two-thirds of first tarsal segment ; pulvilliis and paronycliium present, the latter 

 without ventral lobe. SO" and R' of hindwing on a rather long stalk. 



(?. ("lasper with patch of friction-scales ; no corresponding scales on inner 

 side of the eighth tergite. Spnrs longer tlian in ? . 



?. Antenna somewhat grooved laterally, with distinctly prolonged seriate 

 ciliae. 



Early stages not known. 



Hal), Africa. 



Two species. 



Distinguishable from Meyanofon by the shorter hook of the antenna, the 

 penultimate segment of which is shorter than high, the much shorter tongue, 

 the longer and narrower second segment of the i:ialpus, the proportionally longer 

 first protarsal segment, and the absence of the ventral flaps of the paronychia ; 

 from Leucomonia by the absence of long claw-like spines from the first protarsal 

 segment, the much longer tarsi and shorter tongue. 



Key to the species :

(??. Both sexes have a i)rominent spine (not thorn or claw) at the end of 

 the foretibia exteriorly, which is wanting in nataleiisis. First segment of hind- 

 tarsus about H times as long as 2 to 5 together. The upperside of the forewing 

 has nearly the aspect of that of pale specimens of Protoparce rustica ; the white 

 stigma is conspicnons ; there are no longitudinal black streaks between R^ and 

 M- ; antemedian area white, especially behind ; a large median costal area centred 

 by the stigma more or less olive or yellowish olive, this colour spreading distad 

 to margin ; three dentate discal lines, the interspace between the second and third 

 more or less white. 



c?. Long apical spur of hiudtibia almost equal in length to the first tarsal 

 segment. Tenth tergite not divided, dilated just before the end, which curves 

 ventrad and is pointed, widened part convex above, feebly cariuate, the carina 

 extending to the tip, underside prismatically carinate ; sternite nearly as long as 

 the tergite in a side-view, narrowing to end, which is sinuate. Clasper almost 

 of equal width from middle to end, apex rounded ; there is a long j)atch of narrow, 

 non-dentate, pointed (lanceolate) friction-scales, all short except the middle ones, 

 which are strongly prolonged and stand upright, forming a long and high crest, 

 which is very conspicuous ; no friction-scales on the innerside of tergite s : the 

 inner surface of the clasper is deeply concave ventrally in middle. In this cavity
