Four examples carried through to pupation, of which three emerged on the following dates: July 31. August 23 and August 26, 1947. The fourth specimen is still viable in July, 1948. As no record of the earlv stages of this rare moth has been published to date it may be helpful to report such fragmentary notes as we have on its metamorphosis. The foodplant grows closely appressed to the ground in areas of former clearings, and the larva being predominantly green is difficult to PLATE 10 Mature larva of Arctonotus terlootii. enlarged X approx. Drawing- by John A. Comstock Mature Larva: Length, 65 mm. Color, predominantly light green, the abdominal surface slightly lighter than the dorsum. Head slightly darker than the body. Ocelli, dark brown. An- tennae, bright green at the base, yellowish on terminal segments. ]\Iouthparts, translucent, very light green, the mandibles edged with dark brown. ]vlinute white hairs sparingly cover the head. The dorsal area of the body is covered with minute round orange spots, each of which is marked in the center with a yellow dot bearing a short yellow hair. These orange spots are discernible with a hand lens. They are arranged in transverse rows, and tend to fade out in the area below the spiracles. These spots disappear in alcoholic specimens. There is a slight suggestion of a longitudinal light band above the spiracles. Caudal horn, short, and tinged with yellow. Spiracles dark brown, margined with black, surmounted by a blue lunule and edged posteriorly with a dark brown shading. 50. Please note that these images are extracted from sca
