As a result of breeding carried on in the course of Insect Faunal Survey in the Maritime Provinces, combined with a study of genitalic characters, it has been found that the present application of names, especially in the alnivorella group and the so-called “red-winged forms”, is very faulty. More species, similar in general appearance but easily differrentiated on male genital characters, have been found to occur than has been previously supposed; it is with a view of straightening out the nomenclature that the following notes have been prepared.
