cj and ?. Wing, 11-11 mm (<J), 19-22-5 mm ($). Externally the dark brown pattern on the 

 median and basal areas of the fore and hind wing separates this subspecies from the nominate 

 one (PI. 2, O). The frons is usually much enlarged, projecting between the eyes. Veins i? s 

 and i? 4 fuse for part of their length in many specimens from West Africa and all intermediates 

 from R 3 and R t completely free occur. Considerable variation occurs in the intensity of the 

 colour and of the pattern, but from the specimens examined they appear to be equally variable 

 over the whole range. There is a tendency for the specimens from West Africa to have a much 

 darker terminal and subterminal area on the wing than the specimens from East Africa. 



Genitalia q* (PI. 46, fig. 265). 



The larvae of this subspecies, as with the nominate subspecies, produce galls on 

 the twigs of Terniinalia species but in this case a different species of Terminalia, 

 T. avicennoides (Ufaruna, 1968), see p. 19.
