Dr. G. B. Longstaff's Bionomic Notes on Butterflies. 621 



sexes the scent was compared to Stephanotis, but in the 

 case of one $ to Frcesia, and in one ^ Mrs. Longstaff 

 thought the odour was " a little bit hair-oily." 



Hehomoia australis, Butl. (Ceylon, 1908). Nine $, all 

 those examined, had a heavy sweet scent, in most cases 

 strong, in all decided : my wife and I compared it to the 

 flowers of mango, or cinnamon. In 3 $ out of 4 there 

 was a similar scent. 



Mejanostoma eerhera, Feld. (Venezuela, 1907). One out 

 of three $ taken is noted as having had " a slight, very 

 sweet scent ; ? clover." 



Ixias cingalensis, Moore (Ceylon, 1908). The 9 $ 

 examined all had a sweet, but only moderately strong 

 scent which reminded me of meadow-scent. Four $ were 

 scentless. 



Papilionin^. 



Ornithoiotcra 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, but I had no opportunity then of confirming his 

 statement. Every ^ that I examined 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 rosemary or " rose-scented 

 hair-oil." Later by the kindness of the Apothecaries Com- 

 pany of Colombo I received through the post a sample of 

 the oil of sassafras, so that I made a direct comparison, 

 \vith the result that the odours of the oil and the butterfly 

 appeared to be almost identical. The $ had an odour 

 like musty straw. 



Papilio hector, Linn. (Ceylon, 1908). The $ has a 

 musty odour. 



Painlio aristolochix, Fabr. (Ceylon, 1908). Both sexes 

 have an odour like musty hay. In the case of a ^ speci- 

 men there is a note : " decided disagreeable smell : ? like 

 new black net." 



Papilio demoleus, Linn., eritJionius, Cram. (Ceylon, 

 1908). A smell like fresh straw was detected in one 

 specimen, a $, in another (a ^ ) there was " a slight 

 peculiar scent in the field : stronger in the house." *

 scent of the allied P. demodocns, Esp.
