fob ie. OF PROCEEDINGS 
OF THE 
Roval Society of South Australia, 
— 
OrDINARY Meretinc, NovEMBeER 1, 1898. 
W. L. Crevanp, M.B. (President) in the chair. 
Batitot.—A. Purdie, M.B., Saml. Hughes, B.Sc., and Max 
Koch were elected Fellows. 
Exuipits.—A. ZieTz, Assistant Director Museum, exhibited 
eleven species of Australian wrens (Maluride) from Museum. 
J. G. O. Tepper exhibited mineral specimens from Coolgardie and 
galls from Acacia. Prof. Tare two plant specimens from Mount 
Lyndhurst, collected by Mr. Koch, Acacia papyrocarpa and 
Cochorus longipes. W. HowcuIN a specimen of Eocene limestone 
from a brick-pit at Southwark, showing casts of Turritelle and 
other shells. This stone evidently occupied site of old river bed, 
and had lost by leaching most of its calcareous constituents. A 
section of the pit gives 20 ft. of brick-earth from the surface, 
9 ft. loose river sand and coarse gravel below that, then 16 ft. 
of tenaceous red clay. At 45 ft. water was tapped. He con- 
sidered that the occurrence of the old river bed in this un- 
expected position indicates a change in the line of drainage, and 
is concommitant with the oscillations of level that have occurred 
along the seaboard in recent geological time. 
OrDINARY Meetinc, DECEMBER 6, 1898. 
W. L. Crevanp, M.B. (President) in chair. 
Exursits.—J. G. O. Tepper, F.L.S., exhibited specimens of 
the bee-flies and their rat-tailed pupa cases (Hnstalis, sp.) with 
queen and worker bees. Also galls from Acacia retinoides pro- 
duced by gall midges (Dzplosis) a number of which were shown, 
together with parasites bred with them; minute Chalcidid wasps, 
the minute beetle of the family Carylophide and larve, and an 
Anthrinus beetle, the larve of which must have lived in the 
interstices of the galls.
