regards both tint and breadth. Professor Poutron had 
believed that these “windows” of Xallima represented holes 
gnawed by larve and that the altered marginal zone repro- 
duced the effect of the attacks of fungi entering along the 
freshly exposed tissues of the edge. But he now desired 
to withdraw his earlier hypothesis in favour of the more 
probable and convincing suggestion made by Mr. Grove. The 
origin of the suggestion is of some interest in relation to the 
meetings of their Society and other associations which pro- 
mote the intercourse of naturalists. Professor Poutton in 
the course of the ‘‘ Huxley Lecture,” recently delivered by 
him in the University of Birmingham, had explained his 
hypothesis and illustrated it upon the screen. Mr. W. B. 
Grove heard the lecture and forthwith proceeded to develop 
a sounder hypothesis. 
Professor Poutton also showed a photograph of the fungus- 
like marks on the wings of the Oriental Kallimas, prepared 
under his direction by Mr. Alfred Robinson of the Oxford 
University Museum. The photograph was taken with oblique 
illumination, and shows, somewhat magnified, the tall up- 
standing scales which form the centre of each well-marked 
patch, as well as the pronounced shadow cast by them. They 
doubtless represent, in form as well as in colour, the fructifica- 
tion in the centre of a patch of leaf-attacking fungus, perhaps 
the very kinds which at a later stage of their development 
produce the “ windows” represented on another part of the 
wing-surface, perhaps some other common tropical Cryptogam. 
Dr. G. B. Lonestarr read the following observations on 
scents in the male of Gonepteryx :— 
**At Hammam Meskoutine, Algeria, on March 15th, 1905, 
while examining my captures towards the close of the day 
prior to writing the data on their envelopes, I was struck 
with the sweet scent of a ¢ Gonepteryx cleopatra, L. All 
the three dead specimens which I had taken that day had 
the scent, but in two it was faint. On March 19th, at 
Bougie, I confirmed this in a living specimen, describing the 
scent at the time as ‘sweet, rich, thick—suggesting Freesia.’ 
At Hammam P’ihra I submitted living ¢ cleopatra to four 
ladies; one could not detect the scent, another could not
