MALE�Length 8 mm.; length of face slightly exceeding greatest width; eyes moderately convergent below; length of malar space nearly half its breadth; antennae blackish, median segments only slightly longer than broad, basal segment about as long as broad, slightly exceeding pedicel; clypeus flattened, densely tessellate, punctures shallow and obscure; pubescence short, thin, greyish-white on head and thorax, with a slight amount of fuscous admixture on dorsum of thorax; lateral angles of pronotum acute but hardly spine-like; metapleural protuberance not carinate; tegulae piceous; wings hyaline, slightly violaceous, veins and stigma brownish-testaceous; punctures of scutum coarse and deep, close anteriorly, becoming sparse in center posteriorly, intervening areas shining; punctures of scutellum more coarse, irregular, not crowded, those on pleura coarse, deep and very close; upper surface of propodeum with a series of shining pits separated by short striae; tarsi dark, hind basitarsi about three times longer than broad, parallel-sided, fore and mid metatarsi slender; spurs yellowish; punctures of abdominal terga fine, close, deep and distinct, apical margins slightly depressed beneath the entire, white, apical fasciae; discal pubescence short, thin, brownish. DISTRIBUTION�Florida to Illinois and New York; April, May and June. According to Stephen the range extends northward to Nova Scotia and west to Utah. FLOWER RECORDS�This has been collected in North Carolina on Toxicodendron, and in Florida on Melilotus alba and Physalis elliottii. Other records given by Stephen are Monarda punctata occidentalis, Physalis lanceolata, P. virginiana. and Psoralea tenuiflora. Robertson (1929) lists also Ceanothus americanus, Pycnanthemum flexuosum and Rhus glabra. Identification Extracted from: Charles, R. (1895). Notes on bees, with Descriptions of New Species. Transactions of the American Entomological Society Vol. 22, No. 2. pp. 115-128. The ♂ closely resembles the ♀ . This is a little smaller than C. latitarsis Rob. and may be distinguished by the hind tarsi being much more slender.
