THE AUSTRALIAN NATURALIST. 77 
ject would be sadly incomplete without even a passing 
reference to our ‘“‘Mulga Secrubs,’’ Acacia aneura, F.v.M., 
which rank as the greatest stand-by of the fodder bushes. 
There are four kinds distinguished by their leaves, as 
“Liong-broad,’’ ‘‘Long-narrow,’’ ‘‘Short-broad,’’ and 
“‘Short-narrow’’ leafed. The habits of growth between 
the narrow and broad kinds are somewhat different; but 
other things being equal, the passing of these kinds into 
each other by such subtle gradations, renders their separa- 
tion, even into distinct varieties, not to say species, a mat- 
ter of impossibility from a Botanical point of view. They 
have spikes of yellow flowers of the Mimosae forms, and 
about one-half to an inch long. The narrow-leafed forms 
are especially responsible for the formation of ‘‘Mulga 
Balls;’’ caused by the sheep eating the indigestible twigs 
and bark, which gather up into aseries of balls of the size 
of a tea-cup in the podges of the sheep. Unfortunately, this 
valuable fodder shrub is being killed out in large patches 
on account of being infected with a gall, caused by a rust 
known as Uromycladium Teppert, McAlpine. The wood of 
the Mulga is very attractive when worked up, especially 
in ornamental turnery, showing a pretty contrast between 
the dark brown xlyem and the creamy phloem. It has also 
the benefit of a scented odour. ;

LIFE-HISTORY OF TEIA ANARTOIDES. 
By L. Gallard. 
This moth is common on the wattle about Sydney, and 
was described in the Agricultural Gazette, N.S.W., as an- 
apple pest; also in Froggatt’s Australian Insects, p. 255. 
The specimens described were bred from Quince trees. 
Larva, brown, with brush-like tufts of hair on the 
back, and two tufts sticking up on the sides of the head. 
The larvae, when feeding, draw the foliage together 
slightly with a silken web, forming a shelter in which, 
when fully developed, they pupate. The female is wing- 
less, and, on emerging from her thin silken cocoon, she
