512 BIONOMIC NOTES 
a rather strong odour in the male. In 1876 he had said that the 
odour was faint.] 
Pinacopteryx charina, Boisd. (S. Africa, 1905). Dr. Dixey and I 
occasionally found a flowery scent in the male of this butterfly; he 
compared it to Mignonette. 
Pinacopteryx pigea , Boisd. (S. Africa, 1905). We both found a 
distinct, sometimes strong, scent in the male, like Honeysuckle. 
Belenois gidica , Godart. (S. Africa, 1905). In some of the males 
Dr. Dixey and I found a flowery scent, which he compared to that of 
roses. 
Belenois mesentina , Cram. (India, 1904). The male was found to 
have a faint, sweet, flowery scent which did not appear to me to be 
quite like that of any other insect. (S. Africa, 1905). Dr. Dixey 
found in a male a scent much like thatfof B. gidica. (Sudan, 1909). 
Males were found by me to have a slight scent, sometimes described 
as musky, but once as luscious. 
Belenois severina , Cram. (S. Africa, 1905). Both Dr. Dixey and I 
found much individual variation in the males. He compared their 
scent to sweet-briar; I thought it like that of G. hrassicae, but 
stronger and more luscious. 
Belenois thysa, Hopff. (S. Africa, 1905). We agreed that the 
males had a strong, distinct odour. Dr. Dixey compared it to that 
of roses, I rather to Bluebell ( Scilla nutans), but sometimes to 
Freesia. 
Belenois teutonia, Eabr. (Australia, 1910). A slight scent was 
suspected by me in sundry males, but nothing at all definite. 
Delias eucharis , Drury. In India during the winter of 1903-4 
I observed the scent of this species and compared it to that of 
Ganoris rapae, or sweet-briar. On that occasion I made sure of the 
scent in the male, and more than suspected its presence in the 
female. 
My more recent experience (Ceylon, 1908) enables me to speak 
with greater confidence. Of eighteen males examined a scent was 
detected in seventeen; in four of these the scent was very slight, or 
indefinable, but in twelve it was strong, or very strong, and compared 
to that of sweet-briar. Out of nine females examined in three no 
scent could be detected, but in six specimens there was more or less 
scent, but in no case was it strong; this was described as “ sweet,” 
“ dusty or musky,” and “ faint sweet-briar.” Mrs. Longstaff said of 
the last specimen “ very slight lemon-verbena; yes, perhaps more like 
sweet-briar ” ; but of another specimen she said, “ it has a little gentle 
sort of smell, (?) ginger, or (?) coarse brown sugar.”
