E. Peringueyi Emery, at present unknown, prove to be similar to that 

 of Havilancli, it might be desirable in the future to re-erect Hagensia 

 as a sub-genus of Euponera, or even to make it a separate genus of 

 the Ponerini. (S.A.M., E.M., G.A. colls.)

The above variety alone has been found within our limits. It 

 differs from the type from Madagascar in having the metanotum 

 (epinotum) shorter, with a more rounded profile, and not in the 

 least angular. 



$ . 4"5 mm. Colour rather variable, castaneous brown or 

 piceous brown, with the posterior half of the head, the margins of 

 the pronotum, the sides of the epinotum and the apical margins 

 of the 1st and 2nd abdominal segments much paler ; 3rd-5th 

 segments ferruginous. Antennae, mandibles, legs, and clypeus fer- 

 ruginous yellow. Covered all over with a fine and dense yellowish 

 pubescence. The flavous pilosity is very short and scanty on the 

 head, thorax, and first two abdominal segments, longer and more 

 abundant on the clypeus and apical abdominal segments. Head and 

 thorax shining, the abdomen much more so. Head very shallowly 

 and finely punctured, the rest of the body impunctate or nearly so, 

 the mesopleurae very smooth and shining Head longer than wide, 

 almost parallel-sided, the posterior corners gently rounded. Clypeus 

 raised sub-angularly in the middle, the anterior margin bearing in 

 the centre a minute spine, plainly visible under a magnification of 

 30 diameters. Frontal carinae very narrow in the middle, diverging 

 posteriorly. 



Mandibles elongate and rather narrow ; the masticatory margin 

 with about 12 alternatingly large and small teeth, the apical tooth 

 very acuminate. The scape extends back nearly as far as the 

 occiput; 6th-8th joints of flagellum as broad as long. Eyes small 

 and flat, situated within the anterior fourth of the head. Pro- 

 mesonotal suture distinct. Pronotum twice as long as the meso- 

 notum, rounded in front, the sides somewhat flattened, Dorsum of 

 epinotum short, about the same length as the mesonotum, very 

 narrow at the base and widening towards the declivity. The latter 

 is very smooth and shining, with the sides tumid, and a little longer 

 than wide. Node of petiole, seen from above and in front, narrower 

 than in E. fossigera, and only very little wider above than below,
