Unfortunately I am unable to provide very much technical information about them.I can tell you they were collected in Toowoomba, Queensland,Australia, probably along suburban footpaths, waterbird habitat or my mothers backyard !
This top page is what I always called a Stag Beetle. I have found out they are part of Rhinocerous Beetle family which covers many similar looking beetles with varying degrees of spiky and spiny features.

This second page has a few mysterious small black and brown insects. I know the highly un-technical name of the "click beetle" (middle left) which (when we were children) we used to put our finger on their back they would click and jump . The green cicada is also a familiar insect . Maybe the one above it is a Christmas beetle ???
I really enjoyed drawing ( or is it painting?) these. I also wanted to write all over it with notes. I have kept most of the beetles and bugs to draw again another day....
