REPORT OF THE FLUTED SCALE OF THE ORANGE AND ITS 
NATURAL ENEMIES IN AUSTRALIA. 
By Albert Koebele. 
In accordance with the commission received from the Hon. Norman 
J. Colman, United States Commissioner of Agriculture, and your letter 
of July 3, 1888, I left San Francisco on August 25, and arrived at Auck- 
land, New Zealand, on September 14, where some hours were spent in get- 
ting iuformation in regard to Icerya. I visited Mr. W. Will, editor of 
the New Zealand Herald and Auckland Weekly News, who then, and 
subsequently on my later visit, gave me valuable information in regard 
to the occurrence and disappearance of Icerya in the Auckland districts, 
as well as many other points of interest in horticulture ; and also Mr. T. 
F. Cheeseman, curator of the Auckland Museum, who readily accom- 
panied me to a place full of Albizzia (Acacia) lophantha, Bentham, which 
had been about three years previously completely covered with Icerya. 
I made a careful search for specimens on these trees, yet only four full- 
grown females with large egg-sacs could be found. On one of the scales 
two rather large mites were feeding, attached to the under side ; and the 
masses of old and moldy remains of Icerya were still visible on the 
trunks of trees. 
A residence on which formerly were many orange trees was also vis- 
ited. There all of the trees had been cut down on account of the num- 
erous scales, and at the time of my visit no Icerya could be found and 
none were observed during the year as the proprietors informed me. 
No one was able to state the exact reason of the disappearance of the 
scales; some disease was the supposed cause. 
The steamer left Auckland the following day and arrived in Sydney, 
New South Wales, September 20. I remained there for four days in 
search of Icerya. On my first walk a number of them were discovered 
at the town hall premises, infesting a Pittosporum (P. undulatum), and 
the succeeding days a few more were found in one of the public parks, 
also on this Pittosporum. A large isolated acacia tree full of the scales 
was found in front of a private house in the eastern part of Sydney; 
all were full-grown females with more or less developed egg-sacs and ap-
