and finally cleared in clove oil. They were then mounted in the usual way in Canada 
balsam. Some good results were obtained by this method. A further batch of specimens 
was macerated in caustic potash, until all the parts had been removed except the cuticle. 
The latter was then carefully washed, and treated in the same way as the entire insects 
of the first batch. This method gives excellent results in the study of the ocelli and 
other minute organs in the larve of Neuroptera, but it yielded only poor results with 
these Collembola, in which the cuticle was much more delicate. Finally, a third batch 
of specimens was taken and treated with a weak solution of calcium hypochlorite, the 
bleaching being expedited by the addition of a drop or two of weak hydrochloric acid. 
The bleached specimens were then allowed to dry off slowly, and were examined in situ. 
By this method the grouping of the ocelli became visible, together with the post-antennal 
organ, when present. 
SPECIES ALREADY DESCRIBED FROM MACQUARIE ISLAND. 
Although Macquarie Island has been visited by several scientific expeditions, 
very few insects appear to have been collected there, or, at any rate, few have been 
described. In November, 1907, the New Zealand Government steamer ““ Hinemoa”’ 
visited the Auckland and Campbell Islands, and landed scientific parties on both groups, 
Macquarie Island does not seem to have been visited; but, in the excellent publication 
subsequently issued by the New Zealand Government, entitled “The Sub-antarctic 
Islands of New Zealand,” and based mainly upon the results obtained by these parties 
of scientists, the authors who have dealt with the various Orders of Insects have included 
a few from Macquarie Island, so as to make the survey approach as nearly as possible 
in extent to the demand implied in the title of the book. Thus this publication, issued 
in 1909, includes all the insects known from the sub-antarctic islands of New Zealand 
up to that time; and I am not able to trace any new species described from them since. 
It is necessary to take into account the insects described from all these islands; for, 
although Macquarie Island lies almost twice as far to the south of New Zealand as 
do the other groups, yet the possibility of some of the same, or very closely allied, 
species occurring there is very considerable. 
In Vol. I of the above-named publication, the following species are described 
from Macquarie Island :-— 
Order: COLLEMBOLA. 
Family: Popuripé.
