The beautiful carton nest of this ant is shown in Plate X, from a fine photograph taken by Mr. Lang at Ambelokudi. "It was built along the trunk of a tree near the ground. The ants, especially when squeezed, gave off a stench like certain bugs. They came out of the nest in great numbers and let themselves drop to the ground."

The female C. depressa is very aberrant in the form of the head, which is large, flat, and rectangular, with peculiar mandibles. It has long been known and has been repeatedly renamed, but only recently has it been correlated with the cospecific worker.
