Tiiiigiic very short. Paljins smooth-scak'd, the scales erect ; joint open. 

 Antenna of d ratlier strongly grooved, side-line nndnlate iu a dorsal view, ventral 

 line of each segment (in side-view) straight, the apical sensory cone prominent, the 

 ventral parts of the segments not touching one another ; in ? ronnded-triangnlar 

 in transsection, very feehly grooved, bnt the segments somewhat constricted at the 

 joints, the basal and dorsal fasciculated ciliae somewhat j)rolonged, the longest of 

 about the same length as the segment, the fascicles not close together. Spurs spinose, 

 the long terminal one of the hindtibia about two-fifths the length of the first tarsal 

 segment ; hindtibia as long as tarsal segments 1 and 2 together. Body woolly, 

 scarcely with any short broad scales ; abdominal tergites with long weak sjnnes 

 all over, the spines dense at the edges. Distal margin of wings entire, of forewing 

 straight or convex, sexes different, <J with apex of forewing very little or not 

 produced, ? with the apex almost hooked, hinder margin straight or nearly straight; 

 hindwing very strongly rounded, more so in d than in ? ; D- very oblique, more 

 than twice the length of D'. No organ of friction on the clasper and the eighth 

 tergite. 



Both sexes vary in the ground-colour and in the distinctness of the markings ; 

 sometimes there are scarcely any markings at all. The stigma of the forewing is 

 often very consj)icnous ; sometimes it is represented by a ring, and is also often 

 wanting. Some individuals have a brown cloud along the abdominal margin of 

 the hindwing, this cloud corresponding to the black patch found in niyriplaga. 



S. Eighth tergite slightly but distinctly sinuate in the middle (best visible 

 from the underside after the clasjiers have been taken out). Tentli tergite very 

 short, triangular, gradually narrowing to the blunt ai)ex, longitudinally impressed ; 

 the sternite rather broad, curved dorsad, apically pointed or rounded, sides slightly 

 angled and bent ventrad, hence the under surface of the plate concave. Clasper 

 (PI. XXXIV. f. 3) very much reduced in size, covered with very long narrow scales; 

 it is apically narrowed to a ladle-like process, from the cavity of which projects 

 a sharp hook of the harpe (pvd); the harpe occupies the whole cavity of the 

 clasper, and is dorsally divided into two folds (m and n). Penis-sheath without 

 armature, very short, ajiically flattened, j)rolonged into a triangular blade. 



? . Eighth abdominal tergite membranaceous, feebly incrassate at the edge. 

 Vaginal plate (PI. XVII. f. 13) with a transverse smooth fold which is widened 

 mesially and bears here a more or less triangular lobe ; postvaginal plate mem- 

 branaceous, scaled, excejiting middle. 

 Early stages not known. 



J/ab. ('ontinental Africa, from Natal to British East Africa and Senegambia, 

 probably all over the Aethiopiau region exclusive of Madagascar and the neighbouring 

 islands. 



Two subspecies, which are structurally alike.

(J. Distal margin of forewing convex. The discal line of the underside of 

 the hindwing as a rule close to cell, straight, occasionally some mm. distant 

 from cell and curved. Distinctness of the lines very variable. The subraargioal 

 vein-dots of the hindwing sometimes transverse, occasionally situated in an obscure 

 line.
