A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 143 
from the typical form, the colour and sculpture being identical. It can be regarded 
only as a slightly colour variety and the name retained to prevent future confusion. 
The female and male also are included in the above remarks as both are distinguished 
only by the red femora. 
Habitat —Victoria: Frankston (C. L. Barrett); Belgrave; Ferntree Gully 
(J. E. Dixon, J. Clark) ; Eltham (J. E. Dixon).

Worker. Length 12 mm. 
Black ; mandibles yellow, antennae and legs brown, tarsi reddish. 
Apical half of mandibles obliquely striate, basal half smooth and shining. Head 
finely striate-rugose longitudinally in front, irregularly rugose behind, interstices 
y punctate-reticulate. Pronotum and mesonotum longitudinally striate-rugose, 
more coarsely than on head, epinotum and node irregularly punctate-rugose, the 
declivity transversely rugose, interstices and bottom of punctures densely punctate- 
reticulate. Postpetiole and gaster densely and finely punctate, 
Hair yellowish, short and erect, long and abundant on mandibles, clypeus and 
gaster, none on antennae, very short and suberect on legs. Pubescence yellowish, 
Sparse except on gaster, where it forms a dense covering, some scattered pubescence 
on middle of posterior fourth of postpetiole. 
Head slightly broader than long, sides feebly convex, occipital border straight 
or feebly concave, angles rounded. Mandibles longer than head, parallel, external 
border straight, inner border furnished with five large, sharp, erect teeth on apical 
third, on the basal two-thirds the teeth short, sharp and directed backwards. Scapes 
not extending to occipital border by their thickness; second segment of funiculus 
one-fifth longer than first. Thorax fully twice as long as broad. Pronotum one 
and one-half times broader than long, strongly convex; mesonotum one-third 
broader than long, oval, meso-epinotal excision deep. Epinotum one-fourth longer 
than broad, feebly convex on top; in profile, dorsum of the three segments forming 
a straight line, meso-epinotal excision deep and wide, pro-mesonotal suture feebly 
indicated, pronotum strongly convex in front, forming a straight surface with 
mesonotum behind, mesonotum dropping convex at excision; epinotum raised 
slightly convex in front, dorsum flattened, rounded into declivity. Node a fraction 
broader than long, almost circular ; in profile as high as long, anterior face vertical, 
feebly convex rounded into dorsum, posterior face very short, broadly rounded 
into dorsum, ventral spine short and sharp, half as long as broad at base. Post- 
petiole barely one-third broader than long, almost semi-circular in front. First 
segment of gaster one-sixth broader than long, broader behind than in front. Legs 
Male and female unknown. 
Habitat —North Queensland: Herberton (E. Mjéberg). 
Described and figured from a co-type. Forel described this as 
a variety of gilberti, stating that the yellow jaws are the main 
reason for separating them. The only features in common on both 
forms is the pubescence on postpetiole and gaster.
