FIGURE 13. The Little Sulphur {Eurema lisa Bdv. & Lee.) synonym euterpe Men. has been listed for California by one of the early collectors, but later work over a period of many years has failed to substantiate the record. It is comparatively common in Southern Arizona, and there seems to be no reason why it should not become established in this state, in view of favorable climatic conditions and an abun- dance of foodplant. The larvae feed on Cassia and clover. Early stages. These were figured by Boisduval, but a careful recording of each stage in the metamorphosis remains to be done. Illustrated. Plate 16. $ fig. 11; $ fig. 13; $ underside, fig. 12. The Delia Sulphur (Eurema demoditas Hbn.) synonym delta Cram, is another species recorded for the state in the early days, and of which no confirmation has since been made. It is normally an in- habitant of the Gulf states. The early stages are probably similar to those of lisa. Illustrated. Plate 16. $ fig. 14; $ underside, fig. 16. Few illustrations of the early stages of California butterflies are available to nature students. This phase of the subject offers a fas- cinating field of research for the western lepidopterist. The com- plete metamorphoses of a large number of native species is entirely unknown, in spite of the ready availability of material for study. Col- lectors are urged to gather the eggs and caterpillars of every species that it is possible for them to secure, and to record their findings. The author will gladly cooperate in this work. A number of drawings of butterfly eggs, caterpillars and chry- salids are published in this issue of the Bulletin, which will consti- tute the first of a series of such illustrations dealing with the known life histories of our native Please note that these images are
