Ranges from Accra eastwards to the Albert Nyanza and 
thence southwards to Cape Colony. 
When I described the above forms as distinct we had no 
examples of the very distinct wet-season phases from the 
south, nor was I aware of the variability or the seasonal 
distinctions which occur in Teracolus; therefore when IL 
found half a dozen or more examples which seemed to corre- 
spond in the possession of certain characters in both sexes, [ 
naturally supposed that I had different species before me. 
The Godman and Salvin collection, which was tolerably rich 
in examples of this species, has enriched our series, adding 
eight typical examples of 7. phlegetonia (wet-season) from 
the Cape of Good Hope, also five examples of the variety 
T. minans=coniger from the Cape, as well as seven examples 
of the dry-season variety JZ. delphine. With our present 
series I am satisfied that the above synonyms represent one 
tolerably variable species. I cannot, however, believe that 
T. antigone, the wet-season form of which always has both 
the base and apex of the primaries bright lemon-yellow on 
the under surface, and which has a much narrower internal 
black stripe in all its forms, is identical with 7. ezone or 
T. Emint. ‘Typical 7. antigone has no internal stripe. Of 
the named forms, 7. phlegetonta and T. minans are wet- 
season phases, 7. friga is intermediate, and the remainder 
are variations of the dry-season form.

Exact locality unknown. ‘Type B. M. 
It is possible that this may prove to be an aberrant inter- 
mediate-season form of 7. antigone, for, although the inner 
margin of the orange apical patch is unbroken by the usual 
black marking, the primaries have the same yellow basal 
suffusion, and the other characters nearly correspond with 
those of that species.
