Nitzschian species Docophorus atratus, Nirmus varius, and Menopon 
mesoleucum are identical. It need hardly be said that any conclusion 
based upon such a premiss does not demand serious consideration. 
Moreover, among the species included by Degeer in Ricinus, there is 
not a single species of what is now Degeeriella.
