grey. Tongue extremely long and flexible, black and shining. 

 Thorax remarkably broad and robust, dark grey. Abdomen 

 broad, short and rounded, grey above, shading into blackish 

 behind, blotched at the sides with black and pale yellow, and 

 having on the sides of the last four segments large spreading 

 tufts of black scales edged with white, those upon the final 

 segment extremely broad, squared, and massed together. 



Fore wings stout and strong, rather short, bluntly pointed, 

 having the costa straight to near the apex ; hind margin 

 slightly rounded and very oblique ; dorsal margin short, 

 slightly hollowed. Hind wings short, with the apex and 

 hind margin rounded, and the slightest possible hollowing 

 out before the anal angle. Fore wings dark grey, with a 

 distinct, black, slender, sinuous, transverse stripe before the 

 middle, and a less distinct, rather elbowed, similar stripe 

 beyond the middle, each having on the inner side a faint 

 parallel duplicate line ; another, very slender, faintly dark 

 line crosses the wing at some distance outside the second 

 black stripe; and immediately following, with its margin 

 exactly parallel, is a darker grey shade which occupies the 

 entire hind margin. At the end of the discal cell is a round 

 black dot ; cilia dark grey. Hind wings pale tawny, darker 

 towards the hind margin, which is edged and shaded with 

 blackish brown; base blackish, shading into the tawny 

 colour ; cilia pale brown. 



Under side of fore wings golden brown ; of hind wings, pale 

 golden brown, shading into yellow at the anal angle. Face, 

 legs, and thorax beneath, whitish ; abdomen yellowish- white 

 mixed with blackish, and having the lateral tufts of long 

 scales black and white. 



Very little subject to variation, but occasionally the hind 

 wings have the tawny colour replaced by dark brown, faintly 

 streaked with golden brown, especially towards the anal 

 angle.
