American students have long used the name Thermonectes Crotch, 1873 (Trans. Amer. Ent. Soc., 4:402), for a genus of dytiscid beetles, and have accepted Crotch's designation of Acilius ornaticollis Aubé, 1838, as the genotype. This treatment overlooks three earlier references which establish a generic name for the same natural group of species.
