small numbers; this is C. tasmanii(Fig. 13). The Cabbage Plutella {Plu- 
tella cruciferarum Zell.) was here as well as all over Australia, observed 
to be very abundant. Mr. French, of Melbourne, had a specimen on exhi- 
bition with the name of "Plmia crucifera" as injurious to cabbage. The 
small Tineid, so destructive to potatoes in California, aud no doubt 
already distributed over the most of the Western States, has been known 
in New Zealand for years, aud it is doing the same mischief all over 
Australia, where it originated. In conversation with a merchant from 
Denver, Colo., recently, he said that a year ago he received three car- 
loads of California potatoes, infested with these worms to such a de- 
gree that they could not be sold. I also met here, wherever apples are 
grown, with what is probably Mytilaspis pomorum Bouche, the species 
previously referred to as such.

Mr. A. Hamilton, curator of the museum at Napier, who had been 
informed by Mr. Wight of my intended trip, awaited me and at once 
showed me a number of infested Acacia trees. Icerya was here still in 
countless numbers. Before breakfast the next morning this gentleman 
showed me one of the Australian Lady-birds,* saying that he found it 
among Icerya. On investigation they were found in large numbers in 
every place visited at Napier aud several miles out in the country. I 
left Napier for Wellington on the llth to visit Mr. Maskell. This gen- 
tleman had never had the opportunity of studying the enemies of Icerya, 
as the scales are not found anywhere within 80 miles of Wellington. It 
had been the firm belief of some persons in New Zealand that certain 
Ichneumonids were the destroyers of the Scales. I saw dozens of sev- 
eral species of these upon one orange tree infested with Icerya near 
Napier, not injuring them in any way, but devouring the sweet exuda- 
tion from them. Larger numbers of flies were present than Ichneu- 
nionidre, and even Crambidae were engaged in the same perform- 
ance, yet these received no share in the compliments. Mr. Maskell had 
received from the Cape of Good Hope about two hundred specimens 
of several species of Coccinellids, which, as the sender informed him,
