The calcar of the female's hind tibia lacks the coarse teeth of Halictus, and the strigil of the anterior tibia exhibits no distinctive character, being almost identical in form with that of Halictus. There are five species bearing a tubercle on the second sternite, and it is difficult to separate them by the descriptions, and, even when the specimens are before the student, the task is not easy, for the group demands critical study for accurate determination. The task was com- plicated by the presence of two species in the one great aggregation of "nests," P. fulviventris (Friese) and P. arciferus Ckll. The following synopsis will help students, and the specific descriptions of two allotypes are appended. All the males have, of course, a yellow clypeal mark. It is possible that P. leptospermi is the female of P. Ice* w n c.
