96 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
petiole barely one and one-half times broader than long, hemispherical in front ; 
constriction wide but not deep. First segment of gaster one-fifth broader than 
long. Legs short and robust. 
Female. Length 14-16 mm. } on 
Larger and more robust than the worker, colour identical, sculpture similar but 
coarser; pilosity longer and more abundant. Scutellum small, feebly impressed, 
about one-fifth of the length of mesonotum. 
Habitat—New South Wales: Tarcutta; Gundagai (J. Clark) ; Canberra (G. F. 
Hill, T. Greaves) ; Red Hill (T. Greaves) ; Monaro (N. R. Flynn).

Worker. Length 11-12 mm, 
Dark red; postpetiole and gaster black; front of face and the legs brownish- 
black; mandibles, antennae and tarsi yellow. 
Shining. Head longitudinally striate-reticulate, the striae straight on middle of 
head, slightly diverging outward at sides, and continued into the antennal depres- 
sions. Some large punctures on occipital border. Mandibles strongly and obliquely 
striate. Pronotum longitudinally and strongly striate. Mesonotum and epinotum 
transversely striate, continued obliquely on the sides. Node coarsely reticulate. 
Postpetiole and gaster very finely punctate. 
Hair yellowish, erect, rather sparse throughout. Pubescence greyish, very fine 
and adpressed, most abundant on postpetiole and gaster. 
Head broader than long, as broad in front as behind, occipital border concave, 
posterior angles rounded. Mandibles short and broad, external border concave at 
middle; inner border nearly straight to basal third, furnished with eleven teeth, 
the first two small, the third, fifth, ninth and tenth large and blunt; the ninth 
forms the angle between the two apparent borders. Frontal carinae erect, nearly 
straight, extending to posterior margin of eyes. Scapes not extending to occipital 
border by one-fifth of their length; first segment of funiculus as long as second. 
Thorax fully twice as long as broad; pronotum twice as broad as long, broader in 
front than behind, dorsum flattened in middle. Mesonotum slightly broader than 
long, convex and rounded above. Epinotum one and three-fourths times longer 
than broad, strongly arched from basal to inferior posterior edge; the declivity 
not defined. Node as broad as long, broader behind than in front, in profile higher 
than long, rounded above, the stalk in front extremely short. Postpetiole one and 
one-third times broader than long. First segment of gaster slightly broader than 
long, almost as broad behind as in front, sides convex. Legs moderately long and 
stout, 
Male and female unknown. 
Habitat —New South Wales: Manilla (W. W. Froggatt) ; Quirindi (Col. C. V. 
Morissett). 
Re-described from a co-type received from the late Mr. W. W. 
Froggatt. : 
This is close to P. aberrans, as noted by Forel, but is distinct.
