Cerylonidae is a family of beetles, in the suborder Polyphaga.The Cerylonidae are a family of small to minute beetles (usually 2 mm. 01- less) which occur most commonly in forest litter and under bark. At present, there are about 40 genera and over 300 described species known from all of the major zoogeographic regions. Crowson (1955) first recognized the Cerylonidae as an independent clavicorn family, including the cerylonines and murmidiines, as well as Euxes- tus and its allies; but these groups have been treated as tribes of the heteromerous family Colydiidae by both Hetschko (1930) and Ar- nett (1968). In their world generic revision of the family, Sen Gupta and 'Crowson (1973) added Anommatus Wesmael, Abromus Reitter, and Ostomopsis Scott, while transferring Eidoreus Sharp (== Eupsilob'ws Casey) to the Endomychidae. The present paper consists of a revision of the 10 genera and 18 species of Cerylonidae occurring in America north of Mexico. With respect to the compo- sition of the family and that of its major subordinate groups, we have followed the classification presented by Sen Gupta and Crowson; the interrelationships among the subgroups, however, are still obscure, so we have treated the Euxestinae, Anommatinae, Metaceqloninae (not North American), Murrnidiinae, Ostomopsinae, and Cerylon- inae as independent subfamilies. The following abbreviations have been used in keys and descrip- tions: PL - pronotal length, PW - pronotal width, EL - elytral length, EW - elytral width, and TL -sum of PL and EL. The word "length" refers to the total length, including the head, and is 'Published with the aid of a grant from the Museum of Comparative Zoology.
