Morphinae. 
[Thaumantis diorcs, Doubl. (Assam, 1881). Wood-Mason notes 
that the scent-fans of the male are vanilla-scented.] 
[Stichophthalma cctmadeva, Westw. (Assam, 1881). Wood-Mason 
notes : “ The gland, covered by a patch of modified scales, and by 
an erectile wisp of hairs on each hind-wing in the male, secretes a 
fluid that gives out a pleasant odour distinct from, but so faint as 
barely to be perceptible in the presence of, a much stronger odour 
(resembling that of sable fresh from the furrier’s shop), which is 
common to the two sexes.”] 
\Morpho hercules, Dalm.; M. epistropkis, Hiibn.; M. menelaus, 
Linn.; M. achilles, Linn.; M. adonis , Cram.; and M. cytheris , Godart. 
(Brazil, 1878). Fritz Muller recorded that the males of all these 
butterflies produced a very distinct odour, which in the last two 
species was most agreeable, resembling vanilla.] 
Brassolinae. 
[Fritz Muller (Brazil, 1878) noted very distinct odours in the 
males of various species of Caligo, Opsiphanes and Dasyophthalma , 
the odour being particularly strong in the latter.] 
Nymphalinae. 
\Myscelia or sis, Drury. (Brazil, 1878). Fritz Muller observed 
an unusually strong odour in the males of this species, as well as 
in those of the next following.] 
[.Epicalia acontius, Linn. (Brazil, 1878).] 
[Ageronia arethusa , Cram. (Brazil, 1878). Fritz Muller noted a 
rather strong odour in the male.] 
[Didonis biblis, Fabr. (Brazil, 1878). Fritz Muller noted in 1876 
that the male had a pleasant odour like heliotrope, the female an 
unpleasant smell; in 1878 he wrote : “ so far as odours are concerned 
[this is] the most interesting of all butterflies that I know.” There 
is a strong disagreeable odour common to both sexes. The males have 
in addition two other scents comparable to heliotrope and musk 
respectively; the latter faint.] 
I much regret that in the specimens of this handsome, and very 
conspicuous butterfly, which passed through my hands during the 
winter of 1906-7, I did not notice any scent. 
\Prepona laertes , Hiibn. (Brazil, 1878). Fritz Muller noted a 
distinct odour in the male. In 1876 he had described this as “a 
not strong but unmistakable odour, like a bat.”] 
Byblia goetzius, Herbst. (S. Africa, 1905). Dr. Dixey found in 
the males a very distinct and agreeable odour of sweet chocolate 
with a suggestion of vanilla. I found a similar scent in the only
