THYRIDIDAE OF AFRICA AND ITS ISLANDS 183 



frons, second segment slightly longer than first. Thorax, tegulae, pale brown. Fore wing, 

 pattern as in PI. 2, S, brown with grey-white costal and basal areas. Anterior part of median 

 area also grey-white. Reticulate pattern prominent, ground colour pale yellow-brown. Vein 

 R A and i? 5 stalked (R 3 and i? 4 in some specimens). 1A and zA start separately, joining 1/3 

 from base. Underside, darker than upperside, median area dark brown, three or four subapical 

 dark brown spots in between veins. Hind wing, pattern and colour as fore wing. Sc+R 1 

 and Rs free. 



Genitalia <J (PI. 47, fig. 269). Uncus simple. Gnathus with central peg-like projection. 

 Juxta with two lateral lobes, each covered with short hairs. Aedeagus with minute spines on 

 manica. 



$. Unknown. 



Discussion. There are two different arrangements of the radial veins in the 

 fore wing in this subspecies. The three specimens from Ghana have R 4 and R 5 with 

 a common stalk. The Sudan and Central African Republic specimens have R 3 

 and i? 4 with a common stalk, but I can find no other differences between specimens 

 of these two series. This variation in stalking of the radial veins is also found in the 

 other subspecies. C. t. tyrannica can be separated from C. t. affinia by its yellow 

 ground colour and reddish brown, rather than dark brown, colour. The pattern of the 

 fore and hind wings of C. t. affinia consists of larger maculations which show more 

 clearly than C. t. affinia.

Cecidothyris tyrannica affinia ssp. n. 



(PI. 2, R;P1. 47, fig. 271) 



o". Wing, 15-18 mm. Structurally similar to the nominate subspecies. Distinguished by 

 the darker brown colour and white (not yellow-brown) ground colour. Maculations more 

 distinct than in the nominate subspecies (PI. 2, R). 



Genitalia <$ (PI. 47, fig. 271). Similar to nominate subspecies. Vesica of aedeagus slightly 

 less spinose. 



$. Unknown. 



Discussion. Specimens of this subspecies are much darker than the nominate 

 one. It seems to replace the nominate one in East Africa.
