2. L. Antiacis, Boisd.
May. Different localities.
3. L. Xerxes, Boisd.
May. Lone Mountain, near San Francisco; rather rare.
There exists no European analogue to this very peculiar type.
4. L. Piasus, Boisd.
Very common throughout middle California. It replaces the Atlantic L. Pseudargiolus, and L. neglecta, Edw., as well as the European L. Argiolus; and belongs to one of the most cosmopolitan types of the genus. The caterpillar feeds on the flowers of the Pavia, unlike its European representative, which feeds on the leaves of Rhamnus frangula.
5. L. Pheres, Boisd.
May and June. Lone Mountain, near San Francisco. I do not know of any other locality.
