$ 2 • Upperside umber-brown with a rich silky gloss. Fore 

 wing : the discal fascia on the underside showing through 

 obscurely, and a pale preapical spot, both more distinct in the 2 • 

 Hind wing with a postdiscal series of more or less obscure black 

 spots, dorsal margin pale. Both fore and hind wing with an 

 indistinct subterminal lunular border. Ocelli and border more 

 distinct in the 2 • Underside paler, the wings with a subterminal 

 pale lilacine line. Fore wing : an obscure brown band across the 

 cell, a pale, broad, oblique discal, and a similar subapical transverse 

 fascia not reaching the dorsum, the latter two margined anteriorly 

 w r ith white. The fascia better defined in the 2 • The outer 

 fascia in the cf with three, in the 2 with four superposed ocelli. 

 Hind wing : four irregular, sinuous, transverse lilacine lines, the 

 outermost bordered by a zigzag band of dark brown ; a postdiscal 

 curved series of white-centred black ocelli, of which the second 

 from the tornus and the apical ocellus are the largest. Each 

 ocellus with an inner ochraceous, intermediate brown, and outer 

 lilacine ring. Dry-season specimens have the underside darker, 

 the markings broader, the ocelli with larger blurred centres. 

 Antennae, head, thorax and abdomen brown ; antennas ochraceous 

 at apex.

The form next described is very close to, if not a mere race of 

 L. sidonis, but as, according to Mr. Doherty, the genitalia of the 

 two forms differ, I have kept them separate.

<S 2 • This form differs from L. sidonis as follows : — Terinen of 

 hind wing nearly entire, not much scalloped. Upperside uniform 

 silky umber-brown. Hind wing without trace of postdiscal black 

 spots. Underside comparatively darker, more uniform, the 

 markings very obscure. Genitalia of <$ : " Prehensores close to 

 those of sidonis. The uncus is more bent down, appearing truncate 

 from above and flattened laterally, while in sidonis it appears 

 acute from above and is cylindrical" {Doherty). 



Exp. c? 2 55-58 mm. (2-17-2-3").
