Genitalia $ (PI. 62, fig. 383). Anal papillae short. Bursa with two prominent, inward 

 projecting, thorn-like spines. 



Discussion. This species has rather long, narrow fore wings each with a pointed 

 apex. It is related to H. distrindus from which it can be separated by the rather 

 grey fascia of the wings and the shape of the genitalia. The antennae show sexual 

 dimorphism as in H. distrindus. The genitalia of quaesitus are similar to curvifluus 

 but the spines in the female of curvifluus are larger and there are other genitalia 

 differences. The grey fascia on the wings and the wing-shape make this species 

 easily recognized.

Hypolamprus gangaba sp. n. 



(PI. 15, fig. 78; PI. 39, figs 217, 218; PI. 62, figs 384, 385) 

 [Rhodoneura bastialis auct., nee Walker, 1859.] 



o*. Wing, 8-5-Q-5 mm. Vertex orange-brown, irrorate with white. Frons not projecting 

 between eyes. Antennae minutely ciliate. Labial palps with third segment more than 1/2 

 length of second, upturned reaching vertex. Patagia light brown, rest of thorax paler. Hind 

 tibia with inner spur of each pair much longer than outer spur (2^-3 X ) . Fore wing, pattern 

 as in PI. 15, fig. 78, white with brown and black transverse lines. Apex of wing white with 

 two or three black spots. Costal margin brown. Underside, pattern as upperside but darker, 

 apical white area more conspicuous. Hind wing, as fore wing, no white at apex. Veins Sc + R t 

 and Rs approach closely but do not fuse. 



Genitalia q* (PI. 39, figs 217, 218). Uncus simple, gnathus a weakly sclerotized loop. Valve 

 simple, median basal process sclerotized, bifid, median arm with small spines. Juxta highly 

 modified with spiny apical process, narrow, sclerotized lateral arms and two toothed projections 

 from base. Aedeagus with spiny vesica. 



$. Wing, 7*5-12 mm. Colour and pattern as male. 



Genitalia $ (PI. 62, figs 384, 385). Anal papillae short. Ostium with two sclerotized lateral 

 lobes, covered with small spines. First part of duct sclerotized, with small spines, remainder 

 of duct convolute. Two sclerotized thorn-like signa in bursa. 



Discussion. Some variation in colour exists, with a few specimens being darker 

 brown than others. There is also some variation in pattern over the range which 

 may be of subspecific nature but on material available this is not clear. Considerable 

 variation occurs in size of specimens in the series examined, the females from West 

 Africa tending to be smaller than females from South Africa. H. gangaba is very 

 similar externally to R. bastialis Walker. It can be distinguished from this species 

 by the shape of the signum in the female and the shape of the juxta in the male.
