EXTRACTS FROM THE PROCEEDINGS 
OF THE 
ENTOMOLOGICAL SOCIETY OF LONDON 
(Fepruary 7TH—Marcu 21st, 1906). 
—<———— 
Wednesday, February 7th, 1906. 
Dr. F A. Drxry exhibited specimens of South African 
butterflies captured by himself and Dr. Longstaif, and re- 
marked upon them as follows :— 
“It may be remembered that at a recent meeting of the 
“Society (Proc. Ent. Soc. Lond., 1905, pp. liv—lix), I gave some 
account of the scents observed by us in South African Pierines, 
calling attention to the fact that they were practically without 
exception of an agreeable character and confined to the male 
sex. On the present occasion I wish to speak of the perfumes 
detected by us in butterflies belonging to other groups ; some 
of these odours having a similar character to those of the 
Pierines, while others belong to a different category. 
“ Mycalesis safitza, Hew. ¢. On separating the fore- and 
hind-wings, so as to expose the well-known ‘tufts,’ I at once 
perceived a strong odour of chocolate, perhaps combined with 
a trace of vanilla. This I noted at the time as ‘one of the 
strongest butterfly scents known to me.’ I found no odour in 
the female. Dr. Longstaff also detected a ‘ chocolate scent, 
not strong,’ in the tufts of the male. 
“Two males of Mycalesis perspicua, Trim., examined by Dr. 
Longstaif, emitted a ‘very strong treacly odour—quite distinct 
from the scent of M. sajfitza.’ To my perception the scent was 
rather of the chrysippus order, with a suggestion of burnt 
sugar or treacle. We had no opportunity of testing the 
female. 
“Two male specimens of Yphthima ctonia, Hew., and three 
of Pseudonympha cassius were tested by me with a negative 
result.
