HesPeria mystic, Edw.–Two eggs were deposited by a beaten female in a pill box, on the 20th of June, colour pale yellowish green: strongly convex above, flattened below, and depressed or slightly concave in the centre of the flattened portion. The surface appears smooth under a magnifying power of forty.five diameters, whereas in those of Hobomok, reticulations are plainly seen under a power of twenty. The egg of Mystic appears faintly reticulate under a power of eighty diameters. One specimen produced the larva on the 28th, the other on the 29th.

Pepilio Asterias, Fab.—A specimen of this butterfly was seen by me at Natashquaun on the 24th June. On the 4th July I found it common at a place further down the coast, called Musquaro. The same species occurs in Newfoundland.

Pieris Frigida, Scudder.—This butterfly is common at Natashquaun, where it appears about the 15th June. I am of opinion that it is doublebrooded, as I noticed fresh specimens on my return to Mingan on the 16th July. It occurs on the whole of the south as well as the eastern coast of Labrador, where Mr. Scudder procured the species.
