98 A REVISION OF THE GENUS PROMYRMECIA EMERY (FORMICIDAE) 
one-third of the length of node; in profile a little higher than long, rounded above, 
anterior and posterior faces vertical. Postpetiole one and one-half times broader 
than long, broadest at middle. First segment of gaster broader than long, and 
broader behind than in front. Legs moderately long. 
Female. Length 16-18 mm. 
Colour identical with worker. Sculpture slightly coarser. Pilosity similar. 
Apart from the great size and bulk it closely resembles the worker. The scutellum 
is very small and inconspicuous. The metanotum is indicated by a sharp ridge. 
There are no traces of wings, but the anterior wing sclerites are indicated. 
Male. Length 13-14 mm. 
Black. Antennal scapes and first segment of funiculus, femora of all legs, and 
anterior tibiae and apical segments of tarsi, red; middle and posterior tibiae 
brownish. 
Mandibles shining, finely punctate. Head finely reticulate, coarser behind, with 
some large shallow punctures. Pronotum similar. Mesonotum similar in front. 
Epinotum with coarse reticulations forming faint transverse rugae. Node irregu- 
larly rugulose, with a strong longitudinal central carina. Postpetiole and gaster 
finely and densely punctate. 
Hair yellow, erect, long and abundant except on antennae and legs. Pubescence 
white, very fine, short and adpressed, particularly abundant on gaster. 
Head broader than long, broader in front than behind, sides strongly convex, 
occipital border short and straight. Mandibles short, not raised. Scapes fully 
twice as long as first segment of funiculus; second segment four times as long as 
first. Pronotum short, strongly convex. Mesonotum convex in front, flattened 
behind, mayrian furrows distinct but not strongly impressed; parapsidal furrows 
sharply defined. Scutellum strongly convex above, twice as broad as long. Epinotum 
twice as broad as long, strongly convex. Node slightly broader than long, sides 
strongly convex. First segment of gaster much broader behind than in front. 
Legs slender. Genitalia retracted. 
Habitat—Victoria: Altona (J. E. Dixon, % ; T. Greaves, % 2 ¢; J. Clark, 
% 2%); Bacchus Marsh and Coburg (C. Oke, % 2); Broadmeadows (F. P. 
Spry, %); Geelong (A. D. Butcher, 9 ); Patho (H. Potter). 
Winged females have not been seen in any of the nests examined. 
All the females found are similar to the worker and apart from 
their greater size are easily overlooked. Ergatoid females occur 
with several species of the genus, but winged forms also are known 
with the majority. 
This species has been confounded with aberrans Forel, from 
which it differs in the formation of the head and nodes. The colour 
and sculpture also are different. 
The various subspecies erected by Wheeler are based on this 
species, not on aberrans, which apparently he did not know. 
Promyrmecia eupoecila sp. nov.

Female. Length 14°5 mm. 
Mandibles and antennae yellow, head yellowish-red with a broad brown band 
across the forehead, extending from eye to eye and including the ocelli; pronotum
