Anglochora pura Say. Taken at 10:30 a. m., August 6. Obtained pollen from the large stamen by alighting on it, crawling to the tips, and collecting it from the terminal pores.

No humblebees were taken around Lawrence, although many were noticed working on the plants; consequently the names of the species noticed cannot be given. In St. Joseph, Mo., there were taken at three p. m., when bees were not generally seen working on the plant:
Bombus virginicus. One specimen.
Bombus pennsylvanicus. One specimen.
An examination of fifty flowers taken at this time showed from the dented condition of the small stamens that they had all been visited.
Between eight and nine a. m., September 3, when bees were numerous, there were taken:
Bombus virginicus. Two specimens.
Bombus pennsylvanicus. Twelve specimens.
Bombus scutellaris. One specimen.
