the flowers of the mango or to cinnamon. In three females out of 
four there was a similar scent. 
In Belenois gidica (cf. fig. 27, pl. 4) from South Africa, Doctor 
Dixey and Mr. Longstaff found in some of the males a flowery scent 
which the former compared to that of roses. In B. mesentina in 
India Mr. Longstaff found the male to have a faint sweet flowery 
scent which did not appear to him to be quite like that of any other 
insect. In South Africa Doctor Dixey found in a male a scent 
much like that of B. gidica. In the Sudan Mr. Longstaff found 
the males to have a slight scent, sometimes described as musky, but 
once as luscious. In B. severina in South Africa both Doctor Dixey 
and Mr. Longstaff found much individual variation in the males. 
The former compared their scent to sweetbrier, the latter thought it 
hke that of Pieris brassice, but stronger and more luscious. In B. 
thysa they agreed that the males have a strong distinct odor which 
Doctor Dixey compared to that of roses, Mr. Longstaff rather to the 
bluebell (Scilla nutans), but sometimes to Yreesia. In B. teutonia, 
examined in Australia, Mr. Longstaff suspected a slight scent in 
sundry males, but nothing at all definite. 
Mr. Longstaff found in the male of Nepheronia ceylanica in Ceylon 
a more or less distinct scent which he compared to Freesia. A female 
had a similar scent which Mrs. Longstaff compared to frangipani 
(Plumeria rubra). A male of WV. hippia from India had a very 
shght burnt-sugar scent. 
Both Doctor Dixey and Mr. Longstaff found a flowery scent in 
the males of the South African Lronia cleodora. 
In Pinacopteryx charina from South Africa Doctor Dixey and 
Mr. Longstaff occasionally found in the male a flowery scent which 
the former compared to mignonette. In P. pigea they both found a 
distinct, sometimes strong, scent like honeysuckle in the male. 
Three species of Mylothris (cf. fig. 30, pl. 4) have been examined 
in South Africa. The males of M@. agathina and of M. riippellu 
have a strong, pleasant scent exactly like that of sweetbrier. The 
scent of If. trimenia is of quite a different nature; it reminded Doctor 
Dixey of sweet peas and Mr. Longstaff of clover. 
Doctor Dixey compared the scent of the males of Synchloé hellica 
to that of gorse. Mr. Longstaff recorded a male as having a very 
slight heavy and flowery odor. Later at Cape Town he caught a 
single male with a sweet odor which seemed to him to have a resinous 
element. 
Swallowtails—Among the swallowtails (Papilionide) apparently 
the males always have an odor, but the information concerning these 
is often more or less indefinite, sometimes conflicting. The females 
commonly, always perhaps, have a musty or acid odor, and the 
males frequently a similar odor, though much less strong, which
