new Ants from Australia. 441 
O. cephalotes, Sm., as shown by the measurements of the 
head and the shape of the mandibular teeth, comes in the 
coriarius group. Below is a description of the type (Oxford) 
from Ceram :— 
8. Length (without mandibles) 11°3 mm.; length of 
mandibles 1:7 mm. 
Head as above. Mandibles broad, distinctly but irregu- 
larly denticulate along inner border (Smith says “no teeth’’),. 
apex with three teeth (vide fig. 6). Clypeus prolonged in a 
blunt point between the frontal carinze. Antennal scapes 
barely extend beyond occipital border. Occipital groove 
extends to end of antennal fosse, deepest anteriorly. 
Thorax slightly emarginate between meso- and epinotum. 
Node broad at base, narrowing gradually to the spine, which 
is rather short and thick. 
Mandibles with one or two indistinct punctures near the 
apical tooth, very faintly and irregularly striate along their 
outer half. Whole of upper surface and sides of head finely 
and regularly striate, the striz coarser in front and spread- 
ing fan-wise from the frontal carinz to the base of eyes, 
and diverging slightly on the vertex. 
Pronotum finely striate transversely, anteriorly some of 
the striz form concentric ovals (this cannot be seen from 
above, but only from the sides); mesonotum with feeble 
striz, arched anteriorly ; epinotum regularly and trans. 
versely striate. 
Node encircled with fine striz. 
Entire gaster finely and longitudinally striate, and finely 
reticulate at the base of each segment. On the first segment 
- the lateral striz encircle the basal half of the segment, so 
that this half, viewed from in front, appears to be trans- 
versely striate. 
A few outstanding hairs on pronotum and gaster, par- 
ticularly on the apical segments. Pubescence very scanty. 
Dark ferruginous, almost fuscous; mandibles, antenune, 
and legs paler, gaster darkest. 
One of the co-types from Ceram is paler. 
Podomyrma nupa, sp. n. (Fig. 7.) 
%. Length 5:5 mm. 
Dark red-brown ; femora, tibiz, and gaster dark brown. 
A few scattered yellow hairs on body, tibiz, and scapes with 
a few erect hairs. Pubescence nil. 
Head very slightly longer than broad, somewhat wider 
behind where the occiput is feebly concave, the sides slightly
