If it were necessary to emphasize the need of revision in the Geometrina, the genus Venusia furnishes an excellent example. It has established by Curtis, an English writer, in 1839, with cambrica, Curt., as its type. Since that time, three additional species, according to Mr. Meyrick, from New Zealand have been placed under it. In our own fauna, Dr. Hulst placed three species as its representatives—cambrica, Curt., comptara, Walk., duodecimlineata, Pack.
