| Protohymen
permianus Tillyard
1924. Wing
is 11 mm long. From an extinct insect order, Megasecoptera.
The wing
venation is remarkably well-preserved, as is that
of many of the Elmo insect fossils. Often wings, since they are relatively durable,
are the only part of insects found as fossils. |

Dunbaria
fasciipennis
Tillyard 1924.
The counterpart to the fossil on the
front cover.
When the rock
layer was split, these two fossils were
on the respective halves of the rock.
From an extinct insect order, Palaeodictyptera.
Wingspan 36 to 37 mm. These insects lived in the Permian
Period about 260 million years ago.
The pictures on the front and back covers
are from the original glass plate negatives
used to illustrate the type descriptions by
R.J. Tillyard in 1924, and are provided courtesy
