flagellum which bear a scanty microscopic pubescence. Pilosity 

 also absent, except on the last two segments of the abdomen, the 

 clypeus, mandibles and margins of the apical abdominal segments, 

 which bear a few long golden hairs. The whole body very shining 

 and polished, finely, evenly and sparsely punctured. The depressed 

 areas behind the antennal sockets finely striate. 



The head is parallel-sided, and nearly one-fifth longer than it is 

 wide ; in mandibularis the head is as long as wide and the sides are 

 slightly convex. The scape of the antennae is only a little longer 

 than half the head ; the flagellum is as long as the head, all the 

 joints except the apical wider than long, the apical joint as long as 

 the three preceding together. The eyes are exceedingly small, less 

 than - l mm., slightly sunk below the surface, and composed of 

 about 24 ill-defined facets. They are separated from the anterior 

 margin of the head by a distance less than their own length. 

 Mandibles as in mandibularis. Pro-mesonotal suture distinct, meso- 

 epinotal entirely obsolete. Pronotum without a median longitudina 

 impression. The lateral margins of the declivity of the epinotum 

 are raised into much stronger ridges than in mandibularis ; the 

 ridges are abruptly truncate above. Seen in profile, the thorax is 

 much flatter dorsally than in mandibularis. The node of the petiole 

 is not much narrower in front than behind, and the angular projec- 

 tion of the ventral lamella is truncate at the apex, otherwise like 

 mandibularis. The 2nd abdominal segment is less globose, and the 

 legs are stouter and shorter proportionately than in that species. 

 The 1st and 2nd abdominal segments are distinctly longer than wide. 



2 . 10 mm. Similar to the $ but winged, and with well- 

 developed eyes, 03 mm. long, and three small ocelli. The colour 

 of the head and thorax is darker than in the £ . The mesonotum 

 is a little wider than long, and two and a half times as long as the 

 pronotum. The parapsidal sutures are deep and well defined only 

 on the posterior half of the mesonotum. All the transverse thoracic 

 sutures distinctly defined. The scutellum is half as long as the 

 mesonotum. Dorsum of epinotum as long as the scutellum, with a 

 feeble median impression at the extreme base. The projection of 

 the ventral lamella of the petiole blunt, but not truncate at the apex 

 as in the £ . Other characters as in the $ . 



The single specimen of this sex was found alive and dealated 

 under a stone. Of the $ £ I have two specimens, one considerably 

 damaged. The latter was taken dead on the rubbish-heap belonging 

 to a nest of Tetramorhtm Blochmanni, Forel, r. continentis, Forel, 

 and the other in a similar situation, and also dead, from the nest of
