Eubothroponera bicolor  HNS  , n. sp. (Text-fig. 1, Nos. 8, 80.)

Worker.-Length, 4-8-5-3 mm.

Red. Head and gaster brown, mandibles, clypeus, antennae and legs reddish brown.

Shining. Head, thorax and node finely and densely punctate, the punctures on the thorax a little larger than those on the head, some large shallow punctures scattered sparingly throughout. Gaster densely, microscopically punctate.

Hair yellow, short and suberect, very sparse throughout. Pubescence fine, short and adpressed, particularly on the antennae and legs.

Head slightly longer than broad, the occipital border and sides convex. Frontal carinae overhanging the antennal insertions. Clypeus strongly convex above, the anterior border strongly produced. Eyes convex, placed at the middle of the sides. Scapes extending beyond the occipital border by one-fourth of their length; first segment of the funiculus slightly longer than the second, the others subequal. Mandibles triangular, abruptly bent at their base, edentate. Thorax one and three-f ourth times longer than broad. Pronotum fully one and two-third times broader than long, convex in front and on the sides. Mesonotum and epinotum united without traces of a suture, convex laterally, the posterior border not margined; in profile convex longitudinally, the declivity at an obtuse angle, the boundary between the two faces hardly defined. Node one-fourth broader than. long, broader behind than in front, the anterior border straight, sides convex, the posterior border straight and submargined, with traces of a tooth in the middle. Gaster distinctly constricted between the first and second segments. Legs long and slender.

Habitat.-Western Australia: Ludlow (J. Clark).

Several specimens taken on tree trunks. No nest has been found. This species comes near E. micans  HNS  , but. can be distinguished by the form of the head and node, also by the colour, sculpture and pilosity.
