With few exceptions all the Attii have the sur-face of the body opaque and of a ferruginous, brown or blackishcolor. All the species, moreover, though very powerful and able tomake surprisingly extensive excavations in the soil, are very slow andsedate in their movements. The sting of the workers is vestigial, but.
