Dr. F A. DiXEY exhibited specimens of South African 

 butteillies captuied by himself and Dr. Lungstaff, and re- 

 mari^ed vipon them as follows : — 



" It may be remembered that at a recent meeting of the 

 Society (Proc. Eiit. Soc. Lond., 1905, pp. liv-lix), I gave some 

 account of the scents observed by us in South African Pierines, 

 calling attention to the fact that they were practically without 

 exception of an agreeable character and confined to the male 

 sex. On the present occasion I wish to speak of the perfumes 

 detected by us in butterflies belonging to other groups ; some 

 of these odours having a similar character to those of the 

 Pierines, while others belong to a different category. 



" Mycalesis sajitza, Hew. (J . On separating the fore- and 

 hind-wings, so as to expose the well-known 'tufts,' I at once 

 perceived a strong odour of chocolate, perhaps combined with 

 a trace of vanilla. This I noted at the time as 'one of the 

 strongest butterfly scents known to me.' I found no odour in 

 the female. Dr. Longstaff also detected a ' chocolate scent, 

 not strong,' in the tufts of the m;de. 



"Two males of Mycalesis j^erspicua, Trim., examined by Dr. 

 Longstaff, emitted a ' very strong treacly odour — quite distinct 

 from the scent of M. sajitza.' To my perception the scent was 

 rather of the chrysipjms orJev, with a suggestion of burnt 

 sugar or treacle. We had no opportunity of testing the 

 female. 



"Two male specimens of YphtJdma itonia, Hew., and three 

 of Vseudonymplia cassias were tested by me with a negative 

 result. 



" The males of Byhlia goetzius, Herbst, yielded a very 

 distinct and agreeable odovir of sweet chocolate, mingled, as in 

 Mycalesis sajitza, with a suggestion of vanilLi. Dr. Longstaff 

 reports a chocolate scent in the only specimen examined by 

 liim — a female. 



" I found a similar chocolate scent in a specimen of Geyenes 

 oculaia, Trim. S . Geyenes zetterstedti, Wallgrn. ? , was 

 odourless, as also w;is a specimen (not yet determined) of 

 Fterygospidea Jlesiis, Fabr. 



" Fla7iema aganice, Hew., has been stated by j\Ir. Marshall 

 (Trans. Ent. Soc. Lend., 1902, p. 413) to have no smell. The
