that has been for the last two seasons very destructive to the young leaves of the 

 oak. He had noticed trees 30 or 40 feet high much denuded. It belongs to the 

 same class as the gooseberry fly, and the eggs are laid on the buds or young 

 branches. They hatch in the spring. The larvae at once begin to feed on the 

 young leaves, when full grown fall to the ground, and, hiding in the grass, after a 

 short time emerge as flies, that may be seen at the end of summer in swarms under 

 the trees. The larvae, coiled up, readily fall oS the branches, and may be observed 

 climbing up the trunk of the tree again, if they are so fortunate as to find it, and 

 there is no doubt that multitudes are thus destroyed, especially on a windy day, 

 if accompanied by rain. 



The President brought with him some specimens of a mildew that is at this 

 time attacking the apple trees. It is found on the young leaves, and, from its 

 white mealy appearance, is readily observed. The infected leaf withers, turns 

 brown, hardens, and falls off, all the leaves on the same spray following. Under 

 the microscope the peculiar whiteness is seen to be caused by an infinite number 

 of oval cells, nearly transparent, quite or partially detached from each other, 

 lying loose on both surfaces of the leaf. These are the characters of an Oidium, 

 a very destructive form of fungus belonging to the famDy of " Moulds." Among 

 its relatives are the Oidium Tuckeri, which has been so injurious to the vine, and 

 the Peronospora to the potato. This fungus has appeared in several parts of the 

 kingdom. On the medlar, it had already come under the notice of Dr. Cooke, an 

 expert whom the Club claims as one of its honorary members. He pronounced it 

 to be Oidium Farinosum. 



Mr. Riley, of Putley, exhibited some fine specimens of " Platanthera 

 Chlorantha" (the butterfly orchis), and " Neottia Nidus avis" (the bird's nest 

 orchis).
