cocciiti yahani as an enemy of Ceretvs viridijiorus, and 

 exhibited specimens of both. 



Dr. Malcolm Wilson exhibited a specimen of Melasmia 

 Einpdri, Magn., on Enipetrum nigrum, Linn., collected 

 on Creag na Caillich, Killin. There is little doubt that 

 Rhytisma Empetri, Buchanan White, is identical with this 

 species. Examination shows that no asci are present in 

 Buchanan White's specimens, which were assigned to 

 Rhytisma probably only on account of their external 

 resemblance to that genus,

 of Parasenecio, a new genus of Compositae.

 abnormal ovary of Tulip.
