A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 95 
Described from a single specimen taken by W. W. Froggatt at Wagga, New 
South Wales. Another specimen, perhaps to be regarded as representing a distinct 
variety of sericata, from Meningie, South Australia (L. H. Minchin), measures 
only 12 mm. and has the mesonotum coarsely, transversely and arcuately rugose 
with large interspersed punctures and the petiolar node longer and more coarsely 
rugose.

Myrmecia (Promyrmecia) aberrans Forel s.sp. taylori Wheeler, Colony- 
founding among Ants, 1933, p. 53. 
Length 15 mm. 
Larger than froggatti but similarly coloured; body somewhat more opaque; the 
rugae strong on the head and thorax but less sharp than in the preceding forms, 
arcuate and transverse on the mesonotum, reticulate on the epinotum and petiole. 
Node of the latter more sharply cuboidal than in froggatti, postpetiole nearly twice 
as broad as long, like the gaster subopaque and finely punctate, with longer and 
denser, yellowish pubescence. Pilosity on the body longer and more abundant 
than in the preceding forms. 
Described from a single specimen taken by Frank H. Taylor in the Roma 
District, Queensland.

founding among Ants, p. 51, 1933, &. 
Worker. Length 11-13 mm. 
Black ; mandibles, antennae and tarsi reddish-yellow, teeth of mandibles blackish- 
brown, articulations of legs reddish-brown. 
Shining. Mandibles obliquely and coarsely striate. Head finely striate longi- 
tudinally. Pronotum and mesonotum longitudinally striate, coarser than on head. 
Epinotum more coarsely striate-rugose transversely, interstices densely reticulate. 
Node irregularly punctate-rugose, almost circularly rugose. Postpetiole and gaster 
densely and microscopically punctate. 
Hair yellowish, sparse, short and erect, longer on clypeus and apex of gaster. 
Pubescence greyish, sparse throughout. 
Head very slightly broader than long, as broad in front as behind, sides fully con- 
vex, occipital border deeply concave at middle, angles broadly rounded. Mandibles 
fully their width shorter than head; external border straight or feebly concave at 
middle, inner border straight to basal fourth then abruptly reduced to base, 
furnished with nine large broad teeth, first two smallest, ninth forms an angle 
between the two apparent borders. Scapes not extending to occipital border by 
fully twice their thickness; second segment of funiculus as long as first; third 
slightly shorter. Thorax twice as long as broad; pronotum twice as broad as long, 
sides and front convex, dorsum flattened ; mesonotum as long as pronotum, almost 
one-third broader than long, convex in all directions; excision deep and narrow; 
epinotum one-third longer than broad, convex transversely; in profile evenly 
convex from apex of pronotum to base of mesonotum, a very slight depression 
at pro-mesonotal suture, meso-epinotal excision deep and narrow; epinotum convex 
from base to foot of declivity. Node one-fifth broader than long, sides strongly 
convex, anterior and posterior borders feebly convex; in profile one-fifth higher 
than long, anterior and posterior faces straight, vertical, both bluntly rounded into 
the slightly convex dorsum, ventral spine broad, triangular, bluntly pointed. Post-
