142 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
Myrmecia (Promyrmecia) piliventris Smith s.sp. rectidens Wheeler, Colony- 
founding among Ants, p. 68, 1933. 
Worker. Length 9:5 mm. 
Mandibles, antennae and legs reddish-brown, head, thorax and node brownish- 
black, postpetiole and gaster brown. 
Shining. Mandibles with a few coarse striae on apical third, almost smooth 
behind, a few shallow elongate punctures. Head finely striate longitudinally. 
Pronotum and mesonotum longitudinally striate, much coarser than on head. 
Epinotum coarsely rugose, longitudinal on anterior fourth, irregular behind, trans- 
verse on declivity. Node coarsely and irregularly rugose, postpetiole and gaster 
microscopically punctate. 
Hair yellow, short and erect, sparse throughout, long and more numerous on 
clypeus, mandibles and apical segments of gaster, short and suberect on scapes and 
legs, longer at apex of femur. Pubescence not apparent except on postpetiole and 
gaster, where it forms a dense golden covering hiding the sculpture. 
Head almost as long as broad, sides feebly convex, occipital border feebly con- 
cave, angles broadly rounded. Mandibles fully their width longer than head, 
straight and parallel, bent at basal fourth, inner border furnished with five large, 
sharp, erect teeth slightly inclined backward; behind these is a series of very small 
backward-directed denticles. Scapes extend to occipital border, first and third 
segments of funiculus equal in length, fully half as long as second. Thorax fully 
twice as long as broad. Pronotum almost twice as broad as long, dorsum flattened. 
Mesonotum as long as pronotum, one-fourth broader than long, meso-epinotal 
constriction deep and narrow. Epinotum one-fifth longer than broad, dorsum 
feebly convex ; in profile mesonotum raised above level of pronotum and epinotum, 
excision deep and narrow; pronotum evenly convex from apex to base; mesonotum 
highest in front, evenly convex; epinotum evenly convex from base to foot of 
declivity. Node as long as broad, anterior and posterior faces straight, vertical, 
rounded into the feebly convex dorsum, ventral spine long and thin, not as long 
as wide at base. Postpetiole one and three-fourths times broader than long, strongly 
convex, constriction wide but not deep. First segment of gaster one-fifth broader 
than long. Legs slender. 
Male and female unknown. 
Habitat—New South Wales: ? Kingstown (W. W. Froggatt) ; Uralla (W. W. 
Froggatt). 
Victoria: Ararat (G. F. Hill). 
Re-described from a co-type received some years ago from Mr. 
Froggatt. The locality label on the co-type states King’s Sound 
142 in Froggatt’s writing. This is undoubtedly an error as this 
form is found plentiful around Kingstown and Uralla in New 
South Wales. Forel gives the locality as Kingstown, Australia

This form differs from piliventris only in the colour of the coxae and femora, 
red on some examples. Many specimens from the same nests cannot be separated
