Dammers Strymon auretorum spadix Hy. Edw. This Initterfly has, until recently, been considered one of our rare species. Rarity, however, seems largely a question of time and place. If one finds the real metr()])olis of a species, at a time when climatic and thermal conditions are at their best, that species will appear in abundance. This was demonstrated in July (jf 1933, when the junior author found an immense colony of 6". spadix on the wing, in the oak belt, at the to]) of Cajon Pass in the San Bernardino Moun- tains. A search in this region led to the discovery of the eggs, and later additional numbers were secured from a captive female. On April 25th of this year larvae were collected in the same terri- tory. This made possible the following somewhat incomplete life history. Egg. Echinoid, the body color mauve, covered with long green spicules. Micropyle, large, and deeply depressed. When fresh, the entire egg is a brilliant green. The female deposits her eggs singly, on the stems of oak. Undoubtedly these overwinter, and the young larvae emerge in the spring. The egg is illustrated on Plate PLATE 23 Egg of Strymon auretorum spadix highly magnified. Drawing by Comstock Mature larva. Length, extended, 16 mm. Slug shaped. The color varies from an apple green to pale orange. The green form may be descril)ed as follows: Body, ajjple green, covered with soiled white punctae from which arise short orange-chestnut hairs. The infra-stigmatal fold is soiled white, and in some examjiles its lower edge is laved with pale magenta. 79.
