^. — Head white, front blackish blue. Prothorax, thorax and pa- 

 tagia white. The prothorax has two large steel blue patches edged 

 with black. The thorax has six similar smaller patches arranged in 

 two rows. The patagia have a patch on the inner edge, constricted in 

 the middle, the hindermost portion having a white centre. Abdomen 

 blue black above with a narrow yellowish lateral line ; whitish beneath 

 with a ventral and lateral row of minute black spots. Thorax beneath 

 white. Legs white ; coxae and inside of anterior pair steel blue. Tip 

 of tibia:? and tarsi of remainder of the legs steel blue, except the tarsi 

 of the hind pair which are partially white. 



Wings white, thinly scaled, with many black spots showing metallic 

 blue reflections, especially on the costa. The spots on the primaries 

 are arranged as ibllows. A terminal, interspaceal series of lunate 

 spots. Five large spots on the costa enclosing a narrow white line. 

 The second of these from the base forms one of a transverse curved 

 band of four spots, of which the two near the inner margin have white 

 centres. Inside this band the wing is irregularly mottled with black. 

 The third costal spot forms one of a similar band of seven spots, of 

 which two lie at the end of the discal cell, and are black, while the 

 rest have white centres ; the one on the inner margin being partially 

 fused with the similar spot of the first band. There is a single spot 

 just outside the discal vein, and a series of four spots beginning at the 

 base of the 3rd median and going to the fourth costal spot. I'here is 

 also at the anal angle a large dark spot above and below the subme- 

 dian vein, from which a double row of spots parallel with the outer 

 margin goes towards the costa, the inner row extending only to the 1st
