, 
  showing 
  the 
  great 
  variety 
  of 
  appearance 
  

   and 
  bright 
  colours 
  as 
  compared 
  with 
  the 
  remarkably 
  general 
  

   blackness 
  of 
  the 
  Hawaiian 
  species. 
  The 
  variety 
  of 
  structure 
  

   was 
  also 
  large. 
  A 
  few 
  typical 
  Odynerus 
  of 
  other 
  countries 
  

   were 
  also 
  exhibited, 
  and 
  Dr. 
  Perkins 
  remarked 
  on 
  the 
  necessity 
  

   of 
  the 
  study 
  of 
  exotics 
  ; 
  with 
  the 
  study 
  of 
  a 
  few 
  Frosopis 
  and 
  

   Odynerus 
  one 
  knows 
  all 
  the 
  Hawaiian 
  species. 
  

  

  In 
  a 
  discussion 
  on 
  the 
  habits 
  of 
  aculeate 
  Hymenoptera, 
  Dr. 
  

   Perkins, 
  in 
  reply 
  to 
  Dr. 
  Cobb, 
  stated 
  that 
  the 
  caterpillars, 
  

   stored 
  up 
  for 
  the 
  food 
  of 
  the 
  larvae, 
  were 
  put 
  through 
  a 
  process 
  

   of 
  stinging 
  and 
  malaxation. 
  Dr. 
  Cobb 
  had 
  never 
  observed 
  the 
  

   caterpillars 
  to 
  be 
  dead 
  or 
  even 
  injured. 
  Mr. 
  Swezey 
  stated 
  

   that 
  sometimes 
  the 
  caterpillars 
  are 
  so 
  insufficiently 
  paralized 
  

   as 
  to 
  pupate, 
  and 
  even 
  crawl 
  about 
  after 
  being 
  stung. 
  The 
  larva 
  

   of 
  the 
  bee 
  is 
  hung 
  up 
  in 
  the 
  cell 
  and 
  feeds 
  by 
  descending 
  onto 
  

   the 
  caterpillar. 
  

  

  Dr. 
  Cobb 
  observed 
  that 
  the 
  drawing 
  of 
  insects 
  was 
  more 
  

   desirable 
  when 
  from 
  living 
  specimens. 
  Pie 
  had 
  found 
  that 
  he 
  

   could 
  paralyze 
  them 
  by 
  means 
  of 
  bee 
  stings 
  ; 
  while 
  a 
  wasp's 
  

   sting 
  would 
  kill 
  an 
  insect, 
  the 
  Odynerus 
  sting 
  would 
  only 
  

   paralyze. 
  He 
  had 
  produced 
  paralysis 
  in 
  Diptera 
  by 
  either 
  

   inserting 
  the 
  bee 
  sting 
  poison 
  on 
  the 
  point 
  of 
  a 
  needle 
  in 
  the 
  

   neighborhood 
  of 
  the 
  thoracic 
  ganglia 
  or 
  by 
  presenting 
  the 
  same 
  

   parts 
  of 
  the 
  specimen 
  to 
  the 
  bee-sting 
  directly. 
  An 
  insect 
  so 
  

   stung 
  retained 
  its 
  natural 
  color 
  and 
  position 
  ideally 
  for 
  draw- 
  

   ing. 
  

  

  Mr. 
  Swezey 
  stated 
  that 
  he 
  never 
  was 
  severely 
  stung 
  by 
  

   Odynerus 
  in 
  all 
  his 
  handling 
  of 
  them. 
  

  

  Mr. 
  Giffard 
  exhibited 
  specimens 
  and 
  presented 
  the 
  following
