AFRICAN LEPIDOPTERA. 327 



to the outer margin, gradually passing toward the anal angle into a 

 continuous zigzag line. This series of sagittate spots and lines are 

 followed on both primaries and secondaries by a submarginal line of 

 black, acutely angulated at the middle of each intra-neural space, 

 and this is succeeded on both wings by a marginal line also of black. 

 Between these two lines the ground color appears as a series of ful- 

 vous lunules. Near the apex of the secondaries, in the region cov- 

 ered in the male by the oval patch of dark leaden-hued, hair-like 

 scales, characteristic of the genus, are three heavy, oval, black spots, 

 of which the one in the middle is the lai-gest, and the first is fused 

 at the costal margin with the row of sagittate spots already described. 

 Two similar, but smaller spots, are found, one near the anal angle 

 and the other in the preceding intra-neural space. Fringe dark 

 brown. The under surface is much lighter than the upper, and alto- 

 gether lacking the purplish iridescence of the males. The markings 

 are as above, but very faint, excej^t in the case of the last of the band 

 of sagittate spots on the primaries, w'hich is heavy and black, and 

 the oval spots of the secondaries, which reappear on the under sur- 

 face as black ocelli, pupilled with white and surrounded by an ochra- 

 ceous ring. On their inner margin these ocelli are bounded by silvery 

 spots resembling those found in the genus Argyimis. One female ; 

 expanse 2] inches.

Dimorphic Female. — The dark fulvous of the basal area of the 

 upper surface of the wings of the typical female is replaced in this 

 form by dark fuscous, having an olivaceous tint, and shading into 

 black near the middle of the wings. The light fulvous of the outer 

 half of the Avings of the typical female is replaced by white, having 

 a lilacine lustre. The spots and lines are as in the typical form, but 

 broader and running together. The apices of both anterior and pos- 

 terior wings are also more or less clouded with fuscous, somewhat 

 obscuring the markings. The under surface is lilacine gray and 

 white, with the markings as in the typical form, but more distinct. 

 Head, thorax and abdomen concolorous. Four females; exp. 2> in.
