verse, dark lines ; the cliscocellular transverse streak on the forewing as on 

 the upperside ; a prominent, transverse, discal band across both fore and 

 hindwings, very broad at costa of forewing, narrowing to dorsum ; 

 similarly, but not quite so broad at costa of hindwing, narrowing to the 

 dorsum, its inner margin sinuous, its outer straighter, both obscurely 

 defined by dark lines ; faint lunular markings beyond on terminal half of 

 both wings ; the black spots in the transverse discal series on the hind- 

 wing very small. Antennse brown ; head and abdomen more or less fulvous 

 tawny ; thorax with bright pale green pubescence ; beneath pale ochraceous. 

 Sex-mark : the veins on the upperside of the disc of the forewing black ; 

 veins 5, 6 and apical portion of 7 with very narrow short bands of specializ- 

 ed scales on each side ; no such scales on the hindwing. Female upperside 

 similar, the black edging to the apex and termen conspicuously broader as 

 are all the black markings. Underside similar; ground colour paler, more 

 ochraceous, not suffused with purplish, the markings similar to those in the 

 male, but the inner margin of the discal band more than sinuous, zigag ; 

 Antennae, head, thorax, abdomen as in male. 



Dry-season form.- — Similar to the wet-season form but on the upperside 

 the ground colour is a shade duller and paler, the markings more restricted 

 and of a dusky black. On the underside the transverse discal band is some- 

 times margined outwardly with a diffuse dusky black band, the white 

 being sometimes completely obscured by a suffusion of the ground colour. 



Larva. — The larva is similar to that of Cupha in general aspect, the body 

 being set with spines in the same way. The head is round and slightly 

 bilobed, yellow in colour, shiny, smooth, with two exclamation-marks, half 

 the length of face, down each lobe and some markings about the eyes, 

 black. Segment 2 is narrower than the head by a good deal and is yellow 

 in colour with a dark dorsal line. Spiracles are large, oval, black with a 

 light central slit, shiny, the lower half hidden often by a fold near base of 

 subspiracular spine. On segments 2 and 3 there is a subdorsal and 

 lateral setiferous spine on each side about 7 mm. in length ; on segment 

 4 there is a subdorsal one and a- lateral one near front margin ; segments 

 5-12 have each a subdorsal, lateral and subspiracular setiferous spine on 

 each side ; segment 13 has one subdorsal on each side, the anal segment 

 one, lateral, before the hinder margin. The spines are all equal in size and 

 black in colour, shiny, except the anal four which are white ; anal segment 

 is yellow. Colour of the body is dark-brown with a violet tinge and with 

 a subdorsal, lateral and subspiracular white longitudinal line, the spines 

 being placed between these lines ; abdomen green. L : 25 mm.; B : 6 mm. 



Pupa. — Is similar in shape to that of Cupha, but is bone-white all over in 

 colour and has many more curved processes. Head with very prominent 

 eye-balls underneath, rounded moderately at sides, rather bowed ven- 

 trally ; a small point in front of each eye curving upwards ; segment 2
