DISTRIBUTION�Illinois to Massachusetts, south to Florida, March to June.

Black; head and thorax densely and con
fluently punctured, thickly clothed with short pale pubescence; sides of face,
clypeus. spot above, labrum, mandibles except tips, dot at summit of eyes,
posterior orbits, scape beneath, collar, tubercles, tegula, scutellums, spot on
