ANTS FROM THE OTWAY RANGES. 
Head slightly longer than broad, sides straight to posterior third, from 
there reduced and convex behind. Occipital border deeply excised in the 
middle, forming two strongly rounded angles. Mandibles edentate, with a 
distinct notch near apex, large and triangular. Clypeus short, produced in 
front, with a semi-circular excision in the middle, the sides forming sharp 
teeth-like angles. Frontal carinae short and broad, overhanging the antennal 
insertions. Scapes short, not extending to middle of head ; first segment of 
funiculus as long as the four following together, second to eighth broader than 
long, ninth and tenth longer than broad, apical two and a half times longer 
than broad and longer than the three preceding together. Eyes small, feebly 
convex, situated at anterior fourth of sides. Pronotum and mesonotum 
together as broad as long, almost circular. Epinotum one-third longer than 
broad, sides parallel, furnished behind with two long slender spines directed 
upward and backward. In profile the pronotum and mesonotum united in a 
large dome-shaped convexity ; epinotum straight, declivity short, forming a 
right angle with dorsum, the spines sharply pointed. Node sharply pointed 
above, concave in the middle ; in profile one-fourth longer than high, the 
anterior face descending at an oblique angle ; feebly concave. Postpetiole 
twice as broad as long, oval ; in profile dome-shaped. First segment of gaster 
almost one- third broader than long, sides and front strongly convex. Legs 
short and robust. Femora greatly thickened at the middle. 
Worker minor. — Length, 2-2.5 mm. 
Chestnut-brown ; antennae and legs lighter. 
Sculpture as in worker major, but slightly coarser and mandibles striate. 
Pilosity similar. 
Head as long as broad, sides and occipital border convex. Mandibles 
furnished with six or seven sharp teeth behind the apex. Clypeus produced, 
anterior border straight or very feebly concave. Frontal carinae longer, more 
lobe-like in front. Scapes reaching the occipital border ; funiculus as in worker 
major. Eyes convex, situated in front of the middle of sides. Thorax as in 
worker major. Node a little more slender, dorsum convex. The remainder 
as in the major. 
Habitat. — Gellibrand. 
A nest under a log. Near P. ampla For el but readily- 
separated by the shape of epinotum, spines and nodes, as well 
as by the strongly marked sculpturing.

Worker . — Length, 2.7 mm. 
Bright ferruginous ; apex of first segment of gaster and middle segments 
of funiculus infuscated ; apex of antennae, scapes and legs ochraceous.
