with distinct though small anterior dorso-lateral tubercles forming the end of slight lateral carinae. Mesonotum with an anterior low, massive lobe on each side, descending carinae on each side terminating in small acute teeth, and bituberculate carinae on declivous surface just above mesoepinotal impression, of which the posterior tubercle is the larger. Basal surface of epinotum margined with carinae terminating in acute and sub-vertical spines. Peduncle and node of petiole of about equal length; in profile node with almost right-angled corners and a minute tubercle on median dorsal surface. Petiole, about 1 1/2 times longer than postpetiole, the latter with rounded dorsal and ventral surfaces. Postpetiole from above sub-pyriform with deeply excised posterior margin, distinctly wider than long. First gastric segment with parallel anterior and posterior margins, about as wide as long.

Described from one female and four workers taken by myself July 24, 1936, by the Oronoque River near its outlet with the New River of the Courantyne basin, British Guiana. The ants had formed in the sandy soil a crater 80 mm. in diameter, terminating in a turret 18 mm. high and 35 mm. in diameter in the form of a funnel opening. This led by a tunnel 8 mm. in diameter to the nest chamber 110 mm.
