Cassida azurea Fab. was incorrectly identified as C. hemisphaerica Hbst. in the paper entitled “Biology of the tortoise beetle, Cassida hemisphaerica (Coleoptera: Chrysomelidae), a possible biological control agent for bladder campion, Silene cucubalus (Caryophyllaceae), in Canada”, Can. Ent. 108: 945–954, 1976. Thus, all references to C. hemisphaerica in that paper, with the exception of those in sections Geographic Distribution and Recorded Host Plants, should read C. azurea.
