Show 86 DR. W. J. HOLLAND ON THE AFRICAN [Jan. 14, This division of the genus contains C. benga and possibly others. The fourth group is composed of species in which both secondaries and primaries are without sexual brands or marks of a conspicuous and easily discernible character, the brands and patches of raised scales being revealed in some of the forms only after bleaching and microscopic examination, and then as merely obsolescent. Neuration of Cwnides dacela, Hew. f. In the species of all these four groups the antenna?, the palpi, the neuration, and the outline of the wings are the same.

As to the identification of the male of this species with the insect described by Ploetz as Hesperia nydia, there is not a shadow of doubt m my mind. The insect described by Ploetz as Plastinqia podora was contained in the Berlin Museum. The insect labelled as such was examined for m e both by Dr. Karsch and Dr. Scudder and is represented 111 the plates accompanying this aiticle, bein^ reproduced after a careful drawing by Von Prillwitz. It is unmis°- lakably the female of C. dacela. Unfortunately, however the description given by Ploetz of his P. podora does not tally with the |
