side and joins the central white fascia ; the apical portion is coloured 

 as in the fore-wings. The lunule is smaller and more curved than in 

 the fore- wings, but similarly coloured. 



The antennae are fulvous. The abdomen whitish buff. 



The male antennae are broad, and have forty-six rays on each side 

 lying flat ; the four rays of each joint of equal length. The female 

 antennae are of considerable breadth, and with forty-eight or fifty 

 rays on each side. 



The palpi are very short but distinct and rather slender, and the 

 spiral tongue is also distinct and composed of two flattened free fila- 

 ments.

The fore -wings are considerably emarginate along the outer mar- 

 gin in the male, and more slightly so in the female. The veins agree 

 in arrangement with the typical Saturnice. The general colour of 

 the wings is a dark livid brownish purple, thickly powdered with 

 white atoms ; the middle of each wing is occupied by a large trans- 

 parent spot, kidney-shaped in the fore-wings and oval in the hind 

 ones ; the vitreous portion is surrounded by a slender line of white, 

 which is succeeded by a yellow one, and this by a slender black line ; 

 these eyes are of nearly equal size. The fore-wings are also marked 

 near the base with an oblique white fascia, extending from near the 

 base of the fore- wings to the base of the large eye ; beyond the eye 

 is a curved white bar, internally edged with a darker bar of livid 

 purple ; the apical part of the fore-wings is brown shaded to fulvous 

 and buff; the outer margin of the wing dusky buff, with a series of 

 greenish buff spots edged with a slender brown deeply undulating 

 line ; near the tip of the wing is a black spot irrorated with white at 

 the base, from which runs a very slender and much-angulated white 

 line. The hind- wings have a fulvous edge gradually shaded to buff- 

 brown, bearing a row of dark brown catenated spots followed by a 

 slender dusky line. The under side of the wings resembles the upper 

 side, with the costa of the hind- wings white. The body is purplish 

 brown, the thorax behind with a white fascia, and the segments of 

 the abdomen have the hinder margin white. The antennae, head and 

 legs are fulvous. The antennae are broadly pennate, with the rays 

 continued to the tip. The males have fifty-eight rays (arranged in 

 double pairs to each joint), with single rays at the tip. The females 

 have also fifty-eight long rays (four to each joint), with eight or ten 

 single rays at the tip. The palpi are porrected, but do not extend 

 beyond the hairs of the clypeus.
