—PYRALIDINA. 
Seven families of Pyralidina are represented in New Zealand, of which the 
two most important here, the Crambide and Scopariade, have been dis- 
cussed in former papers. Three others—the Pyralidide, Pterophoride, aud 
Hydrocampide—are given here, as well as some considerable additions to 
the Crambide. The remaining two, which are the Botydide and Musotimide, 
I have recently given a list of in the Transactions of the Entomological 
Society of London for 1884, with descriptions of the new species, in con- 
nection with a paper on Australian species of the group ; these will also be 
given here in a subsequent paper. 
The Pyralidide and Hydrocampide are each represented only by a single 
species, and neither is indigenous in the strict sense. The species of Pyra- 
- lidide is à common domestic insect introduced from Europe, and now estab- 
lished throughout most of the world ; that of Hydrocampide, is an Austra- 
lian species, and must be considered to have found its way over in recent 
times. ‘The Pterophoride contain eleven species, of which one is also 
Australian, and belongs to a genus not otherwise represented in New 
Zealand; one is closely allied to a European form, and may even prove 
identical with it; the remaining nine are all endemic. These appear to be 
all of cosmopolitan genera; an unexpected result, and rather suggesting 
the inference that the generic limitation is not yet sufficiently precise, but I 
do not at present see tangible points of difference. Australia is relatively 
poor in Pterophoride, having as yet only furnished me with the same 
number as New Zealand ; the character of the fauna shows little resem- 
blance. The tendency to partial obsolescence in the neuration of this 
family makes their study a difficult one. 
I give a table showing the comparative numbers of all the families of 
Pyralidina in New Zealand and in the European region, to show the great 
irregularity of their representation here: in Australia their relative num- 
bers are very much as in Europe :—
