Except in being more bronzed in the colour of the wings, this species scarcely differs 
from A. agathyrsus.

Alis supra cyaneo-nigris, anticarum dimidio basali cost striolis, fascia submedia postice

ejusdem coloris, cauda ceruleo-alba, ciliis albis. Capite maximo, ano maris fulvo bar- 
bato. Expans. alar. antic. unc. 43. 
Hab. Aru (Wallace). In Mus. Hopeiano Oxonie. 
This insect agrees so entirely with A. agathyrsus that I should have had no hesitation 
in so naming it; but the extraordinary size of the head and eyes, far exceeding those 
of any other males of the genus which I have examined, seems a sufficient character to 
allow it a distinctive specific rank, although I am aware that in certain insects which 
are distinguished by the large size of their heads there is much difference in the extent 
of this character. I know no such instance, however, amongst Lepidopterous insects.

Note.—The figure given by Hopffer is far too highly coloured. I have therefore 
given a new representation of it. It may be distinguished by the very broad conical 
central fascia of the fore wings.
