57. Ponera aliena .

Worker. Length 1 1/2 line.-Scarcely differing from the Ponera contracta of Europe; the antennae are however rather shorter, and the apical joint longer; the legs are shorter and thicker; but the most distinctive difference is the thickness of the scale, or node of the petiole, which in the present species is much thicker, particularly at its upper margin; in other respects they scarcely differ: the eyes are wanting, as in P. contracta : the palpi have not been examined.

Hab. Brazil. (Coll.W. Swainson.)

This species doubtless resembles very closely the Ponera ruficornis of Spinola, but he describes his insect as black, with red antennae: our species is entirely of a brownish-yellow, and appears to he distinct.
