Hi Len,
This is a female Stump Stabber or Giant Ichneumon,
Megarhyssa atrata, and the eggs she lays will hatch into larvae that will feed upon and parasitize the larvae of Wood Wasps that are feeding beneath the surface.  Has you checked out our featured postings, you would have seen that the Stump Stabber is our Bug of the Month for July 2014.  The green membrane is part of the structure of the long ovipositor which allows the Stump Stabber to lay her eggs well below the surface of the bark.
