that they have deceived not only practised collectors, but experienced 
entomologists, so that it was by no means uncommon until recently to 
find even in public collections specimens of the models and of their 
copies placed together, in the mistaken belief that they were represen- 
tatives of one and the saoie species. There is thus no difficulty in 
understanding how complete is the deception in the field, where the 
habits and flight of the mimicking insects are more or less assimilated 
to those of the protected species mimicked, which inhabit the same 
districts, and very often haunt the same spots. 
Of the four known South-African species, Fs. Trimenii and Ps. 
imitator respectively imitate the red black-spotted Acroea Acara and 
the black yellowish- or white-banded Planema Aganice, — the latter 
affording an instance of remarkably exact imitation. The males of the 
remaining two, Fs. Tarqidnia and Fs. Felagoce, present a much less 
close resemblance to the same Flanema ; while their females, singularly 
enough, are modified in distinct relation, respectively, to the Danaine 
Amauris Eclur'm and A. Ochlca. In range, Tarquinia seems farthest 
distributed, occurring at Natal, on the Zambesi, and in Usambara; 
Trimenii inhabits Natal, Delagoa Bay, and Zambesia ; Imitator has 
been found only in Natal ; and Ddagom inhabits the place after which 
it is named. All appear to be rather scarce insects, but it is not 
unlikely that they are less rare than they seem, — their disguise render- 
ing them very apt to be passed over among the abundant Acrceince.

^ Frownish-Uack, vjith wJiite and yellowish-wliite hands. Fore- 
wing : an outwardly arched band of four white spots, of which the first 
(much smaller than the others) is in discoidal cell close to its extremity, 
and the fourth (the largest) between first and second median nervules ; 
two elongate yellowish- white spots, one on each side of submedian 
nervure, forming an irregular patch on inner margin rather beyond 
middle (of these the upper spot is sometimes very much reduced or 
almost obsolete) ; between white band and apex two obliquely-lying 
Bubquadrate white spots, one on each side of first discoidal nervule ; a 
fine linear edging of pure-white along costa from a little beyond 
middle, ending at apex in a conspicuous white spot extending to the 
cilia immediately adjoining. Hind-wing : crossing middle, a broad 
yellowish- white band, beginning close to costa, opposite inner- marginal 
patch of fore-wing ; of this band, the inner edge, not far from base, is 
slightly irregular, — the outer edge regularly and sharply dentated by 
inter-nervular black rays extending from hind-margin. In hoth wings^
