[Delias hierte, Hubn., var. indica, Wallgr. (Cachar, 1881). Wood- 
Mason noted that both sexes have a strong, grateful musk odour.] 
Delias nigrina , Fabr. (Australia, 1910). A male was thought by 
me to have a very slight scent. 
Leptophohia aripa , Boisd. (Venezuela, 1907). Seven males out of 
eight examined had a distinct or even strong scent, which I compared 
on various occasions to Orange, Freesia , and Mignonette. 
Pieris calydonia , Boisd. (Venezuela, 1907). Three males of this 
species—all that I captured—had a distinct flowery scent, in one 
described as “ like that of G. brassicae” in another as “ somewhat 
sickly.” 
Pieris {Perrhybris) sp.—apparently undescribed—near sevata, Feld. 
(Venezuela, 1907). The only specimen taken, a male, had a “faint, 
sweet, flowery scent ” (see above, p. 320). 
Gatophaga paidina, Cram. (Ceylon, 1904, 1908). The results of 
my 1904 observations were only in part confirmed. In both years 
the scent was noted in the male only; in 1904 it was described as 
“ like sweet-briar, but sweeter and more luscious,” whereas in 1908 
it was variously described as “sweet,” “very sweet, (?) Freesia,” 
“flowery,” “decided Meadow-sweet,” “decided Stephanotis, ,} “ex¬ 
tremely sweet.” 
Euphina nerissa, Fabr. (India, 1904; Ceylon, 1908). The results 
of many observations were concordant; the males have a distinct 
sweet-briar scent. 
Ganoris napi , Linn. Of this species it is sufficient to say that its 
pleasant and very distinct scent is perhaps the best known of all, as 
it is the easiest to detect. Though very like the scent of Lemon 
Verbena, it is not identical with it. Out of forty-six male specimens 
examined at Mortehoe one summer the scent was present in all, but 
it was not present in any one of thirty-five females examined, though 
I am disposed to think that the female has a very faint scent more 
like that of G. rapae. 
Many times I have known by the scent alone, the moment that 
I have got it into my net, that a small White was a male napi. 
There are but two other butterflies in which I have found the Lemon 
Verbena scent: they are Ganoris melete , Menet., and G. oleracea , Harr., 
butterflies which are usually held to be respectively the Japanese 
and North American forms of G. napi. 
Ganoris rapae , Linn. (England, 1899 (Dixey), 1903, and later). 
There is no manner of doubt that the males of this very familiar 
species also have a scent. But it is not as obvious as in G. napi ; the 
scent is neither as strong nor as distinctive, Originally Dr. Dixey
