the outer margin. UNDERSIDE brown. Forewing with an indistinct- band across the cell, a white 

 spot beyond the middle of the costal margin part of a brown band which crosses the wing, 

 a second white spot near the apex, and below it three black spots dotted with white. Hind- 

 win'^ crossed by several lines of silvery white, followed by a band of seven black ocelli ; 

 the first (at the costal margin), and the frfth large, two at the anal angle touching, each with 

 a white pupil and rufous iris, bordered with [brown, and then] silvery white ; a subniargina! line 

 of silvery white ; the margin rufous, bordered on both sides with black." (Haoifsoii^ 1 c.) 

 On the underside of the hindiviu^ the silvery white submarginal line is narrow at the apex, and 

 much dilated at the anal angle ; and on each side of the series of ocelli is a broad di^rker and 

 brighter brown edging to the silvery lines which enclose it. The fore-Mino has two narrow 

 yellowish submarginal lines. The cilia are dotted with whitish. The female differs from the 

 male on the uiterside in having the ground-colour immediately within tlie marginal lines 

 somewhat darker, more especially so on the kin hoing, where it forms a distinct submarginal 

 band. The ocelli also on tlvxt wing are more distinct. The outer margin of both wings are 

 also somewhat more deeply scalloped. Under&ide as in the male. 



L. siibiiis'xs a somewhat variable insect. Some specimens from Sikkim are smaller 

 than L. sitLrea, the forewing as immaculate on the upperside as in that species, and the 

 hindwing in some of these small specimens shews no sign of the submarginal series of 

 blackish round sjiots, which are distinct in other specimens quite as small, and in the larger 

 ones. On the underside of the forewing there is every gradation from a spotless cell to 

 orve bearing a prominent transverse violet bar at its middle, on both sides margined with 

 darker brown than tlie ground-colour. Specimens from Mussoorie have the upperside quite 

 immaculate, the silvery undulating lines on the underside of the hindwing are far duller and 

 altogether less prominent than in more eastern examples, while in the Kulu specimens these 

 lines are obsolete ; and in all the Western Himalayan specimens the underside of the forewing 

 has no trace of the bar across the cell. 



Mr. A. Graham Young took three specimens of L. sidonis on the Tihir Pass in Kulu 

 in Jnly ; Colonel Lang took a few at Mussoorie in June ; in Sikkim, at from 5,000 to 7,000 

 feet elevation Mr. de NiceviUe took it most commonly in roads through forests, in October ; 

 and the late Mr. Cock took it at Shillong in July. It is far commoner in the Eastern tl>an in 

 the Western Himalayas.

L. maitrya, de Niceville, Joorn. A. S. B., vol. xlix, pt. ii, ?. 245 (1880). 



Habitat : Jalauri Pass, Narkunda, N.-W. Himalayas ; Sikkim, 



Expanse : 21 to 2 '2 inches. 



Description : Male: Upperside deep shining brown. Cilia marked with ochreous 

 at the interspaces. Forewing crossed beyond the cell by a pale ochreous, outwardly curved 

 band, narrowest and most distinct at the costn, almost obsolete on reaching the third median 

 nervule. A subapical trifid spot divided by the subcostal nervules. niudwingWwXx the ocelli below 

 showing through indistinctly in black spots, and a hardly perceptible submarginal series of black 

 lunules. Underside. 7^?;r7w/«^ with a prominent outwardly curved bar, extending across the cell 

 just beyond its middle ; the band beyond the cell of the upperside, but much more distinct, 

 both ochreous. The trifid subapical spot as above but whitish, below which are four minute 

 white dots, the remains of obsolete ocelli, one on each interspace ; some indistinct marginal 

 lines. Hindioing crossed by four very irregular lilascent lines, the first pair basal, the second 

 discal, and enclosing the disco-cellular nervules, which are margined on both sides with 

 lilascent. The innermost line of this pair is inwardly narrowly, and the outermost line outwardly 

 broadly margined with a deeper shade of brown than the ground. A submart;inal band of 

 six ocelli, the first four from the apex joined, the fifth separate, the sixth small and geminate ; 

 these ocelli are all very indistinct, and have lilascent pupils, and are outwardly margined with 

 that colour. An almost obsolete lilascent submarginal line dilated within the first median 

 net-vule, and extending up the abdominal maiijin, outwardly boidercd, especially at the anal angle, 

 ■with a rufous line.
