Head and thorax feebly, gaster strongly shining. Mandibles shining, finely punctate and, at basal half with delicate striae. Front and vertex with strong, irregular, longitudinal striae, the surface between the striae rugulose; striae of side-, scrobes, and occiput irregular, subconcentric. Pro- and mesonotum rugulose, with irregular, interrupted, longitudinal striae. Epinotum finely and superficially rugulose and shining. Petiole and postpetiole irregularly and coarsely eostate, the eostae on the postpetiole reticulate and enclosing late pits. Gaster with fine and regular punctation. Long and fine erect hairs abundant on body, especially the gaster. Hairs on appendages shorter and semierect. Black, mandibles red, appendages yellowish brown. Viti Levu: Nadarivatu. Near strialella but larger and more coarsely sculptured, without well-defined antennal scrobes and with the inferior epinotal spines long and pointed, in strialella these are short and more rounded api- cally. Type — M. C. Z. 8,707. The colonies are small and live beneath stones or in the ground. The workers are very slow-moving. Key to Melanesian Species of Rogeria. 1. Epinotal spines weak, shorter than their distance apart at ba
