base and inner margin to the second submedian pale-yellow, merging 

 into orange-red or flame-scarlet (ii), which also colours the other spots. 

 A long stripe in lc, not reaching margin ; a short stripe below the cell ; 

 a similar stripe in lower half of cell, reaching beyond vein 2, and a 

 longer stripe next it in upper part of cell. 



All these stripes separated distally by the ground-colour, and merged 

 together proximally in the yellow basal colouring. Three discal spots 

 in 2-4, the middle one projecting below the others, the distal one the 

 smaller. Two small submarginal spots in cellule 2. Costa edged with 

 pale-yellow at base for a short length. Anal angle tinged with orange- 

 red. Veins edged with deep violet. 



Underside markings similar to upperside. Fore wing with basal 

 stripes on costa and on first submedian. Discal markings flame- 

 scarlet ; an oblong spot in middle of cell, a long stripe below cell, not 

 reaching vein 2, an elongate spot in middle of lb. Other markings 

 as above. Veins heavily bordered with cerulean-blue except at apex. 

 Hind wing with markings as above but a long stripe in lb, separated 

 from the one in la and lc, and nearer the inner stripe, interspaces shot 

 with violet-blue. A small spot in 6 near the cell. Veins striped with 

 violet-blue. 



Head and antennae black, frons and palpi pale-yellow, collar and 

 patagia pale-yellow. Abdomen pale-yellow ringed with deep-violet. 

 Legs fuscous, striped with deep-violet on the outside and with pale-

3. Eusphalera janthina sp. nov. 



Distinct from any other form, and bearing a close resemblance to 

 the G-eometrid Milionia dispar Prout, found in the same locality. 



? . Upperside of fore wing orange-yellow to orange with a broad 

 black apical area. The orange area reaches beyond cell ; outer edge 

 clearly defined, reaching the narrow black costal edge beyond the 

 middle and the outer margin at end of lower submedian, lower part 

 curved distad. An ill-defined black patch on inner margin before the 

 tornus, reaching upper submedian. A series of five small apical dark 

 metallic blue spots, arranged as in other species of the genus. Hind 

 wing with fuscous-black ground-colour. Basal area to base of vein 3
