  Mr. 
  F. 
  Smith's 
  Monograph 
  

  

  The 
  number 
  of 
  previously 
  described 
  species 
  appears 
  to 
  be 
  

   twenty 
  ; 
  to 
  this 
  I 
  now 
  add 
  fifteen, 
  making 
  the 
  total 
  thirty-five. 
  

   From 
  these 
  I 
  propose 
  to 
  remove 
  the 
  species 
  of 
  the 
  Old 
  World, 
  

   four 
  in 
  number, 
  and 
  form 
  a 
  new 
  genus 
  for 
  their 
  reception 
  ; 
  and 
  a 
  

   second 
  new 
  genus 
  I 
  create 
  for 
  two 
  other 
  species, 
  differing 
  very 
  

   materially 
  from 
  all 
  others 
  in 
  having 
  the 
  abdomen 
  peduncu- 
  

   lated 
  and 
  rounded 
  in 
  the 
  females, 
  the 
  neuration 
  of 
  their 
  wings 
  

   being 
  also 
  quite 
  distinct 
  from 
  Cryptocerus. 
  When 
  a 
  knowledge 
  

   of 
  all 
  the 
  sexes 
  shall 
  have 
  been 
  obtained, 
  it 
  will 
  in 
  all 
  probability 
  

   be 
  necessary 
  to 
  make 
  further 
  subdivisions. 
  Indeed, 
  I 
  retain 
  in 
  the 
  

   genus 
  Cryptocerus 
  a 
  species 
  from 
  Adelaide 
  with 
  some 
  reluctance 
  ; 
  

   but 
  having 
  only 
  one 
  specimen, 
  I 
  leave 
  it 
  there 
  for 
  future 
  investi- 
  

   gation, 
  being 
  unwilling 
  to 
  destroy 
  it 
  by 
  dissecting. 
  In 
  its 
  antennae 
  

   I 
  cannot 
  detect 
  more 
  than 
  ten 
  joints, 
  all 
  other 
  neuters 
  having 
  

   eleven 
  ; 
  the 
  basal 
  joint 
  of 
  the 
  flagellum 
  is 
  frequently 
  hidden 
  in 
  a 
  

   cavity 
  at 
  the 
  apex 
  of 
  the 
  scape, 
  but 
  such 
  does 
  not 
  appear 
  to 
  be 
  

   the 
  case 
  in 
  the 
  species 
  from 
  Adelaide. 
  

  

  Having 
  the 
  means 
  of 
  describing 
  for 
  the 
  first 
  time 
  the 
  male 
  and 
  

   female 
  of 
  a 
  closely 
  allied 
  genus, 
  the 
  Daceton 
  of 
  Perty, 
  I 
  have 
  

   given 
  both 
  descriptions 
  and 
  figures 
  of 
  the 
  sexes 
  ; 
  this 
  genus, 
  in 
  

   the 
  neuration 
  of 
  the 
  wings, 
  will 
  be 
  found 
  very 
  nearly 
  to 
  agree 
  

   with 
  the 
  genus 
  Cryptocerus. 
  

  

  I 
  have 
  also 
  added 
  to 
  my 
  present 
  memoir 
  a 
  description 
  of 
  a 
  new 
  

   and 
  allied 
  genus 
  from 
  New 
  Zealand, 
  very 
  remarkable 
  for 
  having 
  

   only 
  five 
  joints 
  in 
  the 
  antennae 
  of 
  the 
  workers. 
  

  

  I 
  have 
  much 
  pleasure 
  in 
  recording 
  still 
  further 
  obligations 
  to 
  

   Mr. 
  Bates, 
  who 
  discovered 
  the 
  male 
  and 
  female 
  of 
  the 
  genus 
  

   Daceton 
  ; 
  both 
  sexes 
  are 
  in 
  the 
  collection 
  of 
  the 
  British 
  Museum. 
  

   I 
  am 
  greatly 
  indebted 
  to 
  my 
  friend 
  Mr. 
  Westwood 
  for 
  the 
  per- 
  

   mission 
  to 
  describe 
  four 
  new 
  species 
  from 
  his 
  collection 
  ; 
  nine 
  

   new 
  species 
  are 
  described 
  from 
  specimens 
  in 
  my 
  own 
  cabinet, 
  

   the 
  possession 
  of 
  which 
  in 
  the 
  first 
  instance 
  induced 
  me 
  to 
  under- 
  

   take 
  a 
  monograph 
  of 
  the 
  genus 
  Cryptocerus.
