Genus CERATINIA Fabricius

Distinguished from other allied genera by the strongly lobed costal margin of the hind wings in the male.

There are fifty species of this genus known from the American tropics, but only one occurs within the limits of the United States, and only in the extreme southwestern portion of our territory.

(1) Ceratinia lycaste (Fabricius), [Plate III], Fig. 2, ♀ (Lycaste Butterfly).

This insect, which may easily be identified by the figure we give, is reported from southern California. The plate shows the variety, named negreta, which has a spot at the end of the cell of the hind wing instead of a black bar, as is the case in specimens from Panama. Expanse 2.1 to 2.25 inches. Wright does not include this species in his list of butterflies of the west coast.
