NOTES AND EXHIBITS. 
Mr. Froggatt exhibited specimens of two species of Scale 
Insects and parasites bred therefrom; with the following Note: — 
"About Sydney leery a purchasi is not a common coccid, seldom 
being found in more than twos or threes upon the small branches, 
chiefly of Acacia discolor, in the bush. This year my colleague 
Mr. H. G. Smith had a young tree of Acacia bailey ana in his 
garden at Tempe covered with this scale, and he brought me a 
large spray swarming with adult females, which I enclosed in a 
box. From these I bred some hundreds of small chalcid 
parasites ( Euryischia lestophoni, Riley), and also a number of 
dipterous parasites ( Cryptochaeton iceryce, Willist.). At my 
request, Mr. Smith observed the coccids in situ, and he soon 
found them falling off; and before very long they were all dead. 
No lady birds ( Coccinellidce ) or their larvae were seen upon the 
tree, which was cleared of the pest by the minute parasites above 
mentioned; and it seems evident that in this part of Australia 
we owe much more to these parasites than to their coleopterous 
enemies for our immunity from the cottony cushion or fluted 
scale insects as serious pests. The Floridian scale ( Icerya rosea?, 
Riley and Howard) has been very plentiful upon the foliage of 
the Grevilleas and Hakeas on the Illawarra line, and from them 
I have bred the same species of dipterous parasite, and numbers 
of the secondary parasite, a chalcid that is parasitic upon the fly 
larvse Ophelosia crawfordi, Riley, and is therefore not an enemy 
of the scale insects." 
Mr. Waite sent for exhibition a specimen of Peripatus 
leuckartii, Sang., from Colo Yale, near Mittagong, and recorded 
localities for other specimens, including some collected by Mr. C. 
J. McMasters at Moree. As Peripatus has been supposed hitherto 
to be confined to the table-land and coastal districts, its occurrence 
so far inland as Moree is particularly noteworthy. 
Professor David exhibited mounted and bulk specimens of 
diatomaceous earth, sanidine tuff, trachyte, and trachyte ash
