Imago. — Male. Upperside dark indigo-blue, glossed, and in certain lights with a 

 greenish tint. Forewing with the blue colour merging into the broad black costal and 

 outer marginal borders. Hindwing with the costal space and abdominal fold blackish, 

 outer margin with a very narrow black band ; the abdominal space outside the fold 

 darker black than the colour of the fold ; anal lobe black, with an orange spot, and a 

 few greyish-white scales along its upper side ; tail black, tipped with white. Cilia of 

 both wings black with pale tips, with a white medial line through it from the anal lobe 

 to vein 3. Underside rufous-brown, varying in shade of colour somewhat in dilferent 

 examples, markings darker brown. Forewing with a bar at the end of the cell, a 

 moderately broad discal band from near the costa to the sub-median vein, slightly 

 outwardly curved above its middle, in some examples with a patch of black suffusion, 

 joining it to the discal bar ; a sub-marginal narrower band. Hindwing with similar 

 discoidal and discal bands, the latter outwardly edged with white, composed of 

 conjoined squarish spots, passing close to the lower end of the discoidal bar, slightly 

 outwardly curved from the costa to vein 2, where it curves inwards in a large angle to 

 the abdominal margin a little below its middle, and is there prominently edged with 

 white on both sides and has a short white line close below it ; anal lobe black crowned 

 with dull orange, a white anteciliary thread on the lower half of the outer margin. 

 Antennae black, ringed with white ; club tipped with red ; frons black ; eyes- ringed 

 with white ; head and body above and below concolorous with the wings, abdomen 

 below ochreous. 



Female. Upperside paler, pale brown glossed with purple ; consequently the 

 costal and outer marginal black borders more distinct. Underside paler than the 

 male, markings similar. 



Expanse of wings, $ % 1^-^ to l-j% inches. 



Larva, in shape and protuberances, is exactly similar to that of R. scliistacea, 

 but the colour is green, with a curved, diagonal line, almost pure white, to each 

 segment ; the fifth segment is very dark green, in some cases almost black, forming a 

 band. The larva feeds on the flowers of Zizyphus xylopyrus. 



Pupa is identical with that of R. scliistacea. (Davidson, Bell and Aitken.) 



Habitat. — India, Burma, Andamans, Ceylon, Java, Borneo. 



Distribution. — The type came from Java ; de Niceville records it from Calcutta, 

 Elwes from the Karen Hills, Watson from Chin Lushai and the Chin Hills, Mackinnon 

 and de Niceville from Mussuri, de Rhe-Philipe from Lucknow, Aitken and Comber 

 from Matheran, near Bombay, Davidson, Bell and Aitken from Karwar ; we have many 

 examples of both sexes from Java, Port Blair, the Khasia Hills, and other localities,
