A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 127 
| brown, apex and teeth more reddish, apical half of scapes, funiculus and legs 
_ yellowish-red. Node and postpetiole red. 
Head finely striate longitudinally in front, more striate-rugose behind, very 
finely and densely punctate between the striae. Pronotum and mesonotum finely 
_ ‘Striate-rugose longitudinally. Epinotum transversely rugose. Node irregularly 
| rugose; the spaces between the rugae on thorax and node finely and densely 
punctate. Postpetiole and gaster very finely and densely punctate. 
7 Hair yellow, long and erect, abundant on mandibles, clypeus, thorax, nodes and 
| gaster, sparse on head, none on antennae. Very short and suberect on legs. Pubes- 
cence very fine and adpressed, white, abundant throughout, forming a distinct 
_—s covering on gaster but not hiding the sculpture. 
Head as long as broad, sides feebly convex, occipital border straight or feebly 
concave, angles rounded. Mandibles one-eleventh longer than head, convex on 
basal third, straight on central third and from there to apex strongly convex, 
inner border furnished with fourteen teeth, the third, sixth, ninth, tenth, eleventh 
and twelfth long, sharp and curved backward, the others smaller and straight, 
the twelfth forms a distinct angle. Frontal carinae one-fourth longer than broad 
behind. Scapes extend beyond occipital border by their thickness; second segment 
of funiculus one-sixth longer than first, remainder subequal. Thorax fully twice 
as long as broad. Pronotum one-third broader than long, convex in all directions. 
Mesonotum one-fourth broader than long, convex. Epinotum about one-fifth longer 
than broad; in profile pronotum strongly convex, rising abruptly. Mesonotum 
convex, higher than pronotum, constriction between mesonotum and epinotum 
wig d and wide. Epinotum convex from base to foot of declivity. Node as long 
as broad, very slightly broader behind than in front; in profile as high as long, 
anterior face short and vertical, rounded into dorsum, posterior face and dorsum 
united in a convexity. Ventral spine short and sharp. Postpetiole one-third 
broader than long, sides strongly convex, the constriction deep and wide. First 
segment of gaster broader than long, broader behind than in front, sides strongly 
convex. Legs long and slender. 
Female. Length 15-16 mm. 
Larger and more robust than the worker. Colour similar, sculpture coarser, 
pilosity longer and more abundant. Mandibles shorter and broader, teeth erect 
on apical half, inclined backwards on basal half. Scapes not extending to occipital 
border by almost their thickness. Node larger. Postpetiole hemispherical, one- 
third broader than long. Legs robust. 
Male unknown. 
Habitat—Queensland: Peak Downs (type locality) ; Rockhampton; Bowen 
(Dr. J. Mackay) ; Townsville (J. P. Dodd) ; Gayndah (F. A. Cudmore). 
The colour of this species varies considerably. On some examples 
‘the whole thorax is black, whilst on others it is red; most examples 
have the thorax more or less marked with red. 
Re-deseribed from a series of three specimens in National 
‘Museum collection. They were received from the Museum Godef- 
in 1888. 
Promyrmecia wilson sp. nov. 
Plate XV, fig. 66 
a ; 12°5-14 mm. 
Mod cod rong black. Mandibles, labrum and apex of clypeus yellow. Antennae, 
x, nodes and legs yellowish-red.
