anastomosing. Hind wing, pale sandy brown, reticulations lightly marked. Underside pale 

 yellow. 



Genitalia q* (PI. 26, fig. 140). Median process on valve pointed. Median juxta arms broad. 

 Lateral process on aedeagus pointed. 



$. Unknown. 



Discussion. This is one of the most distinctively coloured of the African 

 Chrysotypids. The pattern is greatly reduced and the very pale sandy colour is 

 quite different from the brown of other Chrysotypids. Morphologically this species 

 is close to C. reticulatus. At present C. subflavus is known from only one locality 

 but was collected over several years and at different times of year.

Chrysotypus luteofuscus sp. n. 



(PI. 3, fig. 6; PI. 27, fig. 141) 



o*. Wing, 17-19 mm. Vertex white, irrorate with brown. Base of antennae white, frons 

 with white scales laterally, clypeus not swollen. Antennae strongly bipectinate. Labial 

 palps with third segment 1/3 length of second, upturned, not reaching vertex. Proboscis small. 

 Patagium golden brown, irrorate with white. White scales distally on each leg segment. Hind 

 tibia with scale crest on posterior margin and with two pairs of spurs. Fore wing, pattern as 

 in PI. 3, fig. 6, translucent yellow-brown, with darker brown fascia. Basal area of fore wing 

 brown, costal margin with white scales along length. Vein i? 4 and i? 6 anastomosing. Hind 

 wing, colour and pattern as fore wing, Sc+R 1 and Rs free. 



Genitalia <$ (PI. 27, fig. 141). Juxta lobe 1/2-2/3 width of valve. Lateral process of 

 aedeagus slightly bifurcate. 



9. Unknown. 



Discussion. This species can be separated from the other African Chrysotypids 

 by the wing pattern. The amount of reticulation of wing pattern is less than in most 

 other species in the genus. The slight bifurcation of the lateral process of the 

 aedeagus seems characteristic. This species shows a further specialization in pattern 

 as shown by the series splendidus — reticulatus — circumfuscus where the pattern tends 

 to concentrate and the amount of reticulation to be reduced.
