1920] Holland, Lepidoplem of the Congo 269 



near the base, the black border rapidly widening about the middle of the costa and 

 passing into the broad black outer margin, which covers the outer half of the wing, 

 leaving the inner white area as a large outwardly evenly rounded spot, marked by a few 

 dark rays upon the nervules near the base, and defined below by a fine black line 

 upon vein 1. The upper side of the hind wing is similar in coloration to the fore wing, 

 the broad black outer border beginning on the costa at a point about three-fourths 

 of its length fi"om the base, and extending to the anal angle, the white area projecting 

 into it beyond the cell, and giving it at this point a somewhat angulated appearance. 

 On the under side the wings are much as on the upper side. 



9 . The female is like the male but the antennae are not heavily pectinate but 

 filiform, the wings are relatively broader, and the black outer margins of both wings 

 are much reduced in width, and in some specimens on the hind wings are absent or 

 only represented by a few marginal spots beyond the cell, though the part of the 

 outer band at its beginning on the costa of the hind wing invariably persists. Expanse 

 0^,35 mm.; 9,40mm. 



I have a long series of this insect which has stood in my cabinet for 

 a quarter of a centmy awaiting description ; there are numerous males 

 and many females, taken at Benito and at Kangve in the valley of the 

 Ogove River. The presence of a 

 single specimen of the aberrant 

 form of the female, in which the 

 outer margin of the hind wing is 

 reduced to a few black spots, induces .
