 happens that buds arise from the stem close to the foliage 

 leaves.

The President in the Chair. 



The President referred in suitable terms to the death of 

 Mr. N. E. Warne, who for some years was an active member 

 of the Society, and a vote of condolence with his friends was 

 passed. 



Mr. Dennis exhibited a branch of the " tree of Heaven " 

 (Ailantus glanduhsa) , in full flower. He stated that it was 

 introduced into this country from China in 1751, but it was 

 only rarely observed to flower freely. Dr. Chapman said 

 that he had seen several trees in full flower at Reigate Hill 

 this year. 



Mr. R. South exhibited a series of Acidalia virgularia 

 {incanavia), and contributed the following note : " I am ex- 

 hibiting a series of specimens, being part of a brood reared 

 from ova deposited by a female taken at Upper Tooting in 

 September, 1904. The specimens were bred in April, 1905, 

 and are noticeable for their dark colour and large size. The 

 larvae were fed on dandelion, and seemed to prefer it when 

 more or less dry. They did not eat much during the winter, 

 but fed up rapidly in March, and the majority had gone down 

 for pupation by April 4th. Seven moths appeared on April 

 25th, and others, to the number of thirty-five, followed 

 between that date and the end of the month. From eggs 

 laid by some of the females another batch of moths was 

 obtained in July, but all the specimens of this brood were 

 pale and of small size, resembling almost exactly the female 

 September parent of the April moths." 



He also exhibited examples of Rhacodia emargana, with 

 var. caudana, var. effmctana, and var. excavana, together with 

 a series of Coremia unidentaria, and contributed the following 

 note on the latter species : "The series of specimens exhibited 

 has been selected from a larger number reared from a female 

 taken at Oxshott in August, 1904. A good deal of modifica-
