APPENDIX. 
INSECTS AND TIMBER TREES, 
PART I. 
I would like to invite the attention of my readers to the fact that little has been 
done to bring together, in a comprehensive manner, the facts concerning the relations 
between insects and particular groups of trees in Australia. If we take the most 
economically important of our trees the Eucalypts, we find the information much 
scattered and not readily available to the non-entomologist. 
A long series of very valuable articles entitled " Insects injurious to our native 
Eucalypti," by 0. A. Wilson, will be found in the weekly, " The Farm and Garden" 
(Adelaide), Vol. I (1858-9) to Vol. V (1862-3). 
As a very general rule, particularly in Entomology, if a zoological writer mentions 
Eucalyptus in connection with a species, I note it, but if he does not mention that genus 
I am ignorant that Eucalyptus is implied, and so what I have written is bound to be 
incomplete for that reason alone. I am further quite aware that it is perfectly impossible, 
and would serve no practical purpose, to enumerate all the insects which, at one time 
or another, are captured on Eucalyptus, but it is only an Entomologist who can make 
the necessary discrimination. 
Our Government Entomologist (Mr. W. W. Froggatt) has written brief mono- 
graphs on Insects and Wattles, Insects and the Kurrajong, &c. (Agric. Gazette, N.S.W.), 
which whet our appetite for more. 
The work of bringing together the notes and papers on Insects and Eucalypts 
is so great that I could not ask one of our overworked entomologists to undertake it, 
and so I attempted to make a beginning myself; and my little effort is offered quite 
apologetically, by one who is quite ignorant of entomology, in the hope that it may 
be suggestive, and that it may lead, sooner or later, to the idea being developed by an 
entomologist, with suitable illustrations. 
[ am aware that the compilation of complete lists of insects found on our 
Eucalypts (many of them, alas! pests) would be too voluminous, and would not meet 
the present need. My treatment of the subject is a compromise. 
I am sure my entomological friends will pardon me if I point out that their work 
have enhanced value if additional pains be taken to apply to botanists for the 
names of the plants concerned. To merely say that an insect was taken on " Eucalyptus 
sp." -for example, is regrettable if it can be avoided. 
The arrangement of the families of insects follows, as far as possible, that of 
Mr. Froggatt' s " Australian Insects."
