Description
Text Figure 53
Worker.- Length 2.4 to 2.7 mm.
Head without the mandibles distinctly longer than broad, broader behind than in front, with feebly concave posterior border and feebly convex sides. Eyes flat, in front of the middle of the head, about one-fifth as long as its sides. Mandibles convex, with about a dozen even, crowded teeth. Clypeal notch about one-fourth the length of the anterior border, broader than deep, with sharp, slightly produced corners. Posterior clypeal border distinct; frontal area and groove obsolete; frontal carina; nearer to the sides of the head than to each other. Antennal scapes extending about one-sixth their length beyond the occipital border; funicular joints 2 to 10 perceptibly longer than broad. Thorax short, seen from above with distinctly angular humeri; premesonotal and mesoepinotal sutures distinct: pro- and mesonotum moderately convex, the latter broadly elliptical, slightly broader than long; mesoepinotal constriction rather deep, acute; epinotum as long as broad, broader behind than in front, in profile with a short base, rising rather steeply from the mesoepinotal suture, onefourth as long as the flat, backwardly sloping declivity. Petiole elliptical, flat, its node obsolete. Gaster rather voluminous, its first segment, overlying the petiole; anus terminal. Logs rather slender.
Shining: very finely and uniformly punctate.
Hairs sparse blackish, erect, rather coarse, present on the clypeus, vertex, pro-, meso-, and epinotum, and all the segments of the gaster. Pubescence grayish, short and fine, rather abundant, covering the whole body but not concealing the shining surface,
Castaneous brown; thorax and anterior portion of head paler; mandibles, insertions of antoniae, funiculi, tarsi, and articulations of legs yellowish brown.
Materials Examined
Described from numerous specimens taken by Mr. C. C. Gowdey at Kampala, Uganda. I at first supposed this form to be E. ilgi subspecies stygium Santschi, described from British East Africa, but careful perusal of the description shows that it is quite distinct.
