Text Figures 60 and 61

Worker maxima.-Differing from the maxima of the typical pompeius  HNS  in having the head distinctly smoother, more shining, and more superficially shagreened, the apical tooth of the mandibles much longer, the corners of the clypeal lobe much more acute, the superior border of the petiole somewhat more obtuse, the petiole and thorax brownish red, except the pronotum and dorsum of the mesonotum, which are dark brown. The thorax and coxae are covered with much longer, denser, and more conspicuous yellowish pubescence than in typical pompeius  HNS  .

Worker minima.-Very similar to the typical form but the thorax and legs paler, and the head and thorax with longer pubescence.

Described from a single maxima and seven minimae from Yakuluku (Lang and Chapin). There is also a single mermithergate from Medje which I have figured (Fig. 61). It is 15 mm. long, the gaster measures 8 mm. and is enormously distended with nematode worms of the genus Mermis, which are visible through the thinner portions of the lateral and ventral integument. The head and thorax are like the corresponding parts of the minima or small media and there are no traces of ocelli. The petiole, however, has a somewhat more pointed node and therefore approaches slightly the condition in the female.

Four males from Medje and Faradje and three females from Stanleyville are probably referable to this or to one of the other forms of pompeius  HNS  . They have the epinotum and legs more reddish than in the typical form. The wings of both females and males are slightly yellowish, with resin-colored veins and dark brown pterostigma.
