Some of the generic names used for Scatophagid♀ will stand of fall according to one's notion of homonymy. Becker, in 1894, proposed the name Orthacheta (cf. Inded Zoologicus); Aldrich, in the interest of orthography, has altered this (Cat. N. A. Diptera) to Orthochœta. Now, Germar long ago used Orthochœtes for a beetle, while Cossmann, in 1890, used Orthochetus for a mollusc. I do not pretend to say what ought to be done with such a mix-up; it comes back to the old question, whether an error in spelling (which may hypothetically be attributed to the printer) must be maintained; and again, if not, whether the differences in the termination suffice to prevent homonymy.
