NOTES ON AUSTRALIAN ANTS. 
N othomyrmecia macrops, sp. nov. 
(Text fig. 1.) 
Worker. — Length, 9.7-11 mm. 
Testaceous, basal half of first segment of gaster darker. Mandibles, 
clypeus, antennae and legs pale yellow. 
Mandibles very finely and densely punctate, with a row of large punctures 
along inner border at base of teeth. Clypeus and head very finely and super- 
ficially reticulate. Pronotuin finely rugose, the rugae forming feeble trans- 
versely arched ridges. Mesonotum finely reticulate with a few large shallow 
punctures. Epinotum transversely and finely rugose. Node smooth in front, 
finely reticulate and with a few large punctures behind. Postpetiole gaster, 
antennae and legs microscopically punctate. 
Hair yellow, erect, moderately long and abundant throughout, shorter 
and suberect on antennae and legs. Pubescence white, very fine and adpressed, 
abundant throughout but not hiding the sculpture. 
Head as long as broad, much broader behind than in front, broadest just 
behind the eyes, sides convex, occipital border strongly concave, angles strongly 
rounded. Mandibles shorter than head, external borders straight to apical 
third then rounded inward and downward ; inner border straight to basal 
fourth then abruptly reduced to base, furnished with ten or twelve small 
sharp teeth, about equally spaced along the edge, with minute denticles 
between them, basal angle sharp, apex long and pointed. Clypeus feebly 
convex above, produced and convex in front. Frontal carinae erect, almost 
parallel, extending backward level with middle of eyes, not covering the 
antennal insertions in front. Eyes large and convex, placed at middle of sides 
slightly on top, occupying full}' one-third of sides. No ocelli. Scapes extend- 
ing beyond occipital border by one-fifth their length, slightly thickened toward 
the apex ; second segment of funiculus one-fourth longer than first, third and 
fourth, these equal in length, fifth to tenth becoming gradually shorter, apical 
as long as the two preceding together. Thorax two and three-quarters times 
longer than broad. Pronotuin slightly broader than long, strongly convex in 
all directions. Mesonotum almost as long as broad, almost circular, strongly 
convex transversely. Epinotum longer than broad, convex in all directions ; 
in profile the dorsum and declivity strongly convex without traces of a boundary. 
Node slightly broader than long, bluntly pointed in front, convex in all direc- 
tions ; in profile longer than high, dome shaped but slightly higher in front 
than behind, one-third longer than the stalk in front ; ventral surface with a 
long broad bluntly pointed tooth in front directed downward. No traces of a 
constriction between the postpetiole and gaster. Postpetiole twice as broad 
as long, bell-shaped ; ventral surface with a long sharp, hook-shaped, semi- 
transparent tooth directed backward. First segment of gaster one-third 
broader than long, broader behind than in front, sides strongly convex. Sting 
very long and stout. Legs robust. 
Habitat — -Western Australia, Russell Range (Miss A. E. Baesjou). 
Described from two examples captured by Miss Baesjou 
near the Russell Range, inland from Israelite Bay. 
This remarkable ant is not closely related to any other known 
to me. The long broad jaws with very fine sharp teeth, meeting
