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.

FEMALE. MEASUREMENTS AND RATIOS. N = 20; length, 9-11 mm; width, 2.5-3.0 mm; wing length, M = 3.73 0.125 mm; FL/FW, M = 1.10 0.008; FOVL/FOVW, M = 2.99 0.034.

INTEGUMENTAL COLOR. Black except as follows: mandible with apical one-third to one-half rufescent; flagellar segments 4-10 dull red or brown below; wing membranes deeply infumate, dark brown, especially near anterior margins, veins brown to red, pterostigma and prestigma usually yellowish-red; terga 1-4 with narrow apical margins hyaline, colorless, rufescent basad of hyaline area; sterna 2-5 with extremely narrow apical margins hyaline, colorless, rufescent basally; distitarsi usually rufescent; hind basitarsus with basal third to half yellow or reddish-yellow; hind tibiae yellow to reddish-yellow; tibial spurs yellow.

STRUCTURE. Antennae short; scape equal in length to slightly more than flagellar segments 1-13; flagellar segment 1 equal in length to somewhat less than segments 2-4; segment 2 about equal in length to 3, each distinctly shorter than segment 4; segments 4-7 subquadrate to quadrate, 8-10 longer than broad. Eye about three and three-fourths as long as broad, inner margins converging slightly towards mandibles. Malar space linear. Mandibles long, outer mandible in repose extending beyond middle of labrum by one-third to one-fourth its length; basoventral angle well developed, with a narrow lamella, broadest width of mandible (at angle) slightly more than twice minimum width; subgenal coronet well developed but hairs slender and barbed rather than stout and spine-like. Galea evenly rounded from dorsum to side, side about one-third as broad as dorsum; surface dulled by fine regular tessellation, punctures obscure; covered with relatively long, moderately abundant, erect, white hairs. Maxillary palpus short, not reaching apex of galea when extended forward, segmental ratio about 1.0:1.1:0.7:0.7:0.6:0.9. Labial palpus with first segment long, slightly curved especially along inner margin, apex broadened and flattened; segmental ratio about 1.6:1.2:0.6:1.0. Labral process short, sharply bidentate. Clypeus protruding beyond tips of compound eyes by slightly more than one-fourth its median length, evenly rounded or often with slightly longitudinal impunctate ridge especially in basal half; punctures small round, separated by one-half to one puncture width medially, becoming smaller peripherally, surface moderately dulled by regular reticular shagreening. Supraclypeal area with small crowded punctures and reticular shagreening dulling surface. Genal area about as broad as eye in profile or slightly narrower; punctures minute, separated mostly by two or more puncture widths, surface shiny near eye margin, moderately dulled by reticular shagreening elsewhere. Vertex short, above lateral ocellus equal to one ocellar diameter or slightly less (at shortest about 1.1:1.4); with crowded punctures above ocelli, with scattered punctures above foveae and compound eyes, surface dulled by coarse reticular shagreening. Face Above antennal fossae with longitudinal rugulae, interrugal spaces sparsely punctured and shiny, weakly shagreened, rugulae extend between lateral ocellus and fovea and above fovea half distance to compound eye. Facial fovea long, shallow, extending down to level of lower margin antennal fossa or slightly more, lower end slightly narrower than upper, rounded, upper end rounded, separated from lateral ocellus by at least three-fourths of an ocellar diameter.

Pronotum normal, with scattered punctures, surface moderately dulled by coarse reticular shagreening. Mesoscutum and scutellum with distinct round punctures irregularly spaced mostly by one to three puncture widths, surface moderately dulled by coarse tessellation; parapsidal lines short, about as long as from its lower end to margin of scutum. Metascutum opaque, with contiguous, coarse punctures. Tegulae normal, impunctate.

Fore wing with three submarginal cells, second submarginal cell receiving vein 1st m-cu near or beyond middle of cell; cell along posterior margin equal in length to somewhat more than half length of first cell; pterostigma broad, slightly broader than from inner margin pterostigma to wing margin. Claws of hind tarsi reduced; slightly smaller than claws of middle and fore tarsi; tibial spurs normal.

Metasomal terga 1-4 opaque, coarsely, regularly and densely tessellate, bottoms of tessellations and intertessellar ridges often with one to two fine reticulations under high power magnification. Pygidial plate broad, V-shaped with rounded apex, margin reflexed, without central triangular raised area, shiny unless worn. Sterna 2-5 with apical margins impunctate, basally with small punctures separated by 3-4 puncture widths but more crowded near impunctate apex, surfaces moderately dulled by reticular shagreening.

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.

FLORIDA: Lake Worth; Panama City. GEORGIA: Fort Gordon, Richmond Co.; Griffin; Roberts; Tallulah Falls; Tifton. MARYLAND: Blandensburg. NEW JERSEY: Anglesis; Clementon; Lakehurst; Lebanon State Forest, Ocean Co.; Lucaston; Palmyra; Sea Isle City. NEW YORK: Southold, Long Island. NORTH CAROLINA: Catherine Lake, Onslow Co.; Cherry Point; Holly Shelter; Kill Devil Hills; New River; Southern Pines; Swannanoa; Tarboro. SOUTH CAROLINA: Myrtle Beach. TEXAS: Brazos Co.; Fairfield (14.5 miles S.); Jacksonville; Nacogdoches; Newton (2 miles W.); Somerset.

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.
