The agents concerned in the production of galls are enumerated as follows in 
Connold's~work (British Vegetable Galls) :- 
1. Acarina or Mites. 
2. Anguillula or Eel-worms. 
3. Coleoptera or Beetles. 
4. Diptera or Flies with two wings. 
5. Fungi. 
6. Hemiptera-Homoptera or Aphides. 
7. Heterocera or Moths. 
8. Hymenoptera or Wasps (small). 
Numbers 1, 2, 5, do not, of course, refer to insects. 
But collections and notes on vegetable galls are required in Australia, Very 
few are engaged in the work. Will any one help? 
" The Growth of Vegetable Galls," W. W. Froggatt (Agric. Gaz. N.S.W., April 
and May, 1898), is a popular account of galls, together with a list of the principal galls 
interesting to us in Australia, and is a charming introduction for a beginner. 
ORDER II (ORTHOPTERA). 
Family Termitidse (White Ants.) 
In the year 1894, when Curator of the Technological Museum, I arranged with 
Mr. Froggatt, then Custodian of the Economic Zoology in that institution, and now 
Government Entomologist, to issue the enclosed circular, and I reproduce it because 
we still have so much to learn in regard to the relative powers of resistance of the various 
Eucalyptus timbers. We know, for example, that White Ants find the Ironbarks of New 
South Wales and Queensland (our most esteemed timbers) especially palatable, but we 
know very little of the White Ant question from the botanical side. I hope that steps 
will be taken to fill up that hiatus in our knowledge, which I hope may have some 
classificatory value in regard to species. 
I am describing the Tennitidse of Australia, better known as " White Ants," a group of insects of 
whirh very little is known and whose destructive habits give them great economic interest. T forward this 
to you in the hope that if you cannot help me, in obtaining specimens from your district you will pass it on 
to someone who can. 
The following notes will be a guide to collectors : 
(1) The white ants should be collected from their nest, or wood they are infesting. Workers and 
soldiers can always be found, but the Queen, which is generally found in the centre at the bottom of the 
nest, is of great value in determining the species ; she resembles a white grub with an ant's head, and is 
often as thick and as large as one's finger. The winged forms of the young Queens or males are only found 
in the nest at certain seasons, but should always be sent when found. Thus there are five sorts of ants in 
each nest.
