124 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
Mandibles striate-punctate on apical half and a row of shallow piligerous punc- 
tures along the centre from base to apex. Head very finely striate longitudinally, 
very finely and densely reticulate between the striae. Pronotum finely striate and 
reticulate as on head but striae more spaced, longitudinal in the middle, arched on 
the sides. Mesonotum much more finely striate, the striae longitudinal but diverging 
outward in front. Epinotum rather coarsely striate transversely. Node circularly 
striate-rugose. Postpetiole and gaster very finely and densely punctate. 
Hair yellow, short and erect on head, thorax and node, longer and more abundant 
on postpetiole and gaster, very short and sparse on antennae. longer and suberect 
on legs. Pubescence white, very fine and adpressed, longer and more abundant 
on gaster, where it forms a thin covering. 
Head one-fifth broader than long, sides convex, occipital border straight or 
feebly concave. Mandibles as long as head, external border feebly convex, inner 
border feebly convex, furnished with five large, sharp, erect teeth. Frontal carinae 
as long as broad behind. Scapes extend beyond occipital border by fully their 
thickness; second segment of funiculus one-fourth longer than first. Thorax twice 
as long as broad. Pronotum twice as broad as long, strongly convex in all direc- 
tions. Mesonotum one-eighth broader than long, circular, convex above. Epinotum 
fully one-fourth longer than broad, convex laterally; in profile pronotum and 
mesonotum united in an even curve with a feeble indention at the suture, top of 
mesonotum scarcely higher than top of pronotum and epinotum. Meso-epinotal 
suture deep and wide. Epinotum straight in front, broadly rounded into the 
declivity. Node one-fourth broader than long, convex in all directions: in profile 
slightly longer than high, anterior and posterior faces erect, short, broadly rounded 
into dorsum, ventral spine short and sharp. Postpetiole twice as broad as long, 
ee strongly convex. First segment of gaster one-eighth broader than long. Legs 
slender. 
Female. Length 18:5-19 mm. 
Colour as in the worker except that the first segment of gaster is entirely red 
at base, shading to brown at apex of segment. Wings hyaline with a yellowish tinge. 
Sculpture similar but coarser. 
Hair longer and more abundant. 
Head one-fourth broader than long, mandibles as long as head, broader and 
more conyex than in worker. Scapes just reach the posterior border. Node barely 
twice as broad as long, posterior and anterior faces straight, sides convex. Post- 
petiole twice as broad as long, strongly convex on front and sides. First segment 
of gaster one-fourth broader than long. Legs robust. 
Male. Length 14 mm. 
Head, pronotum, mesonotum and three last segments of gaster black. Mandibles 
brownish-red, antennae, legs, sides, mesonotum, epinotum, both nodes and first 
segment of gaster yellowish-red. 
Hair white, erect, long and abundant throughout. Pubescence white, very fine 
and adpressed, longer and more abundant on gaster. 
Head very slightly broader than long, convex behind eyes. Mandibles short 
and broad, furnished with three teeth. Scapes twice as long as broad and twice as 
long as first segment of funiculus, second segment three times longer than first. 
Thorax twice as long as broad. Pronotum four times broader than long, strongly 
convex. Mesonotum as long as broad, parapsidal furrows weakly impressed. 
Scutellum one-fourth broader than long, broadest in front. Epinotum twice, as 
broad as long, convex laterally; in profile pronotum erect, strongly convex in 
front. Mesonotum high and convex, highest in middle. Scutellum dome-shaped. 
Epinotum straight on top, as long as declivity into which it is rounded. Node
