RoGERiA (Irogera) striatella, sp. nov. Fig. 19. Worker. Length mm. Head subquadrate, distinctly longer than broad, sides nearly straight, posterior border straight. Mandibles with six acute triangular teeth, the three apical ones larger than the others. Clypeus with flat basal and apical halves separated by an obtuse angle, anterior border rounded. Frontal area strongly impressed but not sharply outlined. Frontal carinae nearly straight,. Fig. 19.— Rogeria (Irogera) striatella Mann. Worker. Lateral view of thorax and petiole. moderately divergent, as long as the antennal scapes and bordering broad, well-defined scrobes. Antennal scapes thick, extending four fifths the dis- tance to occipital corners; funicular joints 2-8 transverse, club slender, about as long as the remainder of funiculus, with the terminal joint longer than the other two together. Eyes large, feebly convex, situated at sides of head in front of middle. Pro- and mesothorax subglobose, suture barely discernible, humeri narrowly rounded. Mesoepinotal impression strong. Epinotum flat at base, then strongly concave and margined at sides, separated from declivity by a margined angle; declivity concave; spines about as long as their distance apart at base, strongly divergent, inferior spines short, triangular. Peduncle a little shorter than petiolar node, with a short, stout anteroventral tooth; node broader than long; in profile as long as high, highest in front. Shining. Mandibles sparsely, very delicately striate and punctate. Front and vertex with fine, interrupted longitudinal striae, rugulose between; the striae on occiput reticulate and interspersed with large punctures; scrobe rugulose in front, nearly smooth behind.
