In the present unsatisfactory state of our knowledge of American Tineina it is of little value (or worse) to describe promiscuously new species from collected material, difficult of subsecjuent recognition. No one is any the better off because he learns that such and such a new species of Geleciiia or LitJiocoIletis has been taken in such and such a locality. Only when working up a group, either faunistic, or preferably systematic, does it seem to me excusable at present to de-scribe more species, which are known from the type specimen only. Exceptions may be made in the case of new generic forms or espe-cially striking or otherwise interesting species. I believe anyone will endorse this view who has tried to grope through Chambers' flood of descriptions, many of which represent only valueless names, a dead weight on our lists, and which will not for a long time, if ever again, be connected with the species they represent. But as it will take years before the American Tineina fauna can be worked up systematically by groups, which is the end for which we should strive, it does not seem desirable in the meanwhile to withhold from publication new forms, of which the life history has been ascertained and which are of such interest as to be of some positive gain to our knowledge. And here I might point out an opportunity for any student, who has not the facilities or the desire to do systematic work, but who still
