to the depredations of rats, bandicoots, wallabies and 
opossums, which eat every nut they can find, and it would 
mean a total loss if the nuts were exposed to these pre- 
dators for long. In fact, between the natives and the wild 
animals it is a great wonder that the Bunya pine managed 
to exist in the numbers present before milling the timber 
on a large scale commenced. This may explain the com- 
paratively limited distribution of the species as compared 
with the hoop pine. 
In conclusion, it may be stated that the Bunya pine 
has played a large and important part in the social and 
economic life of the aboriginal inhabitants of south-eastern 
Queensland, and a lesser extent, perhaps, in the whole of 
Australia, because at the triennial meetings tribal cor- 
roborees from far districts would be enacted and then 
carried away and replayed at other places, and thus passed 
gradually far and wide. Owing to the overgrowth of bark 
and to the sawunilling industry, together with the natural 
death of the old marked trees, most visible traces of the 
association of the natives and the trees will, in the course 
of time be lost. Even in the Bunya Mountains National 
Park, where the best remaining collection of marked trees 
is to be seen, these relics of the past will within a com- 
paratively few years disappear, due to natural agencies. 
In order to provide material for future study, it is sug- 
gested that one or more Bunya logs be preserved with the 
bark on, in some suitable place such as a museum, for in 
future years such specimens would be an invaluable asset 
to any ethnological and historical collection. 
DESCRIPTIONS OF SOME CIIALCID WASPS. 
By A. A. Girault, B.Sc. 
The following species have been reared mostly from 
various pest insects; and on this account ought to have 
speedy publication. Also they form contributions to a 
monograph now completed (MSS.). The types are in 
some Australian museum. The descriptions follow. 
Gyrolasella margiscutellum nov. 
In my revision of the species runs to trifasciatifrons r 
but the face is not trifasciate, the wings are always hyaline, 
there are no distinct transverse lemon abdominal marginal 
marks, and the species is smaller and marked as follows: 
Green, flavous as follows — Head, except a large central 
mark upon the cheek, a spot upon the face against the eye 
above the antennae, a broken line through the antennae
