When I decided on an Entomological tour during the past summer to the Island of Anticosti and the coast of Labrador, I fully expected to bring home sufficient material, not only to satisfy the few subscribers to the enterprise, but (after supplying them) enough to remunerate myself for the risk of the voyage and loss of time. Your readers are already acquainted with my misfortune ; still, I hope that the lost species will be replaced, as it is my intention to go over the ground again (if God spares me) next summer. Entomologically speaking, the region is totally new.

The former description of this species was made from a single old specimen, on which no tufts were visible (having no doubt, been removed in setting the specimen, which was, however, otherwise undenuded.) Since the publication of that description, I have bred the species, and the tufts in the fresh specimen are distinct, and the insect unquestionably belongs to this genus. The following description of the fresh specimen is more accurate than the preceding one. I have changed the specific name, giving it that of the food-plant.

The geographical distribution of Smicra differs much from that of Leucospis. Unlike the latter genus, which is spread thinly and somewhat equally over the warm and temperate regions of the earth, Smicra, with very few exceptions, is limited to the New World, where there are some species in North America, many in Mexico and in the West Indies, and great abundance in the tropical parts of South America, and the genus has thus much more influence than Leucospis in regulating, by means of transfer, the increase of other insect tribes.

We have here before us a paper by an accomplished scholar, on a Subject dear to us from our own studies. Mr. Scudder's Revision presents two main points for our consideration. The first pont affects the sequence of the Butterflies in a systematic arrangement ; the second the application; of the scientific law of priority.. As to the first, the consideration which have influenced Mr. Scudder to side rather with Oschsenheimer than with Boisduval, where the present Revision is not original, are evidently not lightly taken.

While in the Catskill Mountains this summer, I met with a very curious variety of L. Misippus in which the conspicuous black stripe crossing the secondaries was altogether absent, and the corresponding mark on the primaries only indicated by a dusky cloud extending to the median nervule and enclosing no white spots. On the underside the differences remain the same. In the ordinary type, there is a whitish cloud around the cross stripe.

Male expands 1.3 inches. Al1 the wings dark brown above. The primaries throughout the middle and basal areas sparingly sprinkled with fulvous scales. This color is deepest around the stigma, which consists of a velvety black bar extending obliquely from near the middle of the submedian vein to the cell, and is often divided into two equal parts by the fourth median veinlet. A large square patch, not sprinkled with fulvous, occurs in the middle area at the termination of the cell ; and a small detached yellow spot lies immidiately below, and outward from the anterior termination of the stigma.
