$ . Has somewhat of the same characters as the genus Tapl- 

 noma, Forst., but the whole insect is broader in proportion to 

 its length, the head being nearly square, almost as broad in front 

 as posteriorly, the cheeks straight and not convex ; mandibles 

 narrower, when closed hidden under the anterior margin of the 

 clypeus, which is not incised as in Tapinoma ; antenna) 12-joiuted, 

 the apical joint as long as the preceding three joints ; eyes pro- 

 portionately much smaller. Thorax broad in front, compressed 

 posteriorly ; the pronotum proportionately broader in front than 

 in Tapinoma, and longer than the mesonotum ; the pro-noeso- and 

 meso-metanotal sutures distinct ; the metanotum with a still 

 shorter basal portion than in Tapinoma, and an obliquely truncate 

 apical portion ; legs shorter and stouter than in Tapinoma. 

 Pedicel and abdomen very like those in Tapinoma, but shorter and 

 broader, and the node of the pedicel distinctly raised and not 

 flattened on the pedicel. 



$ . Mandibles triangular, with 6 teeth ; clypeus wide, bisinuatc 

 along the anterior margin ; frontal area triangular, depressed, 

 longer than broad, antennal and clypeal hollows confluent ; 

 antennal carinae short, wide apart ; antenna) 12-jointed, somewhat 

 massive. Thorax and abdomen much as in Tapinoma, but propor- 

 tionately more massive ; the pedicel with an erect node ; wings 

 with one cubital and one discoidal cell. 



rf . Mandibles narrower than in the $ , acute ; clypeus trape- 

 /oidal, convex ; eyes very large, ocelli prominent ; antennae as 

 usual in tf , with L'i joints, the joints much longer proportionately 

 than in the $ . Thorax and abdomen as in the $ , but narrower- 

 Pedicel with the node thick, rounded above.
