The species considered below are those which are listed in Leiodes in the Leng Catalogue of Coleoptera and which were treated under the name Liodes by Horn (1880, Trans. Am. Ent. Soc. VIII, 296). Since the appearance of Horn's synopsis, they have been neglected, and only one species, interstrialis Hatch, has been described. In the following synopsis, three species are described as new, several changes in nomenclature are suggested, and a number of important characters not noted by Horn are described.
