with yellow ; whilst the apical area of the primaries and the whole of 

 the secondaries on this surface are bright golden buff approaching a 

 mustard-yellow ; the external border on the upper surface of the 

 primaries is browner, and does not run so far along the costa, is 

 narrower throughout, and the inner border is narrower, and fades away 

 into greyish flesh-colour at the base in the Angola species. I therefore 

 have not the slightest hesitation in considering these two to be 

 abundantly distinct, though allied species. 



As it appears to me to be always for the good of science to correct 

 errors as soon as possible after their publication, as I have monographed 

 the genus TeracoJus, and, lastly, as the British Museum possesses the 

 finest and most complete collection in the world of these beautiful 

 butterflies, I think it my duty to add here a few notes upon the 

 species figured and remarked upon by Dr. Staudinger in his work now 

 publishing. I have no desire to dispute his right to place his species 

 in three, or if he prefers it in more genera, but simply to point out a 

 few inaccuracies arising from the effort to work out a difilcult group 

 with insufiicient material. 



On plate 23 of his work, Dr. Staudinger figures the following : — 



1. Idmais JSris, Klug, (J , correctly identified. 



2. I. Vesta, Eeiche, (? . Our examples of T. Vesta are males, and correspond 

 with the original figure ; the species figured by Staudinger is perfectly distinct, and 

 is my Teracohis argillacens ; it is considerably smaller than T. Vesta, the base of 

 the wings above is not black as in that species, the apical area of primaries and entire 

 surface of secondaries below are piuky-ochraceous, instead of pale sulphur-yellow, and 

 the central band of the latter wings is the only dark one, though Staudinger's figure 

 fails to show this difference. 



3. /. Pleione, Klug, $ , correctly identified. 



4. J. costalis, Stgr., a new species allied to vestalis. 



5. I. venosa, Stgr., J . This appears to me to be allied to Belenois Charina, but 

 to be figured from an example in which the antennae are broken short off : if this is 

 so, we have a nearly allied species from the Nyanza ; ours is, without question, 

 closely related to B. Charina. 



6. Teracolus suhfasciatus. Swains., $ , correctly named. 



7. T. protomedia, Klug, <? . The insect figured is a female ; we have a series of 

 both sexes. 



8. 9. Callosune Johina, Butl., (? , ? , correctly named. 



10, 11. C. Jalone, Butl., 3* , ? , apparently rightly named, but not well figured. 



12. C Amina, Hew., S , correctly named. 



13, 14. C. cinerascens, Butl., <? , ? , correctly named. 

 15, 16. C Aiixo, Lucas, (J , ? , correctly named. 



17. C. Achine, Cram., ^ . The species figured is the T. Omphale of G-odart. 



18. C. HaevernicJiii, Stgr., ^ . This is the male of my T. hannonides.
