SOME NEW AUSTRALIAN ANTS. 91 
9. L. 8-8:5mm. 
Colour as in 8, but no trace of metallic sheen; the antenne, however, are 
almost entirely ferruginous, and the legs more so than in the %, and the borders 
of the segments of gaster are edged with a thin but distinct greyish-white margin. 
Mandibles and clypeus as in ¥% , but the whole head is broader behind and much 
more narrowed in front, and there is an impressed line from the frontal area to 
the anterior ocellus; the occiput border is almost straight. The eyes also are more 
prominent than in the %. 
The thorax is distinctly impressed between the scutum and scutellum of meso- 
thorax; there is hardly any angle between the two surfaces of the epinotum, which, 
seen in profile, shows the upper # evenly rounded, and the lower quarter concave ; 
-seen from above the segment is broader than long, and is somewhat broader in 
front than behind. There is a distinct central longitudinal impression near the 
upper border of epinotum. The scale is much broader and flatter than in the 3, 
is slightly convex in front, and flat or concave behind; the superior border rises to 
-a feeble angle in the centre. 
Gaster elongate-oval, large, nearly as long as the rest of body. 
Sculpture and pilosity as in %.  Pubescence more abundant, 
particularly on the head, epinotum and gaster, on the latter it is most 
plentiful on the borders of the segments and beneath, giving the whole 
-segment a silvery sheen. Wings slightly infuscate, the upper with 
two closed cubital cells. 
Ea wal Ds 3-3°3 mm. 
Black, with a distinct metallic blue sheen ; antennae and legs fusco-ferruginous, 
tarsi testaceous. 
Mandibles narrow, pointed, edentate, almost straight. Clypeus broad, arched, 
the anterior border entire, feebly convex. 
Head depressed, about as broad as long, narrowing behind the eyes, which are 
large, prominent, and placed slightly in advance of the middle of the sides. Frontal 
-earinae indistinct; scape shorter than the second joint of the funiculus, and all 
the joints of the latter, except the first, longer than broad. 
Scutellum in profile high and rounded, almost overhanging the epinotum ; 
seen from above, it is narrowed and rounded behind. Base of epinotum in profile, 
rounded, the declivity, which is much shorter, is nearly vertical; epinotum seen 
from above is longer than broad, slightly narrowing and convex behind ; in the 
-centre of the base is a deep and broadimpression. Scale small, broader than long, 
convex in front and straight behind, from both aspects ; gaster small and oval. 
Mandibles shining, with a few punctures. Sculpture of rest of body similar 
to, but fainter than, that of the other sexes. 
Pilosity similar, except on scutellum and epinotum, but sparser. 
Pubescence fairly plentiful on the whole body. 
Neuration. Upper wing with one closed cubital cell. 
Nests M. and N., under stone, Victoria, in Healesville (H.B.P.). 
ncaa considers this species nearest his J. calvus, from New Cale- 
-donia. 
(12) Iridomyrmex, sp. A single 8, Yallingup to Mammoth and 
Lake Caves, under log or stone in bush, July 31st, 1914 (H.B.P.). 
This ant does not agree with any of the published descriptions of the 
genus, but in default of further material it is perhaps better to leave 
it undescribed at present.
