Distribution (Map 5). With the exception of one Nigerian specimen the species 

 is known only from Cameroun. The Nigerian male probably represents a new 

 subspecies, but further material is needed before this can be verified. 



Material examined. Type. Holotype^, Cameroun, Bitje, Ja River, 2,000 ft., 

 x. (Bates) ; Drepanidae genitalia slide No. 1178 ; in the British Museum (Natural 

 History).

Diagnosis. o\ $. This species is probably most closely related to inangulata from which it 

 can be separated by the angulate outer margin of the hind wing (Plate 9, fig. 305), the more 

 strongly arcuate outer margin and more strongly produced apex of the fore wing, by small but 

 easily recognizable differences in the male genitalia (eighth abdominal sternum, saccus, uncus, 

 gnathus, valves, vincular processes, base of aedeagus), and by the differently shaped female 

 genitalia (Text-figs, o* 1 72-1 74, $ 1 75) . The oblique postmedial fascia on the upper surface of the 

 fore wing is poorly defined in all the specimens examined, whereas about half of the available 

 specimens of inangulata have a strongly marked fasciae. The greater size, the absence of dark 

 costal markings in the costal area, and the genitalia distinguish smithi from excentrica, pianola 

 and subviridis. 



Measurements. A.P.R. : q*. 6 ; $. 4. Wing : q\ 22-5, 21-5-23-0 mm. (6) ; $. 24-0, 

 23-0-25-0 mm. (7). 



Discussion. The individual variation in the coloration of the upper surface is 

 similar to that found in inangulata. Two of the most interesting colour-forms are a 

 reddish brown male from Sankuru (Congo) and a slightly reddish, dark grey female 

 from Uele (Congo). 



Distribution (Map 5). Known from the Congo and Uganda. The single 

 specimen listed below from Uganda doubtless represents a new subspecies, but 

 further material is needed before it can be satisfactorily characterized and described.
