ends more nearly parallel. Maxillary palpi rather long, 6-jointed. 
Antennal scapes distinctly incrassated at their tips; jomts 2-4 of 
the funiculi a little more slender, but scarcely longer than the penulti- 
mate joints. Pro- and mesonotum distinctly depressed or flattened . 
above; mesoépinotal impression shallow and broad at the bottom; 
epinotum with the base a little shorter than the declivity, the former 
slightly convex in profile and passing through a rounded angle into 
the sloping declivity. Petiole high and rather broad, much com- 
pressed anteroposteriorly, the anterior surface somewhat convex, 
the posterior flat, the upper border cultrate and sharp; seen from be- 
hind the sides are straight and diverge upward and the superior border 
is horizontal and entire. 
Surface of body very finely shagreened, head and gaster shining, 
thorax subopaque; mandibles finely striatopunctate; frontal area 
subopaque; surface of gaster finely and sparsely punctate and trans- 
versely shagreened, with the sheen of the gaster of exsectoides, 
obscuriventris, and nepticula, but slightly less shining. 
Hairs golden yellow, sparse and coarse, present on the clypeus, front, 
vertex, pro- and mesonotum, fore coxae, and gaster; slightly shorter 
on the gaster than in exsectoides, long on the venter. Pubescence 
very fine and sparse, most clearly visible on the gaster and legs. 
Light or dark ferruginous red, legs a little darker, and more brownish; 
gaster, posterior half of head, a large spot on the pronotum, and a small 
one on the mesonotum, black. 
FemMaLeE. Length 7.5-9 mm. 
Smaller than the female of exsectoides. Resembling the worker 
in color, but the tips of the scapes, the pleurae, bases of fore coxae 
and three large spots on the thorax are dark brown, and the surface 
of the body, especially of the head and thorax, is more glabrous and 
shining. The clypeus is ecarinate, with the anterior border depressed, 
the mandibles rather superficially striatopunctate. 
The pilosity of the head is like that of the worker, but the hairs 
on the remainder of the body are very different. The pronotum, 
mesonotum, scutellum, upper pleurae, and gaster are covered with 
sparse, very long and coarse, appressed, tawny hairs. The border 
of the petiole also bears a number of these peculiar hairs. Wings 
uniformly tinged with brown, with pale brown veins and stigma. 
Mae. Length 7-8 mm. 
Head like that of the male easectoides, with straight posterior border, 
but with somewhat more broadly elliptical eyes. Mandibles edentate, 
narrow, and pointed. Thorax and gaster, robust, the latter flattened 
and rather broad. Petiole thick and low, with blunt, entire, trans- 
verse border. 
Whole body more shining and more finely shagreened than in ea- 
sectoides.
