meeting of July 1, 1872, Mr. John Hewston, junr., * exhibited 
some limbs of Australian Acacia from San Mateo which were infested 
by a species of Coccus, and stated that the insect had not only been 
detected i in its depredations upon said tree, but also upon the orange 
“ trees." This latter reference m ay very possibly have becn to the 
Cottony Cushion-scale, and if so it is interesting, as indicating already a 
spread of some miles from Menlo Park. 
All the slight evidence possessed points to the introduction of this 
scale on Australian Acacia by Mr. George Gordon about 1868 or 1869.

“ This being ‘all ll the information to be derived from the om

Dr. A. W. Saxe, of Santa Clara, Cal., in 1877, wrote* :— 
“So far as I can ascertain, it was brought to California on some 
plants imported from Australia by the late George Gordon, of Menlo 
Park (the sugar refiner)." 
In the introduction to our annual report as Entomologist to this 
Department for 1878 we referred to the serious complaints that came 
from the Pacific coast of injury by it to orehard and ornamental trees, 
and from specimens received from Dr. Saxe (Mr. Maskell's papers 
being unknown here then) referred it to the genus Dorthesia, and 
remarked :— 
* It is an Australian insect, and has of late years been introduced on 
Australian e. into South Africa, where, as I learn from one 
corresponden Mr. Roland Trimen, curator of the South African 
Museum, it bd multiplied at a terrible rate, and become such a scourge 
as to attract the attention of the Government. It has evidently been
