  species, 
  as 
  are 
  some 
  of 
  our 
  red 
  and 
  black 
  Hawaiian 
  

   Nesoprosopis, 
  since 
  the 
  curved 
  sweeping 
  hairs 
  of 
  the 
  front 
  legs 
  

   are 
  well 
  developed 
  and 
  have 
  noticeably 
  dilated, 
  or 
  spatulate, 
  

   apices. 
  

  

  I 
  should 
  have 
  said 
  above, 
  that, 
  as 
  conjectured 
  by 
  Cockerell, 
  

   r. 
  Smith 
  must 
  have, 
  by 
  confusion, 
  dissected 
  some 
  wasp 
  in 
  mis- 
  

   take 
  for 
  the 
  wasp-like 
  Hylaeoides 
  above 
  referred 
  to, 
  since 
  his 
  

   figures 
  of 
  the 
  mouth-parts 
  are 
  those 
  of 
  a 
  wasp 
  and 
  not 
  like 
  

   those 
  of 
  this 
  bee, 
  which 
  I 
  have 
  myself 
  dissected."

  Lithurgus. 
  

  

  Dr. 
  Perkins 
  then 
  exhibited 
  an 
  anomalous 
  lAthurguLS, 
  and 
  

   made 
  the 
  following 
  remarks 
  : 
  

  

  "The 
  bee 
  here 
  exhibited 
  is 
  one 
  of 
  the 
  Megachilidae 
  and 
  is 
  a 
  

   comparatively 
  recent 
  introduction 
  into 
  the 
  Hawaiian 
  islands. 
  

   The 
  first 
  specimen 
  taken 
  was 
  caught 
  by 
  Mr. 
  Marlatt 
  of 
  the 
  

   Department 
  of 
  Agriculture 
  at 
  Washington, 
  when 
  in 
  company 
  

   with 
  Koebele 
  and 
  myself 
  at 
  Waialua, 
  I 
  think 
  in 
  1900. 
  On 
  this 
  

   occasion 
  we 
  took 
  plenty. 
  If 
  the 
  characters 
  given 
  by 
  Ashmead 
  

   and 
  others 
  for 
  the 
  genera 
  of 
  this 
  family 
  be 
  considered 
  adequate 
  

   and 
  correct, 
  then 
  this 
  bee 
  constitutes, 
  I 
  believe, 
  an 
  undescribed 
  

   genus, 
  or 
  it 
  may 
  be 
  considered 
  as 
  a 
  species 
  of 
  Lithurgus 
  

   sens. 
  lat. 
  Ashmead 
  states 
  that 
  European 
  Lithurgus 
  have 
  no 
  

   pulvilli, 
  while 
  other 
  American 
  writers 
  state 
  that 
  American 
  

   species 
  described 
  under 
  the 
  genus 
  have 
  a 
  pulvillus 
  at 
  least 
  in 
  

   the 
  male 
  and 
  a 
  new 
  genus 
  has 
  been 
  described 
  for 
  one 
  of 
  these. 
  

   This 
  species, 
  however, 
  is 
  said 
  to 
  have 
  3-jointed 
  labial 
  palpi. 
  

   The 
  Hawaiian 
  insect 
  has 
  4- 
  jointed 
  Labial 
  palpi, 
  its 
  mandibles 
  

   are 
  Lithurgus-like, 
  3-dentate 
  at 
  apex, 
  and 
  there 
  is 
  a 
  pulvillus 
  at 
  

   least 
  in 
  the 
  male. 
  Its 
  other 
  oral 
  characters 
  are 
  not 
  at 
  all 
  

   Megachile-like. 
  Its 
  maxillary 
  palpi 
  are 
  4-jointed 
  not 
  2-jointed. 
  

   (Ashmead, 
  however, 
  gives 
  Megachile 
  4 
  joints 
  to 
  these 
  organs!) 
  

   The 
  tongue 
  is 
  not 
  folded 
  so 
  as 
  to 
  merely 
  lie 
  beneath 
  the 
  head 
  

   in 
  repose, 
  but 
  is 
  extended 
  straight-back 
  along 
  the 
  sternum, 
  

   which 
  is 
  channeled 
  for 
  its 
  reception, 
  while 
  the 
  labrum 
  is 
  much 
  

   less 
  long 
  than 
  in 
  Megachile 
  and 
  projects 
  very 
  little 
  backward 
  

   from 
  the 
  clypeus."

  Odynery^. 
  

  

  Dr. 
  Perkins 
  then 
  read 
  some 
  remarks 
  on 
  the 
  "Habitus 
  and 
  

   Structure 
  of 
  Australian 
  Odynerus 
  and 
  Allies 
  compared 
  with 
  

   those 
  of 
  Hawaii."
