Fifth report of the United States Entomological Commission, being a revised and enlarged edition of Bulletin no7, on insects injurious to forest and shade trees . e catenaria (Drury).(Larva, Plate xxxii; figs. 3, 3a, 3b, 3c.) What was without much doubt a belated caterpillar of this specieawas fouud on the white pine October 5, but the body was not soclear a yellow, and the two black spots on the side of each segmentwere not well defined. A chrysalis was also beaten out of a pitch pineAugust 31; another out of a hackmatack August 30. The moths fromthese chrysalids appeared September 15 and 16. From these facts Ithink this caterpillar occasionally at least feeds upon different conifer-ous trees. Its food plants, however, are the blackberry, woodwax, andwild indigo, though in Maine I have found it most abundant on Carexpennsylvanica. Larva.—Head as wide as the prothorax, full, roundeU, distinctly bilobed, ash-brown,finely dotted with dark, and with six to seven large black dots on each side. Body a little thicker at first abdominal feet than elsewhere; the body slightlywidening towards this point; it is cylindrical, the segments wrinkled Fig. 267.—Zerene catenaria.—e, male; d, female; a, larva; b, pupa—all natnral size. From Riley. The body is above and as a ground color a light yellowish ocher-brown, withyellow-ocher patches here and there ; with broken, fine lines, one pair on eachside dilating on the back of each segment into a minute black dot, one behind the 784 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. other. A broad lateral flesh-colored band containing the large black conspicuousspiracles, four to five broken black lines, the uppermost black lines being heaviest. Beneath greenish yellovr, with six broven hair lines. Supra-anal plate broad, trian-gular, apex pointed, but somewhat obtuse. Length, 30™™.
