168 P. E. S. WHALLEY 



as in PI. 21, fig. 112, dark brown with lighter rounded areas. Costal margin dark brown. 

 Underside similar, paler, dark brown restricted to cell and anal area. Hind wing, lighter 

 coloured than fore wing, less dark brown, small rounded areas present, underside with a few 

 dark spots. Veins Sc-\-R 1 and Rs free. 



Genitalia q* (PI. 45, fig. 256) . Median basal process of valve well sclerotized. Manica spined. 



9. Unknown. 



Discussion. The circular patches in the fore wing pattern are typical of the 

 genus Opula but this species can be separated from the others in the genus by the 

 pale coloured hind wings. No information on the biology of this species is available 

 but from the locality data this species is forest-dwelling.

Opula hebes sp. n. 

 (PL 21, fig. 113; PI. 45, fig. 257) 



o*. Wing, 23-5-26 mm. Vertex brown. Frons rounded, protruding in front of eyes. 

 Antennae minutely ciliate. Labial palps with third segment 1/3 length of second, upturned, 

 just reaching vertex. Thorax brown. Hind tibia with scale crest, outer spur of distal pair 

 2/3 length of inner spur, longest distal spur less than 1/2 length of 1st hind tarsal segment. 

 Tarsi mostly without spines but one pair of spines on last tarsal segment, in front of claw. 

 Fore wing, pattern as in PI. 21, fig. 113, brown with darker brown reticulations. Underside 

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



Genitalia q* (PI. 45, fig. 257). Uncus slightly thickened dorso-ventrally. Gnathus with 

 prominent median, spiny, process. Juxta with two simple lateral lobes. Basal process on 

 valve small. Valve simple. Aedeagus with vesica covered with minute spines. 



$. Unknown. 



Discussion. This species is externally similar to 0. impletalis but is much larger 

 and has differences in the genitalia. As with 0. monsterosa, this species is super- 

 ficially similar to species of the genus Chrysotypus but they are morphologically quite 

 distinct. 0. hebes and 0. monsterosa both occur together in the same locality in 

 Uganda where a single specimen of each was collected in the same month. These two 

 species can be separated from one another by the pattern and the genitalia. The 

 female of 0. hebes is unknown but it is interesting to speculate on the possible shape 

 of the signum in the bursa with reference to the known species. It may be a trans- 

 verse signum as in impletalis, which is more typical of the genus, or it may be a 

 longitudinal signum as in monsterosa. The males of hebes and monsterosa are similar 

 to one another and less like impletalis which suggests that the signum in the female 

 of hebes should be longitudinal.
