chrysum rutidolepis, a mountain variety. He also gave 
an interesting account of the staminate and _pistillate 
flowers of the three local species of Caustis, and notes 
on Arthropteris tenella (J.Sm.), (Polypodium tenellum, 
Forst). The genus, Arthropteris, was established by J, 
Smith to contain A. obliterata (R.Br.), A. tenella (Sm.), 
and Nephrolepis trichomanoides (Sm.). Hooker followed 
Smith’s ‘classification, Bentham agreed with Forster, and 
was followed by Moore and Betche. The genus has now 
been restored by Christenson, the latest authority on 
Filices, and will contain two species only, A. tenella and 
A. obliterata, Nephrolepis trichomaniodes being sunk as 
a synonom of the latter.’ Nephrolepis cordifolium and 
Davallia pysadate and D. dubia were also commented 
upon. 
Mr. Froggatt exhibited a gall produced by Apro- 
morpha Iletcherii, a fine series of this remarkable coccid, 
which produces large swellings on the branchlets of the 
Box (Hucalyptus). The true cylindrical oval chambers 
containing the yellow top-shaped coccids, enveloped in a 
floury secretion, are embedded in the aborted woody tis- 
sue beneath the bark. To the ordinary observer the pre- 
sence of the coccid gall would not be noticed, as the apex 
of the gall is just level with the surface of the bark 
and often covered with dry flakes. 
When the bark is removed the upper portion or cap 
of the gall comes away with the bark, out of which 
it is apparently formed, and from which it is easily de- 
tached, as a little hard cone with an apical orifice. There 
may be half-a-dozen or more of these hidden galls in one 
of the lumps of aborted woody tissue. The specimens 
shown were collected on a tree on the banks of the Mur- 
rumbidgee near Hay, New South Wales. 
2nd May, 1916.—The chair was oecupied by the Pre- 
sident, Mr. W. W. Froggatt, F.L.S., and about 40 present. 
The Hon. Secretary announced that the Selection 
Committee had awarded the prize for the cover of The 
Australian Naturalist to Mr. H. Zeck. 
On the motion of Mr. Finckh it was decided to set 
apart a table for members to exhibit any Natural His- 
tory specimens which they wished named or to exchange, 
donate or sell. 
Miss Bayfield exhibited a spider taken from a lemon 
tree, having a remarkable bag-shaped egg case. Mr. 
Shiress, a specimen of Pavonia hastata, a representative
