58 THE AUSTRALIAN NATURALIST, ae F 
The following were the exhibits:— 
Dr. R. J. Tillyard exhibited, by invitation of the 
Council, a large case of Dragonflies (Order Odonata), 
collected within fifty miles of Sydney, and totalling nearly 
fifty species. These ranged from the gigantic Petalura, : 
with a wing-expanse ranging up to five inches, to the tiny 
-Agriocnemts hyacinthus and Ischnura aurora, two 
brightly-coloured little gems, with an expanse of only 
about three-quarters of an inch. The Sydney district is  _ 
particularly rich in groups that are peculiar to Australia, S 
such as, for instance, the Synthemini, Cordulephyini, and 
the genera Synlestes and Austroacschna. 
. Mr. G. A. Waterhouse’s exhibit comprised a long and “xa 
extensive series of the butterfly 7istphone abeona, Don., 
from Southern Queensland, coastal New South Wales, and 
Eastern Victoria. All the known races were shown, the 
broad orange-branded ones occurring in the south and 
'. the narrow cream-banded races in the northern limits of ad 
the species. The manner in which the two types of races ; 
intermingled at Port Macquarie was illustrated by a large 
number of specimens caught within a few days of one 
-another and within five miles of one another. This re- 
markable series showed every intergrade of colour and _- 
_ pattern between the races to the south and north of Port 
-_ Maequarie. Mr. Waterhouse also exhibited a large drawer 
of well-known New South Wales butterflies, including 
- examples of the various families to be found in N.S.W.
