Thorax with compressed, spatulate inferior pronotal spine and stout and acute lateral pronotal spine which is largest spine of body, distinctly larger than epinotal spine. Between these spines the pronotum is in some workers transversely carinate and bears 5-8 irregular, acute, and setigerous tubercles. Mesonotum surmounted by a disk bearing on its rim irregular tubercles, in this resembling

The entrance to the nest was in the form of a circle of twigs loosely adhering together. This led by three tunnels, first to the original small chamber 4.5 cm. in diameter x 2.5 cm. high and thence to a deeper and larger chamber 2 x 11 x 5 cm. high, the latter containing the fungus garden which was partly pendant, partly sessile.
