illustrated articles on new commercial crops has alsobeen published, 
and has done good in directing attention to new industries suitable 
for our farming operations. The botanist has initiated a scheme 
of experiments with the principal native grasses of Australia, to 
be grown side by side under equal conditions, with many of the 
best exotic grasses that have been introduced into this Colony. 
In the Entomological Department, Mr. A. Sidney Olliff has 
made a most valuable collection of noxious and beneficial insects. 
During the past year about three hundred different insects have 
been bred in the laboratory, and many of them are now preserved 
in their several stages for future display. Apart from the species 
bred, the additions to the collection have been considerable, 
amounting to not less than the following estimate :—Coleoptera 
three thousand two hundred; Lepidoptera, nine hundred and 
thirty ; Orthoptera, fifty-nine; Neuroptera, forty-five ; Hymen- 
optera, one thousand three hundred and seventy-five ; Diptera, 
four hundred and twenty-five; Hemiptera and Homoptera, nine 
hundred ; unmounted specimens in spirits of wine, about one 
thousand three hundred ; and various microscopic preparations. 
A considerable number of notes and papers dealing with the life- 
histories and habits of various injurious and_ beneficial insects, 
have been published in the Agricultural Gazette of New South 
Wales for 1893, of which the following is a summary :—Woolly 
Aphis or American Blight (Schizoneura lanigera); Pear-tree Slug
