102 THE AUSTRALIAN NATURALIST. 
A paper on the “Flora of Marrangaroo” by Dr. Chisholm 
was presented by Mr. Blakely. The President gave an outline 
of the scope of the paper, and proposed that it should be 
printed in the Journal, seconded by Mr. Finckh, and carried. 
Mr. Mackerras then gave a. most interesting account of the 
tife-history of the Mosquito, which was illustrated, not only by 
lantern slides, but by living material under the microscope. He 
outlined the distribution of the insetts, and stressed the differ- 
ences between the species, especially Culea and Anotheles, the 
carrier of malaria. One of the most interesting of the pictures 
was that of a tank full of larvae, which Mr. White had ar- 
ranged. The whole lecture was most fascinating, and opened up 
avenues of work for entomologists and for all also in combining 
to exterminate the scourge. 
April 3rd.—The President (Mr. Shiress) in the chair. Miss 
Day was elected a member. Miss H. Butler exhibited a collec- 
tion of hawk moths and plants indigenous to Bundaberg. Miss 
Harris a series of Broken Hill plants, illustrating xerophytiec 
conditions. Miss Harris read a paper, with drawings, on the 
red sea weed (Callithamnion plumigerum). After discussion, it 
was decided to hold an exhibition and a strong committee was 
appointed to make the necessary arrangements. 
May ist, 1923.—The President (Mr. Shiress) in the chair, 
and there was a good attendance. Dr. Chisholm was duly 
elected a member. Miss Butler exhibited Banksia spinulosa, 
showing abnormal growth, probably due to drought conditions. 
The spike having terminated, a fresh growth has then sprung 
from the apex. Miss McAnene interesting fungi (Geaster) 
known as “Karth stars,” from Bundanoon. Miss Crispo three 
species of sedge found in her garden, the seeds having been 
brought by birds. 
Mr. W. B. Gurney gave an interesting and instructive 
lecture on “House and Garden Pests,” with particular reference 
to boring beetles. The lecture was illustrated with a fine col- 
lection. of specimens, including pieces of affected timber. 
“THE APPROACHING END OF THE AGE OF WILD 
MAMMALS.” 
By A. S. un Souer. 
It is very clear to those familiar with the trend of Zoology 
in a broad sense to-day, that we are approaching the end of a 
very important phase in the history of the wild life on the earth.
