The South Australian Naturalist. 
EVENING LECTURE, by Dr. PULLEINE 
On ‘'Tasmanian Holidays,” May 19, 1925. 
Dr. Pullcine in his characteristic breezy style gave a short 
account of his very successful journeys in the North~\\ est of 
Tasmania in search of the remains of the aborigines of that island. 
By means of pictures, and specimens he illustrated kitchen-mid- 
dens and various relics of this vanished race. 
The finding of the remains of rude “houses” was an import- 
ant advance in our knowledge of these backward people, 
EVENING LECTURES, JULY 21, 1925. 
Miss Macklin, B.Sc., gave a most interesting lecture on Lich- 
ens, part of the^ lecture being reproduced in this issue. 
Mr. E. H. Ising gave a short account of a “Holiday at Beach- 
port,” dealing with the natural history of the place. 
EVENING LECTURE by Mr. A. M. LEA. 
“Travels in the Pacific.” May 19, 1925. 
Mr Lea explained that he had been selected by the Fijian Gov- 
ernment to make an investigation into the occurence and and life 
history of a small moth {Levuana iridescens) which in infesting the 
coconut trees and doing so much damage that they become weak- 
ened and occasionally die. So great is the damage done by the 
pest^ that the principal industry of the islands, the preparation 
of Copra from the Cocoanuts, is threatened with absolute destruc- 
tion. The moth is probably not indigenous but has been accident- 
ally introduced. Mr. Lea searched for its parasite, visiting the 
islands of Torres Straits, Java etc. 
In Java he was successful in finding and collecting a parasite 
01 a closely allied moth {Brachatona Catorantha) of which he ob- 
tamed large numbers. Unfortunately they died before reaching 
iji on the return journey. The parasite proved to be so short 
lived that it was found Impossible to land it safely in Fiji. Mr. 
Lea s opinion is that an aeroplane Bight is the only method of 
p acing the parasite in Fiji. Considering the importance of the 
industry to Fiji this should be possible of arrangement. 
ihe lecturer related many incidents of his travels in the various 
islands and the lecture was one of great interest and scientific 
'^'ork will result in as 
gieat benefit as did the former research when his investigation 
■ the life history of the wheat weevil and means for its destruc- 
tion were the direct causes of saving millions to Australia..
