Insects -- Australia
The typical species (Genus _Urania_) are found in America, others in
Madagascar; but our beautiful forms belong to the Genus _Nyctalemon_,
one species of which, _Nyctalemon orontes_, is very common in North
Queensland. In the neighbourhood of Cairns a score of this species can
often be taken in the early morning resting on the low scrub, and small
swarms of them can often be seen flying across the rivers in the middle
of the day. This species is a very handsome large velvety black moth
marked with broad dull green bands, and having short creamy swallow
tails. Several very beautiful species are also found in Southern New
Guinea.
Family 3. Day Moths.
AGARISTIDAE.
This family has been lately revised by Hampson (Catalogue of the
Lepidoptera Phalaenae Vol. I. British Museum 1898); he divides them
into 55 Genera containing 225 species, of which some typical forms are
peculiar to Australia; they are conspicuously coloured and further
noticeable from their habit of flying in the daytime. The members of
this family are chiefly confined to the tropical parts of the Old World
and the Australian region; in America a few only are found in Mexico
and Brazil.

The Caterpillar and Adult of the Vine Moth.
(“Agricultural Gazette,” N.S.W.)]
The Vine Moth, _Phalaenoides (Agarista) glycinae_, better known under
the old generic name of _Agarista_, is one of our regular vine pests
in the caterpillar state, devouring the foliage and young grapes.
The moth lays her eggs upon the vine canes; the grubs when full grown
measure up to 2 inches; are of a general deep greenish yellow tint,
with the whole of the upper surface covered with small tubercles each
bearing a single hair; and they have a band of bright red blotches
round the dorsal surface of the anal segment. They bury themselves
in the ground, forming a dark reddish brown chrysalid enclosed in a
primitive cocoon or covering of particles of earth. The moth measures
2¼ inches across the wings, and is of a uniform black colour marbled
on the head, thorax, and sides of the wings with white; the fore wings
are tipped with white, and an irregular transverse bar of pale yellow
is followed by a smaller blotch through the centre; in the hind pair
the outer margins are irregularly edged with white. _Phalaenoides
tristifica_, formerly known under the name of _Agarista lewinii_, is
slightly smaller; the fore wings are more mottled, and the hind pair
have an irregular white spot in the centre by which it can be easily
identified. _Cruria donovani_, also smaller than the Vine Moth, has
the fore wings mottled with a number of small white blotches, and a
broad irregular patch in the centre of the hind ones. _Eutrichopidia
latina_ comes closer still to the Vine Moth in size and colour, but
can also be easily recognised by having a single broader, irregular,
