CHIRAGA SPLENDENS. A mounted specimen of the female, 
which is about two inches aeross the expanded wings. The 
body and hind wings are salmon coloured, and the front pair ~ 
are a mixture of green and dark salmon, showing a nice pattern. 
A larva and pupa were exhibited in spirits. The pupa was of 
the male sex, which when fully matured is a lovely green 
moth with a wing expanse of about 14 inches. In this ease the 
fore wings are ornamented with two bright silver bars, which 
form a great contrast in colours. These white bars could be 
seen very distinctly on the wing pads of the pupa exhibited. 
Euploea corinna. Two pupae in spirits.’ In this ease the 
metallic tints were beautiful, as the spirits seemed to bring out 
all the bright sheens characteristic of this family. 
ACACIA ELONGATA. I have a plant of this wattle in my 
garden which has been literally covered with bloom for the past 
two seasons, and which has not set any seed as yet, but to my 
surprise I find that it is spreading by means of underground 
stems. ‘There are now three young plants about two yards from 
the parent, and which show the pinnate leaves just as a seedling 
would. We know that certain acacias have this habit, notably 
Mr. Cheel’s A. intertexta which travels for long distances. A. 
melanoxylon, dealbata, pubescens and probably others do, and I 
think this is worthy of record. A. elongata is well worthy of 
cultivation. ;

Aboriginal implements.—At Boat-Harbour, at north end of 
Cronulla Beach, I found a great mound of broken shells left by 
the aborigines. Near by is a fresh water spring. Strewn 
about were numerous stones used to erack shells, amongst which 
were two good hasalt axes and one implement evidently an- awl, 
two flat stones for grinding mills and numerous flakes of basalt 
and quartz. KE. L. Hayes. 
Eucalyptus in Brazil.—In connection with the establish- 
ment of a large electric steel plant in Brazil, the Jour. Soe. 
Chem. Ind. XLI., March 15, 1922, p. 102 R., states that Brazilian 
charcoal is to be used and that eucalyptus forests are to be 
planted to supply fuel. 
This seems to be looking a long way ahead, it does not ap- 
pear by any means clear whyeucalyptus should be preferrable 
to the native timbers for such a purpose. The planting would 
require to be on a very large scale. Ed. A.N.
