Head broad, eyes black, orbits somewhat converging above, ocelli very large, a linear groove descending from middle ocellus, vertex obscurely tessellate; clypeus broad, yellow, its upper margin suffused with orange, and its anterior margin narrowly rufous; surface of clypeus rough so as to look like the skin of a lemon; labrum yellow, with appressed, very short, pale fulvous pubescence; mandibles long, simple, with a large yellow patch near the base, suffused outwardly into a reddish tongue, which gradually loses itself in the black of the tips. Antennæ hardly reaching beyond tegulæ, piceous, with the scape, funicle, and first and last joints of flagellum, rufescent. First joint of flagellum longer than the two following, but not so long as the three following. Sculpture of thorax cannot be seen for the pubescence.
