ANTS FROM THE OTWAY RANGFjS. 
reaching the posterior third of head, almost uniformly thickened to apex; 
first segment of funiculus almost as long as the three following together, the 
others subequal to apical which is as long as the four preceding together. 
Eyes minute, composed of about seven facets, placed at posterior third of head. 
Anterior ocellus very minute, situated in a deep fovea, posterior ocelli repre- 
sented by minute punctures. Thorax twice as long as broad. Pronotum as 
broad as long, strongly convex on sides and in front, feebly convex above. 
Mesonotum almost twice as broad as long. Epinotum longer than broad ; 
epinotal declivity flat, the superior border rounded into dorsum. In profile 
the top of thorax straight, the pro-mesonotal suture deeply impressed. Node 
as long as broad, sides and anterior border strongly convex, in profile longer 
than high, the anterior face and dorsum forming a right angle, the corner 
rounded. A long broad translucent projection in front below, as high as long, 
with a small circular perforation slightly in front of the middle. Postpetiole 
broader than long, broader behind than in front, separated from the petiole 
and gaster by wide constrictions. Gaster slender. Legs long and slender. 
Female. — Length, 5 mm. (Dealated). 
Similar to worker but larger and more robust. The head is as broad 
behind as in front. Eyes and ocelli large. 
Habitat . — Beech Forest. Two nests under rotten logs. 
Much larger, and not close to any of the previously known 
forms. Many females were found in each nest, all were dealated. 
They are much more active than the members of Amblyopone , 
although like them they curl up and remain motionless for a 
few moments when disturbed. 
Genus DISCOTHYREA Roger 1863. 
Discothyrea turtoni, sp. nov. 
(PI. IV, figs. 5-6.) 
Worker. — Length, 2.3 mm. 
Russet ; apical segment of antennae and legs lighter. 
Pubescence very fine, short and abundant giving a somewhat silky sheen. 
Head longer than broad, broadest just behind the eyes, sides and occipital 
border convex. Mandibles triangular, edentate. Front of head produced and 
overhanging mandibles, the frontal carinae and antennae situated on the 
projection. Frontal carinae short, erect, truncate in front and behind, 
appearing as a thin blade separating the antennae and by no means covering 
their insertions. Scapes extending slightly beyond the eyes, thickened towards 
apex ; apical segment of funiculus as long as the other seven together, and 
one and three-quarters times longer than broad. Eyes small, circular, situated 
at the middle of the sides of head. Thorax one and one-half times longer than 
broad, pronotum twice as broad as epinotum and three times as broad as 
long, convex in front, anterior angles bluntly rounded. Pro-mesonotal suture
