Reprinted with permission from: Mitchell, T.B. 1962 Bees of the Eastern United States. North Carolina Agricultural Experiment Station Technical Bulletin No. 152.
FEMALE—Length 8-11 mm.; lateral ocelli subequally distant from margin of vertex and each other; cheeks slightly narrower than eyes; longer side of basal segment of flagellum nearly equal to segment 2, median segments considerably longer than broad; mandibles with a distinct, inner, subapical tooth; wings subhyaline, becoming quite deeply infuscated along outer margin and in region of marginal cell, with the usual three submarginal cells, 2nd very broad and 3rd much constricted anteriorly, veins piceous, basal vein much basad of transverse median; tegulae shining between deep, distinct, and slightly separated punctures, these somewhat closer anteriorly and along inner margin; posterior margin of scutellum quite deeply grooved medially; front coxae simple; hind tibiae with 4 or 5 robust, elongate, dark, spine-like, apical setae; head and thorax red in large part, with black areas between and somewhat above antennae, in the ocellar triangle, on posterior half of cheeks, lateral and ventral portions of prothorax, a narrow median line on scutum, mid coxae, metapleura and adjacent area of propodeum, and median area of propodeal triangle; flagellum, tubercles, tegulae, and legs in part, somewhat more testaceous, spurs pale yellow; abdominal terga red in large part, basal tergum narrowly piceous at base, terga 2 and 3 with large, widely separated, bright yellow maculae; punctures of head and dorsum of thorax coarse, close, deep and distinct, somewhat more finely and closely so on scutellum and on cheeks below, very fine and close but quite distinct on clypeus; mesopleura rather coarsely rugoso-punctate, black areas of metapleura and propodeum somewhat more shallowly and obscurely rugose; basal area of terga 2-5 finely and very closely punctate, the apical impressed areas practically impunctate; pseudo-pygidium transverse, very narrow, forming the truncate apical margin of tergum 5; pubescence very short and inconspicuous, entirely pale, somewhat more copious on propodeum, pleura, cheeks and face.
DISTRIBUTION — Minnesota to Nova Scotia, south to North Carolina, May to July.
FLOWER RECORDS—Robertson (1929) records cuneata on Achillea, Arabis, Arunchus, Cercis, Claytonia, Dentaria, Dirca, Ellisia, Nothoscordum, Osmorrhiza, Rhamnus, Rhus, Ribes, Salix, Taenidia, Viburnum and Zanthoxylum.
It seems desirable to remove cuneata from synonymy with lepida Cresson because of the uncertainty with respect to this association of the sexes. Males which have been compared with the type of lepida have a somewhat different distribution from that of cuneata females in North Carolina, having been collected in the vicinity of Raleigh, in association with females which differ from cuneata. Females of cuneata have been collected only in the higher elevations, from 3,500 to 6,000 feet.

Female. Length 8mm.; mandibles bidentate; resembles N. bella but is smaller, with thorax trilineata. Head and thorax red, not coarsely punctured; white pubescence on cheeks and pleura long; a black dot on each side of clypeus the area about the insertion of antennae and ocelli black, a red spot on supralypeus; ociput black; antennae erruginou, fourth joint longer than third. Mesothorax trilineate, the middle band broad; scutellum and post-scutellum red, sutures black; pleura black above with a red spot, red below; metathorax with broad black bands at the sides and in the center; tegulae and tubercles ferruginous. Legs red; upper third of anterior and middle femora black beneath; pale-lumule distinct; basal nervure basad transverse medial nervure more than the length of the latter; third transverse cubital nervure strongly angulated in the middle.
