were placed in the ice-house on the steamer, and as soon as Auckland 
was reached I went to the freezing- house and there my Coccinellids were 
placed in a cool room with a temperature of 35° Fah. Having been 
informed that Iceryas had been very numerous almost a year ago at a 
gentleman’s place near Lake Togabuna, several miles out of Auckland, 
a trip was made as soon as my Lady-birds were safe, for I was very 
anxious to get at the fact as to what had destroyed the Scales around Auck- 
land, and if it were not the same insect found at Napier. I was shown” 
a couple of Acacia trees, one of which had been destroyed by the Scales, 
and a second, still living, which had many Iceryas upon it. All the 
Scales on this small tree were examined, and, with the exception of a 
small Coleopterous larva within one of the egg-masses, no enemies could 
be observed. Both these trees were growing ainong old pine trees and 
were much shaded by them, in fact so much so that no sun-loving in- 
sect like the Lady-bird would venture into them. Close by about a 
dozen orange trees were growing in an open field, and on my inquiring 
if no Scales were upon these trees, the gentleman remarked that only 
about nine months since they were full of them, but that all had disap- 
peared. These I wanted to see, and on the first tree reached, while 
yet at some distance, I could see, exposed to the sun on the upper side 
of a leaf, a black glistening spot, which was the insect looked for, the 
Australian Lady-bird. On this tree more Coccinellids than [ceryas were 
‘found. The Lady-birds, if not at rest on top of a leaf in the hot sun, 
’ were busily running or flying about. This is an interesting fact. All 
the orange trees in the open field were completely cleaned of the thou- 
sands of Scales by the Coccinellids, while closely adjoining, among the 
dark and shady pines (Pinus insignis Douglas), a large Acacia tree 
(Acacia decurrens) was destroyed by the Seales, even the adjoining 
branches of the pine trees being dead, and, as stated by the proprietor, 
from the effects of Icerya. 
As yet the scales have not been observed to my knowledge on pine 
trees in California, yet Mr. Maskell also told me of having seen pine 
trees loaded with them. I observed here also an Aspidiotus very in- 
jurious to apple trees. The following day the place visited on my 
first arrival in Auckland was examined again, but only a few large 
females could be found. The young were just hatching, and many 
eggs were still present. Mr. Cheeseman had been informed by Mr. 
Purchas and others that Icerya existed abundantly in the woods at the 
English church cemetery (Paeroa), infesting Sophora tetraptera. He 
kindly accompanied me to the place, and before long pointed out the 
tree, which is closely related to the Acacias. We soon succeeded in 
finding the scales in large numbers on a few of the trees, when a care- 
ful investigation was made and a few specimens of the small Scymnus 
fagus were found. A small hemipterous insect was present among the 
ege-masses in all stages, the young being found within them, and two 
species of small spiders had built their houses among the egg-masses
