  grandest 
  vista 
  we 
  have 
  of 
  Triassic 
  insects. 
  Some 
  of 
  the 
  speci- 
  

   mens 
  are 
  described 
  in 
  publication 
  253 
  of 
  the 
  Queensland 
  Geolo- 
  

   gical 
  Survey 
  and 
  in 
  several 
  papers 
  published 
  in 
  the 
  Proceedings 
  

   of 
  the 
  Linnean 
  Society 
  of 
  New 
  South 
  Wales 
  for 
  1917 
  and 
  1918. 
  

   Nearly 
  all 
  the 
  species 
  and 
  most 
  of 
  the 
  genera 
  are 
  of 
  course 
  new 
  

   to 
  science, 
  and 
  there 
  are 
  even 
  new 
  orders 
  described. 
  

  

  Some 
  of 
  the 
  most 
  interesting 
  material 
  has 
  now 
  been 
  discussed. 
  

   The 
  commonest 
  forms 
  are 
  Coleoptera, 
  of 
  which 
  14 
  forms 
  are 
  

   named. 
  Of 
  Blattoidea 
  there 
  is 
  1 
  species, 
  Protorthoptera 
  2, 
  Pro- 
  

   todonata 
  1, 
  Odonata 
  3, 
  Mecoptera 
  1, 
  Prothemiptera 
  1, 
  Hemiptera 
  

   4, 
  Neuroptera 
  1, 
  Trichoptera 
  2, 
  and 
  Protomecoptera 
  1. 
  The 
  

   oldest 
  known 
  dragon-fly 
  is 
  here 
  named 
  Mesophlebia 
  antinodalis. 
  

   The 
  panorpid 
  Mesochorista 
  proavita 
  stock 
  has 
  lived 
  on 
  until 
  

   to-day 
  almost 
  unchanged, 
  and 
  is 
  a 
  relic 
  just 
  as 
  is 
  Ceratodus 
  

   among 
  the 
  fishes. 
  

  

  The 
  author 
  remarks 
  that 
  Austromylacrites 
  and 
  Mesogereon 
  

   "are 
  little 
  removed 
  from 
  certain 
  Carboniferous 
  and 
  Permian 
  

   insects 
  of 
  the 
  northern 
  hemisphere. 
  Others 
  are 
  scarcely 
  dis- 
  

   tinguishable 
  from 
  forms 
  existing 
  in 
  Queensland 
  at 
  the 
  present 
  

   day." 
  "The 
  Ipswich 
  fossils 
  show 
  that 
  it 
  was 
  the 
  same 
  in 
  Aus- 
  

   tralia 
  in 
  the 
  Trias 
  as 
  it 
  is 
  to-day, 
  and 
  that 
  the 
  Australian 
  fauna 
  

   then, 
  as 
  now, 
  combined 
  numerous 
  archaic 
  types 
  with 
  certain 
  

   highly 
  specialized 
  forms 
  peculiar 
  to 
  the 
  continent." 
  Upon 
  the 
  

   whole, 
  the 
  Ipswich 
  Triassic 
  insects 
  are 
  more 
  specialized 
  than 
  

   those 
  of 
  the 
  Paleozoic 
  and 
  more 
  archaic 
  than 
  those 
  of 
  the 
  lower 
  

   Lias. 
  

  

  These 
  Triassic 
  insects 
  are 
  of 
  fair 
  size, 
  and 
  some 
  are 
  even 
  large, 
  

   but 
  in 
  the 
  clay 
  pits 
  of 
  Jurassic 
  age 
  at 
  St. 
  Peter's, 
  near 
  Sydney, 
  

   New 
  South 
  Wales, 
  the 
  fossil 
  insects 
  are 
  much 
  larger. 
  From 
  this 
  

   locality 
  Tillyard 
  describes, 
  among 
  others, 
  a 
  protorthopterid, 
  

   Mesotitan 
  giganteus, 
  about 
  20 
  inches 
  across 
  the 
  wings, 
  and 
  seem- 
  

   ingly 
  related 
  to 
  the 
  largest 
  of 
  all 
  known 
  insects,'

  the 
  Coal 
  

   Measures 
  of 
  Commentry,
