Myrmecia (Myrmecia) harderi Emery, Gen. Insect., fasc. 118, p. 21, 
1911, &. 
Worker. Length 10-5 mm. 
Head and gaster black, mandibles yellow, antennae and tarsi reddish-yelow. 
Legs, coxae and base of mesosternum brown, thorax, node and centre of post- 
petiole yellowish-red. 
Mandibles smooth and shining on basal half, coarsely striate on apical half. 
Head very finely striate longitudinally, finely reticulate between the striae. Meso- 
notum feebly and irregularly rugose, the rugae almost longitudinal, densely reticu- 
late. Epinotum and node much more coarsely and irregularly rugose. Postpetiole 
longitudinally striate-rugose. Gaster microscopically punctate. 
Hair yellow, short and erect on head, thorax and legs, longer and more abundant 
on node, postpetiole and gaster. Pubescence white, very fine and adpressed, much 
longer and more abundant on gaster but not hiding the sculpture. 
Head very slightly broader than long, occipital border feebly concave, sides 
convex. Mandibles as long as head, slender, parallel, external border concave, inner 
border furnished with five large, short, erect teeth, with a smaller tooth between 
each. Scapes just reach the occipital border; second segment of funiculus barely 
one-fourth longer than first, Thorax fully twice as long as broad. Pronotum twice 
as broad as long, sides and front strongly convex, dorsum flattened. Mesonotum 
very slightly broader than long, almost circular. Epinotum one-third longer than 
broad; in profile pronotum and mesonotum united in an even convexity with a 
feeble impression at suture, meso-epinotal suture deep but not wide. Epinotum 
convex from base to foot of declivity. Node as long as broad, circular, convex on 
top ; in profile longer than high, anterior face short, rounded into dorsum, posterior 
face and dorsum united convex, ventral spine very short, sharp. Postpetiole one- 
fourth broader than long, convex from base to apex. First segment of gaster very 
slightly broader than long. Legs stout. 
Female. Length 14:5 mm. 
Differs from the worker in being larger, more robust and winged. Mayrian 
furrows feebly impressed on mesonotum. The mandibles slightly shorter and 
broader, the scapes do not reach the occipital border. 
Habitat—New South Wales: Gunnedah; Narrabri; Dubbo (W. W. Froggatt). 
The worker is re-described from a co-type received many years 
ago from the late W. W. Froggatt.

Plate XIV, figs. 4041 
Worker. Length 11-11-5 mm. 
Black; half of pronotum, whole of epinotum and node red. Mandibles yellow 
on basal half, apical half darker, antennae and tibiae brown, tarsi more reddish. 
Basal half of mandibles very finely and densely reticulate, with some large, 
shallow punctures, apical half longitudinally striate. Head finely striate longi- 
tudinally, the striae widely separated, interstices densely reticulate. Pronotum and 
mesonotum longitudinally striate-rugose. Epinotum and node more coarsely and 
irregularly rugose, all interstices densely reticulate. Postpetiole more finely rugose,
