400 Mr. G. Talbot on neio 



" Witli i^'t'ocus it is interesting to note that the male bears a 

 delicate perfume which is hard to define. It is not like any 

 pardcular flower, yet is distinctly pleasant to the human 

 sense. Perhaps the best way to describe it is as the scent 

 emanating- from a hothouse of living plants. This charac- 

 teristic is peilia])s not peculiar to procus, but we have never 

 noticed it before in any others. Perhaps it has been over- 

 looked, as the scent is only perceptible on placing the wings 

 fo the nostrils. There is no smell noticeable in j^^'iamus and 

 helena"
