In reference to recent “protest” in the pages of the CAN. ENT. (Vol. XXXIII., p. 263) against a change in the generic name Eupethecia, I believe its abandonment, in favour of a Hübnerian name chosen cut of the Verzeichniss by Mr. Meyrick, to be invalid. I retain it myself in the collection here for the reason that its date is certain, and there is a rule of the German zoological code that if exact dates cannot be ascertained (and this is the case for that part of the Verzeichniss which contains the Geometrids), preference shall be given to the genus which has a type cited. This is reasonable, and custom has correctly sanctioned the use of Eupethecia. I an indebted to Mr. L.B. Prout, of London, England, for the information that Curtis himself, in founding the genus Eupethecia, explicitly chooses absinthiata, L., as type of the genus, April 1, 1825. In my study of the Geometrid genera (1895–96), only a fragment of which appeared in the Transcations of the Entomological society of London, I pointed out some of the errors into which I have reason to believe Mr. Meyrick has fallen.
