1865.] MR. A. G. BUTLER ON SIX NEW BUTTERFLIES. 667 
tains of Semién, in Abyssinia, in an absolute altitude of from 10,000 
to 11,000 feet. The only individual I ever shot was an adult female. 
It was in the month of February in 1863. I did not succeed in ob- 
taining a male, these birds living exclusively near the margins of 
colossal precipices, into which, when once alarmed, they dive with 
a bewildering velocity. The drawing was made from the freshly 
killed bird, several specimens of F. erkelii and F. gutturalis being 
near me at the time.

1. HererRocurRoa saALmonevs. (Fig. 1, p. 668.) 
Upperside—front wings, basal half rich brown, varied with black 
lines ; apical portion deeper-coloured, with a black submarginal line 
along the outer margins ; crossed beyond the middle by an irregular 
bright orange belt. Hind wings rich brown, crossed by five broad 
black bands converging towards the anal angle, the two nearest the 
base divided in the middle; a narrow submarginal black line along 
the outer margin. 
Underside—front wings golden reddish brown, anterior margin 
and anal angle paler; crossed beyond the middle, from the anterior 
margin to the anal angle, by a broad, oblique, irregular silver band, 
broader above than below, interrupted by the nervures, which are 
fuscous, and by a faint ochreous streak crossing the space between 
the first and second median nervules ; three bluish-silver spots, placed 
obliquely between the nervules and extending from near the apex to 
the central silver band ; a submarginal row of silver spots between 
the nervules, close to the outer margin, the two lowest ones lunular ; 
a large wedge-shaped bluish-silver patch margined with rufous at 
the base, interrupted by the median nervure and an oblique orange 
streak ; a smaller curved elongate patch, intersected by a rufous 
lunular line, and margined with rufous, closing the cell; a small 
bluish-silver spot below the base of the third median nervule, a second 
oblong spot of the same colour below the middle of the same ner- 
vule, and a small silver lunule just above it margined on its inner 
edge with rufous. Posterior wings golden reddish brown, basal half 
and anterior margin paler; crossed by four irregular violaceous 
silvery bands, bordered with rufous, converging towards the anal 
angle and interior margin; the second from the base short, bounded 
by the median nervure, its upper half contiguous to the third band; 
the fourth somewhat dusky, broadest in the middle; a submarginal 
row of silver lunules intersected by a rufous line along the outer 
margin, between the nervures.
