A. jodutta, in which all the white markings except the subapical 
bar are replaced by vellowish. An example of this latter form of 
the female jodutta was captured on July 24th (Table II). 
Dr. JORDAN's conclusions, based on a study of the male geni- 
talia, are thus supported by a study of the Entebbe material. 
But inferences so important should be submitted to the ultimate 
test supplied by the method of breeding before they are accepted 
as final. However firm the proof, — and Dr. JORDAN’S is certain 
to be of the firmest, — the cooperation of various lines of evid- 
ence is demanded by a conclusion so far-reaching as one which 
unites into a single interbreeding community, continuous over 
nearly the whole of the forest areas of Africa, all the divergent 
forms of the most important mimetic group in the genus Pseud- 
acrea, — from imitator (1) in the south-east and rogersi (2) in the 
east, through the Uganda forms, hodleyi, terra, and obscura, to 
the numerous mimetic modifications of eurytus L., on the west 
coast and the great tropical forest region of the continent.

Dr. JORDAN concludes that this species, which is rare at 
Entebbe, is entirely distinct from the forms of Ps. hobleyi. Its 
superficial resemblance in both sexes to the far more abundant 
males of Ps. hobleyi is so extraordinarily close as to suggest that 
there has been a secondary mimetic approach. Such an interpret- 
ation is more probable than one based on the hypothesis of arrested 
divergence; for it is unlikely that details in the shape of the fore 
wing bar in one sex of a single member of the hobleyi group are 
specially ancestral, and it is these very details that are so pre- 
cisely reproduced in both sexes of Auenowi I may add that the bar 
of the male hobleyiis extremely variable in shape, and that it is 
the commonest and most characteristic form which appears in the 
less variable Auenowi.
