Male. — Head black, palpi golden yellow; collar golden yellow in front. Antennae deep 

 black, slightly ferruginous beneath. Thorax deep black, with a golden yellow line on each side and 

 a transverse mark of the same color posteriorly. Underside of thorax golden yellow. Abdomen 

 black, second and last four segments with a broad golden band. Anal tuft black, yellow beneath. 

 Legs golden yellow, with a black band on the tibiae. Fore wings transparent, borders, discal mark 

 and veins brown black, with the opaque portion between the veins more or less coppery red. 

 Basal transparent area elongate triangular, outer area small, rounded ; underside with the red parts 

 predominating and brighter than above. Hind wings transparent, outer border narrow, brown with 

 a rather broad coppery red line, underside like the upper, but the costa is coppery red. 



Fejnale. — Like the male, but the fore wings are usually more opaque and redder, or are yellow 

 between the veins. The last three segments are broadly banded with yellow, instead of the last 

 four as in the male. Anal tuft golden yellow, with a little black on top in the middle. 



Expanse : Male, 22-25 mm - » female, 25-27 mm.

Nothing is known about the earlier stages of this species. It is somewhat 

 variable in the coloration of the fore wings. These vary from golden yellow to 

 orange red or golden bronze.
