In Vol. 4, p. 137, of the Canadian Entomologist, Mr. Grote first published a description of the large and characteristic Tineid above named. The imago has been very common with us for several years, but until the present season its larval history had eluded my investigation.

Early in April I found among the roots of a bit of white clover sod a very active and singular larva, whose long and rather sprangling thoracic legs gave it, at first glance, the appearance of a Coleopterous larva. A second look, however, discovered the characteristics of a Lepidopteron of which the following description was taken:

Length, 0.75 inch.; diameter greatest at head and 1st joint, slightly tapering thence posteriorly.

There will hardly be a naturalist who has not spent considerable time to study the questions–What is a genus, and what are generic characters? Indeed, work is nearly impossible without having taken a position with regard to these questions. A full record of the literature, even the most condensed one, would be here out of p1ace, but I have been induced by a recent and most surprising discovery bearing upon this question to make this communication.
