I have received from that indefatigable explorer and naturalist, Mr. W. G. Wright, of San Bernardino, several examples of Lycœna Dœdalus, ♂ ♀. Up to this date the ♂, as described by Dr. Behr, has been unknown to me personally, and by all recent list makers has been set down as a synonym of Icaroides, Bois. Its female is Aehaja, Behr., also put down as a syn. of Sœpiolus, or rather es one of the dimorphic forms of the female of that species.

Mr. Wright made the ascent of one of the lofty mountains in that region, and says: “Saw nothing on the way up, except that at the camping halfway place were a few of these Lycœnœ and a Grapta. Next day, on going up to the high crest, it was a little cloudy, but not very cold (50° probably), yet not one butterfly was seen during the entire day, though I stayed on the crest, 11,550 feet, several hours.

Dr. Hagen, in his paper on the genus Colias, recently published, discussing the species described by Mr. Wm. H. Edwards under the name of C. Christina, comes to the conclusion that it is merely a variety of C. Edwardsii, which he regards as only a form of C. Interior, Scud., including also under the latter name. Emilia, Astrœa, Scudderi, Alexandra, Occidentalis, Harfordii and Laurentina.

Egg.—Diameter, .06 inch. Shape spheroidal, the transverse diameter being about one fifth more than the longitudinal; striated longitudinally with 28 striæ, 15 of these reaching the shallowly punctured apex, these ridges being crossed with a network of slight elevations, the transverse and the longitudinal lines in the middle of the hollows making squares, the interior of these squares being roughened, the corner of each square a little more elevated and enlarged than the sides. Color brownish olive. Duration of this period 234 days.

Young Larva.—Length .25 inch. Color pale gray, one prominent purplish black dorsal line and three less distinct lines on each side. Head purplish black, piliferous spots and hairs the same color. Venter paler than above, with a dark spot in the centre of each joint. Feet, 12. Duration of this period 6 to 7 days.

On the 22nd of August, 1882, while entomologizing along the border of a wood at Oak Hill, New York, I was agreeably surprised by a call from a lady companion—an earnest devotee of the floral kingdom, who was but a few yards distant in the pursuit of her favorite study—that she had discovered something which she appeared to regard with that sort of honor which one might bestow on a venemous reptile. Knowing her dislike of all crawling things, I at once conjectured that the cause of the alarm was a spinous caterpillar, and that my attention, no, doubt, was being directed to that over which I at least would be enthusiastic. It proved to be the formidable looking larva of this moth, popularly known as the Hickory Horned Devil, and on account of its rarity, a goodly, and in no sense an evil sight to a naturalist. It was found feeding on the hickory. It burrowed a few inches into the earth on the 19th of September, to transform, and two days thereafter the pupa worked itself to the surface.
