The larvae are to be found in April, on Samhucus (Elder), each concealed separately in a rolled leaf, lined with silk. plant. Pupation takes place in a loose silken cocoon, on the food Pupa. Length, 20 mm. Color, dark mahogany. The form is robust, with the antennae and leg cases standing out as rounded eminences. The surface is granular, or pitted over the greater part of the chrysalis, and a few short setae are present
. Bulletin of the Southern California Academy of Sciences. Science; Natural history; Natural history. We hope at some later date to include notes on all of the larval instars. The larvae are to be found in April, on Samhucus (Elder), each concealed separately in a rolled leaf, lined with silk. plant. Pupation takes place in a loose silken cocoon, on the food Pupa. Length, 20 mm. Color, dark mahogany. The form is robust, with the antennae and leg cases standing out as rounded eminences. The surface is granular, or pitted over the greater part of the chrysalis, and a few short setae are present on por- tions of the body. The special features of the pupa are clearly shown in the illustrations on Plate 21, fig. C, and Plate 22. The imagos emerge from early May to late June in lower altitudes. Farther north, or in higher altitudes, their time of hatching may be delayed until as late as August. Holland states that the species ranges from northern Cali- fornia to British Columbia and eastward to Wyoming. We can extend that range to southern California. The imago is illustrated in Holland's Moth Book, Plate XXVH, fig. 2. His picture is of the green form from which was named viridula by Grote. The typical insect is PLATE 22 Pupa of Zotheca tranquilla, enlarged x 3. Ventral aspect. B. Lateral aspect. C. Dorsal aspect. Photographs by the late Wm. Menke 79.
