[Taxacom] possible genus homonym nomenclatural question

[David Campbell]

Based on  https://www.biodiversitylibrary.org/item/120189#page/25/mode/1up   ,
Walker seems to just be citing Hübner and doesn't seem to indicate any
intent to make a change.  The citation is just "Calymna, p. Hubn. Verz.
Schmett. 281.  " (as a synonym).  If lepidopterists know that Walker was in
the habit of "correcting" names, that would complicate things.
