the base o the wings. Fore wing : two or three spots obliquely 

 across the cell, a larger spot at its upper apex, the costal margin 

 from base (the collar broadened towards the apex), and the 

 terminal margin very broadly, dark brown ; on the inner side of 

 this broad brown terminal edging there is a transverse incomplete 

 discal series of dark brown spots, followed bv an irregular trails- 

 verse series of brown lunules, both these merge anteriorly and 

 posteriorly into the brown on the terinen ; lastly superposed on 

 the brown terminal edging is a more or less complete, transverse, 

 subterminal series of lunules of the ochraceous ground-colour, 

 reduced in some specimens to only two or three lunules above the 

 tornus. Hind wing : terminal half or more dark brown, with an 

 inner postdiscal and an outer subterminal series of more or less 

 lunular spots of the ochraceous ground-colour; the postdiscal series 

 consists of only four spots in interspaces 1 to 4, the subtermiual 

 series is complete to interspace 7, the spots larger, that in inter- 

 space 3 elongate, outwardly conical ; tail tipped with ochraceous. 

 Underside : ground-colour a deeper richer ochraceous. Pore wing : 

 cell and basal area with a number of irregular cinnamon-brown 

 spots, followed on the terminal half by three transverse series of 

 more or less irregular and incomplete lunular cinnamon-brown 

 markings and a narrow brown terminal edging. Hind wing : 

 basal area with a transverse series of three spots, a large spot at 

 apex of cell, the bases of interspaces 1, 2 and 3, followed by three 

 more or less complete but irregular series of lunular markings, 

 cinnamon-brown ; superposed on the inner discal row of brown 

 lunules is a transverse series of snow-white crescents, conspicuous 

 only in interspaces 1 and 2, but barely indicated anteriorly. 

 Antennae dark ochraceous brown ; head, thorax and abdomen 

 ochraceous, the thorax posteriorly and basal half of the abdomen 

 olivaceous ; beneath : head, thorax and abdomen brighter ochraceous. 

 2 . Ground-colour paler, base and cell of fore wing on upperside 

 shaded with bright very pale cinnamon ; markings similar both 

 on the upper and under sides, but less clearly defined ; the costal 

 margin of fore wing on the upperside ochraceous almost to apex, 

 not brown ; the subterminal series of ochraceous lunules on the 

 upperside of the hind wing very large, separated from one another 

 only by the brown along the veins. Antennae, head, thorax and 

 abdomen similar, but paler.
