certain roughness — not, as in G. rapee, the roughness of 

 sweetbriar — and suggested at one time chocolate, at another 

 musk, while itself quite distinct from either. Two females of 

 this species were found to be completely devoid of odour. 

 Dr. Longstaff's results with T. omphale <$ were largely nega- 

 tive. In three specimens, however, he found a fairly strong 

 scent which he compares to that of Freesia or honeysuckle. 



" The scent in Teracolus tone, Godt., $ , cannot always be 

 detected. When present, it is sweet, flowery, and apparently 

 free from all traces of ' snuffiness.' 



" Eronia cleodora, Hiibn., $ . In this form the intensity of 

 the odour varies greatly ; the scent is sometimes absent 

 altogether, but when present may be strong. Its basis is a 

 flowery perfume like that found in many species of Teracolus, 

 but to this is superadded an aromatic element giving a distinct 

 suggestion of sweet chocolate. Dr. Longstaff, who found the 

 scent very faint in all his specimens, considers it to belong to 

 the G. brassies? type. 



" Belenois gidica, Godt., $ , appears in many instances to be 

 without perceptible odour. Occasionally, however, I found it 

 to possess an odour of roses, which in one of my specimens was 

 strong. Dr. Longstaff's results were mainly negative, but in 

 a few instances he reports a slight, sweet flowery perfume. 



" A. specimen of Belenois mesentina, Cram., S , emitted, when 

 fresh, a scent much like that of B. gidica. In a second 

 specimen no odour was detected. 



" Belenois severina, Cram., $ 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. rapse, 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. brassicee, 

 but stronger and more luscious.' I have tested the female, 

 with negative results. 



"Belenois thysa, Hopff., <$ , 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.
