Included in this family are short, very convex beetles of small or medium size, having the upper surface more or less clothed or ornamented with hairs or minute scales. The legs of most of the species are very contractile, being capable of being folded up so closely against the body that it is with difficulty that they can be seen. The name Byrrlius, that of the typical genus to which the larger species belong, is derived from the Greek word "bursa," a "hide," and was given the genus by Linnfeus, probably on account of some fancied resemblance in texture of their upper surface. He also gave the specific name iiiliihis, meaning "a little pill," to a European species, on account of its resemblance to a pill or little ball, and the name "pill-beetle" has been since applied to the mem- bers of the family.
