carry on the work in connection with the library during Mr. 
Murray’s absence. 
In addition to the Ordinary Monthly meetings, eleven 
Council meetings have been held during the year, at which the 
ordinary routine business has been transacted. ‘I'he usual four 
parts of our official journal, “The Australian Naturalist,” have 
been published and issued to our members and other subscribers, 
as well as to kindred societies and other scientific institutions. 
For the services of our Hon. Editor, Mr. T. Steel, who has 
conducted the journal, the Couneil offers its best thanks. 
The Council has also given consideration to the matter of 
holding an exhibition of wild flowers and certain groups of our 
native fauna, with the result that St. James’ Hall, in Phillip 
Street, has been engaged for the 7th and 8th of September, 
particulars of which have already been furnished to members by 
circular. 
The Council has again to offer its best thanks to Mr. and 
Mrs. Waterhouse, for their kindness in granting the use of their 
room in Bull’s Chambers, Moore Street, for our Council meet- 
ings.

CUP-MOTH LARVA SPINNING COCOON. 
By E. McANENE. 
Two species kept under observation during March, 1922, 
probably Limacodes longerans and Doratifera vulnerans. At 
9.20 a.m. a caterpillar of the former species placed in a hottle 
with piece of twig with leaves, some very fine silken strands 
noticed. By 9.30 appeared to be biting bark from twig, and at 
10.0 was hanging head downwards, holding firmly to twig by 
anal claspers. The head was bent over the back and moying 
rapidly attaching silken threads to twig, glass and leaves. Head 
appears partly withdrawn, body contracted and ventral surface 
always turned towards light. The caterpillar works rapidly 
round itself forming the urceolate cocoon, leaving an opening at 
the wide upper end. At 11.45 cocoon assuming the pear shape 
and opening now closed. Small ring at apex noticeable, the 
cocoon now of a whitish colour, resembling the lining mem- 
brane of a hen’s egg and the caterpillar could be faintly seen 
working round inside. By 3.30 cocoon completed, firm and as- 
suming a brown shade. ‘The method of work of the second 
species was similar, but the finished cocoon was somewhat more 
oval in shape.
