alarm. The males and females are in flight during January

Myrmecia (. Promyrmecia ) fucosa, sp. nov. 
(PI. I, figs. 5, 6.) 
Worker. — Length, 10-11.5 mm. 
Red. Posterior half of head and two apical segments of gaster black. 
Mandibles and front of face to about the middle of eyes yellow ; antennae and 
anterior legs testaceous ; middle and posterior legs brownish. 
Head longitudinally and irregularly rugose, densely and finely reticulate 
between the rugae. Mandibles smooth and shining, with some scattered shallow 
punctures. Pronotum transversely arched-rugose. Mesonotum finely trans- 
verse striate. Epinotum transversely striate-rugose, coarser than on meso- 
notum but not so coarse as on pronotum. Node strongly and irregularly 
rugose. Postpetiole and gaster very finely and densely punctate. 
Hair greyish, long and erect, abundant on whole body, except the scapes, 
shorter and suberect on funiculus and legs. Pubescence greyish, long and 
abundant on postpetiole and gaster, forming a distinct covering, sometimes 
hiding the sculpture ; sparse elsewhere. 
Head slightly longer than broad, broader in front than behind, occipital 
border feebly concave, angles rounded. Mandibles not as long as head ; 
external border almost straight to apical third ; inner border nearly straight 
to basal third, then greatly reduced to the base ; furnished with nine teeth, 
the third, fifth, seventh, eighth and ninth twice as large as the first two ; the 
eighth forms the angle between the two apparent borders, the ninth placed just 
in front of middle of basal border. Frontal carinae extending to the posterior 
margin of eyes. Clypeus obtusely excised at middle in front ; anterior corners 
produced as blunt tooth-like angles. Labrum broadly rounded, extending 
outward to apex of clypeus. Eyes and ocelli large and prominent. Scapes 
not extending to the occipital border ; first segment of funiculus slightly shorter 
than second, but longer than third, apical one and one-half times longer than 
tenth. Thorax two and one-half times as long as broad. Pronotum broader 
than long. Epinotum about one and one-half times as long as broad, boundary 
between the dorsum and declivity feebly indicated. Node as long as broad, 
slightly broader behind than in front ; in profile slightly longer than high, 
nearly flat above, anterior face vertical, posterior face descending in a gradual 
slope ; the stalk in front is not quite half the length of node ; postpetiole 
very slightly broader than long, much broader behind than in front. First 
segment of gaster as broad as long, slightly broader behind than in front. 
Legs moderately long and slender. 
Female. — Length, 11-13 mm. 
Resembles the worker, but much larger and winged. The sculpture 
slightly coarser on head, thorax and node. The colour is similar, except that 
on two females examined the scutellum and sides of the mesonotum are brown, 
or blackish. 
Male. — Unknown. 
Habitat. — Victoria: Lake Hattah, Ouyen § (J. E. Dixon), Sea Lake § 
(J. C. Goudie), Wyperfield § ? (J. Clark). South Australia: Murray Bridge
