i82 P. E. S. WHALLEY 



circular white marks. Veins R i and R b with common stalk. 2A off short stem of \A +2.4. 

 Underside similar to upperside, paler. Hind wing with Sc + R t free from Rs. 



Genitalia q* (PI- 47. fig. 268). Uncus simple. Gnathus with very small projection near 

 centre. Basal process on valve lightly sclerotized. Aedeagus with few spines on vesica. 



$. Wing, 17 mm. (Head missing from only female specimen.) Colour and pattern as in 

 male. Fore wing, i? 4 and i? 5 very shortly stalked. i.4 and 2A free at base, join for short 

 distance near margin. 



Genitalia ? (PI. 68, figs 443, 444). Anal papillae short, neck of bursa lightly sclerotized near 

 ostium. No signum in bursa. 



Discussion. This species is easily recognized by its pattern of circular white 

 marks, with much larger pattern than in C. tyrannica Whalley. The bifid tarsal 

 claws found in C. parobifera separate this species from C. orbiferalis. Both orbiferalis 

 and parobifera lack a prominent projection at the centre of the gnathus which is 

 found in C. tyrannica (see also under orbiferalis).

Cecidothyris tyrannica sp. n. 



This species can be separated from C. parobifera, which it most closely resembles, 

 by the colour and size of the maculations of the fore and hind wing. These macula- 

 tions are large and white in parobifera but small and yellowish brown in tyrannica. 

 The underside of tyrannica has dark brown median patches and usually three 

 subapical dark brown spots, all of which are lacking in parobifera which is a much 

 paler coloured species. In the male genitalia, the gnathus of tyrannica has a promi- 

 nent median process which is absent in parobifera. C. tyrannica is distributed 

 through East, Central and West Africa, with local differences in populations. 

 Specimens from the south Sudan are paler in the fore wing than those from the 

 Central African Republic and may be subspecifically distinct, but this decision 

 needs longer series. The most distinct difference in a local population is found in 

 East Africa where specimens have a lighter ground colour (still not as white as 

 parobifera) , and a more grey-brown general colour. The maculations on the East 

 African specimens are more distinct than in the other specimens.
