Just about the time the lilac bushes open their fragrant blossoms the grand insect shown at figure 9 may be seen either hovering over gardens and sipping the nectar of flowers, or sailing majestically down some woodland glade. It generally appears at Ottawa about the first of June, and may be seen for a month or more. Farther to the north it comes later, not appearing at Nepigon, north of Lake Superior, until the end of June. This insect has many characters which make it of interest to the collector.

At different times, in making notes for a general list of our Lepidoptera, I have taken up the arrangement of our butterflies, and, although such a list must now be undertaken by some one else, I think it worth while to set down the conclusions to which I had come.

As far as I am aware no description of the larva, of this insect has been published, and hence I present the following:-

T. pudens.—Mature larva. Head white, with four black spots, two covering the eyes and the others near the summit of the head. A few short, whitish hairs. Body semitransparent, whitish, flecked with opaque white spots on the dorsum and more thinly on the venter. Stigmatal space covered by a blackish shading, more distinct anteriorly; a darker dorsal line. Spriacles pale brown. Cervical spot whitish, concolorous with body. A few short pale hairs.

Egg.—Diameter .03 inch. Globular, smooth. Color whitish, with a pearly lustre. Duration of this period here four days, in the mountains of California six days.

Young Larva.—Length .07 inch. Cylindrical, six rows of tubercles from which spring hairs as long as the body. Color pale gary, head black, hairs gray. Duration of this period four days.

As the descriptions are short and so generally unknown, I will reproduce them here:-

“Var, hybrida: Primaries of D. bella, but the yellow belts indistinct, secondaries of typical D. ornatrix, but with the ground colour red as in D. bella, and with a white edged, interrupted black belt across the discoidal cell.

will hold its first annual meeting in the City of Washington, D.C. on November 12th, 1889, at 11 o' a.m., in the Entomoloigcal rooms at the U.S. National Museum.

According to the resolution of the Association at the Toronto meeting, the annual meeting was to be held on the date and at the place where the Association of Agricultural Colleges and Experiment Stations should nex meet.
