Psyche 
[March 
notum from above trapezoidal, broader than long, broader 
anteriorly than posteriorly, in profile feebly convex above. 
Mesonotum much narrower than the pronotum, slightly 
longer than broad, as broad in front as behind, with sub- 
parallel, slightly concave sides, in profile rounded and slop- 
ing backward to the pronounced mesoepinotal constriction. 
Epinotum broader than long, subrectangular from above, 
slightly broader behind through the prominent spiracles 
than in front; in profile with very convex, rounded base 
passing without an angle into the shorter, concave declivity. 
Petiole .small, nearly twice as long as broad, from above 
regularly elliptical, except at the posterior border where it 
is excised for the articulation of the gaster. A very feeble 
trace of the absent node is represented by the narrowly 
rounded anterior end of the flat dorsal surface ; the ventral 
surface is distinctly convex. Gaster broad anteriorly, rap- 
idly tapering and pointed posteriorly, the anterior trun- 
cated surface of the first segment longitudinally impressed 
in the middle for the accommodation of the petiole. Legs 
rather stout. 
Smooth and shining, especially the dorsal surface of the 
head, the pronotum and the gaster, meso- and epinotum 
more subopaque, very finely and densely punctate or reticu- 
late. Mandibles smooth, with a few scattered piligerous 
punctures. 
Erect hairs brownish, pointed, few in number, of unequal 
length, arranged as pairs of macrochsetse on the head, pro- 
and mesonotum as in some species of Paratrechina (subgen. 
Nylanderia). Gaster both dorsally and ventrally with simi- 
lar but shorter hairs, and the head and gaster also with 
more numerous short, suberect hairs or coarse pubescence. 
Antennal scapes and legs with pale, long, oblique, rather 
abundant pubescence. 
Head and thorax yellowish red, the former a little darker, 
with a fuscous cloud on the vertex. Manibles, petiole, legs, 
scapes and first funicular joint clear yellow; remaining 
funicular joints dark brown; mandibular teeth and gaster 
black; terminal tarsal joints reddish. 
Described from a single specimen taken by Mr. A. M. 
Lea in the Cairns District, Queensland, Australia, “among 
fallen leaves.”
