fresh, a scent much like that of B. gidica. In a second 
specimen no odour was detected. 
“ Belenois severina, Cram., g shows, like Eronia cleodora, 
much individual variation in the matter of scent. An odour 
is, however, nearly always present in greater or less intensity, 
and to my mind is of the same general character as that of 
G. rape, giving a decided suggestion of sweetbriar. Dr. 
Longstaff, who also finds great individual differences in 
intensity, considers the scent to be ‘like that of G. brassice, 
but stronger and more luscious.’ I have tested the female, 
with negative results. 
“ Belenois thysa, Hopft., ¢, has a strong, distinct odour, 
which appears to me to be like that of roses. Dr. Longstaff 
notes it as a very sweet scent; in one case comparing it to 
that of Scilla nutans, in other cases to that of Freesia. 
“The scent of Belenois zochalia, Boisd., ¢, is not as a rule 
very powerful. It seems to me to be of the sweetbriar order, 
including the scent of the flower as well as of the foliage. It 
was more distinct in a worn specimen than in two fresh ones 
examined on the same day. Dr. Longstaff found a ‘faint 
flowery scent like that of G@. brassicx’ in the single individual 
he tested. 
“ Pinacopteryx charina, Boisd., ¢, has a perfume like a whiff 
of mignonette, seldom strong and often absent. Of nine males 
tested at different times by Dr. Longstaff, only one had a 
decided odour, which he records simply as ‘ flowery.’ 
“In Pinacopteryx pigea, Boisd., ¢, the scent is distinct, in 
some cases strong. It appears to me to resemble honeysuckle 
—a comparison in which Dr. Longstaff concurs. One of my 
specimens had an odour more suggestive of Philadelphus, and 
the scent of one of Dr. Longstaft’s was noted by him as ‘sweet 
and spicy.” The female was found by me to be odourless. 
“The scent of Mylothris agathina, Cram., ¢,though varying 
somewhat in intensity in different individuals, is generally one 
of the strongest and most distinct in the whole range of 
Pierine odours so far as I am acquainted with them. To both 
Dr. Longstaff and myself it appears to be exactly that of 
sweetbriar. It is a pleasant and refreshing perfume, and is 
easily perceptible even when the butterfly is held in the hand
