24 
stages, were collected, most of them in the Town Hall garden. I found 
here also feeding upon the Seales a few specimens of a small Seymnus 
in all its stages which were inclosed.* The first brood of Iceryas im 
warm and exposed places at Sydney had by this time become nearly 
grown, some of them beginning to exude cottony matter, while others 
in more secluded spots were quite small. The isolated acacia tree, so 
full of Icerya in September, had become entirely clear, nothing but a 
few old and torn egg-masses being visible. With this I finished col- 
lecting the parasites and enemies of Icerya in Australia, as from letters. 
received from Mr. Crawford, at Adelaide, dated January 11 and 12, there 
was little hope of obtaining sufficient materiai at that place for another 
consignment, nor would it have paid to search for Monophlebus in the , 
ground, as at the time they could not be found in large numbers in the 
woods. Moreover, many of their parasites had already left, while the 
Icerya still known to me at Melbourne and Sydney were not sufficient 
to make a good shipment. 
A letter received at this time from you in which you directed me to 
visit New Zealand and study Icerya there until the arrival of the next 
steamer for San Francisco, in case the exposition commission would pay 
expenses, was Shown to Hon. Frank McCoppin, who at once consented to 
my proposed trip. I therefore left Sydney on the steamer of January 23 
with some hope of clearing up the mysterious disappearance of Icerya 
in New Zealand. Arrived at Auckland on the 28th, the Scales with 
parasites and Lady-birds were repacked from tin into wooden boxes, and 
were found in excellent condition. Everything within the tin boxes had 
_the appearance of being placed there only a few hours previous. There 
was no indication of any mold. Some fresh Iceryas found in a private 
garden at Auckland, on Acacia decurrens, were inclosed as food for the 
Lady-bird larve. These latter Seales were in a small colony all close 
together ou a few small branches, and numbered about eight hundred 
specimens. No insects preying upon them were found. At the United 
States consulate a letter was found awaiting me from Mr. R. Allan 
Wight, dated October 10, 1888, in which the writer mentioned various 
localities infested with Icerya, wishing me to visit Hawke’s Bay, at 
Napier, where the Seales were still numerous, although fast disappear- 
ing, and where a good field for observation would be open. I therefore 
left Auckland on January 30, overland, the New Zealand Government, 
through our consul, having furnished me with a free pass for four 
months. On this trip not many observations could be made. 
The Cabbage Aphis was found in large numbers all over the northern 
island of New Zealand as wellasin Australia. A Coccinellid was found 
subsequently at Napier feeding upon this Aphis in large numbers. It 
is described by Mr. W. Colenso as C. nova-zealandica (Fig. 12). About 
tifty specimens of these were collected and placed in empty pill-boxes. Of 
these twenty-one were still living on my arrival at Alameda, where they 
ing to a new species of a new genus.
