The egg of this species was illustrated and described in the Bulletin Southern Calif. Academy of Sciences, Vol. XXIX, Part 1, 1930. p. 23. We are reprinting this illustration on Plate 27, fig. a. Eggs were collected on May 1 of this year, and larvae emerged May 11. Again on May 15 eggs were laid which hatched on the 23rd. A third group of eggs which were deposited July 17 emerged on the 26th. The duration in ovum therefore is from 8 to 10 days. The female deposits her eggs singly on the leaves of At rip} ex (Saltbush). LARVA, first instar. Color, bluish green. The usual four rows of long white slightly recurved hairs occur, in longitudinal arrangement. There is a sub-dorsal line of black dots, one to each seg- ment. A similar line also is placed immediately superior to the lateral row of hairs. Head black. In successive instars the color is variable, with the predominant type a pale blue-gray, and the surface is covered with a whitish pile. There is a mid - dorsal band of speckled light brown, and a similarly colored though less clearly defined lateral band in which the spots run diago- nally across each segment. The first and caudal segments are speckled with black. On the 11th segment there is a laterally placed retractile organ which, when fully protruded, liears a series of orange points in stellate arrangement on the tip. The illustration, Plate 27. fig. b, shows this organ in full extension. Abdomen, pale gray-green. Legs, pale blue - gray, with brown tips. Prolegs concolorous with abdomen. Spiracles black. Head black, and retractile. ^ Mature larva. Length when a. Egg of Plebejus r n . i i i ^ ^ i c ci emigdionis Grin, magni- ^"">' extended, 13 to 15 mm Slug tied X 45. shaped.
