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 antenne 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.

Ceratrichia semilutea, Mabille, C. R. Soc. Ent. Belg. 1891, p. lxv. 
Hab. Tropical West Africa. 
This species appears to be very common on the Ogové. 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 speci- 
men 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been designated as the type of an unpublished species by Mons.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 CO. 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 ex- 
amples of this form are sure to be found.
