in front than behind, with convex and rounded posterior border 
and straight sides. Eyes moderately large, convex. Clypeus with 
broadly rounded and somewhat projecting, entire, anterior border, 
strongly carinate, the carina angular in profile. Frontal carinae paral- 
lel. Maxillary palpi very long, 6-jointed. Antennae very long and 
slender, the scapes straight at the base, funiculi not thickened towards 
their tips, the median joints more than 14 times as long as broad. 
Thorax, especially the pro- and mesonotum, long, these portions not 
very convex, evenly rounded; mesoépinotal constriction not deep; 
epinotum low and evenly rounded, without distinct base and decliv- 
ity. Petiole narrow, rather thick, its anterior and posterior surfaces 
convex, its margin blunt, rounded and entire when seen from behind 
or only slightly impressed in the middle. Gaster elongate elliptical; 
legs long. 
Whole body shining and very finely and superficially shagreened; 
mandibles finely striated and coarsely punctate. 
Hairs yellowish, sparse, confined to the gaster and the upper surface 
of the head; absent on the gula, thorax, and petiole; blunt and coarse 
on the gaster. Legs with only the graduated series of bristles on 
the flexor surfaces of the tibiae. Pubescence fine and rather dilute, 
visible on the gaster and legs. 
Pale yellow; mandibles reddish; gaster often with a brownish tint; 
sometimes the whole head is reddish. 
FremMaLe. Length 7-8 mm. 
Rather stout; head nearly as broad as long, subrectangular, a little 
narrower than the thorax. Border of clypeus more flattened than in 
the worker, petiole more compressed anteroposteriorly, with flat pos- 
terior surface. 
Sculpture and pilosity as in the worker, but the body, especially 
the head and mesonotum, more reddish. Wings colorless, with pale 
brown veins and stigma. 
Mate. (After Emery). 
Characterized by its pale color. The whole body is yellow, the 
head and the gaster behind somewhat darker. Vertex and tips of 
funiculi brown; only the eyes black. Head much smaller than in the 
other subspecies. The eyes too are somewhat smaller.

I have not seen the male of this the typical form of the species but 
the male of the var. succinea described below is probably very similar.
