broader behind than in front, with feebly convex posterior and lateral 
borders. Clypeus carinate its entire length, with the anterior border 
angularly projecting. Mandibles 8-toothed. Frontal area triangular, 
as long as broad. Frontal carinae strongly diverging. Antennae slen- 
der, basal funicular joints longer and more slender than the apical joints. 
Maxillary palpi rather short. Pro- and mesonotum not very convex, 
mesoépinotal constriction rather shallow, base of epinotum convex, 
declivity flat, very sloping, and forming a rounded obtuse angle with 
the base. Petiole narrow, thick, with more convex anterior, and less 
convex posterior surface and blunt border, which when seen from be- 
hind is broadly rounded and not produced upward in the middle. 
Gaster of the usual shape; legs rather slender. 
Opaque; mandibles, clypeus, and front of head slightly shining; 
frontal area subopaque. Mandibles very finely and densely striated. 
Erect hairs very sparse, short, blunt, clavate, present on the front, 
clypeus, ocellar region, gula, upper surface of the pro- meso- and epi- 
notum, and gaster. Antennal scapes and legs without oblique or sub- 
erect hairs. Pubescence grayish, sparse and fine on the head, thorax 
and appendages, denser on the gaster and concealing the surface so 
that this region appears gray. 
Head, thorax, and petiole bright red or orange red; gaster dark 
brown with the base of the first segment and the anal region red or 
yellow. Insmall specimens the posterodorsal portions of the head and 
the dorsal portions of the thorax and petiole are more or less infuscated. 
Even in the largest workers the ocellar triangle is fuscous. 
FEMALE. Length 4-5.5 mm. 
Head very much like that of the worker. Whole surface of body 
smoother and a little more shining. Hairs much longer and more 
abundant, present also on the posterolateral corners of the head. 
Pubescence yellow, very fine but distinctly visible on the upper surface 
of the head and thorax, and thick enough on the gaster to obscure the 
shining surface. 
Reddish yellow throughout, only the eyes, mandibular teeth and 
wing insertions black. Wings grayish hyaline, more infuscated towards 
their bases. Veins and stigma pale brown. 
Mate. Length 5.5-6 mm. 
(After Emery). Mandibles strongly dentate. Head short, broadest 
through the eyes which are large, behind the eyes broadly convex. 
Black; antennal funiculi usually brown, mandibles, legs, and genitalia 
paler yellow, femora often daker, coxae brown. Wings pale grayish, 
with dark veins. 
Host (Temporary). Probably F. schaufussi or one of its varieties.
