SOME NEW AUSTRALIAN ANTS, 89 
Antennae long, the scape much shorter than the second joint of funiculus, all 
the joints of which, except the second, are much longer than broad. 
Head longer than broad, widest behind the eyes, the occipital border feebly 
concave. 
Thorax ; Mayrian furrows deeply impressed ; the declivity of epinotum longer 
than the base, with a faint raised border surrounding it; a slight angle separates 
the two surfaces. 
Petiole, from above, is longer than wide; in profile, it is surmounted behind 
with a rounded node, and beneath anteriorly bears a pointed process. 
Gaster elongate, with a distinct constriction between the first and second 
segments. 
Mandibles densely and finely striate, with a few elongate punctures. Clypeus 
longitudinally rugose, with a fundamental fine reticulation. Mesonotum coarsely 
reticulate between the Mayrian furrows; this reticulation extends beyond the 
furrows and merges into a fine longitudinal striation. 
Scutellun: longitudinally rugose-striate; base of epinotum coarsely rugose 
transversely, the declivity more finely so. Node transversely rugose. 
First segment of gaster finely striate transversely on the anterior portion, the 
centre of the base (in one specimen) having longitudinal striae (absent in the other 
specimen) ; the remaining segments microscopically striate transversely. 
The whole body with plentiful long reddish erect hairs, the tibiae with erect 
hairs. Anterior legs and gaster with a fine grey pubescence. 
Two specimens (Nest R.) taken in nest with %s, Aug. 23rd, 1914, 
Blue Mountains, N.S8.W., near Mt. Victoria, by Prof. Poulton.

Sub-fam.: Myruiciw2. 
(10) Meranoplus minor, sp. nov. § 
L, 2°7-2:8mm. 
Castaneous; gaster palest, clubs of antenne, vertex and nodes, darkest. Ter- 
minal border of mandibles edged with dark brown. 
Mandibles quadridentate. Frontal area triangular, in some specimens very 
indistinct. Clypeus bidentate, not deeply emarginate between the teeth. 
Head square, upper surface regularly convex, sides parallel, occiput hardly con- 
cave ; scapes swollen towards the apex ; posterior halves of frontal carine parallel, 
anterior halves curving inwards and forming a blunt projection on each side of the 
clypeus; the scrobes extend about an eye’s width beyond the eyes. 
Pro-mesonotum wider than long, terminated in front by two flat triangular 
teeth, each lateral border has a broad shallow excision in front, and two deep 
circular ones behind, the posterior angles terminating in two long blunt teeth 
which curve inwards; the sides are in addition furnished with flat transparent 
plates, subparallel, which cover the excisions. The posterior border of mesonotum, 
which is broadly concave, has a wide and shallow excision in the centre, which is 
also covered with a membranous plate. Epinotum vertical, with two straight 
spines in the middle of the sides, the spines are directed outwards, and are shorter 
than the interval between their bases. 
The first node of the pedicel wedge-shaped, its superior border horizontal ; 
second node, seen from above, feebly convex in front, and strongly so, almost angu- 
lar behind ; in profile regularly convex from below to the apex, and concaye behind, 
forming a slight overhanging lip. 
Gaster broad and pointed, emarginate at base. 
Mandibles striate; clypeus superficially coriaceous, with two or three broken 
longitudinal ridges. The-upper surface of head with longitudinal parallel ridges,
