Init not produced as teeth, tlie })osterior angles feebly projecting at 
ilie scutelluin. SeutelJuin large, slightly broader than long,

Mesonotimi small and transverse. Epinotum broader than long, 
the dorsum and declivity united in one curve; near the bottom of 
The declivity, on each side, is a flange-like projection. Node

dorsum, which is small, the anterior border below slightly concave, 
tile angles ])roducecl outward and forward as broad, blunt, tooth- 
like projections; in pi-ofile it is as high as long, highest in the 
middle, the anteri<)r face sloping at an angle of fo]'ty-five degrees, 
llie iKisteriov face sloping at a more obtuse angle, slightly convex, 
the posterior being much shorter than the anterior face. Post-

Hab.: Western Australia, Claremont (J. Clark). 
This female is from the same colony from which the worker 
was described by (b'awley. It is very much like the worker in 
general aj)pearanee, and was only noticed when some examples 
wei‘(‘ being carded. The head is much smaller than in the worker, 
and tlie scajK's mueh shoi'ter, The nodes of the pedicle are very 
dissimilar, and the gaster considerably larger. The colour is 
iigliter, moi-e nuldish, with the clyjieus, antennae and legs testa- 
ceous; they are dark castaneous in the worker. The pilosity and 
pubescence ;n-e similai', even to the two stout hairs on tlie base 
of 1he post])etiole above. 
Altbougli its general facies are extremely like the genus 
Podomyrma, the haliits are| (piito ditferent. All the species of 
7'^odomyrma are arboreal, living iu the branches and trunks of 
trees. The [iresent species lives underground, in the roots of a 
small shrub (Leptospermum ) , growing on the coastal sandhills, 
it ap])ears to utilise the burrows of woijd-borinfif insects for its 
nest. I have not seen this ant outside of the nest during the day, 
out specimens h;ive been found late in the evening, just before 
dark. The nest generally contains a large amount of Insect 
remains.
