To one familiar with the locality, --a surface almost completely strewn with angular rock fragments, --Mr. Sanborn's exploration will seem to have been a very successful one. Most of his specimens were found at more than a mile from the summit; doubtless better success would attend efforts in localities not more than half or three quarters of a mile from the top. One would suppose that insects, whose home is almost always swept by the fiercest blasts, would be provided with powerful wings fitting them for strong and sustained flight; but the contrary is true. They can offer no resistance to the winds, and whenever they ascend more than their accustomed two or three feet above the surface of the ground, or pass the shelter of some projecting ledge of rocks, they are whirled headlong to immense distances, until they can again hug the earth. Their flight is sluggish and heavy, and has less of the dancing movement than one is accustomed to see in the Oreades. They are easily captured. The European Aello appears, says Meyer-Diir, among the earliest butterflies of the Alps. It is seen soon after the snow melts, --first, on the lower grounds at the end of May; last, on the higher levels (corresponding more nearly to those to which our species is restricted) at about the beginning of July; it disappears in the same way from the end of June to the end of the first week in August. 2.
