Palpus with a very short, triangular tuft on under side of second segment; 

 third as long, slender. Fore wing with M t approximate to R 4+5 ; M 2 separate; hind 

 narrower than fore wing, with M 2 nearer Mj than M 3 ; apex produced.

 margin of fore wing, cream white; shoulders black, shading into cream white; 

 costa white; fringe cream white except at apex. 11 mm.

21. ARISTOTELIA Hiibner 



(Ergatis Heinemann, with Eucatoptus Walsingham ) 

 Palpi small, often quite rough. Fore wing broad, lanceolate (fig. 164). Mj 

 free; M, and M 3 occasionally stalked; the other veins free. Hind wing falcate, with 

 produced apex; cell large; R and Mj divergent but widely separate at base; M, 

 nearer Mj than M 3 ; M 3 widely separate from CUj. Hind wing narrower, sometimes 

 much narrower, than fore wing. Male sometimes with a costal hair-pencil on 

 hind wing, not disturbing the veins (Eucatoptus). 



The palpi in this group are strongly divergent, and the patterns described are 

 those of the inner face; the outer face is usually similar but with a little more 

 black.
