34 THE AUSTRALIAN NATURALIST. 
Miss Caldwell, Dr. J. B. Cleland, Messrs. A. P. 
Kemp, and T. P. Dodd, and Masters T. P. Dodd and R. 
G. Dodd, were elected members. 
Mr. Shiress exhibited the following plants:—Trocho- 
carpa laurina, Drimys dipetala, casuarina distyla, Grevil- 
lea mucronulata, Bulbophyllum minutissimum, Alsophila 
Leichhardtiana, collected at Conway’s Creek at its junc- 
tion with Berowra Creek, and mentioned having noted the 
following unusual birds in the vicinity :—Gray Bill Magpie 
(Strepera versicolor), Diamond Dove (Geopelia cuneata), 
Quail (Turniz maculosa). 
Mr. H. G. Smith delivered a most interesting lecture 
on ‘‘Some Essential Oils from Australian Plants,’’ illus- 
trated by lantern slides and samples of oils from a variety 
of trees. The lecture was one of special economic value, 
apart from its scientific interest, throwing much light on 
the subject of the evolution of the Eucalypts. 
EXHIBIT OF PARASITIC WASPS, MARCH, 1916. 
(By L. Gallard.) 
The exhibit consisted of four species of parasites of 
Longicorn Beetles, five of Weevils, and one of a Fruit 
Fly. 
Longicorn Parasites—No. 1. Tivo specimens of the, 
large Megalyrid Wasp, Megalyra Shuckardi, a very for- 
midable-looking insect. The body is stout, of a shiny 
black, relieved with white pubescence. The female is about 
an inch in length, and is provided with a triple ovipositor 
three to three and one-half inches long. In the centre, the 
actual ovipositor is a slender tube, protected by the double 
sheath. This species is parasitic on Phoracantha -larve, 
which form deep burrows in the trees. The exceptionally 
long ovipositor enables the wasp to reach the host larva. 
No. 2. A pair of Megalyra fasciipennis. This species 
is somewhat smaller than the former, has clouded spots 
‘on the wings, and carries the ovipositor curled over the 
back, instead of straight behind, as in M. Shuckardi. 
‘Both species have similar habits, and are described 
in Froggatt’s Australian Insects. Unlke many other
