4, Mr. R. Trimen on 
ably African, and I think not unlikely to prove a native 
of some dry and elevated part of the S. W. tropical area. 
The pure-white underside of the hindwings and apices of 
the forewings is very striking and peculiar, and must 
make the butterfly highly conspicuous in repose; and in 
life there can be little doubt that the rufous of the entire 
upperside and of the forewings on the underside was of a 
much brighter and livelier tint than is now seen in the 
specimen—red colouring in the Acrwx invariably fading 
greatly after death. 
Fam. LYCANIDA. 
Lycena gigantea, sp. n. (Pl. I, figs. 2, $; 3, 2). 
Exp. al.($)2in. 1lin. ; (9) 2in.25lin. Allied to LZ. leucon, Mab., 
but much larger. 
¢. Rather dull pale lilacine-blue, with a pinkish tinge; the 
conspicuous spotting of the underside showing faintly through 
the wings; a rather strongly-marked black hindmarginal edging 
streak ; cilia blackish, faintly tipped with whitish and mixed with 
whitish at posterior angle of forewing, and between 2nd median 
nervule and anal angle of hindwing. Forewing: an almost linear 
terminal disco-cellular black striola, which looks diffused on both 
sides owing to the large broad corresponding marking on the under- 
side showing through. Hindwing: between Ist and 2nd median 
nervules a hindmarginal small blackish spot, scaled with bluish- 
white, and bounded internally by a very faint stain of orange; a 
similar but much smaller and fainter hindmarginal spot immediately 
above submedian nervure; at extremity of Ist median nervule a 
short rather thick black tail. UNpbErRsipE.—Dull-white, with con- 
picuous black spots ; costal border of both forewing and hindwing, 
and neuration generally, ochre-yellowish, and a tinge of the same 
tint over hindwing generally. Forewing: terminal disco-cellular 
spot much the largest on the entire underside, very broad, reniform ; 
discal series irregular, consisting of 8 spots—of which the 1st (on 
costa), the 7th, and the 8th (geminate, below Ist median nervule), 
are much smaller than the rest, and in a line with the round 2nd and 
5th spots—the round 3rd and the much larger and obliquely-elon- 
gated 4th are beyond the rest,—and the ovate 6th (between Ist and 
2nd median nervules) is before the rest; a well-marked submarginal 
black streak, interrupted regularly on each nervule, from costa to sub- 
median nervure; hindmargin edged with a sharply-defined thin 
black line. Hindwing: a sub-basal series of three round spots—of
