In the closely related E acuta Emery the third joint is described as being as long as broad, the remaining apical joints, except the terminal are transverse and the mandibular blades have only five teeth.

In the specimens before me the first gastric segment is heavily strigose longitudinally and the second segment is much more delicately sculptured, as described in the three forms mentioned above.

Differing from the t^TDical form in its somewhat smaller size and in having the striae of the second gastric segment not appreciably finer than that of the first, though with fewer punctures Fig. 7.— Ectomomyrmex exarata aequalis Mann, and petiole. Worker. Lateral view of thorax Described from several workers taken at Auki, Malaita and one at Tulagi, Florida. The Auki specimens were together and evidently belonged to the same colony, but I was unable to locate the nest. Typc.—M. C. Z. 9,155.
