ANTS FROM THE OTWAY RANGES. 
rounded. Frontal carinae erect, confluent, truncate behind. Carinae of 
cheeks sharply marked, almost meeting frontal carinae behind. Scapes 
greatly thickened to apex, extending to posterior third of head ; first segment 
of funiculus slightly longer than broad, second to ninth broader than long, 
apical two and a half times longer than broad and as long as the four preceding 
together. No trace of eyes. Thorax twice as long as broad, constricted at 
the mesonotal area, feeble traces of sutures. The lateral and anterior borders 
rounded, posterior border straight, margined, the angles tooth-like. In profile 
feebly convex longitudinally, with a slight depression indicating the meso- 
epinotal suture ; cpinotal declivity short and concave, flat laterally, sub- 
margined on sides. Node very slightly broader than long, slightly broader 
behind than in front, anterior and posterior borders straight, sides convex ; 
in profile longer than high, dome-shaped ; a long, broad, sharp-pointed pro- 
jection in front below. Postpetiole almost one-fourth broader than long, 
broader behind than in front, sides and anterior border straight ; a deep 
and wide constriction between it and first segment of gaster. All segments 
of gaster separated by deep constructions. Pygidium broad and flat, bordered 
in front with short sharp bristles, becoming obsolete behind. Legs long and 
slender. 
Female. — Length, 3. 8-4. 2 mm. 
Colour, sculpture and pilosity as in the worker. Head as broad as long, 
sides strongly convex. Eyes large, convex, situated slightly in front of middle 
of sides. Ocelli large. Mandibles more strongly denticulate. Thoracic 
sutures more strongly marked. Gaster much larger than that of the worker, 
the segments more widely separated. Pygidium larger and the bristles at 
sides longer and stronger. 
Habitat. — Gellibrand, under stone, and one female under log. 
Near E. hirsutus Clark, but more robust and more strongly 
sculptured. 
Subfamily Ponerinae Lepeletier 1836. 
Genus MYRMECIA Fabricius 1804. 
Myrmecia crassinoda, sp. nov. 
(PI. IV, fig. 2.) 
Worker . — Length, 16-20 mm. 
Dark red, almost brown ; gaster black ; middle of forehead between 
frontal carinae and ocelli black, size of area varying in individuals ; mandibles 
and clypeus castaneous ; antennae, anterior legs and all tarsi ferruginous ; 
middle and posterior femora and tibia brown. 
Mandibles, postpetiole and gaster shining. Head strongly striate diverging 
outward behind. Pronotum longitudinally arched striate, transversely on a 
few examples. Mesonotum and epinotum transversely striate. Node circularly 
rugose. 
Hair yellowish, long and erect, abundant throughout, short and suberect 
on legs. Pubescence yellow, very fine and adpressed, longer and coarser on 
clypeus and apical segments of gaster than elsewhere.
