146 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
Male. Length 10:5 mm. 
Colour as in the worker. Sculpture similar but finer. Hair longer and more 
abundant throughout. 
Head very slightly broader than long, sides and occipital border convex. Man- 
dibles short, triangular, inner border with a sharp cutting edge, without teeth. 
Scapes extend slightly beyond middle of eyes; second segment of funiculus two 
and one-half times longer than scapes and eight times longer than first segment. 
Thorax fully twice as long as broad. Pronotum short, strongly convex. Meso- 
notum slightly broader than long, parapsidal and mayrian furrows impressed. 
Scutellum one-fifth broader than long, strongly convex in all directions. Epinotum 
almost twice as broad as long, convex transversely; in profile pronotum almost 
vertical, convex above. Mesonotum evenly convex from apex to base, highest at 
base, mayrian furrows distinct. Scutellum high, its base level with pronotum and 
epinotum, dome-shaped. Epinotum short, convex from base to foot of declivity. 
Node one-fifth broader than long, broader behind than in front, broadest at middle; 
in profile higher than long, anterior face straight and vertical, dorsum convex, 
rounded into short posterior face, ventral spine long, slender and sharp. Post- 
petiole one-third broader than long, constriction wide and deep. First segment of 
gaster one-fifth broader than long, broader behind than in front. Legs slender. 
Wings hyaline, slightly yellowish.

The following two forms are not represented in our collection, 
but for convenience Wheeler’s descriptions are given below. 
Myrmecia (Promyrmecia) fulvipes Roger s.sp. barbata Wheeler, Colony- 
founding among Ants, p. 71, 1933, % @. 
Worker. Length 12-14°5 mm. 
Head broader than in the preceding forms, especially behind, and therefore more 
rectangular. Mandibles somewhat shorter, stouter and distinctly curved, the sub- 
apical teeth smaller. Petiole and postpetiole as in fulviculis, but the former more 
sharply truncated anteriorly. Surface of head, thorax and petiole somewhat more 
shining, with more regular rugosity. Pilosity more abundant, conspicuously long 
on the gula. Pubescence dense, present on the postpetiole and gaster as in the 
typical fulvipes, but fine and dull, greenish-golden as in M. piliventris. Black; 
antennae and mandibles red; legs reddish-yellow as in fulviculis; sting black. 
Female (dealated). Length 14-5 mm. 
Very similar to the worker. Mandibles broader and somewhat shorter, with 
subapical teeth larger and occupying fully one-half of the inner border. Thorax 
more robust, with larger mesonotum and scutellum and shorter epinotum. Petiole 
and postpetiole broader. Gular hairs shorter; pubescence on abdomen as in the 
worker and fully as dense on the postpetiole as on the gaster. 
Described from ten workers from Dorrigo, New South Wales (W. Heron), and 
a worker and female from Belgrade.
