ANTS FROM THE OTWAY RANGES. 
Female . — Differs from the worker only in slightly larger size ; the spines 
of epinotum slightly shorter. Wings missing. 
Genotype, Pseudonotoncus hirsutus , n. sp. 
In size and sculpture this genus is apparently nearest to 
Notorious. The same variation in size of workers is found in 
both genera. In many respects it is even closer to Diodontolepis 
Wheeler, but the latter is much larger, with a different sculpture, 
All these genera have the maxillary palpi with six, and the 
labial palpi with four segments. 
Pseudonotoncus hirsutus, sp. nov. 
(PI. IV, fig. 23-24.) 
Worker. — Length, 3. 3-3. 8 mm. 
Chocolate brown ; antennae and legs somewhat lighter ; gaster black. 
Shining. Mandibles finely striate, clypeus striate-rugose. Head finely 
striate-reticulate, scapes very finely reticulate. Pronotum and mesonotum 
coarsely and irregularly rugose. Dorsum and declivity of epinotum trans- 
versely striate, the striae continued longitudinally on sides. Top of node 
rugose, anterior face smooth and shining, posterior face weakly striate trans- 
versely. Gaster smooth and shining. 
Hair yellow, long, slender and erect, abundant throughout, shorter and 
suberect on antennae and legs. Pubescence very fine, sparse, apparent only 
on gaster. 
Head very slightly broader than long, broader behind than in front, sides 
and occipital border feebly convex, angles broadly rounded. Mandibles 
furnished with six strong sharp teeth, the first, second and fourth largest. 
Clypeus convex in front, carinate above, the apex forming a sharp tooth-like 
projection in front. Frontal area large, transversely triangular. Frontal 
carinae as long as broad in front, one-third broader behind, sharply margined. 
Scapes extending beyond occipital border by almost one-fourth their length ; 
first segment of funiculus twice as long as two following together, second to 
ninth longer than broad, tenth as long as broad, apical pointed, as long as two 
preceding together. Eyes large, convex, placed near posterior third of sides. 
Ocelli small. Thorax one and two-thirds times longer than broad. Pronotum 
twice as broad as long, strongly convex. Mesonotum as long as broad, sides 
almost straight, very feebly convex ; a wide constriction separates epinotum. 
The latter broader than long, terminating in two long sharp spines, as long 
as their distance apart, almost parallel ; two shorter, but sharp, teeth on 
lateral borders of declivity, wider apart than those on dorsum. In profile 
pronotum and mesonotum form a strong convexity, interrupted at suture. 
Meso-epinotal suture deeply impressed. Epinotum slightly convex, the spines 
slender, one-third shorter than dorsum, directed upward and backward, 
declivity straight, twice as long as dorsum, with a strong sharp spine at basal 
third, thicker and shorter than dorsal spines. Node twice as broad as long, 
strongly convex in front, feebly convex behind, furnished above with two broad 
sharp-pointed spines, their outer edges convex ; in profile almost twice as high
