Since the issue of the Check List of N. A. Coleoptera by the late Mr. G. R. crotch, I have been asked by several persons interested in that branch of science, if I would advise them to change the labels in their collections in accordance with the nomenclature of several familiar genera as therein set forth. To all such applicants I have answered, that such changes are not expedient, unless they are fully, convinced of the propriety of admitting them. For my part, I considered them quite unnecessary, and still further, contrarry to the code of laws of nomenclature under which I supposed we were acting.

The opponents of the law of priority in nomenclature have taken occasion, both in England and America, to argue against the restoration of obsolete names, on the ground that the names enployed in my Catalogue of Diurnal Lepidoptera do not always harmonize with those used in Staudinger's Catalogue of European Lepidoptera.

In the preceding paper on this genus I mentioned that I had found the larva of this species mining the leaves of Ampelopsis QuinQuefolia. Since that paper was placed in the hands of the Editor, many months ago, I have succeeded in rearing it from the mine.
