broad yellow bands, the actual extent of the yellow area being very 

 variable. The outer row of spots in the fore wings is lost except in a 

 few local forms, in which the yellow area has been curtailed, and there 

 is room for a pale narrow subterminal line. 



Black, forewing with a broad yellow fascia along the middle of the 

 wing from base to beyond middle more or less indented along the 

 upper margin of the cell at the end and about the middle, a broad 

 transverse yellow fascia across the apex, and another from vein 4 

 to the middle of the inner margin, a narrow terminal yellow line. 



Hindwing with a broad yellow transverse band across the middle 

 of the wing and a narrower one beyond it. 



Underside much paler, the markings less distinctly indicated. The 

 ground colour, especially near base, thickly irrorated with pinkish-grey. 



Expanse.— 1" to If." (Plate C, fig. 13.) 



Larva. — Appears to occur in two forms, and has been described

A. Euthalia. 



Apatura naiS, Forst. — Bright reddish-orange. Forewing with a 

 large subquadrate black spot at the end of the cell with indications 

 of a reddish centre. A large black patch beyond and below it 

 from base of vein 4 to 2, obscurely defined on its inner margin. A 

 broad macular transverse band from the middle of the costa to vein 

 4 beyond middle, a subterminal blackish line sometimes joined by 

 suffusion along the veins to the broad black-brown margin. Cilia white, 

 broadly blackish on the veins. Hindwings with a black triangular 

 fascia on the costa before the middle, a macular band of spots beyond 

 middle and broad blackish margin. The extent of the black-brown 

 markings varies, and is much reduced in dry season forms. 



Underside pale pinkish-orange, suffused over the basal and apical 

 thirds of the forewing, and the whole of the hindwing with pinkish- 

 brown. Terminal and median spots in the cell prominent pinkish- 

 red with black margins. A pale chrome transverse band before apex 

 of forewing and a median irregularly shaped band of the same colour 

 on the hindwing. A subterminal row of brownish-black spots 

 across both wings, each spot with a pale suffusion beyond it. Two 

 reddish-pink dark outlined spots in the cell of the hindwing an A
