when the descriptions of these species were prepared, I had forgotten that species had previously been described in Europe as G. juglandiella and H. evonymella. I have not seen these European species nor even any description of them, and possibly my species may prove to be the same. At any rate the names are so nearly the same as to necessitate a change of those, my species, and I therefore name them respectively G. juglandisnigrella and H. orbimaculella.
