BIONOMIC NOTES 
compared it to that of Mignonette, but I think all are now agreed 
that Prof. Selwyn Image’s comparison to sweet-briar is better, though 
even that is not exact. 
G-anoris canidia , Sparrm. (India, China, 1903, 1904). The male 
has a scent like that of G. rapae (see especially pp. 98, 127, supra). 
Ganoris brassicae, Linn. (England, 1903, 1904). It is more 
difficult to detect the scent in this than in either of our other common 
Whites, but neither Dr. Dixey nor myself have the slightest doubt 
of its existence. He compared the scent to that of Scarlet Geranium 
petals; I compared it to the flower of Eape. A lady visitor at 
Mortehoe suggested violet-powder— i.e. orris root—which is the best 
comparison. The scent appears to he confined to the male. 
Mylothris agathina , Cram. (S. Africa, 1905). The males of this 
species have a strong, pleasant scent, exactly that of sweet-briar. 
Mylothris riippellii, Koch. (S. Africa, 1905). We could neither 
of us make any distinction between the scent of the males of this 
and the last species. 
Mylothris trimenia , Butl. (S. Africa, 1905). The scent of the 
male is quite distinct from that of the two preceding species. It 
reminded Dr. Dixey of Sweet-pea ; it reminded me of Clover. 
Synchloe hellica, Linn. (S. Africa, 1905). Dr. Dixey compared 
the scent of the males to that of Gorse. I recorded a male as having 
a very slight, heavy, flowery odour. During a passing call at Cape 
Town, in 19D9, I caught a solitary male with a sweet odour which 
seemed to me to have a resinous element. 
Papilioninae. 
Ornithoptera darsius, Gray. (Ceylon, 1908). When at Kandy 
four years previously Mr. W. G. Freedley, junr., told me that the 
males of this species had a scent like Sassafras, hut I had no oppor¬ 
tunity then of confirming his statement. Every male that I ex¬ 
amined during my more recent visit had a scent, some had a strong 
scent. At first I compared this to Cinnamon and to Canada-balsam; 
to Mrs. Longstaff it suggested Eosemary or “ rose-scented hair-oil.” 
Later by the kindness of the Apothecaries’ Company of Colombo I 
received through the post a sample of the oil of Sassafras, so that I 
made a direct comparison, with the result that the odours of the oil 
and the butterfly appeared to be almost identical. The female had 
an odour like musty straw. 
Papilio hector , Linn. (Ceylon, 1908). The male has a musty 
odour. 
Papilio aristolochiae, Fahr. (Assam, 1881). Wood-Mason noted 
in the male a strong and slightly pungent odour resembling that of
