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 Cenides dacela, Hew. 2. 
In the species of all these four groups the antenne, the palpi, 
the neuration, and the outline of the wings are the same. They 
are differentiated into groups by the sexual markings of the male 
sex, so far as my studies have informed me. Most of the species 
have been hitherto referred by writers to the genus Proteides, to 
which they manifestly do not belong.

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 in my mind. The insect described by Ploetz as Plastingia 
podora was contained in the Berlin Museum. The insect labelled 
as such was examined for me both by Dr. Karsch and Dr. Scudder, 
and is represented in the plates accompanying this article, being 
reproduced after a careful drawing by Von Prillwitz. Itis unmis- 
takably the female of C. dacela. Unfortunately, however, the 
description given by Ploetz of his P. podora does not tally with the
