After a very careful microscopical stydy 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 Koruthaiulos, Wats., but the palpi, the neuration, and 

 the antennas are so exactly in agreement with those of the genus 

 Pardcdeodes, that I am constrained, in spite of the facies, to place 

 them in the latter genus.

Hab. 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 leas sufi'used 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 Staudiuger collection, has 

 been designated as the type of an unpublished species by Mons. 

 Mabille, to which he gives the MS. name O. 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.
