1890.] BUTTERFLIES FROM CENTRAL AFRICA. 465 



Underside. On the anterior wings the black bar at the end of the 

 cell is broader than on the upperside, little attenuated in the middle, 

 the lower part being developed into a large round spot. Posterior 

 wings with very broad black veins, connected on the margin by rather 

 broad black lines ; the spots in the submarginal row are seven in 

 number, larger and more 'quadrate than on the upperside, and touch 

 the black veins on either side at the opposite angles of each spot. 



Female. — Upperside. Wings greyish brown, the inner two thirds 

 shading into greyish white tinged with pale yellow ; on anterior 

 wings is a greyish-brown broad oblique bar, and on posterior wings 

 a distinct greyish-brown spot, each situate at the end of the cell. 



Urulerside. Anterior wings as above, with pale yellow streaks at 

 the apex between the subcostal and discoidal nervules, and indistinct 

 greyish-white patches between the median nervules and submedian 

 nervure near the outer margin. Posterior wings dusky white in the 

 middle, shading into pale dusky yellow at the base and outer margin, 

 where beyond the submarginal row of spots it is divided by the 

 broadly greyish-black nervules into rather brighter yellow lunides ; 

 the submarginal row of spots is indistinct and confluent with the 

 greyish-black nervules, and there is a distinct spot at the end of the 

 cell. 



Expanse of wings, male 21, female 1| inches.

Male. — Upperside. Both wings vitreous, with dusky brown veins ; 

 anterior wings with costal margin, apex, outer margin, and veins dusted 

 with greyish-brown scales, basal third densely dusted with bright 

 rufous scales, black at the base, a cluster of black confluent spots at 

 the upperside of the cell about its middle. Posterior wings with 

 the inner two thirds bright rufous, paler on the inner margin above 

 the anal angle ; the rufous space does not extend to the costal margin 

 or beyond two thirds of the central area, except towards the anal 

 angle, where it approaches nearer to the outer margin ; at the base is 

 a cluster and beyond the cell a row of seven black spots, the fourth 

 being out of line and nearer the outer margin ; between the basal 

 cluster and this row are two spots, one above the subcostal nervure, 

 the other on the inner margin.
