400 Mr. G. Talbot on new 



" With procus it is interesting to note that the male bears a 

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

 particular 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 perhaps 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 priamus and 

 helena."
