Pheidole speculifera. Emery

Four soldiers from Faradje, without further data, and five workers from the stomach of a frog (Rana ornalissima) from Garamba agree veiy closely with Emery's description of the types from Abyssinia, but the workers are darker. Forel has described a variety, cubangensis, from Mossamedes and records it also from the Belgian Congo, but this form seems to be very close to the type. My specimens are not as large, since none of the soldiers measures more than 6 mm., whereas Forel gives the length of cubangensis as 7 mm. He describes the whole head as opaque, whereas my specimens have a pair of elliptical, very smooth, and shining areas on the vertex in the midst of the opaque and finely punctate sculpture (Fig. 36a and b).
