I have been collecting Lepidoptera in Orillia and its vicinity for over thirty years, off and on, and thinking that it would be of interest to my brother collectors to have an idea of the fauna of this district, I send you a list of the diurnal Lepidoptera taken by me as far as identified.

In Part IX. of the 3rd series of Edwards's Butterflies of North America is given a very full and beautifully illustrated history of this species from the egg to imago; but as I have bred this species during the summer of 1895, through all its stages, and as the life-history, as worked out by me, differs in certain important particulars from that recorded by Mr. Edwards, I think it advisable that I should give my experience in the rearing of this very interesting species.

At the eighth annual meeting of the Association of Economic Entomologists, held at Buffalo, August 21st and 22nd, 1896, a part of one session was devoted to the consideration of the work of exterminating the gypsy moth in the Commonwealth of Massachusetts. The subject was presented for discussion by the President, Prof. C. H. Fernald, at the morning session of the second day. Prof. Fernald referred to the action of the Association at its Springfield (1895) meeting, and stated that at the legislative hearings of the past spring, held with reference to determining the size of the appropriation to be granted for continuing the work of exterminating the gypsy moth, no representations made by the Gypsy Moth Committee, the Director, or himself, carried a fraction of the weight that the endorsement of the Association afforded. The legislators recognized the Association as a body of eminent scientists, and accordingly valued the opinion of its members.

The two following descriptions were intended to be included in articles discussing at some length the Nomada, spp , of New Mexico, and certain Mutillidæ; but poor health having caused these to be indefinitely postponed, the descriptions are presented herewith.
