1. M. Brucei.

Male.—Expands from 1.5 to 1.7 inch. Upper side brown-black, marked with spots of red and yellow in transverse bands; there are three well marked varieties, in one of which red predominates, sometimes almost to the exclusion of yellow; in another red and yellow, much as in other allied species; on the third much yellow, very little red; in all the spots are small, so that the black surface is more exposed than in many species.

Now that the observations of my yound friend, W. D. Marsh, on this species, have been given in the Can. Ent. (xx., p. 45), I think no reasonable person can dubt that it is at least three-brooded in New England, and that the late butterflies hibernate there. Very late in the fall of 1887, Mr. Marsh saw individuals flying, long after severe frosts had been felt, and still later, he had butterflies come from pupæ. These late fliers are the hibernators.

In studying the seasonal variation exhibited by various species of butterflies, I have been struck by the fact, that whereas in most instances the form emerging in the spring is darker and smaller than the summer brood, there are also exceptions to this rule, in which the vernal emergence is the lighter. Take, for instance, the genus Pieris. The vernal broods of P. napi and P. protodice are distinctly more dusky than those which have undergone their whole metamorphosis in a single season; but, on the other hand, the spring emergences of P. rapœ and P.brassicœ are wont to be pale, and the spring-emerging P. virginiensis is pale, and as Mr. W. H. Edwards remarks (“Papilio,” 1881, p. 97), more like the summer than the winter form of tis progenitor P. napi.

It was my privilege last summer to accompany the expedition sent out by the National Academy and the U.S. Navy Department to Japan for the purpose of observing the total eclipse of the sun which took place upon the 19th of August, 1887. The route selected by our party was the one just opened to the far East over the Canadian Pacific R.R., and I was the first passenger booked in Chicago for Yokohama, and my coleague, Prof. Todd, was the first passenger booked in Boston for the same port, over the new line.

8. Brachynemurus Carrizonus Hag., n. sp.

Yellow with black lines; face yellow, above with a transversal narrow black band, separated by a yellow crescent from the antennæ, and by a narrow yellow line between the antennæ from the vertex; a faint median black line goes from the black band nearly to the clypeus; labrum yellow; palpi short, pale yellowish, maxillary with apical joint, cylindircal, black except on tip, the two preceding joints with a brownish mark in the middle; labials a little longer, apical joint hirsute, black shining except on base, fusiform, thichened, the apical third thin, pointed; on the inflated part an ocelius like spot.

This is in California the first buttefly to emerge in the spring, appearing in Feburary, though it is accepted representative of the Eastern Neglecta, which is not the first to appear there. Piasus is double brooded; the second brood coming in the latter part of April, and between it and the first brood a few days intervene when no Piasus are seen. Both broods are very fond of water, being always found on damp sands of wet places, and at the bookside crossings.
