diffused discal spot on the medial line ; the postmedial line waved, the 

 subterminal straighter than on the forewing. 



Underside of both wings pale brownish-grey, with discal spot, short 

 anterior medial line (on hind wing continued to the discal spot), post- 

 medial line, diffused subterminal shade and margin and fringe as above. 



Congo Free State: Lufira Valley, "Dec. & Nov." (? Nov. & Dec), 

 1918. (T. A. Barns.) One S . 



This species seems to agree with Hampson's genus Argyrolopha 

 except in the absence of the large crests on the second and third 

 abdominal segments. As the abdomen of the Lufira Valley specimen is, 

 unfortunately, denuded, it is impossible to say whether or not the crests 

 should be present.

 double, excurved from costa to SC, obsolescent in cell, incurved from 

 M to SM 2 ; antemedial line oblique from costa at about one-fifth, 

 slightly angled in behind SC, thence broadly excurved to hind margin 

 at about one-fifth ; some dark shading behind M between the ante- 

 medial and subbasal lines ; orbicular a black dot ; reniform indicated 

 by a white dot ; two outwardly oblique medial streaks from near 

 middle of costa ; postmedial line from costa at about two-thirds, 

 strongly bent outward to SC 5 , irregularly dentate and inwardly oblique

 line pale, distally dark-edged, strongly angled outward behind SC 4 

 and slightly behind SC 5 , nearly straight to M 2 , behind which it is
