Palpi and legs pale yellow. Antennae black, before the tips yellowish-white. Forewing orange, costal margin 
and all the veins black, cross-vein broad black. Behind it hyaline dots are marked only in one of the two

the forewing is more intensely yellow, only in the distal area with black veins and margin. Hindwing with an 
orange cross-vein and margins, fringe above and beneath blackish-brown. C 20 mm. Sierra Leone. Type in 
the Berlin Museum. 
Ch. brillians Beutenm. (77 c). Body with orange-red and black stripes. Forewing orange-red. Wedge- brillians. 
area punctiform, the distal hyaline area only at the ends marked by one hyaline dot each. The surroundings

margin narrow blackish-brown. 13—16 mm. Spanish Guinea, Ogove.
