in the outer row, the two marks correspondingly situated are 
altered and expanded into very broad bright orange lunules ; imme- 
diately before fuscous line bounding hind margin a more or less 
conspicuous white line, broken by nervules into portions which 
form imperfect irregular rings in combination with the outer sub- 
marginal row of white marks; externally bounding the two broad 
orange lunules are two conspicuous black spots; cilia white, tipped 
with grey, and with grey linear nervular interruptions. UNDER 
SIDE.—As in 9, but slightly browner in tint, and with all the 
white-edged markings rather darker. Fore wing; Small white- 
ringed subcostal spot before discal series—so rare in g —almost 
always present and well defined. 
The ¢ differs remarkably from the ¢ in her rounded 
wings, which are not prominent either at apex of fore 
wing or anal angle of hind wing, but with decidedly 
convex hind margins. This feature is one of those dis- 
tinguishing it from the ¢ of its near ally, L. Barkeri, 
n. sp., the others being the darker ground colour and 
deeper blue above, the absence of any whitish discal 
markings on the upper side of the fore wings, the large 
and well-developed second (anal-angular) orange lunule 
in the hind wings, the small white-ringed costal spot on 
the under side of the fore wings, and the additional 
inner-marginal spot (8th) in the discal row on the under 
side of the hind wings. 
Though evidently nearly related to L. Cnejus, Fab., 
a native of the Oriental and Australian regions, L. Osiris 
is decidedly distinct. The gs upper side is of a deeper 
violaceous with a marked cupreous gloss, and presents 
two conspicuous orange lunules internally bounding the 
two black hind-marginal spots of the hind wings. The 
? has the upper side colouring (both the fuscous ground 
and the blue discs) of a much deeper tint, with much 
broader and brighter orange lunules in the hind wings. 
On the under side the resemblance to Cnejus is in both 
sexes very close, the only notable difference being the 
straighter, less interrupted, discal fascia in both fore and 
hind wings. 
As noted above, Osiris varies greatly in size, especially 
in the 2, where the range in expanse of the fore wings 
iszin. A dwarf ¢ from Delagoa Bay is rather under 
lin. in expanse. Both sexes occasionally present an 
unusually dull under side, with all the markings reduced 
in size, and more or less indistinct; this is possibly a
