it is inseminated more frequently. This hypothesis can be tested by obtaining data on the relative frequency of insemination of mimic females in populations where the proportion of the mimics is small.
While the mechanism which maintains the dimorphism in P. glaucus is not yet clearly understood, the evidence collected to date shows that regional differences exist in the frequency with which the two female morphs are inseminated.

PSEUDOPHILOTES BEURET, 1958
In a recent article of mine about Glaucopsychie piasus I called attention to the fact that Philotes sonorensis, the type species of Scudder's genus, is generically different from the rest of the genus found in North America. This requires a different name for enoptes and its allies. Such a name has been proposed. It is Pseudophilotes Beuret, 1958, with European baton as its type species. Baton is cogeneric with enoptes, et al.
The probable reasons for this generic name being overlooked by American taxono-mists are two: the Zoological Record citation made no mention of nearctic members in Pseudophilotes; the paper in which the name was proposed is in a journal rarely seen in North America. The full citation for the description of Pseudophilotes is: Beuret, H., 1958, "Zur systematischen Stellung einiger wenig bekannter Glaucopsychidi (Lep., Lycaenidae)" Mitt. ent. Ges. Basel (N.F.) 8: 61-79, 1 pi., 12 figs.; 8: 81-100, 13 pis. The original description begins on page 100.
I wish to thank Dr. Lionel G. Higgins for calling this publication to my attention.
