Head black. Antennae white at apices, in (J rather deeply 

 laminate. Thorax black. Abdomen in $ with seven, in 9 with 

 six orange or reddish-orange rings; tuft in $ orange. Fore-tibise 

 with a posterior tuft more or less ochreous. Forewings with spots 

 pale ochreous, semi-hyaline; very rarely a small supra-apical or 

 intermediate dot. Hindwings with spots separate. 



Var. a. Abdominal tuft in ^ black at sides. At one time I 

 considered this a distinct species, but after examination of large 

 series from different localities I do not think this can be main- 

 tained. 



Var. h. Basal spots of wings reddish-tinged. 



Var. c. Upper segment of discal spot of hindwing minute or 

 absent. 



Var. d. 9- Fore wing with basal and dorsal spots partly con- 

 fluent. A very rare individual abnormality. 



The spots are smaller in ^ than (^; in some males this differ- 

 ence is exaggerated. As a general rule the males are larger, but 

 they vary from 28 to 45 mm. Sir Geo. Hampson's synonymy of 

 this species needs revision.

 Australia.
