rufescent hairs, palest on the thighs; underside of the body flavescent. Varieties occur nearly one half smaller than the ordinary length, which often exceeds ten lines.

Its colonies are not so populous as those of B. terrestris, but they are more so than the associations of B. muscorum. Owing to the great difference in the markings, the male has been mistaken by Fabricius and others for a separate species, which he named B. arbustorum.
