134 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
Female. Length 15-16°5 mm. 
Similar to the worker but larger and more robust. 
Head more square behind, sides not so convex, occipital border more narrowly 
concave. Mandibles stronger, external border convex, teeth on apical half of 
inner border larger, obsolete on basal border except one large tooth near base 
with a small one behind it. Node oval, two-fifths broader than long, sides and 
dorsum convex, anterior and posterior faces straight. Postpetiole one and two- 
thirds times broader than long, almost oval, broadest at middle. First segment of 
gaster one-fifth broader than long. Legs long and stout. 
Male. Unknown. 
Habitat —Western Australia: Albany (type locality, Dr. H. Swale; J. Clark) ; 
Perth; Mundaring; Ludlow; Serpentine River (J. Clark). 
Described from examples collected at Albany. Crawley described 
this as a race of harderi Forel. It is not related to that species. 
Promyrmecia testaceipes sp. nov. 
Plate XV, fig. 69 
Worker. Length 10-11 mm. 
Head and gaster black, thorax and, node reddish-yellow, postpetiole more or less 
reddish-yellow, generally with a large reddish spot on each side in front ; mandibles, 
antennae and legs yellow, apex of mandibles and base of scapes brown. 
Basal half of mandibles smooth and shining, apical half with coarse oblique striae. 
Head longitudinally striate, finely and densely reticulate-punctate between the 
striae. Clypeus almost smooth, some obsolete rugae at base. Pronotum and meso- 
notum longitudinally striate, epinotum and node coarsely punctate-rugose, epinotal 
declivity transversely rugose; the whole thorax and node finely punctate between 
the striae and at bottom of punctures, postpetiole and gaster microscopically punc- 
tate. 
Hair yellow, short and erect, abundant throughout, long and stout on the under- 
side of mandibles, long and fine on clypeus and apical segments of gaster, short 
and adpressed on antennae and legs. Pubescence whitish, very fine and close lying, 
most abundant on postpetiole and gaster forming a distinct covering but not hiding 
the sculpture. 
Head one-sixth broader than long, broadest in front, sides straight or very 
feebly convex, occipital border concave, angles strongly rounded. Mandibles 
slender, as long as head, external border concave at middle, inner border furnished 
with three large teeth on the apical half, two smaller teeth between the larger 
teeth, all slightly hook-shaped, directed backwards, basal half with only faint traces 
of teeth except at base, where there are two large blunt teeth directed backwards. 
Frontal carinae longer than broad, slightly wider behind than in front, widest at 
middle. Scapes not reaching the occipital border by almost their thickness: first 
and third segments of funiculus equal in length, shorter than second, apical pointed, 
twice as long as second. Thorax twice as long as broad. Pronotum twice as broad 
as long, sides and front strongly convex, dorsum flatly convex. Mesonotum one- 
sixth broader than long, convex in all directions. Epinotum one-fourth longer 
than broad, broadly rounded in front: in profile pronotum evenly convex. Meso- 
notum higher than pronotum and epinotum, evenly convex, constriction between 
mesonotum and epinotum deep and wide. Epinotum evenly convex from base to 
foot of declivity. Node one-fifth broader than long, convex in all directions; in 
profile higher than long, top half of the anterior face and the posterior face straight,
