them. Its flight is remarkably graceful and leisurely, and on calm days higher 
than that of Danais Chrysipptis, though not nearly so extensive in range. It 
is fond of floating across open spots in the woods, flapping its wings twice or 
thrice in its course, and then of settling on some projecting twig and remaining 
for some time motionless, usually with the wings closed and hanging down- 
wards. Wlien in pursuit of a companion, or when itself pursued by the 
collector, Echeria displays the power of much more rapid motion. I have 
noted its appearance throughout the warmer months, viz., from the beginning 
of October to about the middle of April. 
The typical form figured by Stoll is that which prevails in the Cape 
Colony and in that part of Ivaffraria Proper which is near the eastern border of 
the Colony; but I took one specimen at Port Natal in the summer of 1867. 
The Variety A., with white spots in the fore-wings (first noticed by Boisduval), 
is, on the contrary, very scarce in the Colony — I only met with one at Ivnysna — 
but becomes more frequent on the Bashee River in Kaff'raria, and is the prevalent 
form at Natal. Colonel Bowker also met with this variety at Delagoa Bay 
in 1878.1 
The Variety B. above noted is in colouring much nearer to the type-form, 
and is remarkable as the only West-African (and indeed the only Tro^ncal) 
example of Echeria that is known to me. I examined the fine collection made 
on the West Coast by Lieutenant Bourke of H.M.S. Druid in 1873, and he 
distinctly recollected the capture of this solitary specimen at Fernando Po. 
Without further material it is impossible to determine whether this specimen 
represents a characteristic West- African form or is a mere aberration. 
Amauris Echeria is of special interest in relation to the mimicry by other 
butterflies of which it is the object. It may be said more than even Danais 
Chrysippus to set the fashion in South Africa. The most accurate imitator 
is the $ Fapilio Genea, Stoll, small examples of which it is almost impossible 
on the wing to distinguish from her model. Almost as good a mimic is Diadema 
mima, Trim., both sexes very closely resembling the white-spotted variety of 
Echeria. The $ Fapilio Echerioides, Tiim., is also an excellent copy ; while 
P. Brasidas, Peld. — an unstable species closely allied to P. Leonidas, Fab. — 
presents some variations which very fairly imitate the favourite pattern. Some 
examples of the Nymphaline Pseudacroia Tarquinia (Trim.), especially the 
females, also indicate a decided leaning towards the prevalent livery.
