A. fulvipennis is not closely related to any of the foregoing species. It is, perhaps, most closely related to a group of Callandrena occurring chiefly in Mexico and Central America but including a few forms in southern and eastern United States, such as A. duplicata Mitchell and A. simulata Smith. A. fulvipennis is marked by the following combination of characters: wings deeply infumate, brown; hind tibiae and basal portions of basitarsi yellow to red1 dish-yellow; claws of hind legs of the female reduced; basoventral angle of mandible well developed. A. fulvipennis can be distinguished from duplicata, simulata and related forms by the clypeus being evenly rounded or with a low longitudinal median ridge, not markedly flattened medially, and by being generally less coarsely punctate.

TYPE MATERIAL. — The holotype female of fulvipennis from North America is in the collection of the British Museum (Natural History), London, England.
DISTRIBUTION. — This species is known to occur along the east coast from Florida north to New Jersey and in eastern Texas (Fig. 13). It probably occurs in Alabama, Mississippi and Louisiana, but has not been recorded from these states as yet. It has been collected from July 5th through December 11th, but chiefly in September and October. The author has not seen the holotype but has examined specimens compared with the type by T. D. A. Cockerell and by T. B. Mitchell. A total of 52 females and 42 males have been examined from localities listed below.

FLORAL RECORDS. — A. fulvipennis seems to be an oligolege of the Compositae. No further statement of flower preferences is possible from the data now available. Eight collections of eleven specimens indicate that these bees have been collected visiting flowers of the following plants.
Aster sp., Chrysopsis sp., C. mariana, Haplopappus sp., Heterotheca latifolia, H. subaxillaris, Gutierrezia texana.
