by somewhat irregular subterminal and terminal rows of purer 

 white small spots ; the spots in the subterminal row are paired, 

 and in both rows are incomplete towards apex of wing. Underside 

 dark hair-brown, deep blue-black along posterior half of termen of 

 both fore and hind wing ; markings as on upperside, but larger 

 and more clearly defined, the streak from base in interspace 1 on 

 the fore wing wanting, additional streaks in interspaces 7 and 8 

 and at apex in hind wing. Antennae black ; head, thorax and 

 abdomen black above ; the abdomen conspicuously barred with 

 white on the sides ; thorax spotted with white beneath. 



The 2 is polymorphic. 

 First form. — Upperside fuligin- 

 ous bluish black. Eore wing : a 

 transverse white obscure spot at 

 apex of cell, a short very broad 

 oblique white discal band or patch 

 from costa to interspace 2, and a 

 terminal series of obscure white 

 dots. Hind wing: white streaks 

 in cell and interspaces 1 a to 6, 

 and subterminal and terminal rows 

 of obscure white spots. Under- 

 side similar, the markings somewhat 

 larger and more clearly defined. 

 Second form. — Closely resembles 



the first form, but the white mark- 

 Fig, ^.-^npus^itkef-ses, $. ingg? especially on the hiud wing ^ 



more extensive. 



Third form. — Upperside. Eore wing deep indigo-blue, the apical 

 half of the wing suffused with purple, traversed by the dark veins 

 and by a terminal series of obscure purplish- white spots. Hind 

 wing dark cinnamon-brown, an obscure terminal series of white 

 specks, more distinct at the tornal angle. Underside dark cinna- 

 mon-brown, the terminal series of spots on both fore and hind 

 wing far more clearly defined, in addition a subterminal row of 

 white spots on the hind wing; the abdomen beneath marked trans- 

 versely with white. 



Fourth form (alcathoeoides, de N.). — Similar to the above, but 

 on the upperside the fore wing hair-brown, very slightly suffused 

 with purple, the hind wing with subterminal and terminal series 

 of white spots, the subterminal spots sometimes elongate, more 

 often round. 



Fifth form (nyctelius, Dblday., A. M. IN". H. xvi, 1845, p. 182).— 

 Similar to cinnamomeus, Wood-Mason, but fore wing with a 

 terminal series of obscure and ill-defined white streaks ; hind 

 wing with the posterior half white, traversed by the dark veins, 

 the white curving upwards, reaching the apex of the wing, some 

 obscure dark terminal marks between the veins.
