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 I 

 found half a dozen or more examples which seemed to corre- 

 spond in the possession of certain characters in both sexes, I 

 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 T. 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 T. 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 T. eione or 

 T. Emini. Typical T. antigone has no internal stripe. Of 

 the named forms, T. phlegetonia and T. minans are wet- 

 season phases, T. friga is intermediate, and the remainder 

 are variations of the dry-season form. 



47. Teracolus glycera. 



3 . Teracolus glycera, Butler, P. Z. S. 1876, p. 144. 



Exact locality unknown. Type B. M. 



It is possible that this may prove to be an aberrant inter- 

 mediate-season form of T. 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.
