130 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
Head, pronotum, mesonotum and anterior fourth of epinotum finely striate- 
rugose longitudinally, rest of epinotum transversely rugose. Node irregularly 
rugose. Postpetiole and gaster and all spaces between the rugae on head and 
thorax very finely and densely reticulate. 
Hair yellowish, long, erect and abundant throughout, shorter on legs, a few 
short bristle-like hairs at apex of scapes. Pubescence white, very fine and adpressed, 
longer and more abundant on postpetiole and gaster, forming a distinct covering 
but not hiding the sculpture, on the centre of gaster the pubescence is yellow. 
Head as long as broad, sides feebly convex, occipital border concave in middle, 
angles broadly rounded. Mandibles as long as head, external border concave, 
inner border furnished with twelve teeth, the third, fifth, eighth, tenth and eleventh 
large, sharp and directed very slightly backward. Frontal carinae one-fourth longer 
than broad in front. Scapes just reach occipital border; first and third segments 
of funiculus equal in length, the second almost one-third longer, apical not as long 
as the two preceding combined. Thorax twice as long as broad. Pronotum twice 
as broad as long, strongly convex in all directions. Mesonotum one-fourth broader 
than long. Epinotum broadly convex in front, flatly convex laterally; in profile 
pronotum strongly and evenly convex from apex to base. Mesonotum higher than 
pronotum, abruptly convex in front and behind, flat in the middle, meso-epinotal 
suture deep and wide. Epinotum, strongly convex from base to foot of declivity. 
Node slightly broader than long, convex in all directions; in profile as high as long, 
anterior face short and vertical, posterior face short and convex, continuous with 
dorsum, ventral spine short and sharp. Postpetiole one-third broader than long, 
sides strongly convex, constriction deep and wide. First segment of gaster one- 
fifth broader than long, strongly convex. Legs long and slender. 
Female, Length 14 mm. 
Colour, sculpture and pilosity as in the worker. Wings hyaline, nervures brown. 
Head slightly broader than long. Mandibles broader and the outer border 
straight; the teeth larger and broader. Scapes not reaching the occipital border 
by fully their thickness. Thorax barely twice as long as broad. Pronotum three 
times broader than long, convex in all directions. Mesonotum almost one-third 
broader than long, broadly convex in front and above, parapsidal furrows sharply 
impressed, mayrian furrow feebly indicated. Scutellum one-third broader than 
long, with a transverse impression in the middle. Epinotum almost twice as broad 
as long. Node about one-fourth broader than long, strongly convex in all direc- 
tions. Postpetiole twice as broad as long, strongly convex in front, constriction 
deep and wide. First segment of gaster fully one-fourth broader than long. Legs 
long and robust.
