Edwards, in his "Butterflies of North ; briefly des- cribes the egg and first larval instar of "Lciiioiiias" palmerii and shows figures of the egg and young larva. His illustration of the egg is somewhat misleading and does not conform to our observa- tions on the California race, uiargiiialis. Eight eggs of this species were secured from a female in cap- tivity, captured at Fish Springs, Imperial Valley, Calif., on (^ct. 25, 1931. These emerged on Nov. 4th. The eggs are probably deposited singly, on the young tender leaves of the food plant, Honey mesquite {Prosopis julifloria v. glandnlosa Cldl.). In cap- tivity the females laid on any variety of plant sup])lied them, but on emergence, fed only on the mesquite. 37.
