ANTS FROM THE OTWAY RANGES. 
Hair yellow, long and erect, very sparse on head, more numerous on gaster, 
not apparent on thorax, node, antennae and legs. Pubescence very fine and 
adpressed, sparse on body, abundant on antennae and legs. 
Head very slightly longer than broad, almost square, sides and occipital 
border feebly convex, angles broadly rounded. Mandibles triangular, furnished 
with six strong sharp teeth. Clypeus sharply carinate on anterior two-thirds, 
b rontal area transversely triangular. Frontal carinae longer than broad in 
front, almost parallel. Scapes extending beyond occipital border by half 
their length ; first segment of funiculus twice as long as broad and slightly 
longer than second, remaining segments longer than broad, apical twice as 
long as broad, sharply pointed. Eyes circular, rather flat, placed slightly 
behind middle of sides. Ocelli very small. Thorax twice as long as broad. 
Pronotum one-fourth broader than long, strongly convex, twice as broad as 
rest of thorax. Mesonotum one-fourth longer than broad, sides almost straight. 
Epinotum as long as broad, broader behind than in front ; in profile the pro- 
notum and mesonotum form a long convexity with a slight depression at the 
suture. Meso-epinotal suture deeply excised, epinotum convex, dorsum 
projecting slightly beyond the declivity face, hardly overhanging ; declivity 
face straight to near top where the projecting dorsum gives a concave appear- 
ance, almost one-third longer than dorsum. Node scale-like but twice as broad 
as long, very blunt above, convex transversely; in profile, the anterior face 
strongly convex, posterior feebly convex, twice as high as long. Gaster one- 
fourth longer than broad. Legs slender. 
Habitat . — Beech Forest, in rotten logs. 
Prolasius ftavicornis, sp. nov. 
(PI. IV, fig. 31-32.) 
Worker. — Length, 3-4 mm. 
Brownish-black ; antennae and coxae yellowish ; legs and node brown. 
Shining, microscopically punctate throughout. Mandibles very finely 
striate longitudinally. 
Hair yellow, long and erect, sparse throughout except on gaster. Pubescence 
very fine, short, sparse except on antennae and gaster. 
Head very slightly longer than broad, sides and occipital border strongly 
convex. Mandibles triangular, furnished with five strong, sharp teeth behind 
the apex, Clypeus produced and bluntly pointed in front, subcarinate on 
anterior two-thirds above. Frontal area broad, almost convex behind. Frontal 
carinae barely as long as wide in front. Eyes large, convex, placed behind the 
middle of sides. Ocelli very small. Scapes extending beyond occipital 
border by almost half their length ; first segment of funiculus as long as the 
three following together, second to fourth as broad as long, remainder longer 
than broad, pronotum one-third broader than long, strongly convex. Meso- 
notum half as wide as pronotum, one-fourth longer than broad, slightly broader 
in front than behind, sides almost straight. Epinotum one-fourth narrower 
than pronotum, twice as broad behind as in front. In profile the pronotum 
and mesonotum together feebly convex, a deep and wide excision between 
mesonotum and epinotum, the latter dome-shaped, the declivity abrupt and 
straight, almost one-third longer than dorsum. Node scale-like, two and a 
half times higher than long, anterior and posterior faces convex, top edges 
straight and rather sharp. Gaster ovate. Legs robust.
