A Review of the Beetle Family Cephaloidae
The family Cephaloidae consists of only one genus, Cephaloon Newman, 1838, with eight known species that are locally rather common but are known only from the Eastern United States, Western United States, Western Canada, Japan, and Amur. All of the species are closely related and quite variable in color. Useful separation characters are to be found in the antennae and various male structures. As yet little is known concerning the habits and life histories of members of this group. All known species of this family are represented in the collections of the U.S. National Museum.
