After a very careful microscopical study of the anatomical details of the structure of the three preceding species, I can find nothing of generic value to lead me to separate them from the species included in the genus Pardaleodes, though in general appearance they present widely different features. The total absence of translucent spots on the primaries, the broader and more rounded character of the wings, and the general style of the markings at first sight appear to reveal such a difference as to have led me for some time to have been inclined to refer these species to the genus Koruthaialos, Wats., but the palpi, the neuration, and the antenna? are so exactly in agreement with those of the genus Pardaleodes, that I am constrained, in spite of the facies, to place them in the latter genus.

Tropical West Africa. This species appears to be very common on the Ogove. The female has the primaries profusely spotted in some specimens, and the secondaries more or less suffused with brown, almost obscuring the broad yellow middle area. Ceratrichia semilutea, Mab., the type of which is before me as I write, is a slightly dwarfed specimen of the male. Another male, in the Staudinger collection, has been designated as the type of an unpublished species by Mons. Mabille, to which he gives the MS. name C. punctata. It is a male with the primaries more spotted than is quite usual, though in a long series of specimens, such as I possess, numerous examples of this form are sure to be found. 273. C. FLAVA, Hew.
