Male very black and shining; head dull, indistinctly punctured; mouth ferruginous: antennae tawny, dusky at their tips, the scape and second joint ferruginous, the latter stouter than the third; and elongate obconic. Thorax indistinctly und irregularly striated; scutel large and glossy; postscutel convex, delicately punctured, with the angles scarcely visible. Petiole elongated, basal joint clavate, second subglobose; abdomen small, ovate-conic, the tip ochreous. Wings with a pale fuscous-yellow stigma, the nervures almost invisible. Legs long and slender, ochreous-white; the coxae, thighs and tibiae pitchy, except at their extremities: length 1 1/3, expanse 3 lines.
Neuter smooth pale reddish ochre: head large, oblong, convex, finely striated, the margin and clypeus more or less fuscous; mandibles ochreous. Antennae stout, and ochreous, scape long, second joint stoutish, elongated, third and six following very short, transverse and increasing in diameter, the three last joints forming a stout fuscous club. Thorax much narrower than the head, indistinctly striate-punctate, oblong, narrowed at the middle; postscutel producing two distinct acute divaricating dark spines. Petiole stoutish, with a few hairs, basal joint elongate-clavate, subrugose, second globose: abdomen small, very polished, with a few short scattered hairs, ochreous, brown beyond the middle, the apex ochreous. Legs short, stout, and ochreous: length 1 to 1 1/4 line. The male of this species greatly resembles that of S. Westwoodii, but independently of its smaller size and somewhat different sculpture, the postscutel has only two minute points, which are scarcely visible; the tarsi, especially the hinder, are white in some lights, and the nervures of the wings are difficult to discern.
The only evidense I ave of the above insects being the males and neuters of one species is my having discovered them together. I beat two males and two neuters out of a Privet hedge, the 31st July 1852, on the Folkstone road near Dover. At first I considered the neuters to be small varieties of Myrmica unifasciata, but on obtaining typical specimens at Pau, the difference was manifest; the dark band on the body of that species covering more than half the basal segment, whilst the antennae are entirely fulvous. This strong resemblance however leads me to think that its male may be similar to the same sex of our species, and consequently that it may be a Stenamma, as previously intimated.
