 "Worker. Ferruginous, shining; mandibular teeth, anterior 

 border of head, femora, tibise and the two posterior thirds of the 

 gaster, sometimes also the upper surface of the head with the 

 scapes, more or less brown. Mandibles nearly smooth and shining, 

 with a few, very scattered punctures; their terminal border armed 

 with three teeth anteriorly and indistinctly denticulate behind. 

 Head (without the mandibles) nearly as long as broad, slightly 

 narrowed in front, strongly rounded at the posterior angles. 

 Cheeks in front of the eyes, together with the spaces between the 

 eyes and the frontal carinse, longitudinally rugose, the rugae be- 

 coming semicircular around the articulations of the antennae; the 

 remainder of the head, with the clypeus and frontal area, smooth 

 and very shining. Antennae 12-jointed; funicular joints 2-7 

 transverse. Thorax with coarse rugae, transverse above, longitudi- 

 nal on the sides; the sculpture rather effaced on the disc of the 

 pronotum and the declivity of the epinotum. Pronotum convex, 

 unarmed above, its inferior border much raised above the articu- 

 lation of the anterior coxae and terminating in front in a blunt 

 denticle. There is a deep constriction between the mesonotum 

 and epinotum; the latter, very narrow above, terminates at the 

 juncture of the basal and declivous surfaces in two strong, acute 

 teeth, which are very divergent and directed upward. Petiole 

 surmounted by an acute cone, inclined forward; postpetiole trans- 

 verse, armed with a small dentiform tubercle at its anterior angles; 

 the petiole is transversely rugose above, the postpetiole nearly 

 smooth, except behind, where there are a few more or less effaced
