Tuts superb butterfly has the upper surface of its 
wings of a brilliant green, shaded of a paler colour 
towards the upper and lower dises of the superior 
wings ; all the wings have a black margin entirely 
surrounding them ; in the centre of the upper wings 
are two large longitudinal black patches, which 
occupy nearly the half of them; on each of the 
lower wings are four large circular black spots, and 
a golden yellow square spot close to the edge of the 
upper surface ; the head, and upper part of the back,
