Tlie imllviduality of the Ant Fauna of South West Australia 
is pronounced, as previously noted by Prof. A- Forel. * Most of 
the species known at that time had been described by him, from 
material collected by visiting naturalists. 
Until recent years little collecting had been done by local 
naturalists, but the collections so mad(' teml to show tUtl we have 
I'epresentatives of various groups which exhibit a rathei- intei'esting 
distribution. 
In the following pages three new species, and the female of 
a recently described species, are recorded from South West 
Australia, and one new species from New South Wales, 
The most important of these is a species of Discothyrea^ a 
genus not previously found iji Australia. This genus has a wide 
distribution, members of it are found in Africa, America, New 
Zealand, New’' Guinea and Java. The occurrence of this species 
in South West Australia is of ])articular interest. 
The genus Acanthoponcra is at present represented in Australia 
bv one species and one variety; these have been recorded from 
t^ueensland and South Australia. I have now to record a new' 
species from the South West of this State. This genus w’as 
originally descilbed from South America, but has also been found 
in New Zealand. 
The genus Pscudopodomyrma was recmitly described by 
Orawdey. He noted the general i-esemblance of the workers to 
those of the genus Podoinynna. While the Avorkers are similar 
in general appearance the females are very different, as Avill l>e 
seen from the following description and figures. 
The remaining species belong to genera which have already 
been dealt wdth by me in the Journal of tMs Society. 
The types of the new species are at present in the author’s 
collection.
