4. A. polyphemus Fab. Figured in Nat. Lib. XXXVI. 



Antennae ferruginous ; body of the same color ; head cinereous. 

 Superiors falcate, especially in the male. Upper margin cinereous, 

 or dull ochre yellow. Base and outer edge russety. About half 

 from the centre to the tip they are sprinkled with dark brown. 

 Towards the base an irregular band of pale white and carmine. 

 An obsolete ferruginous band crosses the middle. Towards the 

 margin a band of pale purple and brownish, terminated at the tip 

 with a black spot interrupted by the nervurS, on a whitish ground 

 nearly surrounded with purple. Near the centre there is an ocel- 

 late, transparent spot, bordered with a double ring of yellow and 

 black, and a whitish semicircle towards the base. 



Inferiors, fulvo-cinereous ; posterior border russety ; a broad 

 band, half pale violet and half blackish, surmounts this border. 

 In the centre, a large black ocellate spot, with a yellow iris and a 

 transparent oval point in the middle. Above the transparent part 

 there is a blue dust that insensibly mingles with the black. 



On the under side the ground color is paler, but the bands are 

 more distinct. The outer border of the superiors is deep brown. 

 The base of the inferiors is brighter ferruginous, resting on a brown 

 band crossing both inferiors horizontally. The black part of the 

 ocellate spot on the upper side is not discernible, and instead of 

 the band there is a row of indistinct semicircular spots. Expands 

 nearly six inches. 



Larva, somewhat similar to that of A', luna, but it is destitute
