. Annual report. 1st-12th, 1867-1878. Geology. 708 REPORT UNITED STATES GEOLOGICAL Fig. 7.—a, male moth; 6, abdomen of female—natural size; c, eye; d, base of male antennas; e. base of female antenna; enlarged.—(After Eiley.) thread-like liues: while the upper part is dark, with an interrupted white thread running exactly through the middle of the back. The prolega, ten in number, are i marked on their outer middle and \ on their tip with black. Beneath, ; the caterpillar is of a livid green, i Most of the Maine species of Leu- cania have light-colored wings, with dark streaks and dots, but the uni- punota is larger and darker colored. Its prevailing hues are rusty gray- ish-brown, sprinkled or peppered sparsely with black scales. The upper part of the head, the front part of the thorax or collar, and front margin of the fore wing, are of a lighter shade. Between the front margin of the fore wing and the vein, or raised line reaching out to the white spot in the center, is a rusty patch. Just beyond, about half-way between the white dot and the outer edge, is a row of about ten black dots, situated on the veins, running toward the apex of the wing, but the last three are deflected at a right angle inward and up to the front margin, while a dark line starts from the corner or curve in the line of dots, and proceeds to the upper angle or apex of the wing. The little veins of the outer edge are silvery, and between them, in a row next to the fringe, can just be seen little black dots. ' The hind wings are pearly smoke-colored, darker toward the outer edge, with a central spot of the same color, which can be seen on the under side. Beneath, the moth is a light pearly-gray. The fore wings are clouded in the middle, with a dark spot on the front margin, one-fourth of the way from the tip. The fore wings are rather more pointed in this species than the other. The body measures nearly an inch long, and the wings exxDand a little over an inch and one-half. Sum
