Identification
Extracted from: Charles Robertson (1900). Some Illinois Bees. Trans. Acad. Sci. Of st. Louis.

Female. Related to and closely resembling M. communis Cr., but is somehwat smaller and the mesonotum and scutellum are without black pubescence. Also resembles m. comptoides, but the pubescence is less fulvous aboce, and not dark on the thorax beneath, the front and middle legs, and the hind metatarsi beneath. Length 9-11 mm.
