A few of the handsome “native bees” (Podalirius emendatus ) , 
cingulatus, and I believe aeruginosus, were captured on the bloom 
of a small species of Goodenia. Our best capture was the laie 
and undescribed female of one of the Fossorial wasps, Agriomyia 
albopictus, Sm. The male “Type” is in the British Museum, named 
by Smith in 1859. 1 captured a male specimen again in 1901, 
and have taken one or two specimens at long intervals since, but 
although I have diligently searched, it has been labor m 
vain on my part for nine years. This may seem a striking fact 
to those who are not workers in the cause of Science, whereas 
they are so used to disappointment that when they do meet with 
success after the long weary search and waiting, it is their reward 
for having followed Nature’s devious ways with such patience 
and observation.

NORTH BEACH, 5™ MARCH, 1910. 
Owing probably to the trying weather experienced during 
the previous few days only seven members attended this excursion. 
The rendezvous was left at a few minutes to one o’clock and the 
party proceeded in two buggies via Charles Street and the Wan- 
neroo and North Beach Roads. 
The route lay for the most part through the narrow belt ol 
Tuart forest which extends along the west coast from a few miles 
north of Perth to the vicinity of Busselton. Some fine specimens 
of this tree ( Eucalyptus gomphucephala) were noticed. The road 
runs in a northerly direction for seven miles over hills of drift 
sand, then turns sharply towards the west, where it soon runs 
into country occupied by the coastal limestone. 
North Beach was reached at twelve miles from the Perth 
Town Hall, the time taken en route being i| hours. At North 
Beach the fora mini feral limestone of the Coastal Series forms a 
low line of cliffs broken by little sandy beaches. The sand on the 
latter appears to be mainly vitreous quartz with a fair proportion 
of shell fragments. No foraminifera were seen in the sing e 
sample brought back. In this respect it differs essentially from 
the sand on the beaches of the islands off Fremantle. 
Several species of sponges were seen on the beaches, also 
numerous shells. These, however, did not prove of great interest 
to the Concliologist of the party, Mr. Bardwell, who was prevented 
by the high tide from securing living specimens. 
Some speculation has been indulged in as to the age of the 
fossils frequently associated with the coastal limestone. The\ 
occur in bunches under conditions which make.it doubtful vhethei 
they are contemporaneous with the formation of the lock or 
deposited in crevices therein more recently. Some of the fossils 
at Cottesloe appear to be contemporaneous. At North Beach
