these were sent to this State and from them a few specimens of the 
parasite were bred and liberated. 
A parasite of the red scale—a tiny chalcid wasp—has now 
established itself strongly in Calfornia, and also in Western 
Australia, where it was concurrently introduced from the same 
source. In February and March, 1906, swarms were found in scale- 
infested gardens in West Perth, and also near Kalamunda at Mr. 
Greedy Scale.

Palmeteer’s orchard, where a few specimens of the helpful parasite 
had been liberated. Since then they have been widely distributed 
by the Entomologist, Mr. J. L. Newman, and the Fruit Industries 
Branch of the Department of Agriculture, with most satisfactory 
results. Orange and lemon trees which some 10 to 15 years ago were 
fumigated every two or three years are now left severely alone, 
and are all the cleaner for not being interfered with, as it was 
found that fumigation was fairly efficacious but, when strong 
enough, destroyed along with the scale insects the young bud- 
carrying shoots, thereby throwing the trees back one season and 
causing the loss of one year’s crop.
